• Subprocess not working when called in atom

  22 août 2019, par jan1892

  I am running python3.6 in Atom using the package ’script’ on Ubuntu 18.04.

  I am trying to cut videos using ffpb (basically ffmpeg with a progress bar instead of verbose).

  The following code gives the error : ’FileNotFoundError : [Errno 2] No such file or directory : ’ffpb’ : ’ffpb’

  import subprocess
  
  
  
  cmds = ['ffpb', '-i', 'input.mp4', 'output.mp4']
  
  subprocess.call(cmds)

  • The command ’ffpb -i input.mp4 output.mp4’ works in the terminal
  • The script works when I call it with python3 in the terminal
  • The script works in atom if I replace ffpb by ffmpeg
  • I installed ffpb using pip3 install —user ffpb
  • I never had problems like this running code in atom before.

  Thanks in advance for any help.

• linux ffmpeg Live streaming cannot connect to another PC

  9 juin 2019, par Tae-Yeong

  I’m set ffserver and ffmpeg streaming code in the linux console terminal.

  ffserver => ffserver -f ./ffserver.conf (terminal 1)

  ffmpeg => ffmpeg -r 15 -s 640x480 -f video4linux2 -i /dev/video0 http://mylocalhostip:8090/feed1.ffm (terminal 2)

  It was working success in the localhost.
  But It could not connect other PC or Mobile.
  Firewall set disable.

  My desktop and mobile have a normal Internet connection.

  I want to Live-Streaming connect other PC or Mobile.
  How can I do ?

  Hardware = LattePanda
  OS = Ubuntu 16.04

  < ffserver.conf >

  HTTPPort 8090

  bind to all IPs aliased or not

  HTTPBindAddress 0.0.0.0

  max number of simultaneous clients

  MaxClients 1000

  max bandwidth per-client (kb/s)

  MaxBandwidth 10000

  Suppress that if you want to launch ffserver as a daemon.

  NoDaemon

      <feed>
  
      File /tmp/feed1.ffm
  
      FileMaxSize 100M

  I expect to output of My WebCam Screen, but the actual output timeout.
