• Running ffmpeg command from within python on windows

  15 octobre 2020, par Cheezy

  I am running python 3.8 on windows. I have a ffmpeg command that works within bash, but not within the command prompt. It gives me an error :

  


  


  No such filter : '[0:v]scale=ih16/9 :-1,boxblur=luma_radius=min(h,w)/20:luma_power=1:chroma_radius=min(cw,ch)/20:chroma_power=1[bg] ;[bg][0:v]overlay=(W-w)/2 :(H-h)/2,crop=h=iw9/16,scale=1920x1080'
Error initializing complex filters.
Invalid argument

  


  


  The command :

  


  ffmpeg -y -i input.mp4 -lavfi '[0:v]scale=ih*16/9:-1,boxblur=luma_radius=min(h\,w)/20:luma_power=1:chroma_radius=min(cw\,ch)/20:chroma_power=1[bg];[bg][0:v]overlay=(W-w)/2:(H-h)/2,crop=h=iw*9/16,scale=1920x1080' -vb 5m output.mp4


  


  I am trying to run this command from within python - I've tried with os.system() and subprocess.call(). It appears that it is using the windows shell instead of the terminal, as I'm getting the error message that I found on command prompt.

  


  How do I run bash commands from within python on windows ?

  


• ffmpeg command IP camera FishEye 360º [closed]

  28 octobre 2023, par Nuno Correia

  Using ffmpeg command to load the IP cameras streams I'm able to rotate the image with this command :

  


  ffmpeg:rtsp://admin:MyPassword@192.168.2.XXX:554/h264Preview_01_main#video=h264#rotate=90

  


  If I try to use the "filter" v360 I'm getting a error message and the stream doesn't occur with this command

  


  ffmpeg:rtsp://admin:MyPassword@192.168.2.XXX:554/h264Preview_01_main#video=h264#raw=-vf v360=fisheye:equirect:id_fov=360

  


  I also try to use this command without success also
ffmpeg:rtsp://admin:MyPassword@192.168.2.XXX:554/h264Preview_01_main#video=h264#raw=-vf

  


  The main idea is to use the ffmpeg commands to be able to view the modes "fisheye, dual panoramic view, quad view, cylindrical view" to use the different views available in the app but using the ffmepg command instead of the app.

  


  In the app I have the following option available View Modes available in the APP

    $dataPlay = [0 => $pid, 1 => $randomFolder];
    return $dataPlay;

public function stopCam($pid,$folder)
{
    shell_exec('kill '.$pid);
    shell_exec('pkill ffmpeg');
