So by the time you get there the channels are already validated.
the extradata is validated on container and codec level so it should
be fine.
This validation just makes sure that the codec can't be opened. But then
avformat_find_stream_info continues with reading a frame from the
demuxer, leading to the segfault if avctx->channels is 0.
do you have a sample for it?
Yes. You can create one by setting the 8th byte of an adx file to 0.
Best regards,
Andreas
