|
|
information as possible from one or many URIs.
|
|
|
|
It provides two APIs, allowing usage in blocking or non-blocking mode.
|
|
|
|
The blocking mode just requires calling gst_discoverer_discover_uri()
|
|
with the URI one wishes to discover.
|
|
|
|
The non-blocking mode requires a running #GMainLoop iterating a
|
|
#GMainContext, where one connects to the various signals, appends the
|
|
URIs to be processed (through gst_discoverer_discover_uri_async()) and then
|
|
asks for the discovery to begin (through gst_discoverer_start()).
|
|
By default this will use the GLib default main context unless you have
|
|
set a custom context using g_main_context_push_thread_default().
|
|
|
|
All the information is returned in a #GstDiscovererInfo structure.</doc>

<doc xml:space="preserve" filename="../subprojects/gst-plugins-base/gst-libs/gst/pbutils/encoding-profile.c">Functions to create and handle encoding profiles.
|
|
|
|
Encoding profiles describe the media types and settings one wishes to use for
|
|
an encoding process. The top-level profiles are commonly
|
|
#GstEncodingContainerProfile(s) (which contains a user-readable name and
|
|
description along with which container format to use). These, in turn,
|
|
reference one or more #GstEncodingProfile(s) which indicate which encoding
|
|
format should be used on each individual streams.
|
|
|
|
#GstEncodingProfile(s) can be provided to the 'encodebin' element, which will
|
|
take care of selecting and setting up the required elements to produce an
|
|
output stream conforming to the specifications of the profile.
|
|
|
|
The encoding profiles do not necessarily specify which #GstElement to use for
|
|
the various encoding and muxing steps, as they allow to specifying the format
|
|
one wishes to use.
|
|
|
|
Encoding profiles can be created at runtime by the application or loaded from
|
|
(and saved to) file using the #GstEncodingTarget API.
|
|
|
|
## The encoding profile serialization format
|
|
|
|
Encoding profiles can be serialized to be used in the command line tools or
|
|
to set it on other other #GObject-s using #gst_util_set_object_arg for
|
|
example.
|
|
|
|
The serialization format aims at being simple to understand although flexible
|
|
enough to describe any possible encoding profile. There are several ways to
|
|
describe the profile depending on the context but the general idea is that it
|
|
is a colon separated list of EncodingProfiles descriptions, the first one
|
|
needs to describe a #GstEncodingContainerProfile and the following ones
|
|
describe elementary streams.
|
|
|
|
### Using encoders and muxer element factory name
|
|
|
|
```
|
|
muxer_factory_name:video_encoder_factory_name:audio_encoder_factory_name
|
|
```
|
|
|
|
For example to encode a stream into a WebM container, with an OGG audio
|
|
stream and a VP8 video stream, the serialized #GstEncodingProfile looks like:
|
|
|
|
```
|
|
webmmux:vp8enc:vorbisenc
|
|
```
|
|
|
|
### Define the encoding profile in a generic way using caps:
|
|
|
|
```
|
|
muxer_source_caps:video_encoder_source_caps:audio_encoder_source_caps
|
|
```
|
|
|
|
For example to encode a stream into a WebM container, with an OGG audio
|
|
stream and a VP8 video stream, the serialized #GstEncodingProfile looks like:
|
|
|
|
```
|
|
video/webm:video/x-vp8:audio/x-vorbis
|
|
```
|
|
|
|
It is possible to mix caps and element type names so you can specify a
|
|
specific video encoder while using caps for other encoders/muxer.
