Mpv no work in Rock Pi 4Cplus

#1

Hello,

I just bought a Rock Pi 4Cplus and I have put the official Debian image with XFCE ([https://github.com/radxa/debos-radxa/releases/download/20221111-1029/rock-5a-debian-bullseye-xfce4-arm64-20221111-1344-gpt.img.xz]) on it and it shows me the following information:

Video is working, audible, but can’t seem to start graphical context.

The documentation on the RXDA website is outdated (https://wiki.radxa.com/Rock4/Debian) and supposedly the graphic drivers that make it work are already in the image.

Somebody can help me?

Regards

Hi, firstly I don’t why did you flash system for Rock 5A and then run on Rock Pi 4 C+.
Is it that download link correct?

Secondly recently I tried Armbian system on Rock Pi 4a and was able to play videos on it. Even mpv player should run faster I tried vlc and then I would try Kodi.

I’m sorry… Yes, it’s a wrong link. The correct image was:https://github.com/radxa/debos-radxa/releases/download/20221111-1029/rock-4c-plus-debian-bullseye-xfce4-arm64-20221028-1344-gpt.img.xz

Have you tried vlc ?

Hi again,

The tests I have done with VLC tell me that the player does not load the correct drivers with video acceleration from the Mali chip and that is why a 1080p video looks slightly slow and a 2160p video with audio delayed more than 5 seconds and the video having flickering:

Example of 1080p video:

were you able to fix this ?

Yeah I’m hanging for a fix too.

Need VLC playing RTSP stream, so used Flatpak, but whether compiled locally or using the pack it appears to be an issue!
