To help you get started mpv provides sample configuration files with default settings.

User specific configuration is suggested since it may require some trial and error. Note: Configuration files are read system-wide from /etc/mpv and per-user from ~/.config/mpv (unless the environment variable XDG_CONFIG_HOME is set), where per-user settings override system-wide settings, all of which are overridden by the command line. To do this one only needs to create a few configuration files (they do not exist by default). However, if you have a computer with a more modern video card then mpv allows you to do a great deal of configuration to achieve better video quality (limited only by the power of your video card). Mpv comes with good all-around defaults that should work well on computers with weaker/older video cards. See List of applications/Multimedia#mpv-based.

Install the mpv package or mpv-git AUR for the development version.
By default ffmpegĪttempts to read the input(s) as fast as possible. Streams (where it can cause packet loss).
Should not be used with actual grab devices or live input Mainly used to simulate a grabĭevice, or live input stream (e.g. The video is received by: ffmpeg -i udp://localhost:50000 -f mpegts video.tsįurthermore, if your purpose is simply to simulate a live camera (as for testing a computer vision pipeline), you could use the native frame rate -re option, the looping -stream_loop -1 option and a static file: VIDE0=./static-video.mp4įfmpeg -re -stream_loop -1 -i $VIDEO -map 0:v -f mpegts udp://localhost:50000 For example: # (make sure you use the correct screen number, in my case it was :1, not :0)įfmpeg -re -f x11grab -r 15 -s 1280x720 -i :0.0+0,0 -map 0:v -c:v libx264 -f mpegts udp://localhost:50000 o - | mplayer -vf scale=480:360 -vo yuv4mpeg:file=/tmp/pipeĭid not test the last one, because you did not tell how your ffmpeg command look like.Īnother way to simulate a real world live camera is to use udp://. yuv4mpeg_to_v4l2 < /tmp/pipe &įfmpeg -someOptions. And in front of mplayer your ffmpeg command redirecting its output to stdout. Instead of the $TS you could put a - (which stands for stdin). Mplayer $TS -vf scale=480:360 -vo yuv4mpeg:file=/tmp/pipe MPlayer is able to play any webstreams, all kind of video files, even from stdin! I just tested it with a file from which is a german news site.
And replace /dev/video0 with your loopback device. Where you replace movie.mp4 with the name of your video file. Mplayer movie.mp4 -vf scale=480:360 -vo yuv4mpeg:file=/tmp/pipe Then run it from the examples directory like this: mkfifo /tmp/pipe # only needed once, as long as you do not delete the file /tmp/pipe Then change one line in the file examples/yuv4mpeg_to_v4l2.c of the v4l2loopback source folder from v. = V4L2_PIX_FMT_YUV420 Load the module with su -c 'modprobe v4l2loopback', Compile it ( make and su -c 'make install'),
