[Libav-user] One frame video

[Yuriy Pryyma]

Good time of day

I'm writing program that creates long videos("mp4 container") that show 
only one frame for all time.
The idea is to write only one AVPacket that will be played for all 
time(seting pkt.pts, pkt.duration).
The problem is that video is very short after that(this does not work).
Should I put also one AVPacket in the end? Is it valid idea? How this 
could be implemented base on muxing.c

Thank you in advance
