• Losing video when splitting mpg from middle [migrated]

  12 avril 2014, par ARip1979

  Very new to ffmpeg so bear with me.

  I'm trying to split an mpg in two pieces. It's a 4m 36s video. I want the first piece to be 170s and the second to be the rest. I have tried a bunch of different methods.

  ffmpeg -i input.mpg -vcodec copy -acodec copy -ss 00:00:00 -t 00:2:50 output1.mpg
  
  ffmpeg -i input.mpg -vcodec copy -acodec copy -ss 00:02:50 output2.mpg
  
  
  
  ffmpeg -i input.mpg -t 170 -c copy output1.mpg -ss 170 -c copy output2.mpg

  And a bunch of others. Every thing I've tried gives me a great first output1.mpg but output2.mpg is always missing the video. The file is saved as .mpg but it is only audio.

  I found one option that said to try this for the 2nd piece.

  ffmpeg -ss 170 -i input.mpg -t 176 -c copy output2.mpg

  and that sometimes there are errors so to try :

  ffmpeg -ss 170 -i input.mpg -t 176 output2.mpg

  With the possibility that omitting '-c copy' might result in a good output.
  So the first one above with '-c copy' gave me the same result, no video. The second option resulted in video and audio but the video was severely degraded in quality.

  Can anyone help me ? Why do I keep losing the video on the 2nd piece. I'm a newb but this seems pretty straight forward.

  Thanks in advance !

  Une seule mise à jour vers la version 3.6.18 de FF suffit à régler le pb. Je ne connais pas les stats navigateur de la galaxie SPIP mais il n’est peut être pas utile de s’embêter pour si peu du coup...
