Hello all,
I've developed a video player based on libav and I've come across an
issue with seeking operations. I've coded the player pretty much like
the tutorial available on http://dranger.com/ffmpeg
What happens is that after an av_seek_frame() call and the corresponding
avcodec_flush_buffers(), the next ~10 frames cannot be decoded by
avcodec_decode_video2(). In fact the parameter "int *got_picture_ptr"
returns false in those cases. This introduces an ugly slow down on the
FPS rate until new video frames replace the undecoded ones in the queue.
If I don't call avcodec_flush_buffers() after the seek operation, all
frames are decoded but visual artifacts appear.
The video is an MPEG-TS file, codecs are mpeg2video and mp2. Can you
shed some light on what I should look for?
Regards,
Julian
