Smallish steps. A first official info-beamer pi for the Pi4 prerelease is now available on the info-beamer pi download page. A few things that don’t work right now:
- GL videos (those that you can scale/rotate/transform arbitrarily) are still not possible.
- I’m still now sure how all the 4K stuff and targeting multiple monitors work.
- There’s some screen tearing (see this example picture) going on. Not sure why.
- Some GL operations are slower on the Pi4. My guess is that the new GL driver is still rather untested and there’s a lot that will improve in the future.
- No 4K/H265 video support.
Documentation on all of that (e.g. linux DRM/GBM/mmal/how to play H265) is utter garbage, so it’s continuing to be a slow progress due to a lot of trial and error and waiting on more usable example code or documentation. It’s all quite frustrating.
A new info-beamer hosted OS using buster and this new info-beamer pi release will eventually be available for testing. Don’t expect that to be usable in any kind of production environment for a while though. The recommendation to use the battle tested Pi3 still stands
