I did a few hevc and av1 OSV render tests using the latest RPM w/oneVPL on Leap, to compare it with my own AppImage. To get the AppImage from Slowroll to run om Leap, I had to add-install a newer version libFLAC12. The machine is AlderLake w/Arc A750 gpu The OS root drive is on a std SATA disc, while the video files are read/written to a fast M.2 disc. Results: hevc_qsv_8b420.mp4 ** rendered 5972 frames in 19.255 secs, 310.153 fps (RPM) ** rendered 5972 frames in 23.798 secs, 250.945 fps (AppImage) av1_qsv_8b420.mp4 ** rendered 5972 frames in 18.612 secs, 320.868 fps (RPM) ** rendered 5972 frames in 21.470 secs, 278.156 fps (AppImage) In average rendering is ca. 20% faster with the RPM. I did also additional test with the AppImage on Slowroll and got a bit faster rendering, but not so fast as with RPM on Leap.
