title: Building GStreamer and GStreamer Applications
|
||||
short-description: How to build the GStreamer framework and applications using it.
|
||||
...
|
||||
|
||||
# Building GStreamer on UNIX
|
||||
|
||||
On UNIX, GStreamer uses the standard GNU build system, using autoconf
|
||||
for package configuration and resolving portability issues, automake for
|
||||
building makefiles that comply with the GNU Coding Standards, and
|
||||
libtool for building shared libraries on multiple platforms. The normal
|
||||
sequence for compiling and installing the GStreamer library is thus:
|
||||
`./configure` `make` `make install`
|
||||
|
||||
The standard options provided by GNU autoconf may be passed to the
|
||||
`configure` script. Please see the autoconf documentation or run
|
||||
`./configure --help` for information about the standard options.
|
||||
|
||||
In addition there are several options to activate or deactivate
|
||||
features. E.g. passing `--disable-gst-debug` to `configure` will turn
|
||||
the debugging subsystem into a non-functional stub and remove all macro
|
||||
based invocations from within the library (and anything compiled against
|
||||
the library afterwards.)
|
||||
|
||||
If library size matters and one builds in a controlled environment, it
|
||||
is also possible to totally remove subsystem code. This is intentionally
|
||||
not offered as a configure option as it causes an ABI break. Code built
|
||||
against a version of GStreamer without these modifications needs to be
|
||||
recompiled.
|
||||
`make CFLAGS="-DGST_REMOVE_DEPRECATED -DGST_REMOVE_DISABLED"`
|
||||
|
||||
- `GST_REMOVE_DEPRECATED` - Omit deprecated functions from the
|
||||
library.
|
||||
|
||||
- `GST_REMOVE_DISABLED` - Omit stubs for disabled subsystems from the
|
||||
library.
|
||||
|
||||
# Building GStreamer Applications
|
||||
|
||||
Applications and libraries can use `pkg-config` to get all the needed
|
||||
compiler and linker flags to build against GStreamer. Please note that
|
||||
GStreamer is split into several libraries itself.
|
||||
`pkg-config --list-all | grep gstreamer` will list the available
|
||||
libraries.

|
||||
|
||||
# GStreamer Overview
|
||||
|
||||
GStreamer is a streaming media framework. It uses graphs of elements which operate on data. The functionality to process media is provided by plug-ins which provide features like elements, typefinding, and so on. This allows new functionality to be added simply by installing new plug-ins.

# Running and debugging GStreamer Applications
|
||||
|
||||
## Environment variables
|
||||
|
||||
GStreamer inspects a few of environment variables in addition to
|
||||
standard variables like LANG, PATH or HOME.
|
||||
|
||||
**`GST_PLUGIN_SYSTEM_PATH`, `GST_PLUGIN_SYSTEM_PATH_1_0`.**
|
||||
|
||||
This environment variable can be set to a colon-separated list of paths
|
||||
(or semicolon-separated list on Windows). If this variable is not set,
|
||||
GStreamer will fill in this list for you with
|
||||
|
||||
- plug-ins in the user's home directory, or rather the user's "data
|
||||
home" directory according to the xdg base dir specification.
|
||||
Usually this will be a directory called `plugins` inside the
|
||||
`.local/share/gstreamer-GST_API_VERSION` directory in the user's
|
||||
home directory by default, though this search path may change if the
|
||||
XDG_DATA_HOME environment variable is set.
|
||||
|
||||
- plug-ins installed system-wide. On this system, they are stored in
|
||||
``.
|
||||
|
||||
GStreamer will scan these paths for GStreamer plug-ins. These plug-ins
|
||||
will be loaded after the plug-ins in the GST_PLUGIN_PATH variable
|
||||
below. The paths are scanned in the given order. This allows a user to
|
||||
override system-installed plug-ins with his own versions.
|
||||
|
||||
The GST_PLUGIN_SYSTEM_PATH_1_0 variant is useful if both the old
|
||||
GStreamer 0.10 version and the new GStreamer 1.0 version need to be
|
||||
pointed to new plugin paths. The latter will use the _1_0 variant over
|
||||
the non-versioned one if it is set.
|
||||
|
||||
Setting this variable to an empty string will cause GStreamer not to
|
||||
scan any system paths at all for plug-ins. This can be useful if you're
|
||||
running uninstalled (for development purposes) or while running
|
||||
testsuites.
