Comment:
MediaCodec doesn't support global header, both mp4 and flv can handle
that, but mkv muxer doesn't.
There is already a workaround in mkv to support AV1 without global header:
{{{
case AV_CODEC_ID_AV1:
if (extradata_size)
return ff_isom_write_av1c(dyn_cp, extradata,
extradata_size, 1);
else
*size_to_reserve = (AV1_SANE_SEQUENCE_HEADER_MAX_BITS + 7) / 8
+ 100;
break;
}}}
We need to the same for H.264/H.265.
However, I'm wondering how to fix it in a generic way, instead of rework
in each format.