|
|
|
|
### Using preset
|
|
|
|
You can also set the preset name of the encoding profile using the
|
|
caps+preset_name syntax as in:
|
|
|
|
```
|
|
video/webm:video/x-vp8+youtube-preset:audio/x-vorbis
|
|
```
|
|
|
|
### Setting properties on muxers or on the encoding profile itself
|
|
|
|
Moreover, you can set the extra properties:
|
|
|
|
* `|element-properties,property1=true` (See
|
|
#gst_encoding_profile_set_element_properties)
|
|
* `|presence=true` (See See #gst_encoding_profile_get_presence)
|
|
* `|single-segment=true` (See #gst_encoding_profile_set_single_segment)
|
|
* `|single-segment=true` (See
|
|
#gst_encoding_video_profile_set_variableframerate)
|
|
|
|
for example:
|
|
|
|
```
|
|
video/webm:video/x-vp8|presence=1|element-properties,target-bitrate=500000:audio/x-vorbis
|
|
```
|
|
|
|
### Enforcing properties to the stream itself (video size, number of audio channels, etc..)
|
|
|
|
You can also use the `restriction_caps->encoded_format_caps` syntax to
|
|
specify the restriction caps to be set on a #GstEncodingProfile
|
|
|
|
It corresponds to the restriction #GstCaps to apply before the encoder that
|
|
will be used in the profile (See #gst_encoding_profile_get_restriction). The
|
|
fields present in restriction caps are properties of the raw stream (that is,
|
|
before encoding), such as height and width for video and depth and sampling
|
|
rate for audio. This property does not make sense for muxers. See
|
|
#gst_encoding_profile_get_restriction for more details.
|
|
|
|
To force a video stream to be encoded with a Full HD resolution (using WebM
|
|
as the container format, VP8 as the video codec and Vorbis as the audio
|
|
codec), you should use:
|
|
|
|
```
|
|
"video/webm:video/x-raw,width=1920,height=1080->video/x-vp8:audio/x-vorbis"
|
|
```
|
|
|
|
> NOTE: Make sure to enclose into quotes to avoid '>' to be reinterpreted by
|
|
> the shell.
|
|
|
|
In the case you are specifying encoders directly, the following is also
|
|
possible:
|
|
|
|
```
|
|
matroskamux:x264enc,width=1920,height=1080:audio/x-vorbis
|
|
```
|
|
|
|
## Some serialized encoding formats examples
|
|
|
|
### MP3 audio and H264 in MP4**
|
|
|
|
```
|
|
video/quicktime,variant=iso:video/x-h264:audio/mpeg,mpegversion=1,layer=3
|
|
```
|
|
|
|
### Vorbis and theora in OGG
|
|
|
|
```
|
|
application/ogg:video/x-theora:audio/x-vorbis
|
|
```
|
|
|
|
### AC3 and H264 in MPEG-TS
|
|
|
|
```
|
|
video/mpegts:video/x-h264:audio/x-ac3
|
|
```
|
|
|
|
## Loading a profile from encoding targets
|
|
|
|
Anywhere you have to use a string to define a #GstEncodingProfile, you
|
|
can use load it from a #GstEncodingTarget using the following syntaxes:
|
|
|
|
```
|
|
target_name[/profilename/category]
|
|
```
|
|
|
|
or
|
|
|
|
```
|
|
/path/to/target.gep:profilename
|
|
```
|
|
|
|
## Examples
|
|
|
|

|
|
|
|
``` c

|
|
{

|
|
|
|
caps = gst_caps_from_string("application/ogg");
|
|
prof = gst_encoding_container_profile_new("Ogg audio/video",

|
|
Encoding Targets are basically a higher level of abstraction to define formats
|
|
for specific target types. Those can define several GstEncodingProfiles with
|
|
different names, for example one for transcoding in full HD, another one for
|
|
low res, etc.. which are defined in the same encoding target.
|
|
|
|
Basically if you want to encode a stream to send it to, say, youtube you should
|
|
have a Youtube encoding target defined in the "online-service" category.
|
|
|
|
## Encoding target serialization format
|
|
|
|
Encoding targets are serialized in a KeyFile like files.

following:
|
|
|
|
* human-readable description strings of codecs, elements, sources, decoders,
|
|
encoders, or sinks from decoder/encoder caps, element names, or protocol
|

## Linking to this library
|
|
|
|
You should obtain the required CFLAGS and LIBS using pkg-config on the

gstreamer-plugins-base-1.0 module. You will then also need to add
|
|
'-lgstreamer-pbutils-1.0' manually to your LIBS line.