|
||||
|
||||
**`GST_PLUGIN_PATH`, `GST_PLUGIN_PATH_1_0`.**
|
||||
|
||||
This environment variable can be set to a colon-separated list of paths
|
||||
(or a semicolon-separated list on Windows). GStreamer will scan these
|
||||
paths for GStreamer plug-ins. These plug-ins will be loaded in addition
|
||||
to, and before, the plug-ins in the system paths.
|
||||
|
||||
The GST_PLUGIN_PATH_1_0 variant is useful if both the old GStreamer
|
||||
0.10 version and the new GStreamer 1.0 version need to be pointed to new
|
||||
plugin paths. The latter will use the `_1_0` variant over the
|
||||
non-versioned one if it is set.
|
||||
|
||||
**`GST_DEBUG.`**
|
||||
|
||||
If GStreamer has been configured with `--enable-gst-debug=yes`, this
|
||||
variable can be set to a list of debug options, which cause GStreamer to
|
||||
print out different types of debugging information to stderr.
|
||||
|
||||
The variable takes a comma-separated list of `category_name:level`
|
||||
pairs to set specific levels for the individual categories. The level
|
||||
value ranges from 0 (nothing) to 9 (MEMDUMP).
|
||||
|
||||
1 - `ERROR`
|
||||
|
||||
: Logs all fatal errors. These are errors that do not allow the core
|
||||
or elements to perform the requested action. The application can
|
||||
still recover if programmed to handle the conditions that triggered
|
||||
the error.
|
||||
|
||||
2 - `WARNING`
|
||||
|
||||
: Logs all warnings. Typically these are non-fatal, but user-visible
|
||||
problems are expected to happen.
|
||||
|
||||
3 - `FIXME`
|
||||
|
||||
: Logs all fixme messages. Fixme messages are messages that indicate
|
||||
that something in the executed code path is not fully implemented or
|
||||
handled yet. The purpose of this message is to make it easier to
|
||||
spot incomplete/unfinished pieces of code when reading the debug
|
||||
log.
|
||||
|
||||
4 - `INFO`
|
||||
|
||||
: Logs all informational messages. These are typically used for events
|
||||
in the system that only happen once, or are important and rare
|
||||
enough to be logged at this level.
|
||||
|
||||
5 - `DEBUG`
|
||||
|
||||
: Logs all debug messages. These are general debug messages for events
|
||||
that happen only a limited number of times during an object's
|
||||
lifetime; these include setup, teardown, change of parameters, ...
|
||||
|
||||
6 - `LOG`
|
||||
|
||||
: Logs all log messages. These are messages for events that happen
|
||||
repeatedly during an object's lifetime; these include streaming and
|
||||
steady-state conditions.
|
||||
|
||||
7 - `TRACE`
|
||||
|
||||
: Logs all trace messages. These messages for events that happen
|
||||
repeatedly during an object's lifetime such as the ref/unref
|
||||
cycles.
|
||||
|
||||
9 - `MEMDUMP`
|
||||
|
||||
: Log all memory dump messages. Memory dump messages are used to log
|
||||
(small) chunks of data as memory dumps in the log. They will be
|
||||
displayed as hexdump with ASCII characters.
|
||||
|
||||
The category_name can contain "`*"` as a wildcard.
|
||||
|
||||
For example, setting `GST_DEBUG` to `GST_AUTOPLUG:6,GST_ELEMENT_*:4`,
|
||||
will cause the `GST_AUTOPLUG` category to be logged at full `LOG` level,
|
||||
while all categories starting with `GST_ELEMENT_` will be logged at
|
||||
`INFO` level.
|
||||
|
||||
To get all possible debug output, set `GST_DEBUG` to `*:9`. For debugging
|
||||
purposes a `*:6` debug log is usually the most useful, as it contains
|
||||
all important information, but hides a lot of noise such as refs/unrefs.
|
||||
For bug reporting purposes, a `*:6` log is also what will be requested
|
||||
usually. It's often also worth running with `*:3` to see if there are
|
||||
any non-fatal errors or warnings that might be related to the problem at
|
||||
hand.
