Two simple tests I got working Cinelerra Infinity - built: Sep  8 2024 10:37:25 (rpm installation)
on Leap 15.6 on i7-12700KF + Arc A750 gpu

As seen below, quite fast rendering:

  • 125 fps for proreshq.mov  (yuv422p10le) -> yuvj420p (10-bit  to 8-bit color depth)

I think due to some strangeness with full (pc, jpeg) data levels currently under investigation  you better to retry with color range set to MPEG?


Yeah, thanks. I changed Settings>Prefs>Appearance Color Range to MPEG, and the ffprobe output color range looks more in accordance with the input: yuv420p(tv, bt709 ....)

2)
ffprobe -hide_banner hd01_hevc_vaapi.mp4

But still  yuv422p10le input is changed automatic to  yuv420p output.
Actually in Cingg there is only one single preset "hevc_vaapi.mp4" available to select.

yeah, if my understanding of our code is correct vaapi encoding (and may be decoding, too?) limited to yuv420p. I'll look at OBS source to see if this can be easily fixed, but again, I have in HW to test .....

For now for hevc10 hw encode I can only suggest to create fifo file with mkfifo and point ffmpeg/y4m renderer to it (select supported pixformat from dropbox there). From second terminal run system's ffmpeg set up for hevc10 encode (via any method available).

You can start with 1 sec long test sequences in y4m as normal files just for initial finding of right ffmpeg command line.

You also in theory can setup something like v408 mov (qt) with pcm audio and faststart flag, and use this as on the fly lossless transport between cingg and ffmpeg, but I personally not tested that.





By showing information from the VA-API driver:
  • VLD means the card is capable to decode this format
  • Enc means it can encode this format.

I also did a short attempt with the Cingg Appimage, but as I think has been said before: HWA want work there.
