• Having trouble streaming video with FFmpeg over TCP on Windows [closed]

  8 mars 2024, par Tharunkumar Ampolu

  I'm trying to stream a video using FFmpeg over TCP on a Windows system. I'm using the following command

  


  ffmpeg -i video.mp4 -f mpegts tcp://192.168.24.3:2000?listen



  


  However, I encounter the following errors :

  


  Error opening output tcp ://192.168.24.3:2000 ?listen : Error number -10049 occurred
Error opening output file tcp ://192.168.24.3:2000 ?listen.
Error opening output files : Error number -10049 occurred

  


  I attempted to stream the video using the specified FFmpeg command.
I provided the command and the input file (video.mp4).
However, the command resulted in errors related to opening the output file for streaming.

  


  I expected the FFmpeg command to successfully stream the video over TCP to the specified address and port (192.168.24.3:2000).
I expected the command to run without errors and for the video stream to be accessible at the specified destination.

  


• Passing arguments to FFMPEG using subprocess.call()

  8 mai 2018, par Peter F

  I was working through this answer to an FFMPEG question and the command works just fine through the Windows 10 command prompt (I’ve only changed the input and output filenames) :

  ffmpeg -i test.mp4  -filter:v "select='gt(scene,0.4)',showinfo" -f null  - 2> test.txt

  My Python 3 script gives arguments (as a list) to the subprocess.call() function and works fine for a number of basic FFMPEG operations, but not this one ! It seems to be failing at the final null - 2> test.txt part, with the following error messages depending on how I split the arguments :

  [NULL @ 000001c7e556a3c0] [error] Unable to find a suitable output format for 'pipe:'
  
  [error] pipe:: Invalid argument
  
  
  
  [error] Unrecognized option '2> test.txt'.
  
  [fatal] Error splitting the argument list: Option not found
  
  
  
  [error] Unrecognized option '2>'.
  
  [fatal] Error splitting the argument list: Option not found

  Here’s the basic list of arguments I’ve been trying :

  args=['C:\\Program Files\\ffmpeg\\ffmpeg.exe',
  
        '-i',
  
        'test.mp4',
  
        '-filter:v "select=\'gt(scene,0.4)\',showinfo"',
  
        '-f null',
  
        '-',
  
        '2>',
  
        'test.txt']

  Plus various permutations combining and splitting the last few elements.

  Please could somebody help me with the right syntax for running FFMPEG with these arguments through Python 3 ?

  Many thanks - I just can’t see where I’m going wrong :(

• automatically convert all video to mp4 h264 [on hold]

  23 août 2013, par Xiabili

  I am a debian user and I have a lot of videos (wmv, flv, mp4 ... more than 100gb) on my server.

  The problem is that the most of these videos are with mpeg4 and these codec is not supported by our Wowza server (basic License).

  That is way we want to convert all these videos into H264 format.

  So I need a script that converts videos recursively in the folders and if possible remove the old files after the converting.

  I need your experience ! Thanks a lot !

  Regards
