I am recording H.264 (640×480 @1fps 10seconds) in avi container using FFMPEG. When I play the recorded file in VLC, it plays only first frame and rest of the frames are not played. I am getting
main warning: late picture skipped (555293 > -305)

Is there something I am doing wrong? Same code works perfectly for frame rate above 3
I am answering my question, It may help someone having similar issues:
VLC plays streams when I increase cache size from 300ms to 900ms. I am not sure if its a correct method or not. As avi header is having information of framerate, VLC should wait for atleast 900 or 1000ms for next frame. “late picture skipped” should come after 1000ms.