## Library initialisation
|
|
|
|
Before using any of its functions, applications and plugins must call
|
|
gst_pb_utils_init() to initialise the library.</doc>

|
|
|
|
Using this API, applications can request the installation of missing
|
|
GStreamer plugins. These may be missing decoders/demuxers or
|
|
encoders/muxers for a certain format, sources or sinks for a certain URI
|
|
protocol (e.g. 'http'), or certain elements known by their element
|
|
factory name ('audioresample').
|
|
|
|
Whether plugin installation is supported or not depends on the operating
|
|
system and/or distribution in question. The vendor of the operating
|
|
system needs to make sure the necessary hooks and mechanisms are in
|
|
place for plugin installation to work. See below for more detailed
|
|
information.
|
|
|
|
From the application perspective, plugin installation is usually
|
|
triggered either
|
|
|
|
- when the application itself has found that it wants or needs to
|
|
install a certain element
|
|
- when the application has been notified by an element (such as
|
|
playbin or decodebin) that one or more plugins are missing *and* the
|
|
application has decided that it wants to install one or more of
|
|
those missing plugins
|
|
|
|
The install functions in this section all take one or more 'detail
|
|
strings'. These detail strings contain information about the type of
|
|
plugin that needs to be installed (decoder, encoder, source, sink, or
|
|
named element), and some additional information such GStreamer version
|
|
used and a human-readable description of the component to install for
|
|
user dialogs.
|
|
|
|
Applications should not concern themselves with the composition of the
|
|
string itself. They should regard the string as if it was a shared
|
|
secret between GStreamer and the plugin installer application.
|
|
|
|
Detail strings can be obtained using the function
|
|
gst_missing_plugin_message_get_installer_detail() on a
|
|
missing-plugin message. Such a message will either have been found by
|
|
the application on a pipeline's #GstBus, or the application will have
|
|
created it itself using gst_missing_element_message_new(),
|
|
gst_missing_decoder_message_new(),
|
|
gst_missing_encoder_message_new(),
|
|
gst_missing_uri_sink_message_new(), or
|
|
gst_missing_uri_source_message_new().
|
|
|
|
For each GStreamer element/plugin/component that should be installed,
|
|
the application needs one of those 'installer detail' string mentioned
|
|
in the previous section. This string can be obtained, as already
|
|
mentioned above, from a missing-plugin message using the function
|
|
gst_missing_plugin_message_get_installer_detail(). The
|
|
missing-plugin message is either posted by another element and then
|
|
found on the bus by the application, or the application has created it
|
|
itself as described above.
|
|
|
|
The application will then call gst_install_plugins_async(), passing a
|
|
NULL-terminated array of installer detail strings, and a function that
|
|
should be called when the installation of the plugins has finished
|
|
(successfully or not). Optionally, a #GstInstallPluginsContext created
|
|
with gst_install_plugins_context_new() may be passed as well. This
|
|
way additional optional arguments like the application window's XID can
|
|
be passed to the external installer application.
|
|
|
|
gst_install_plugins_async() will return almost immediately, with the
|
|
return code indicating whether plugin installation was started or not.
|
|
If the necessary hooks for plugin installation are in place and an
|
|
external installer application has in fact been called, the passed in
|
|
function will be called with a result code as soon as the external
|
|
installer has finished. If the result code indicates that new plugins
|
|
have been installed, the application will want to call
|
|
gst_update_registry() so the run-time plugin registry is updated and
|
|
the new plugins are made available to the application.
|
|
|
|
> A Gtk/GLib main loop must be running in order for the result function
|
|
> to be called when the external installer has finished. If this is not
|
|
> the case, make sure to regularly call in your code:
|
|
>
|
|
> g_main_context_iteration (NULL,FALSE);
|
|
|
|
## 1. Installer hook
|
|
|
|
When GStreamer applications initiate plugin installation via
|
|
gst_install_plugins_async() or gst_install_plugins_sync(), a
|
|
pre-defined helper application will be called.
|
|
|
|
The exact path of the helper application to be called is set at compile
|
|
time, usually by the build system based on the install prefix.
