[libav-devel] [PATCH 3/6] movenc: enable Annex B to MP4 conversion for HEVC tracks.

--- Note: this includes a facility for filtering parameter set NALUs from the bitstream and knowing whether any NALUs were extracted (so that we can e.g. decide whether to generate a new MP4 sample entry with a new hvcC). It's unused as I'm not sure how the MP4 side of things would work.

[libav-devel] [PATCH 1/6] movenc: use 'hev1' tag for HEVC in MODE_MOV.

'hvc1' requires that parameter set NAL units be present only in the samples entry, but not in the samples themselves, requiring that additional parameter sets, if present, be filtered out of the samples and placed in new, additional sample entries if they override or otherwise conflict with the
