vc1parse: parse frame header when stream format is ASF/raw for simple/main profile (2.66 KB, patch)
2014-10-14 11:31 UTC, Aurélien Zanelli 		committed Details | Review

Description Aurélien Zanelli 2014-10-14 11:28:42 UTC 
Currently, if we are in ASF/sequence-layer-raw-frame, we don't parse the frame header in simple/main case. Since we basically have raw frames in these profil, we can easily implement it and extract some information like the keyframe flag.

This will be useful for implementing some stream-format conversions.

    vc1parse: parse frame header when stream format is ASF/raw for simple/main profile
    
    When stream-format is ASF or sequence-layer-raw-frame, we basically have
    a raw frame so we can parse it to extract some information such the
    keyframe flag. The only requirement is to have a valid sequence-header.
    
    This commit parse the frame header and set the DELTA_UNIT buffer flag in
    case the frame is not a keyframe.
