:
The hardware acceleration of rx550 is limited to h264 and fullhd at 30fps.
you mean encoding? It can do 4k just slooowly .... (in cingg) Decoding 4k 10bit hevc works via vaapi/mpv (0.37 git) mplayer show fast green image via vdpau ;) On normal 8bit h264 mplayer's vdpau works ok, my display just 1440*900 but file itself can be FHD 60 fps (from YouTube).

Rx 550 is one of problem-free VGA card on Linux)). Free drivers are very stable. It still has enough power to run some 3d games, I run dagor engine demo 50+ fps with fullhd resolution.
Best regards, Andrey

So, mpv plays 4k HDR file from iPhone11 smoothly (finally!)
CinGG only can do 15 fps on this file :( (8bit RGBA project, x11 output)
Encoding into 8bit HEVC also work:

but encoding still was done in seven minutes for 20 seconds test clip (no tonemap either)
So I guess my machine seriosly bootlenecked by PCIe speeds/memory speeds?

Hm, 32 Gb/s should be enough for many 4k streams?
4k ~= 8Kpix, 8*60 = 480Mpix/sec 4 byte/per pixel (30 bit for 10 bpc colors, 2 padding) still just 2Gb/s! -- Cin mailing list [email protected] https://lists.cinelerra-gg.org/mailman/listinfo/cin