|
||||
|
||||
Since GStreamer 1.2 it is also possible to specify debug levels by name,
|
||||
e.g. `GST_DEBUG=*:WARNING,*audio*:LOG`
|
||||
|
||||
**`GST_DEBUG_NO_COLOR.*`*
|
||||
|
||||
Set this environment variable to any value ("1" typically) to switch
|
||||
off colouring in `GST_DEBUG` output. This has the same effect as
|
||||
specifying the `--gst-debug-no-color` or `--gst-debug-color-mode`=off
|
||||
command line option to well-behaved GStreamer applications (ie. those
|
||||
that pass command-line options correctly to GStreamer). This is
|
||||
particularly useful to reduce the size of debug output and also allows
|
||||
for the output to be compressed much better than with colours turned on.
|
||||
|
||||
Has the same effect as setting `GST_DEBUG_COLOR_MODE` environment
|
||||
variable to "off".
|
||||
|
||||
**`GST_DEBUG_COLOR_MODE.`**
|
||||
|
||||
Set this environment variable to change log colouring in `GST_DEBUG` output.
|
||||
Possible values:
|
||||
|
||||
`on`: Enables debug log output coloring. Uses default coloring method for
|
||||
current platform. This is the default.
|
||||
|
||||
`off`: Disables debug log output coloring. This has the same effect as
|
||||
specifying the `--gst-debug-color-mode=off` command line option to well-behaved
|
||||
GStreamer applications (ie. those that pass command-line options correctly to
|
||||
GStreamer). This is particularly useful to reduce the size of debug output and
|
||||
also allows for the output to be compressed much better than with colours turned
|
||||
on. Has the same effect as setting `GST_DEBUG_NO_COLOR` environment variable to
|
||||
any value.
|
||||
|
||||
`auto`: Same as `on`.
|
||||
|
||||
`disable`: Same as `off`.
|
||||
|
||||
`unix`: Enables debug log output coloring and forces the use of UNIX termial
|
||||
codes for coloring, even if this method is not normally used on current
|
||||
platform. This has the same effect as specifying the
|
||||
`--gst-debug-color-mode=unix` command line option to well-behaved GStreamer
|
||||
applications (ie. those that pass command-line options correctly to GStreamer).
|
||||
This is particularly useful to dump debug output into a file on non-UNIX
|
||||
platforms to be sent to developers who have viewers that support UNIX terminal
|
||||
codes.
|
||||
|
||||
**`GST_DEBUG_OPTIONS.`**
|
||||
|
||||
This environment variable can be used to tweak the behaviour of the
|
||||
debugging system. Currently the only options supported are
|
||||
"pretty-tags" and "full-tags". In "pretty-tags" mode (the
|
||||
default), taglists in the debug log will be serialized so that only the
|
||||
first few and last few bytes of a buffer-type tag will be serialized
|
||||
into the log, to avoid dumping hundreds of lines of useless output into
|
||||
the log in case of large image tags and the like.
|
||||
|
||||
**`GST_DEBUG_DUMP_DOT_DIR.`**
|
||||
|
||||
Set this environment variable to a path to turn on all
|
||||
`GST_DEBUG_BIN_TO_DOT_FILE` or `GST_DEBUG_BIN_TO_DOT_FILE_WITH_TS` calls and
|
||||
have the dot files in that location.
|
||||
|
||||
This will only work if the application in question makes these calls in
|
||||
strategic places (like when the pipeline state changes or an error
|
||||
occurs). `gst-launch-1,0` is one such application.
|
||||
|
||||
When `gst-launch-1.0` changes state through NULL to PLAYING
|
||||
and back to NULL, a dot file is generated on each state change. To have
|
||||
`gst-launch-1.0` write a snapshot of the pipeline state,
|
||||
send a SIGHUP to the `gst-launch-1.0` process.
|
||||
|
||||
These .dot files can then be turned into images using the 'dot'
|
||||
utility from the graphviz set of tools, like this:
|
||||
`dot foo.dot -Tsvg -o foo.svg` or `dot foo.dot -Tpng -o foo.png` or
|
||||
`dot foo.dot -Tjpg -o foo.jpg`.
|
||||
|
||||
There is also a utility called `xdot` which allows you to view the dot
|
||||
file directly without converting it first.
|
||||
|
||||
**`GST_REGISTRY`, `GST_REGISTRY_1_0`.**
|
||||
|
||||
Set this environment variable to make GStreamer use a different file for
|
||||
the plugin cache / registry than the default one. This is useful when
|
||||
operating in a separate environment which should not affect the default
|
||||
cache in the user's home directory.
