• ffmpeg generates file with only audio from ts

  8 novembre 2016, par Seoman

  I’m trying to get some parts of a ts video and then merge them into a new video. The problem is that when doing the split, the video is lost. The splits only contains audio. Here is the video source information :

  ffmpeg -i source_file.ts

  This is the command used for doing the split :

  ffmpeg -ss 10 -i source_file.ts -t 5 -c copy cut1.ts

  And this is the video information after the cut :

  If I reproduce cut1.ts I can only hear the audio. Video is gone.

• FFMPEG command not working on Ubuntu

  7 novembre 2016, par brijesh kumar

  I stuck with the command "anequalizer" in ffmpeg. I’m following the official documantation. It has example command in documentation like this

  anequalizer=c0 f=200 w=100 g=-10 t=1|c1 f=200 w=100 g=-10 t=1

  and when I run the command

  ffmpeg /home/overtatech-1/Music/jeena.mp3 -af "anequalizer=c0 f=200 w=100 g=-10 t=1|c1 f=200 w=100 g=-10 t=1" /home/overtatech-1/Music/jeena_new.mp3

  on console, I get error "c1:Command not found"

  Lenovo-G50-80:~$ ffmpeg /home/overtatech-1/Music/jeena.mp3 -af  "anequalizer=c0 f=200 w=100 g=-10 t=1|c1 f=200 w=100 g=-10 t=1" /home/overtatech-1/Music/jeena_new.mp3
