[Libav-user] How to insert blank packet in a stream without re-encoding it

[William MANCON]

Hi,

Just want to know if it is possible (with the use of libav/ffmpeg API) to
insert in a stream "blank frame" without re-encoding it.
I have somme corrupted video (VP8 video). Some frames were lost or
corrupted during the transfert.
In order to keep audio & video sync I wanted to insert blank frame in the
case of video packet lost. (frame with no difference with the previous
one).

Thanks,
William.
