|
*
|
|
* 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)
|
|
* * `|factory-name=element-factory-name` (See #gst_encoding_profile_set_preset_name)
|
|
*
|
|
* 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
|
|
*
|
|
* ### Creating a profile
|
|
*
|
|
* ``` c
|
|
* #include <gst/pbutils/encoding-profile.h>
|
|
* ...
|
|
* 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 <gst/pbutils/encoding-profile.h>
|
|
* ...
|
|
* GstEncodingProfile *
|
|
* create_ogg_theora_profile(void)
|

* 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;
|
|
*}
|
|
*
|
|
* ```
|

|
|

|
|
* GList *categories, *tmpc;

|
|
* ...
|
|

|
|
*
|
|
* for (tmpc = categories; tmpc; tmpc = tmpc->next) {
|
|
* gchar *category = (gchar *) tmpc->data;
|
|
*
|
|
* ... and we can list all targets within that category ...
|
|
*
|
|
