• test/test_compression.sh : Fix for OSX.

  test/test_compression.sh : Fix for OSX.
  On Mac OSX, the ’wc -c’ command returns a number with leading whitespace
  
  which then results in a syntax error when the shell parser expects a
  
  number when it really has a string containing a number. The easy fix is
  
  to use string interpolation.

• How do I make audio work with pulseaudio in systemd ? [migrated]

  1er avril 2022, par user5827693

  I'm trying to live stream my website to the rtmp server via pulseaudio, ffmpeg and chromium in ubuntu 20.04. Everything works great if I execute the following commands in shell :

  


  pulseaudio&
ffmpeg -y -f x11grab -draw_mouse 0 -s 1280x720 -i :1.0+0,0 -f pulse -ac 2 -i default -c:v libx264 -c:a aac -b:a 128k -f flv MY_SERVER &> /dev/null < /dev/null &
DISPLAY=:1.0 chromium-browser --autoplay-policy=no-user-gesture-required --disable-gpu --user-data-dir=/tmp/test --window-position=0,0 --window-size=1280,720 --app=MY_URL &


  


  However if I try to setup the same logic via systemd - everything works fine, except there is no audio. Below are my systemd files.

  


  pulseaudio.service

  


  [Unit]
Description=PulseAudio system server

[Service]
User=ubuntu
Type=notify
ExecStart=/usr/bin/pulseaudio --daemonize=no
Restart=always

[Install]
WantedBy=multi-user.target


  


  chromium.service

Description=start chromium browser

ExecStart=/usr/bin/chromium-browser --autoplay-policy=no-user-gesture-required --disable-gpu --user-data-dir=/tmp/test --window-position=0,0 --window-size=1280,720 --app=MY_URL
Restart=always

[Install]
WantedBy=multi-user.target


  


  ffmpeg.service

  


  [Unit]

[Service]

Restart=always

[Install]
WantedBy=multi-user.target


  


  I do not see any errors in my syslog regarding the audio. I can't figure out why it would work from shell but not from systemd.

  


  I tried the following :

  


  

  • Ran pulseaudio systemwide

  


  • Tried to setup systemd under root user

  


  • Tried to setup systemd under non root user

  


  • Tried all possible pulseaudio params
