• FFmpeg-split.py can't determine video length

  13 juin 2017, par Almog Woldenberg

  First, I’m not a developer. I’m trying to split a movie into 1 minute clips usinf ffmpeg-split.py python script. I made sure FFmpeg is installed it trying a simple command and it worked like magic :

  ffmpeg -i soccer.mp4 -ss 00:00:00 -codec copy -t 10 soccer1.mp4

  A new video file was created in the same folder.

  I saved the FFmpeg-split.py in the same dir, updated python PATH and typed the following command :

  python ffmpeg-split.py -f soccer.mp4 -s 10

  what I got back was :

  can't determine video length

  I believe it just can’t find the file. I switched video files and even deleted it and got the same message.

  Any ideas ?

• Is there a Heroku-supported method for getting the length of an audio file in seconds ?

  I'm trying to implement

  But I'm unsure what gem provided FFMpegWrapper, and I'd like to use Heroku to deploy my app for testing. Does heroku support something that will work for this ?