|
|
For a normal package build into the `/usr` prefix, this will usually
|
|
default to `/usr/libexec/gst-install-plugins-helper` or
|
|
`/usr/lib/gst-install-plugins-helper`.
|
|
|
|
Vendors/distros who want to support GStreamer plugin installation should
|
|
either provide such a helper script/application or use the meson option
|
|
`-Dinstall_plugins_helper'=/path/to/installer` to make GStreamer call an
|
|
installer of their own directly.
|
|
|
|
It is strongly recommended that vendors provide a small helper
|
|
application as interlocutor to the real installer though, even more so
|
|
if command line argument munging is required to transform the command
|
|
line arguments passed by GStreamer to the helper application into
|
|
arguments that are understood by the real installer.
|
|
|
|
The helper application path defined at compile time can be overridden at
|
|
runtime by setting the GST_INSTALL_PLUGINS_HELPER environment
|
|
variable. This can be useful for testing/debugging purposes.
|
|
|
|
## 2. Arguments passed to the install helper
|
|
|
|
GStreamer will pass the following arguments to the install helper (this
|
|
is in addition to the path of the executable itself, which is by
|
|
convention argv[0]):
|
|
|
|
- none to many optional arguments in the form of `--foo-bar=val`.
|
|
Example: `--transient-for=XID` where XID is the X Window ID of the
|
|
main window of the calling application (so the installer can make
|
|
itself transient to that window). Unknown optional arguments should
|
|
be ignored by the installer.
|
|
|
|
- one 'installer detail string' argument for each plugin to be
|
|
installed; these strings will have a `gstreamer` prefix; the exact
|
|
format of the detail string is explained below
|
|
|
|
## 3. Detail string describing the missing plugin
|
|
|
|
The string is in UTF-8 encoding and is made up of several fields,
|
|
separated by '|' characters (but neither the first nor the last
|
|
character is a '|'). The fields are:
|
|
|
|
- plugin system identifier, ie. "gstreamer"
|
|
This identifier determines the format of the rest of the detail
|
|
string. Automatic plugin installers should not process detail
|
|
strings with unknown identifiers. This allows other plugin-based
|
|
libraries to use the same mechanism for their automatic plugin
|
|
installation needs, or for the format to be changed should it turn
|
|
out to be insufficient.
|
|
- plugin system version, e.g. "1.0"
|
|
This is required so that when there is GStreamer-2.0 at some point
|
|
in future, the different major versions can still co-exist and use
|
|
the same plugin install mechanism in the same way.
|
|
- application identifier, e.g. "totem"
|
|
This may also be in the form of "pid/12345" if the program name
|
|
can't be obtained for some reason.
|
|
- human-readable localised description of the required component, e.g.
|
|
"Vorbis audio decoder"
|
|
- identifier string for the required component (see below for details
|
|
about how to map this to the package/plugin that needs installing),
|
|
e.g.
|
|
- urisource-$(PROTOCOL_REQUIRED), e.g. urisource-http or
|
|
urisource-mms
|
|
- element-$(ELEMENT_REQUIRED), e.g. element-videoconvert
|
|
- decoder-$(CAPS_REQUIRED), e.g. (do read below for more
|
|
details!):
|
|
- decoder-audio/x-vorbis
|
|
- decoder-application/ogg
|
|
- decoder-audio/mpeg, mpegversion=(int)4
|
|
- decoder-video/mpeg, systemstream=(boolean)true,
|
|
mpegversion=(int)2
|
|
- encoder-$(CAPS_REQUIRED), e.g. encoder-audio/x-vorbis
|
|
- optional further fields not yet specified
|
|
|
|
An entire ID string might then look like this, for example: `
|
|
gstreamer|1.0|totem|Vorbis audio decoder|decoder-audio/x-vorbis`
|
|
|
|
Plugin installers parsing this ID string should expect further fields
|
|
also separated by '|' symbols and either ignore them, warn the user, or
|
|
error out when encountering them.
