• ffmpeg faild when processing video from stream

  17 octobre 2019, par Milousel

  I create ffmpeg method for modify video from readstream as input. I test it on videos which I download from internet and it’s works good. When I tried it on video from my phone it crash. I tried to modify (take off few second) video from internet and try it again, but I receive the same error message.

   an error happened: ffmpeg exited with code 1: pipe:0: Invalid data found when processing input
  
  Cannot determine format of input stream 0:0 after EOF
  
  Error marking filters as finished
  
  Conversion failed!

• Are there differences between the parameters of different versions of ffmpeg ?

  13 octobre 2019, par Mauro Alejandro Pereira

  I want to obtain a different raw video for each frame of an MP4 file.
  My instruction works in an old version of ffmpeg but not in the new one.

  In the mp4 file there are 137 frames. It is checked. The versions are installed on different machines.

  Versions 2.8.15 :

  $ ffmpeg -i ./video.mp4 -vf fps=30 -vframes 137 -vcodec rawvideo -s '1920x1080' -pix_fmt gray -threads 0 frame%08d.raw

• Join a lot of frames with some audio files

  30 octobre 2019, par Laurin Neff

  What I’m trying to do

  I have 3697 frames (frames/[0-3696].png) and 5 audio files, which are the same length in total as the resulting video should be (audio/[0-4].mp3). I’m trying to play the frames at 15 fps, with the audio files playing in sequence and putting this into out.mp4. How can I achieve this ?

  File tree

  What I’ve tried

  ffmpeg -i frames/%d.png -i audio/%d.mp3 -vf fps=15 out.mp4

  What I expect

  I expect out.mp4 to contain all frames, with the 5 mp3 files playing in sequence

  What actually happens

  $ ffmpeg -i frames/%d.png -i audio/%d.mp3 -vf fps=15 out.mp4
