  4 décembre 2015, par user650922

  This question already has an answer here :

  • FFmpeg : Error occurred while encoding audio stream from ac3 to aac
    
    1 answer
    

  As a testing purpose I am converting .mp4 video to .mp4.

  The error message is "Error while opening encoder for output stream #0:1 - maybe incorrect parameters such as bit_rate, rate, width or height".

  Could someone please help me in finding the reason behind below error.

  Below is my terminal log.

• Converting Video files in a Azure Webjob with ffMpeg

  13 décembre 2016, par Kevin Phifer

  I’m having trouble using ffMpeg in an Azure webjob.

  I found the following article (How to call ffmpeg.exe to convert audio files on Windows Azure ?) and it is exactly what I want to do, however, I cannot get ffMpeg to execute and it gives no error message.

  To diagnose the problem, I have boiled it down to its essentials by uploading ffMpeg, a video file to convert, and batch file to run it :

  

  The script in run.cmd is simply :

  del output.mp4
  
  ffmpeg -i screencast.wmv -c:v libx264 -r 15 output.mp4

  This works on my personal machine, but ran as a webjob I get results below.

  Edit :
  Additionally, it was suggested that I run using Kudu console. Still no luck :
  

  Solution :
  I ended up needing to run the 32 version of ffMpeg and not the 64 bit. Thanks so much @mathewc !
