For those using HW that still uses the stateful V4L2 API for decoding - such as the #RaspberryPi4 - I uploaded another build to the link in the first post that includes a #GStreamer patch that is not close to landing, but works well enough to make playback work.

With that I can play 1080p30fps videos (the decoder limit) on my big screen smoothly, which otherwise not possible (apart from reducing the resolution).

#RaspberryPi #Wayland #gtk

The video shows a Gnome desktop running on a Raspberry Pi 4, using a screen with a resolution of 2560x1440 pixels. A 1080p@30fps video is played with the mentioned livi player build. While the video is choppy when the video overlay is visible, it becomes fully smooth once the overlay is hidden and zero-copy playback using the display controller hardware plane is used and the 3D engine can be skipped.
