  ffmpeg adobe flash mp4 conversion problem

  Posted by Ofer Kruzel on September 21, 2011 at 7:37 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
