* Information about the caps fields:
*
* header-format:
* none: No codec_data and only in-stream headers
*
* asf: codec_data as specified in the ASF specification
* Simple/Main profile: 4 byte sequence header without startcode
* Advanced profile: Sequence header and entrypoint with startcodes
*
* sequence-layer: codec_data as specified in SMPTE 421M Annex L.2
*
*
* stream-format:
* bdu: BDUs with startcodes
*
* bdu-frame: BDUs with startcodes, everything up to and including a frame
* per buffer. This also means everything needed to decode a frame, i.e.
* field and slice BDUs
*
* sequence-layer-bdu: Sequence layer in first buffer, then BDUs with startcodes
*
* sequence-layer-bdu-frame: Sequence layer in first buffer, then only frame
* BDUs with startcodes, i.e. everything up to and including a frame.
*
* sequence-layer-raw-frame: Sequence layer in first buffer, then only frame
* BDUs without startcodes. Only for simple/main profile.

* sequence-layer-frame-layer: As specified in SMPTE 421M Annex L, sequence-layer
* first, then BDUs inside frame-layer
*
* asf: As specified in the ASF specification.
* For simple/main profile a single frame BDU without startcodes per buffer
* For advanced profile one or many BDUs with/without startcodes:
* Startcodes required if non-frame BDU or multiple BDUs per buffer
* unless frame BDU followed by field BDU. In that case only second (field)
* startcode required.
*
* frame-layer: As specified in SMPTE 421M Annex L.2

* If no stream-format is given in the caps we do the following:

vc1parse: implement asf to *-frame-layer stream-format This commit add an helper to convert a frame to frame-layer format and use it to implement these two stream-format conversion: - asf --> sequence-layer-frame-layer - asf --> frame-layer In simple/main profile, we basically have a raw frame, so building a frame layer isn't too complicated. But in advanced profile, the first frame-layer should contain sequence-header, entrypoint, and frame and each keyframe should contain entrypoint, so we have to handle these carefully. https://bugzilla.gnome.org/show_bug.cgi?id=738526

But in advanced profile, the first frame-layer should contain sequence-header, entrypoint, and frame and each keyframe should contain entrypoint, so we have to handle these carefully. https://bugzilla.gnome.org/show_bug.cgi?id=738526
