      avcodecmap: exclude avc3 stream format from AV_CODEC_ID_H264 · 61153a5a
      Alex Ashley authored and Sebastian Dröge's avatar Sebastian Dröge committed
      As part of the changes to support the "avc3" variant of the ISO-BMFF
      (see bug #702004) a new stream-format has been created
      (video/x-h264, stream-format="avc3", alignment="au") that requires
      changes to gstavcodecmap to exclude this format because avdec_h264
      expects the SPS and PPS to be in the codec_data.
      
      Amendment 2 of ISO/IEC 14496-15 (AVC file format) is defining a new
      structure for fragmented MP4 called "avc3". The principal difference
      between AVC1 and AVC3 is the location of the codec initialisation data
      (e.g. SPS, PPS). In AVC1 this data is placed in the initial MOOV box
      (moov.trak.mdia.minf.stbl.stsd.avc1) but in AVC3 this data goes in the
      first sample of every fragment.
