besides as his problem seems to be with the output file, the issue
must be on th muxer/encoder side. the parsers are on the other side :)
I think maybe something like mistakely using the packet from
av_read_frame() for av_interleaved_write_frame() or so could
lead to such problem.
or maybe not setting the from encode buf/size in the AVPacket used for
of course it could be something else too
