And it is exactly what we are doing when we let users access fields
directly.
I mean:
AVStream **streams = ctx->streams;
av_read_frame(ctx, &packet);
AVStream *stream = streams[packet.stream_index];
That should work, right?
No, avformat_new_stream() will reallocate that array, so if
av_read_frame() can allocate new streams (I think AVFMT_NOHEADER formats
do that) then that may just crash.
You should always use ctx->streams directly.
