Using MPlayer in Qt5

Question

I have a problem with default QtMultimedia backend GStreamer on my BeagleBone Black machine. When I am playing video over GStreamer it has a lot frame drops, and video is very slow. Behavior is the same when I play video over gstreamer command gst-launch-1.0 /home/debian/Desktop/video.mp4 .

Its not the case with MPlayer and video playback, everything works perfect, so I would like to use MPlayer instead of GStreamer in my Qt application for video playback, where to start with this implementation?

Answer 1

First of all: 'apt-get install mplayer'... i really never used mplayer for video, but for audio it's quite simple, and i guess it should follow the logic... to play audio with mplayer, use this:

mplayer -ao alsa -volume <'volumeInt'> <'file'>

Where:

<'volumeInt'> - values between 0 - 100;

<'arquivo'> - Target file.

To run in background, add the parameters (without simple quotes on path): <'/dev/null' >/dev/null 2>&1 &