|
||||
|
||||
**`GST_REGISTRY_FORK`.**
|
||||
|
||||
Set this environment variable to "no" to prevent GStreamer from
|
||||
forking on startup in order to update the plugin registry. This is
|
||||
useful for debugging purposes, but should not be used under normal
|
||||
circumstances, since it means that plugins may be loaded into memory
|
||||
even if they are not needed by the application.
|
||||
|
||||
**`GST_REGISTRY_UPDATE`.**
|
||||
|
||||
Set this environment variable to "no" to prevent GStreamer from
|
||||
updating the plugin registry. This is useful for embedded device which
|
||||
is not updating the plugins frequently, it will save time when doing
|
||||
`gst_init()`.
|
||||
|
||||
**GST_TRACE.**
|
||||
|
||||
Enable memory allocation tracing. Most GStreamer objects have support
|
||||
for tracing the number of unfreed objects and their memory pointers.
|
||||
|
||||
The variable takes a comma-separated list of tracing options to enable.
|
||||
|
||||
live
|
||||
|
||||
: Counts all live objects and dumps an overview of the number of
|
||||
unfreed objects at program exit.
|
||||
|
||||
mem-live
|
||||
|
||||
: Keep track of the unfreed memory pointers and dump an overview of
|
||||
all unfreed memory at program exit. Together with a level 9 debug
|
||||
log this can be used to follow the lifecycle of leaked objects in
|
||||
order to track down where they are leaked. This can be useful for
|
||||
debugging memory leaks in situations where tools such as valgrind
|
||||
are not available, or not an option.
|
||||
|
||||
Use `all` to enable all tracing flags.
|
||||
|
||||
**`GST_DEBUG_FILE`.**
|
||||
|
||||
Set this variable to a file path to redirect all GStreamer debug
|
||||
messages to this file. If left unset, debug messages with be output unto
|
||||
the standard error.
|
||||
|
||||
**`ORC_CODE`.**
|
||||
|
||||
Useful Orc environment variable. Set `ORC_CODE=debug` to enable debuggers
|
||||
such as gdb to create useful backtraces from Orc-generated code. Set
|
||||
`ORC_CODE=backup` or `ORC_CODE=emulate` if you suspect Orc's SIMD code
|
||||
generator is producing incorrect code (Quite a few important GStreamer
|
||||
plugins like videotestsrc, audioconvert or audioresample use Orc). One
|
||||
can also combine flags like `ORC_CODE=backup,debug`.
|
||||
|
||||
**`G_DEBUG`.**
|
||||
|
||||
Useful GLib environment variable. Set `G_DEBUG=fatal_warnings` to make
|
||||
GStreamer programs abort when a critical warning such as an assertion
|
||||
failure occurs. This is useful if you want to find out which part of the
|
||||
code caused that warning to be triggered and under what circumstances.
|
||||
Simply set `G_DEBUG` as mentioned above and run the program in gdb (or
|
||||
let it core dump). Then get a stack trace in the usual way.
|
||||
|
||||
**`G_SLICE`.**
|
||||
|
||||
Useful GLib environment variable. Set `G_SLICE=always-malloc` when
|
||||
running GStreamer programs in valgrind, or debugging memory leaks with
|
||||
other tools. See the GLib API reference for more details.
|
||||
|
||||
**`GST_TAG_ENCODING`.**
|
||||
|
||||
Try this character encoding first for tag-related strings where the
|
||||
encoding is not defined and which are not UTF-8 already. By default the
|
||||
current locale will be tried (if not UTF-8).
|
||||
|
||||
**`GST_TAG_ID3_ENCODING`.**
|
||||
|
||||
Try this character encoding first for ID3 tag-related strings where the
|
||||
encoding is not defined and which are not UTF-8 already. By default the
|
||||
current locale will be tried (if not UTF-8).
|
||||
|
||||
**`GST_TAG_ID3V1_ENCODING`.**
|
||||
|
||||
Try this character encoding first for ID3v1 tag-related strings where
|
||||
the encoding does not look like UTF-8.
|
||||
|
||||
**`GST_GL_WINDOW`.**
|
||||
|
||||
Influences the window system to use by the GStreamer OpenGL library.
|
||||
Common values are 'x11', 'wayland', 'win32' or 'cocoa'.
|
||||
|
||||
**`GST_GL_PLATFORM`.**
|
||||
|
||||
Influences the OpenGL platform to use by the GStreamer OpenGL library.
|
||||
Common values are 'egl', 'glx', 'wgl' or 'cgl'.
|
||||
|
||||
**`GST_GL_API`.**
|
||||
|
||||
Influences the OpenGL API requested by the OpenGL platform. Common
|
||||
values are 'opengl' or 'gles2'.

