<doc xml:space="preserve">Constant that defines the caps feature name for DMA buffer sharing.
It has to be used for non-mappable dma-buf only, i.e. when the underlying
memory is not mappable to user space. Or when the mapped memory contains
non meaningful data. It can be the case for protected content or when the
user wants explicitly avoid any software post processing.
In these cases all elements between the exported and the importer has to work
in passthrough mode. This is done by adding this caps feature.
When the memory is mappable for read and write requests then it is assumes
to be a fast path and so this caps feature should not be used. Though
according to the dma-buf protocol, while it is mapped it prevents the
exporter to migrate the buffer.
This caps feature should not serve at all the purpose of selecting the
@GST_ALLOCATOR_DMABUF allocator during caps negotiation.
When the exporter is the upstream element from the importer point of view,
the exporter should try to map the dma buffer at runtime (preferably during
decide_allocation phase). When it succeeds for #GST_MAP_READWRITE this caps
feature should not be used. This allows scalers, color converts and any image
processing filters to work directly on the dma buffer.
In this case the importer element should check all incoming memory using
gst_is_dmabuf_memory().</doc>

<doc xml:space="preserve">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.
Unlike other systems, the encoding profiles do not specify which #GstElement
to use for the various encoding and muxing steps, but instead relies on
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.
## Defining a GstEncodingProfile as a string
### Serialized encoding profile formats
#### 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.
### Advanced encoding format serialization features:
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
```
Moreover, you can set extra properties `presence`, `single-segment` and
`variable-framerate` * of an * encoding profile using the `|presence=` syntax
as in:
```
video/webm:video/x-vp8|presence=1,variable-framerate=true|single-segment=true:audio/x-vorbis
```
This field allows specifies the maximum number of times a
#GstEncodingProfile can be used inside an encodebin. If 0, it is not a
mandatory stream and can be used as many times as necessary.
You can also use the `restriction_caps-&gt;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. 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-&gt;video/x-vp8:audio/x-vorbis"
```
&gt; NOTE: Make sure to enclose into quotes to avoid '&gt;' to be reinterpreted by
&gt; the shell.
In the case you are using encoder types, 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 where 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
### Creating a profile
``` c
#include &lt;gst/pbutils/encoding-profile.h&gt;
...
GstEncodingProfile *
create_ogg_theora_profile(void)
{
GstEncodingContainerProfile *prof;
GstCaps *caps;
caps = gst_caps_from_string("application/ogg");
prof = gst_encoding_container_profile_new("Ogg audio/video",
"Standard OGG/THEORA/VORBIS",
caps, NULL);
gst_caps_unref (caps);
caps = gst_caps_from_string("video/x-theora");
gst_encoding_container_profile_add_profile(prof,
(GstEncodingProfile*) gst_encoding_video_profile_new(caps, NULL, NULL, 0));
gst_caps_unref (caps);
caps = gst_caps_from_string("audio/x-vorbis");
gst_encoding_container_profile_add_profile(prof,
(GstEncodingProfile*) gst_encoding_audio_profile_new(caps, NULL, NULL, 0));
gst_caps_unref (caps);
return (GstEncodingProfile*) prof;
}
```
### Example: Using an encoder preset with a profile
``` c
#include &lt;gst/pbutils/encoding-profile.h&gt;
...
GstEncodingProfile *
create_ogg_theora_profile(void)
{
GstEncodingVideoProfile *v;
GstEncodingAudioProfile *a;
GstEncodingContainerProfile *prof;
GstCaps *caps;
GstPreset *preset;
caps = gst_caps_from_string ("application/ogg");
prof = gst_encoding_container_profile_new ("Ogg audio/video",
"Standard OGG/THEORA/VORBIS",
caps, NULL);
gst_caps_unref (caps);
preset = GST_PRESET (gst_element_factory_make ("theoraenc", "theorapreset"));
g_object_set (preset, "bitrate", 1000, NULL);
// The preset will be saved on the filesystem,
// so try to use a descriptive name
gst_preset_save_preset (preset, "theora_bitrate_preset");
gst_object_unref (preset);
caps = gst_caps_from_string ("video/x-theora");
v = gst_encoding_video_profile_new (caps, "theora_bitrate_preset", NULL, 0);
gst_encoding_container_profile_add_profile (prof, (GstEncodingProfile*) v);
gst_caps_unref (caps);
caps = gst_caps_from_string ("audio/x-vorbis");
a = gst_encoding_audio_profile_new (caps, NULL, NULL, 0);
gst_encoding_container_profile_add_profile (prof, (GstEncodingProfile*) a);
gst_caps_unref (caps);
return (GstEncodingProfile*) prof;
}
```
### Listing categories, targets and profiles
``` c
#include &lt;gst/pbutils/encoding-profile.h&gt;
...
GstEncodingProfile *prof;
GList *categories, *tmpc;
GList *targets, *tmpt;
...
categories = gst_encoding_list_available_categories ();
... Show available categories to user ...
for (tmpc = categories; tmpc; tmpc = tmpc-&gt;next) {
gchar *category = (gchar *) tmpc-&gt;data;
... and we can list all targets within that category ...
targets = gst_encoding_list_all_targets (category);
... and show a list to our users ...
g_list_foreach (targets, (GFunc) gst_encoding_target_unref, NULL);
g_list_free (targets);
}
g_list_foreach (categories, (GFunc) g_free, NULL);
g_list_free (categories);
...
```</doc>
</docsection>
<docsection name="encoding-target">
<doc xml:space="preserve">On top of the notion of profiles, we implement the notion of EncodingTarget.
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.

<doc xml:space="preserve">libgstpbutils is a general utility library for plugins and applications.
It currently provides the
following:
* human-readable description strings of codecs, elements, sources, decoders,
encoders, or sinks from decoder/encoder caps, element names, or protocol
names.
* support for applications to initiate installation of missing plugins (if
this is supported by the distribution or operating system used)
* API for GStreamer elements to create missing-plugin messages in order to
communicate to the application that a certain type of plugin is missing
(decoder, encoder, URI protocol source, URI protocol sink, named element)
* API for applications to recognise and handle missing-plugin messages
## 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>

</docsection>
<docsection name="gstpbutilsinstallplugins">
<doc xml:space="preserve">## Overview
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.
&gt; A Gtk/GLib main loop must be running in order for the result function
&gt; to be called when the external installer has finished. If this is not
&gt; the case, make sure to regularly call in your code:
&gt;
&gt; 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>
