ffmpeg adobe flash mp4 conversion problem
on Sep 21, 2011 at 7:37:20 am

Hi,
I'm using ffmpeg to convert flash player created h.264 file to ffmpeg format.
Its part of a larger functionality.

problem
-------
I'm running the following command:
ffmpeg -i 'host.mp4' -y -an -vcodec libx264 -b 1200k -r 25 -threads 0 -y 'singlevideoconvert.ts'

the original file is ~6 sec long.

after conversion, when plating, for example with ffplay, video playback is freeze for about 6 sec, then start playing, and after another 6 sec video freezes again, but ffplay seems to keep going

more info
---------
ffmpeg wrongly reports duration of 20 sec
Mp4Box says it ~6 sec, which is correct.

I can provide files and logs.

help welcomed.

Ofer
