i might look into packaging vlc, mpv and kodi build against the ffmpeg with omx patches, if nobody else does.

Oh sweet, nice job. I’ve been out of touch for a while. I started some similar PKGBUILDs months ago but didn’t have time to finish the project. Glad someone else stepped up :slight_smile:

pacman -S xf86-video-fbdev

The debian image is using mode setting for x11, not fbdev. Config is in /usr/local/etc

New release for mesa-pvr-vf2 Release v22.1.3-3 · cwt/aur-mesa-pvr-vf2 · GitHub.

As @sajattack tested and found a lot of segfaults from LLVM-15, the LLVM JIT was disabled in this release.

wave5 decoding via gstreamer v4l2h264dec somewhat works, but not fully stable. Got a kernel oops after 11% into the file.

gst-play can’t select a specific hardware decoder, so it needs a pipeline.

How do I install this? The github doesn’t mention anything, and sudo mv * /usr destroyed my system.

https://wiki.archlinux.org/title/Pacman#Additional_commands

Install a ‘local’ package that is not from a remote repository

pacman -U */path/to/package/package_name-version.pkg.tar.zst

ah thanks this helped. I didn’t realize that that file was the package and not some compressed archive.

New AUR build today. No obvious llvm dependencies I could see.

And WOW! A whole pile of Clutter / Cogl stuff that crashed big time previously, now works.

Yeah I tweaked the flags and removed some things the hardware didn’t seem to support and it seems to be working pretty good now. I’m still not totally sure whether glx should be enabled or not. Seems like KDE needs it but it also seems to make lots of things fall back to swrast. I’ll keep tinkering.

Also tweaked the retroarch package to support opengles

New kernel is released to fix the missing vdso files. So now you can build an external module using just the kernel headers package.

By the way, if you want to build the external module with non-root user, please add that user to group root first.

$ sudo usermod -a -G root <username>

And then logout and login again.

Thank you. I’m gonna try building colabora wave5 kmod again. Maybe it comes down to a few steps. It would still need the v42l patch though.

Should we unify compiler and compile flags across the builds?

Considering this very limited set of targets, the use of optimization flags is really an option.

https://github.com/archlinuxarm/PKGBUILDs/blob/master/README.md

Arch Linux ARM has some extra bitflag for specific targets.

I don’t understand what they are trying to do. Is that a place for all customized packages for ArchLinux ARM? I believe we have almost the same thing (or at least the same concept) at GitHub - felixonmars/archriscv-packages: Modified Arch Linux packages for archriscv.

They build images for a wide range of arm sbc with great docu as well

https://archlinuxarm.org/wiki/Raspberry_Pi

Given the similarities, it might be a useful resource to build upon.
