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 the `presence` property of an * encoding profile using the `|presence` syntax as in: * * |[ * video/webm:video/x-vp8|1: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->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->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 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 * ]| * * # Example: Creating a profile * * |[ * #include * ... * 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 * * |[ * #include * ... * 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, "theorapreset", 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; *} * * ]| * * # Example: Listing categories, targets and profiles * * |[ * #include * ... * GstEncodingProfile *prof; * GList *categories, *tmpc; * GList *targets, *tmpt; * ... * categories = gst_encoding_list_available_categories (); * * ...
