  FFMPEG dropping all frames.

  Posted by Kanishk Dudeja on July 17, 2014 at 8:14 am

  I have a raw H264 video which i am trying to convert into MP4 by the command:

  ffmpeg -i ‘Camera 4(172.16.2.12_554)_1_2014_07_16_15_20_08.h264’ ‘Camera
  4(172.16.2.12_554)_1_2014_07_16_15_20_08.mp4’

  FFMPEG keeps dropping all frames. Not even 1 frame is encoded.

  Please see the output below:

  Seems stream 0 codec frame rate differs from container frame rate:
  2400000.00 (2400000/1) -> 24.00 (24/1)
  Input #0, h264, from ‘Camera 4(172.16.2.12_554)_1_2014_07_16_15_20_08.h264’:
