• FFMpeg is dropping video track when clipping an mpg video

  16 juin 2017, par M. Grishaber

  I am extracting a clip from an mpg video using the following command.
  ffmpeg.exe -i 271b.mpg -ss 00:00:05.000 -t 00:00:03.200 -c copy out_271b.mpg

  I am using the copy parameter to avoid reencoding the clip.
  The resulting mpg file only has the audio track, no video.
  The following is the FFMpeg screen dump.

  C:\ffmpeg-20170615\bin>ffmpeg.exe -i 271b.mpg -ss 00:00:05.000 -t 00:00:03.200 -c copy out_271b.mpg

  Addition : I tried to open the generated clip file with ffplay and got the following results. Note that ffplay was able to open and play the original mpg file.

• Video Created By FFMPEG is Blank [on hold]

  11 octobre 2015, par Larry Holze

  New to FFMPEG and trying to use it very simplistically. I have a sequence of images that I want to make into a video. Using this command :

  ffmpeg -framerate 30 -i "fr_%05d.jpg" out.mp4

  Creates the out.mp4 file OK, but when I play it back it is just blank.
  Pictures in the .jpg sequence are definitely not blank.

  Am I missing some option(s) ?

  Is there any way to execute it faster ? Or maybe I have to use gpu to proceed it faster ? Any ideas ? I execute it very often and any shortening time would be great.

  


  I read about hardware acceleration, but I am not sure if it will help. It is possible also to upgrade version of ffpmeg, but will it help ?
