so nearly 10 fps with scaled to FHD input! (otherwise 32bit

==================
I admit I'm not sure what's going on in every detail above
and below. But I've tried to adapt something similar or
equivalent (?) using my Google Pixel 7 Pro smartphone to
record a small HDR10 video clip, and then using ffmpeg on my
Intel Alder Lake cpu/DG2 gpu workstation. Comments are
welcome for correction and learning?
Well, 125 fps sounds fast ;)
This line tries to convert HDR video to SDR version, same size
(for your case) but it now 10bit h264 instead of 10bit h265.
You probably can add format=yuv420p before all other -vf
liblacebo options so resulting file will be more compatible 8bit
h264.
You can try to watch both vids side by side, I think mpv uses
same algorithm as libplacebo, so on SDR screen results must look
close to each other?
I tried also to convert adding -vf format=yuv420p,
sorry, I mean
-i ~/K38_sdcard1/Documents/iPhone11_4K-recorder_59.940HDR10.mov -vf
libplacebo=format=yuv444p:w=1920:h=1080:force_original_aspect_ratio=decrease:normalize_sar=true:upscaler=ewa_lanczos:downscaler=ewa_lanczos:colorspace=bt709:color_primaries=bt709:color_trc=bt709:range=tv
format as part of -vf libplacebo string, not separate ffmpeg filter.
but both the 10bit and 8bit output files are distorted when
playback with vlc, mpv or ffplay.
In comparison testing with my highest ProRes hq 10bit video file
as input (not HDR), the output mp4 file looks fine with the same
ffmpeg code line.
Was there a download site with small HDR10 test clips available,
so we can test and compare using the same input?
No clips themselves, but wiki with links to them
https://kodi.wiki/view/Samples
I used
Apple "special" clip
"HDR10 HEVC 59.94 (MOV, @hdmkv's iPhone 11 Pro Max raw 4K footage
using 4K HDR Video Recorder app)"
https://drive.google.com/file/d/1Ic9DZXMSo07EJMqCFaQRKSSrSw6y1mYv/view?usp=sharing
================
For some reasons, the conversions work fine when I leave out the export
of environment variables:
env | egrep -i "ANV|vulkan"
