Hello,
I know it is using the PTS of the frame to seek to frames.
I want to perform a 'Step Forwards/Backwards' operation in my player, but the
problem is that the seeking to frames are not always working as I expected.
int64_t time_stamp = 0;
time_stamp = current_pts - frame_span; // frame_span is calculated by
avg_frame_rate, and in stream time base
search_flag = AVSEEK_FLAG_BACKWARD;
int ok = av_seek_frame(format_ctx, video_stream, times_tamp, search_flag);
The result would sometimes either jump to the current key frame or several key
frames earlier. What should I do to fix it?
By the way, is there any convenient way to know the index of the frame, which
is now playing?
Best Regards.