# GStreamer Core
|
||||
|
||||
GStreamer is a streaming media framework. It uses graphs of elements
|
||||
which operate on data. The functionality to process media is provided by
|
||||
plug-ins which provide features like elements, typefinding, and so on.
|
||||
This allows new functionality to be added simply by installing new
|
||||
plug-ins.
|
||||
|
||||
GStreamer is cross-platform and works on most UNIX-like platforms as
|
||||
well as Windows. It is released under the GNU Library General Public
|
||||
License (GNU LGPL).
|
||||
|
||||

|
||||

||||

|
||||
|
||||
## Building on UNIX
|
||||
|
||||
On UNIX, GStreamer uses the standard GNU build system, using autoconf
|
||||
for package configuration and resolving portability issues, automake for
|
||||
building makefiles that comply with the GNU Coding Standards, and
|
||||
libtool for building shared libraries on multiple platforms. The normal
|
||||
sequence for compiling and installing the GStreamer library is thus:
|
||||
`./configure` `make` `make install`
|
||||
|
||||
The standard options provided by GNU autoconf may be passed to the
|
||||
`configure` script. Please see the autoconf documentation or run
|
||||
`./configure --help` for information about the standard options.
|
||||
|
||||
In addition there are several options to activate or deactivate
|
||||
features. E.g. passing `--disable-gst-debug` to `configure` will turn
|
||||
the debugging subsystem into a non-functional stub and remove all macro
|
||||
based invocations from within the library (and anything compiled against
|
||||
the library afterwards.)
|
||||
|
||||
If library size matters and one builds in a controlled environment, it
|
||||
is also possible to totally remove subsystem code. This is intentionally
|
||||
not offered as a configure option as it causes an ABI break. Code built
|
||||
against a version of GStreamer without these modifications needs to be
|
||||
recompiled.
|
||||
|
||||
`make CFLAGS="-DGST_REMOVE_DEPRECATED -DGST_REMOVE_DISABLED"`
|
||||
|
||||
- `GST_REMOVE_DEPRECATED` - Omit deprecated functions from the
|
||||
library.
|
||||
|
||||
- `GST_REMOVE_DISABLED` - Omit stubs for disabled subsystems from the
|
||||
library.
|
||||
|
||||
## Building GStreamer Applications
|
||||
|
||||
Applications and libraries can use `pkg-config` to get all the needed
|
||||
compiler and linker flags to build against GStreamer. Please note that
|
||||
GStreamer is split into several libraries itself.
|
||||
`pkg-config --list-all | grep gstreamer` will list the available
|
||||
libraries.
|
||||
|
||||
## Running and debugging GStreamer Applications
|
||||
|
||||
### Environment variables
|
||||
|
||||
GStreamer inspects a few of environment variables in addition to
|
||||
standard variables like LANG, PATH or HOME.
|
||||
|
||||
**GST_PLUGIN_SYSTEM_PATH, GST_PLUGIN_SYSTEM_PATH_1_0.**
|
||||
|
||||
This environment variable can be set to a colon-separated list of paths
|
||||
(or semicolon-separated list on Windows). If this variable is not set,
|
||||
GStreamer will fill in this list for you with
|
||||
|
||||
- plug-ins in the user's home directory, or rather the user's "data
|
||||
home" directory according to the xdg base dir specification. Usually
|
||||
this will be a directory called `plugins` inside the
|
||||
`.local/share/gstreamer-GST_API_VERSION` directory in the user's
|
||||
home directory by default, though this search path may change if the
|
||||
XDG_DATA_HOME environment variable is set.
|
||||
|
||||
- plug-ins installed system-wide. On this system, they are stored in
|
||||
`GST_PLUGINS_DIR`.
|
||||
|
||||
GStreamer will scan these paths for GStreamer plug-ins. These plug-ins
|
||||
will be loaded after the plug-ins in the GST_PLUGIN_PATH variable
|
||||
below. The paths are scanned in the given order. This allows a user to
|
||||
override system-installed plug-ins with his own versions.
