Yes, as the previous results above, decoding cpu/gpu (before remap/after remap) But no speed benefit to set remap, results just within variations from time to time
You also can probably watch with top/conky/gkrellm if cpu usage goes down with qsv decoding case?
Does decoding heavier (hevc?) examples change the picture?
RPM Cinelerra Infinity - built: Mar 1 2026 06:30:41
khm, rpm does not have this patch .... so with or without remap it should be nearly the same? Strange it is not ...
What about my own last build, does it have the patch? Cinelerra Infinity - built: Mar 2 2026 22:23:36
Unless you partially rebuilt it with patch - no.
I thought you patched/rebuild it already ....
I'll do a rebuild from git now, then it should be ok with the patch? (I thought remap was a standard function because there already was a remap line in decode.opts)
