• python ff-mpeg not working on VM

  2 août 2013, par Bob

  I have two Windows 2008 R2 64 bit servers with two different host providers (GoDaddy and company B). My python script runs successfully on GoDaddy's server. It doesn't run successfully on the server with company B.

  I installed the same software on both servers :

  • Python 2.7 for Windows 32 bit
  • NumPY module
  • SetupTools
  • EchoNest API for Windows

  The company B server is giving me an error related to an executable called en-ffmpeg.exe that uses the python ff-mpeg module. The exact error message is

  [dv @ 0x1449690]Can't determine profile of DV input stream.
  C :\Music\song1.mp3 : Error while opening file

  The song.mp3 file exists. I installed the latest Windows updates on the server with Company B but still I get the error. I believe the error is because something is not configured properly on this server (missing libraries or drivers ?). However, I don't know what that is !

  Please help :)

  UPDATED TO INCLUDE COMMAND AND ERROR OUTPUT FROM FFMPEG

  COMMAND :

  c :\Python27>en-ffmpeg -i "C :\Music\song1.mp3" -y -ac 2 -ar 44100

• why ffmpeg is not working in new installation

  3 août 2013, par Hitesh Gupta

  I was working on live encoding from FFmpeg from last few days. One day I re-installed my OS and tried to run FFmpeg commands again after configuration. My publish points get in starting but could not started. Why ? Am I missing any configuration required ?

  The command I am trying to run is :

  ffmpeg -y -re -i D:\video2.mp4 -pix_fmt yuv420p -movflags isml+frag_keyframe -f ismv -threads 0 -c:v libx264 -preset fast -profile:v baseline -map 0:v -b:v:0 800k http://localhost/PPS/PublishPoint.isml/Streams(Encode
  
  r1)

  Output what I got in command prompt is :
