There are cases where we want to change the restrictions caps during playback, handle that in encodebin. https://bugzilla.gnome.org/show_bug.cgi?id=709588

|
|
* <para>
|
|
* 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.
|
|
* </para>
|
|
* <para>
|
|
* #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.
|
|
* </para>
|
|
* <para>
|
|
* 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.
|
|
* </para>
|
|
* <para>
|
|
* Encoding profiles can be created at runtime by the application or loaded from (and saved
|
|
* to) file using the #GstEncodingTarget API.