|
|
|
|
Those unfamiliar with the GStreamer 'caps' system should note a few
|
|
things about the caps string used in the above decoder/encoder case:
|
|
|
|
- the first part ("video/mpeg") of the caps string is a GStreamer
|
|
media type and *not* a MIME type. Wherever possible, the GStreamer
|
|
media type will be the same as the corresponding MIME type, but
|
|
often it is not.
|
|
- a caps string may or may not have additional comma-separated fields
|
|
of various types (as seen in the examples above)
|
|
- the caps string of a 'required' component (as above) will always
|
|
have fields with fixed values, whereas an introspected string (see
|
|
below) may have fields with non-fixed values. Compare for example:
|
|
- `audio/mpeg, mpegversion=(int)4` vs.
|
|
`audio/mpeg, mpegversion=(int){2, 4}`
|
|
- `video/mpeg, mpegversion=(int)2` vs.
|
|
`video/mpeg, systemstream=(boolean){ true, false}, mpegversion=(int)[1, 2]`
|
|
|
|
## 4. Exit codes the installer should return
|
|
|
|
The installer should return one of the following exit codes when it
|
|
exits:
|
|
|
|
- 0 if all of the requested plugins could be installed
|
|
(#GST_INSTALL_PLUGINS_SUCCESS)
|
|
- 1 if no appropriate installation candidate for any of the requested
|
|
plugins could be found. Only return this if nothing has been
|
|
installed (#GST_INSTALL_PLUGINS_NOT_FOUND)
|
|
- 2 if an error occurred during the installation. The application will
|
|
assume that the user will already have seen an error message by the
|
|
installer in this case and will usually not show another one
|
|
(#GST_INSTALL_PLUGINS_ERROR)
|
|
- 3 if some of the requested plugins could be installed, but not all
|
|
(#GST_INSTALL_PLUGINS_PARTIAL_SUCCESS)
|
|
- 4 if the user aborted the installation
|
|
(#GST_INSTALL_PLUGINS_USER_ABORT)
|
|
|
|
## 5. How to map the required detail string to packages
|
|
|
|
It is up to the vendor to find mechanism to map required components from
|
|
the detail string to the actual packages/plugins to install. This could
|
|
be a hardcoded list of mappings, for example, or be part of the
|
|
packaging system metadata.
|
|
|
|
GStreamer plugin files can be introspected for this information. The
|
|
`gst-inspect` utility has a special command line option that will output
|
|
information similar to what is required. For example `
|
|
$ gst-inspect-1.0 --print-plugin-auto-install-info /path/to/libgstvorbis.so
|
|
should output something along the lines of
|
|
`decoder-audio/x-vorbis`, `element-vorbisdec` `element-vorbisenc`
|
|
`element-vorbisparse`, `element-vorbistag`, `encoder-audio/x-vorbis`
|
|
|
|
Note that in the encoder and decoder case the introspected caps can be
|
|
more complex with additional fields, e.g.
|
|
`audio/mpeg,mpegversion=(int){2,4}`, so they will not always exactly
|
|
match the caps wanted by the application. It is up to the installer to
|
|
deal with this (either by doing proper caps intersection using the
|
|
GStreamer #GstCaps API, or by only taking into account the media type).
|
|
|
|
Another potential source of problems are plugins such as ladspa or
|
|
libvisual where the list of elements depends on the installed
|
|
ladspa/libvisual plugins at the time. This is also up to the
|
|
distribution to handle (but usually not relevant for playback
|
|
applications).</doc>

Missing-plugin messages are posted on the bus by elements like decodebin

installed or installation has failed, @func will be called with the result

This function requires a running GLib/Gtk main loop. If you are not

running a GLib/Gtk main loop, make sure to regularly call

g_main_context_iteration(NULL,FALSE).
|
|
|

The installer strings that make up @detail are typically obtained by
|
|
calling gst_missing_plugin_message_get_installer_detail() on missing-plugin
|
|
messages that have been caught on a pipeline's bus or created by the
|
|
application via the provided API, such as gst_missing_element_message_new().
|
|
|
|
It is possible to request the installation of multiple missing plugins in
|
|
one go (as might be required if there is a demuxer for a certain format
|
|
installed but no suitable video decoder and no suitable audio decoder).</doc>
