Doses OSMC support the Raspberry pi 4? If so, how does video playback preform? If not, how long until it is supported?
Not yet, but support will be added ‘soon’.
Software decoding will be possible after the release, so this will be limited to 1080p.
More details are on the blog.
I’m optimistic they will do better than that. I prefer OSMC, but the alpha release of LibreELEC has very impressive hardware support on the Pi4 already.
Test files: http://jell.yfish.us/
jellyfish-90-mbps-hd-hevc-10bit plays perfectly, no dropped frames. Low CPU.
jellyfish-120-mbps-4k-uhd-hevc-10bit looks very good but some dropped frames. Still low CPU.
jellyfish-120-mbps-4k-uhd-h264 plays far worse than the hevc-10bit version for some reason. Call it alpha issues probably.
Pi4 doesn’t support H264 above 1080p which is why the last jellyfish clip does not work well.
We will introduce hardware acceleration with Kodi v19 (and nightlies) with V4L2/GBM. The HW method currently used by LE is a stopgap and deprecated. It will shortly be removed as a video acceleration pathway from Kodi.
I have explained this in detail in the blog post