|
||||
|
||||
The GST_PLUGIN_SYSTEM_PATH_1_0 variant is useful if both the old
|
||||
GStreamer 0.10 version and the new GStreamer 1.0 version need to be
|
||||
pointed to new plugin paths. The latter will use the _1_0 variant over
|
||||
the non-versioned one if it is set.
|
||||
|
||||
Setting this variable to an empty string will cause GStreamer not to
|
||||
scan any system paths at all for plug-ins. This can be useful if you're
|
||||
running uninstalled (for development purposes) or while running
|
||||
testsuites.
|
||||
|
||||
**GST_PLUGIN_PATH, GST_PLUGIN_PATH_1_0.**
|
||||
|
||||
This environment variable can be set to a colon-separated list of paths
|
||||
(or a semicolon-separated list on Windows). GStreamer will scan these
|
||||
paths for GStreamer plug-ins. These plug-ins will be loaded in addition
|
||||
to, and before, the plug-ins in the system paths.
|
||||
|
||||
The GST_PLUGIN_PATH_1_0 variant is useful if both the old GStreamer
|
||||
0.10 version and the new GStreamer 1.0 version need to be pointed to new
|
||||
plugin paths. The latter will use the _1_0 variant over the
|
||||
non-versioned one if it is set.
|
||||
|
||||
**GST_DEBUG.**
|
||||
|
||||
If GStreamer has been configured with `--enable-gst-debug=yes`, this
|
||||
variable can be set to a list of debug options, which cause GStreamer to
|
||||
print out different types of debugging information to stderr.
|
||||
|
||||
The variable takes a comma-separated list of "category_name:level"
|
||||
pairs to set specific levels for the individual categories. The level
|
||||
value ranges from 0 (nothing) to 9 (MEMDUMP).
|
||||
|
||||
* 1 - `ERROR`: Logs all fatal errors. These are errors that do not allow the core
|
||||
or elements to perform the requested action. The application can
|
||||
still recover if programmed to handle the conditions that triggered
|
||||
the error.
|
||||
* 2 - `WARNING`: Logs all warnings. Typically these are non-fatal, but user-visible
|
||||
problems are expected to happen.
|
||||
* 3 - `FIXME`: Logs all fixme messages. Fixme messages are messages that indicate
|
||||
that something in the executed code path is not fully implemented or
|
||||
handled yet. The purpose of this message is to make it easier to
|
||||
spot incomplete/unfinished pieces of code when reading the debug
|
||||
log.
|
||||
* 4 - `INFO`: Logs all informational messages. These are typically used for events
|
||||
in the system that only happen once, or are important and rare
|
||||
enough to be logged at this level.
|
||||
* 5 - `DEBUG`: Logs all debug messages. These are general debug messages for events
|
||||
that happen only a limited number of times during an object's
|
||||
lifetime; these include setup, teardown, change of parameters, ...
|
||||
* 6 - `LOG`: Logs all log messages. These are messages for events that happen
|
||||
repeatedly during an object's lifetime; these include streaming and
|
||||
steady-state conditions.
|
||||
* 7 - `TRACE`: Logs all trace messages. These messages for events that happen
|
||||
repeatedly during an object's lifetime such as the ref/unref cycles.
|
||||
* 9 - `MEMDUMP`: Log all memory dump messages. Memory dump messages are used to log
|
||||
(small) chunks of data as memory dumps in the log. They will be
|
||||
displayed as hexdump with ASCII characters.
|
||||
|
||||
The category_name can contain "`*"` as a wildcard.
|
||||
|
||||
For example, setting GST_DEBUG to `GST_AUTOPLUG:6,GST_ELEMENT_*:4`,
|
||||
will cause the `GST_AUTOPLUG` category to be logged at full `LOG` level,
|
||||
while all categories starting with `GST_ELEMENT_` will be logged at
|
||||
`INFO` level.
|
||||
|
||||
To get all possible debug output, set GST_DEBUG to `*:9`. For debugging
|
||||
purposes a `*:6` debug log is usually the most useful, as it contains
|
||||
all important information, but hides a lot of noise such as refs/unrefs.
|
||||
For bug reporting purposes, a `*:6` log is also what will be requested
|
||||
usually. It's often also worth running with `*:3` to see if there are
|
||||
any non-fatal errors or warnings that might be related to the problem at
|
||||
hand.
