[FFmpeg-devel] Repetition of previous frame after loss of current frame

To copy previous reference frame, there is a function in logavfilter->avfilter.c->avfilter_start_frame. Does anyone know about this function? Is there any frame copy or frame interpolation concealment available in ffmpeg for whole frame loss? Please let me know. Thanks.

Can anyone please tell me where to look if I want to repeat previous P frame after the drop of B frame. The sequence I am using is going to be in IPBPBPB format. So it should work for me.

In my experiment and with current ffmpeg decoder whenever I get one slice for one B frame depending on what slice size I specified, drop of that slice obviously shows the loss of that frame. Instead of missing one B frame I want to repeat previous P frame to get the same number of decoded frames as original. Can someone let me know how I can do this?  

Thanks,
Hardik
