av_read_frame failed after av_seek_frame(0) called

[hxuanyu]

I built a test program with latest ffmpeg git header

the test code calls av_seek_frame(0) when av_read_frame returns < 0; while seek succeeded, all subsequent call to av_read_frame failed.

while this failed with latest ffmpeg it succeeded with ffmpeg-2.0.1

while (av_read_frame(pFormatCtx, &pkt) >= 0) {

printf("packet %d\n", count++);

}

ret = av_seek_frame(pFormatCtx, video_stream_idx, 0, AVSEEK_FLAG_BACKWARD);
if (ret < 0) {

printf("seek to 0 failed\n");
return 0;

} else { printf("seek ok\n"); }

av_init_packet(&pkt);
ret = av_read_frame(pFormatCtx, &pkt);
if (ret < 0) {

printf("read after seek failed *\n");

} else {

printf("read ok after seek(0)\n");

}