|
||||
|
||||
Since GStreamer 1.2 it is also possible to specify debug levels by name,
|
||||
e.g. GST_DEBUG=*:WARNING,*audio*:LOG
|
||||
|
||||
**GST_DEBUG_NO_COLOR.**
|
||||
|
||||
Set this environment variable to any value ("1" typically) to switch off
|
||||
colouring in GST_DEBUG output. This has the same effect as specifying
|
||||
the `--gst-debug-no-color` or `--gst-debug-color-mode`=off command line
|
||||
option to well-behaved GStreamer applications (ie. those that pass
|
||||
command-line options correctly to GStreamer). This is particularly
|
||||
useful to reduce the size of debug output and also allows for the output
|
||||
to be compressed much better than with colours turned on.
|
||||
|
||||
Has the same effect as setting GST_DEBUG_COLOR_MODE environment
|
||||
variable to "off".
|
||||
|
||||
**GST_DEBUG_COLOR_MODE.**
|
||||
|
||||
Set this environment variable to change log colouring in GST_DEBUG
|
||||
output. Possible values:
|
||||
|
||||
* `on`: Enables debug log output coloring. Uses default coloring method for
|
||||
current platform. This is the default.
|
||||
* `off`: Disables debug log output coloring. This has the same effect as
|
||||
specifying the `--gst-debug-color-mode`=off command line option to
|
||||
well-behaved GStreamer applications (ie. those that pass
|
||||
command-line options correctly to GStreamer). This is particularly
|
||||
useful to reduce the size of debug output and also allows for the
|
||||
output to be compressed much better than with colours turned on.
|
||||
|
||||
Has the same effect as setting GST_DEBUG_NO_COLOR environment
|
||||
variable to any value.
|
||||
* `auto`: Same as `on`.
|
||||
* `disable`: Same as `off`.
|
||||
* `unix`: Enables debug log output coloring and forces the use of UNIX termial
|
||||
codes for coloring, even if this method is not normally used on
|
||||
current platform. This has the same effect as specifying the
|
||||
`--gst-debug-color-mode`=unix command line option to well-behaved
|
||||
GStreamer applications (ie. those that pass command-line options
|
||||
correctly to GStreamer). This is particularly useful to dump debug
|
||||
output into a file on non-UNIX platforms to be sent to developers
|
||||
who have viewers that support UNIX terminal codes.
|
||||
|
||||
**GST_DEBUG_OPTIONS.**
|
||||
|
||||
This environment variable can be used to tweak the behaviour of the
|
||||
debugging system. Currently the only options supported are "pretty-tags"
|
||||
and "full-tags". In "pretty-tags" mode (the default), taglists in the
|
||||
debug log will be serialized so that only the first few and last few
|
||||
bytes of a buffer-type tag will be serialized into the log, to avoid
|
||||
dumping hundreds of lines of useless output into the log in case of
|
||||
large image tags and the like.
|
||||
|
||||
**GST_DEBUG_DUMP_DOT_DIR.**
|
||||
|
||||
Set this environment variable to a path to turn on all
|
||||
#GST_DEBUG_BIN_TO_DOT_FILE or
|
||||
#GST_DEBUG_BIN_TO_DOT_FILE_WITH_TS calls and have the dot files
|
||||
in that location.
|
||||
|
||||
This will only work if the application in question makes these calls in
|
||||
strategic places (like when the pipeline state changes or an error
|
||||
occurs). gst-launch-GST_API_VERSION is one such application.
|
||||
|
||||
These .dot files can then be turned into images using the 'dot' utility
|
||||
from the graphviz set of tools, like this:
|
||||
`dot foo.dot -Tsvg -o foo.svg` or `dot foo.dot -Tpng -o foo.png` or
|
||||
`dot foo.dot -Tjpg -o foo.jpg`.
|
||||
|
||||
There is also a utility called `xdot` which allows you to view the dot
|
||||
file directly without converting it first.
|
||||
|
||||
**GST_REGISTRY, GST_REGISTRY_1_0.**
|
||||
|
||||
Set this environment variable to make GStreamer use a different file for
|
||||
the plugin cache / registry than the default one. This is useful when
|
||||
operating in a separate environment which should not affect the default
|
||||
cache in the user's home directory.
|
||||
|
||||
**GST_REGISTRY_FORK.**
|
||||
|
||||
Set this environment variable to "no" to prevent GStreamer from forking
|
||||
on startup in order to update the plugin registry. This is useful for
|
||||
debugging purposes, but should not be used under normal circumstances,
|
||||
since it means that plugins may be loaded into memory even if they are
|
||||
not needed by the application.
