• 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

• ffmpeg command never work in lambda function using nodejs [closed]

  4 décembre 2022, par Santosh swain

  I am trying to implement FFmpeg video streaming functionality such as Instagram countdown functionality. In this code, first of all, I get records(URLs) from the s3 bucket and then split them according to my need, and then create the command and execute it with exec() belonging to childe_process. in this, I am trying to store the out in some specific folder in lambda function but it was never stored. I thought lambda does allow to write files locally so I am trying to do the direct upload on the s3 bucket by using the stdout parameter of exec()'s callback. guys, please help to do that. I have a question lambda does allow to write content in its local folder ? or if not allow then whats the way to do that thing ? I just share my code please guide me.

• Revision 7b756183aa : Fix to source scaling for dynamic_resize. The fast scaling for 1 pass mode was

  Fix to source scaling for dynamic_resize.

  The fast scaling for 1 pass mode was being used only on the
  first frame after resizing event (because resize_scale_num/den
  is set to 1 and only changed for first frame following resize event).
