Converting HLG HDR Video to PQ HDR Video (HDR10)
and yeah, mercy be upon ye if you plan on trying to get libplacebo hardware accelerated via vulkan. That was painful, time consuming, and I failed. Maybe things have changed in the past two years, but I would really not want to try that again 😅

1080p decode with cuda hw accel is about 500fps
Cpu decode is 380fps
CPU decode + zscale about 200fps.
soo, Guess I'm wrong. Its probably zscale and copying shit all over the place that is the primary time sink

my guess is its CPU decoded, and thats whats slowing you down

huh.. That seems a bit slow. I know I'm not doing 2160p60, but I am curious what is taking so long 😛

not sure if you're on windows or linux, but opencl has hardware accel for tonemapping, which might work heh

instead of
clip, look into npl, tonemap filters, desat, peak
with tonemap, you might be interested in bt239029 replies

So, you're happy with this? Or do you want to tweak the output a bit? Looking for speedups?

Obs Clips
I don't have enough information about your setup, or the game, but I am going to make an educated guess.
I have a headset (and I think you do to) that splits comms and game into two seperate channels, and I have a wheel on my headset that can "tune" / balance these to "channels". Its really cool and convenient, and it also allows me to capture game and voice seperately (which is really convenient).
However, if in your software (for example OBS), you only add the "game " audio source, and not the "comms" audio source, then you get exactly what you are describing. You hear it in your headset (cus its always playing both), but the capture software does not, because it only has one of the "channels" / devices added.
You can go into either global audio (in settings), or just add the "comms" audio output device to your scene, and you'll get both (and you can balance, or even split between audio tracks).
So, assuming this is correct, then you are in an amazing position where you can easily mute or balance your game audio with the comms (nice to be able to mute or lower someone screaming or cursing without it impacting the game audioa 😄 )
Best of luck, hope that helps, and that my assumption is correct :OBSHeart:

OBS gets stuck on "Stoping Recording"
Stuff to rule out:
Disable hags, restart the computer, see if it still Happens.
Does it only happen on the d drive? Is it USB? Old spinning rust?
Are you using the splitting feature? (Split file ever x min / x size)

could also try

Seems there is no filler option for hevc_nvemc ffmpeg. I believe there is in avcodec, but appears to not be exposed

Setting the bufsize that high will make it less like CBR. Nvenc already fluctuates a fair amount, so I wouldn't set it any higher than equal to the bitrate. Unsure if you can use filler with the icecast protocol, but try enabling filler data if possible @Yasaka

Multi monitor OBS rendering issue
Make sure windows is up to date (if win10, older builds were suboptimal). Set the 144hz monitors to 120hz. That's all I can think of, unless there is some gsync wonk

Curious as to what options others are using in FFmpeg for av1_nvenc encoding.
Here is a decent example of how VBR-CQ will generate smaller files than CQP (when adjusted for avg QP), for me, on racing video game
-c:v hevc_nvenc -rc vbr -cq 24 -preset p7 -maxrate 240M -bufsize 480M
maxrate and bufsize is ridiclously high, cus I in essence don't want to be limited, and just want CQ to hit the quants it believes is good.
File is smaller than CQP, but visually comparable, as its cut some data in ranges where human don't really notice much (high frequency areas etc). It also seems to use a lower quant for areas that a bright and sharp (it deems important). Has overall lower accuracy, but that is to be expected, and if that is what you're after, then you should be using CQP anyway (this is not for accuracy)
Personally, I would definitely add inn AQ (For VBR-CQ) for even more savings (or quality gain) for human visual perception. It is up to you tho @ninbura18 replies
