## Description

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.

### The encoding profile serialization format

This is the serialization format of a GstEncodingProfile.

Internally the transcoding application uses GstEncodeBin. gst-validate-transcoding-&GST_API_VERSION; uses its own serialization format to describe the GstEncodeBin.profile property of the encodebin.

The simplest serialized profile looks like:

    1
    muxer_source_caps:videoencoder_source_caps:audioencoder_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 will look like:

    1
    video/webm:video/x-vp8:audio/x-vorbis

You can also set the preset name of the encoding profile using the caps+preset_name syntax as in:

    1
    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:

    1
    video/webm:video/x-vp8|1:audio/x-vorbis

This field allows you to specify how many times maximum a GstEncodingProfile can be used inside an encodebin.

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.

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:

    1
    video/webm:video/x-raw,width=1920,height=1080->video/x-vp8:audio/x-vorbis

#### Some serialized encoding formats examples:

MP3 audio and H264 in MP4:

    1
    video/quicktime,variant=iso:video/x-h264:audio/mpeg,mpegversion=1,layer=3

Vorbis and theora in OGG:

    1
    application/ogg:video/x-theora:audio/x-vorbis

AC3 and H264 in MPEG-TS:

    1
    video/mpegts:video/x-h264:audio/x-ac3
