Test webcam using MPLAYER in Gentoo GNU/Linux

Published: Wed 13 May 2020

To be able be to use your webcam via mplayer on Gentoo you need to compile it with the v4l USE flag, for that you need to add the USE flag to the package.use:

# webcam mplayer
>=media-video/mplayer-1.3.0-r6 v4l

If mplayer is already installed you need to re-emerge it using with that new flag:

sudo emerge --changed-use -a media-video/mplayer

Now you can test your webcam:

mplayer tv:// -tv driver=v4l2:width=640:height=480:device=/dev/video0