|
||||
|
||||
**GST_REGISTRY_UPDATE.**
|
||||
|
||||
Set this environment variable to "no" to prevent GStreamer from updating
|
||||
the plugin registry. This is useful for embedded device which is not
|
||||
updating the plugins frequently, it will save time when doing
|
||||
gst_init().
|
||||
|
||||
**GST_TRACE.**
|
||||
|
||||
Enable memory allocation tracing. Most GStreamer objects have support
|
||||
for tracing the number of unfreed objects and their memory pointers.
|
||||
|
||||
The variable takes a comma-separated list of tracing options to enable.
|
||||
|
||||
* live: Counts all live objects and dumps an overview of the number of
|
||||
unfreed objects at program exit.
|
||||
|
||||
* mem-live: Keep track of the unfreed memory pointers and dump an overview of
|
||||
all unfreed memory at program exit. Together with a level 9 debug
|
||||
log this can be used to follow the lifecycle of leaked objects in
|
||||
order to track down where they are leaked. This can be useful for
|
||||
debugging memory leaks in situations where tools such as valgrind
|
||||
are not available, or not an option.
|
||||
|
||||
Use `all` to enable all tracing flags.
|
||||
|
||||
**GST_DEBUG_FILE.**
|
||||
|
||||
Set this variable to a file path to redirect all GStreamer debug
|
||||
messages to this file. If left unset, debug messages with be output unto
|
||||
the standard error.
|
||||
|
||||
**ORC_CODE.**
|
||||
|
||||
Useful Orc environment variable. Set ORC_CODE=debug to enable debuggers
|
||||
such as gdb to create useful backtraces from Orc-generated code. Set
|
||||
ORC_CODE=backup or ORC_CODE=emulate if you suspect Orc's SIMD code
|
||||
generator is producing incorrect code (Quite a few important GStreamer
|
||||
plugins like videotestsrc, audioconvert or audioresample use Orc). One
|
||||
can also combine flags like ORC_CODE=backup,debug.
|
||||
|
||||
**G_DEBUG.**
|
||||
|
||||
Useful GLib environment variable. Set G_DEBUG=fatal_warnings to make
|
||||
GStreamer programs abort when a critical warning such as an assertion
|
||||
failure occurs. This is useful if you want to find out which part of the
|
||||
code caused that warning to be triggered and under what circumstances.
|
||||
Simply set G_DEBUG as mentioned above and run the program in gdb (or
|
||||
let it core dump). Then get a stack trace in the usual way.
|
||||
|
||||
**G_SLICE.**
|
||||
|
||||
Useful GLib environment variable. Set G_SLICE=always-malloc when
|
||||
running GStreamer programs in valgrind, or debugging memory leaks with
|
||||
other tools. See the GLib API reference for more details.
|
||||
|
||||
**GST_TAG_ENCODING.**
|
||||
|
||||
Try this character encoding first for tag-related strings where the
|
||||
encoding is not defined and which are not UTF-8 already. By default the
|
||||
current locale will be tried (if not UTF-8).
|
||||
|
||||
**GST_TAG_ID3_ENCODING.**
|
||||
|
||||
Try this character encoding first for ID3 tag-related strings where the
|
||||
encoding is not defined and which are not UTF-8 already. By default the
|
||||
current locale will be tried (if not UTF-8).
|
||||
|
||||
**GST_TAG_ID3V1_ENCODING.**
|
||||
|
||||
Try this character encoding first for ID3v1 tag-related strings where
|
||||
the encoding does not look like UTF-8.
|
||||
|
||||
**GST_GL_WINDOW.**
|
||||
|
||||
Influences the window system to use by the GStreamer OpenGL library.
|
||||
Common values are 'x11', 'wayland', 'win32' or 'cocoa'.
|
||||
|
||||
**GST_GL_PLATFORM.**
|
||||
|
||||
Influences the OpenGL platform to use by the GStreamer OpenGL library.
|
||||
Common values are 'egl', 'glx', 'wgl' or 'cgl'.
|
||||
|
||||
**GST_GL_API.**
|
||||
|
||||
Influences the OpenGL API requested by the OpenGL platform. Common
|
||||
values are 'opengl' or 'gles2'.
