[FFmpeg-user] maintain avsync in rawvideo/rawaudio output even if input frame lost

[Jogh]

Hi all,


I have a flv/mp4 file which has some frame/packet lost. If I have to recode the video and audio inside this file into raw video and raw audio that both can't store timing infos. How should I duplicate from existing frames or generate blank frames to keep the recoded video and audio still synced in case I have to remux them in the further step.


Thanks,
Jogh
