AFAIK no, you have to skip the frames you aren't interested basing
this decision on the type of the packet or on the number of the
stream.
For example:
while (av_read_frame (format_ctx, &pkt) >= 0) {
/* drop non-video/audio frames */
if (pkt.stream_index != video_stream_nb || pkt.stream_index !=
audio_stream_nb)
continue;
...
}
