Slow video in console-only

Hi,
Whenever I run my RPi 4B 4GB in console mode RPiPlay renders the feed really slowly. It keeps getting slower and slower like in issue https://github.com/FD-/RPiPlay/issues/265. However when I run it inside the Desktop GUI it performs fine.
At first I thought it might be the resolution and I was somewhat correct. With a 4K resolution in the GUI the feed performed similarly slow. Scaling the window down made it go faster. So I made the resolution smaller and running RPiPlay in fullscreen was fine.
I finally got the resolution down in the console but even at 1280x720 it would run as slow. I tried changing the assigned GPU memory so ARM would have 512mb and GPU 512mb as well, still no dice.
Lastly I also tried patching GStreamer using the guide provided from UxPlay https://github.com/FDH2/UxPlay/wiki/Gstreamer-Video4Linux2-plugin-patches
I'm running latest Bullseye Raspberry Pi OS, with all latest updates as of today. It was the same without the latest updates.
RPiPlay is installed through PiKiss.
What can I do? It seems to me like the console is missing some GPU-related resources. Only workaround I can think of is auto-running RPiPlay inside the GUI but I don't see an option to have the mirror window automatically enter fullscreen.
The UxPlay GStreamer patches provide 32-/64-bit Video4Linux2 support for the Pi, using the GStreamer plugin.
Unless something in it has recently changed, RPiPlay only uses 32-bit OpenMAX for non-GStreamer GPU support. (unfortunately OpenMAX is deprecated and no longer actively supported on RPi, so this has no long-term future). The Gstreamer option on RPiPlay will probably not work with Video4Linux2, since some tweaks to the video pipeline are needed. You should see if using UxPlay-1.53 instead of RPiPlay fixes your issue. Use uxplay -rpifb for use with KMS framebuffer, which I guess is what you mean by console mode, (no X11).
The UxPlay Video4Linux2 support is now working great on RPi 4B using development GStreamer-1.21, which is scheduled to be released as GStreamer-1.22 later this summer, and the UxPlay site has backport patches to GStreamer-18.4 and later available now, before the 1.22 release.
