Thanks. I have many videos that behave better now. Unfortunately one of
them crashes after the first seek.
Here is the code I use when seeking:
av_seek_frame(fctx, pkt.stream_index, offset, AVSEEK_FLAG_BACKWARD);
avcodec_flush_buffers(pcodec);
The offset is correct as it was working fine before and seek around the
correct point. I've tried using -1 instead of pkt.stream_index but it
does the same.
I can't reproduce the crash when using the FFMPEG command-line as it
doesn't perform such seeking and FFPlay doesn't play anything.
I'm uploading a sample here (20,000KB):
