• ffmpeg windows av_interleaved_write_frame() : Operation not permitted failure

  26 janvier 2021, par Purgoufr

  I'm trying to share my computer's camera with the remote computer. Local machine is linux(ubuntu 20.04.1) and remote machine is windows 10. I created virtual camera in windows machine with use OBS virtual cam and I want to share camera from local to remote machine. I could start stream from local linux machine and I got stream via windows machine. But when I try to write the stream into the virtual camera(output device), I get the error av_interleaved_write_frame (): Operation not permitted.

  


  The command I wrote on the Windows side is as follows :

  


  ffmpeg.exe -f mpegts -i udp://192.168.5.5:5010 -c:v rawvideo -r 30 -pix_fmt yuyv422 -s 1280x720 -f sdl "OBS-Camera"


  


  The error message is as follows :


  


  Extra Info1 : In my experiments, if both the local and remote machines are Linux, it works successfully.

  


  Extra Info2 : I can view the stream that I received on windows side(remote) with the command ffplay.exe udp: //192.168.5.5: 5010.

  


  Do you have any suggestion ?

  I'm trying to record selenium test run with FFMPEG, for automation testing of web extensions (selenium+js/ts).
FFMPEG initiated by command :

  


      const { spawn } = require("child_process");
        ffmpeg = spawn("ffmpeg", [
          "-x265-params",
          "-f",
          "xcbgrab", 
          "-video_size",
          "1280x1024", 
          "-i",
          process.env.DISPLAY, // "/private/tmp/com.apple.launchd.ID/org.macosforge.xquartz:0"
          "-loglevel",
          "debug", 
          "-y", 
          "-pix_fmt",
          "yuv420p",
          videoPath, 
        ]);


  


  Return constantly error,related to process.DISPLAY, I'm not sure why it's so :

  


      ffmpeg stderr: /private/tmp/com.apple.launchd.W851FkeNXz/org.macosforge.xquartz:0: Operation not supported on socket
