Repository for v4l2request hardware video decoding (rockchip, allwinner)

[BoringName]

I initially tried the instructions in the original post and it didn't work for me. On an allwinner h618 box with a mali-G31. I then spent pretty much all day today trying to find a fix. I came across a post on here stating the version of mpv that works with v4l2 needs to be compiled with the same package versions as ffmpeg or something along those lines. When I first tried the instructions I already had mpv installed and I remember it stating that it didn't update it.

 

So for a hail mary I ran apt remove ffmpeg and apt remove mpv. Then I ran the instructions again and noticed first one didn't actually run successfully which could have been why they didn't work this morning.... When I copy pasted into the terminal it left the $ signs in there and caused errors. So I manually typed it out and got everything to run successfully.

 

Now everything works. mpv is buttery smooth.

 

Previously mpv stated drm was unsupported now it says "using hardware decoding (drm)".

I had checked ffmpeg and it did list v4l2 as supported so maybe that didn't need to be reinstalled.

 

Anyway, if it hasn't worked for you maybe try uninstalling ffmpeg and mpv and running the commands again.

the problem is not ffmpeg, which already is works totally fine on debian Trixie (and backwards), the problem is within mpv that changed in v0.4.0 carried by debian Trixie,  and at the moment I don't have enough motivation to carry on a custom mpv package for Debian Trixie.

 

Thank you for the comment Jock

Yes, I know that Trixie's mpv made some changes that made it incompatible with your ffmpeg+v4lrequest package.

 

I tried to compile mpv, and I wasn't sure of how to do it.

I asked for help in the mpv github, and someone told me to wait for ffmpeg to merge this function.

Recently, I got more suggestions to build ffmpeg for Trixie  https://github.com/mpv-player/mpv/pull/14690#issuecomment-3828170966

 

Boringname... can you specify which Debian version, Linux kernel and graphical desktop (kde, xfce, gnome, plasma, labwc, sway)?

It's this image from @Nick A github.

I had to copy over a few firmware files to get wifi/bluetooth working but otherwise it's unchanged.
