[FFmpeg-user] Solved! (was Re: Problem: some videos freeze, other very similar videos do not--difference might be just in resolution (pixels)--how to convert?)

[Randy Kramer]

I got the problem solved.  

It turns out it was related to the 1000 fps for the container. ("Seems stream 
0 codec frame rate differs from container frame rate: 1000.00...")

With various hints, some from these lists, I managed to get an ffmpeg command 
that converted the videos (well, I've only tested this on one so far):

ffmpeg -i video1.flv -vcodec libx264 -acodec copy -r 29.92 video1_h264.flv

With this conversion, the video starts playing promptly, I no longer see the 
reference to 1000 fps, and I haven't had any freezes (even while my machine 
is loaded enough that the original file does freeze).

The file does increase in size by about 25%.  I don't think the video 
deteriorates much if at all, but I've been staring at it too long.  I need to 
take a look at it with fresh eyes, maybe tomorrow.

(Other conversions that I tried, like to .avi format resulted in files about 
the same size, but noticeable deterioration in the video (and preserved the 
1000 fps, which seemed not to cause a problem (as a .avi) for mplayer.)

Thanks for the help!
