I have the doc/examples programs compiled and running. I use
the program demuxing.c to decode an AVI file. From the source
code, it looks it calls its own subroutine decode_packet() to decode
the next video or audio packet, and that subroutine calls
avcodec_ecode_video2()to decode the next frame. But they all decode
sequential frames. How can I decode an arbitrary frame in the
video stream?
You can use avformat_seek_file() followed by avcodec_flush_buffers()
before av_read_frame() to jump to an arbitrary position in the Stream.
