> blu-ray 4K
there's no simple answer to this

I personally would prefer single new Ryzen 2700X over used 20 cores server monster...
а оно мешает? нажать ignore
потом если сам SVPManager не будет запускаться, то смотреть что не так в консоли...
> The SVP index wasn't high enough for profile settings 1 and 3?
for playing in mpv - yes
> would 4k h.265 8-bit video use up the same amount of CPU to interpolate as 4k h.265 10-bit video?
nope, considering you're using hardware decoder, h.265 8-bit need the same CPU power as h.264 8-bit
HT gives wrong CPU load numbers. "50% CPU load with HT in Task Manager" can mean anything from real 50% to actual 100%.
My CPU shows 45% load with HT and 90% w/o HT with the same settings. But it doesn't mean "HT gives x2 performance boost".
зависит от того, можно ли влепить на XP VC++ 2017
я не знаю, не смотрел...

следующий на очереди - Avisynth+

Ryzen 7 8-cores, MPC-HC 64-bit - SVP @4K CPU load is less than 30%
at highest "auto" settings (and Ryzen 7 at 3.4 GHz loaded up to 50% in this mode)
Actualy, these are not entirely true 
CPU load numbers are half-fake because of hyper-threading turned on.
Here's one more attempt, with Ryzen 8-cores at 3.4 GHz and HT off:
"lvl" = SVP "auto" profile level, 1 is highest settings.
lvl / MPC-HC / mpv
4K H.264 (8-bit)
1 / 90% / 100%, SVP index < 0.9
3 / 70% / 85%
5 / 60% / 70%
4K H.265/HDR (10-bit) -> 8-bit
5 / 60% / 85%
4K H.265/HDR (10-bit) -> 10-bit
Is not supported in MPC-HC, and is not playable in mpv - 60% CPU load while SVP index stays below 0.8.
1. mpv needs more CPU power (~by 20%) for 4K playback than MPC-HC
2. 10-bit 4K is a no-go in current mpv version - something is limiting performance very badly
===
For 1080p 10-bit HDR difference is not so huge.
MPC-HC (8-bit) - 25% CPU load
mpv (8-bit) - 27%
mpv (10-bit) - 34%
BTW, 10-bit mode in SVP is kind of broken - intermediate frames are rounded to 8-bit and colors are incorrect. Will be fixed ASAP.
and the version of mediainfo package is...?
segfault in libmediainfo.so
never seen this before
try to update it to some newer version (if any)
> SVP @4K CPU load is less than 30%
let's say "50%" (at the highest "auto" settings and Ryzen 8-cores at 3.4 GHz), 8-bit video
it asks for ffmpeg path
64-bit MPC-HC uses 3.7 GB of memory for 24->60 at highest "auto" settings (and Ryzen 7 at 3.4 GHz loaded up to 50% in this mode)
32-bit MPC-HC can't even reach 1.0 "SVP index" because it's memory bound with these settings
there's an "all files" option in that window
main.setup.min_duration = 0
it should work for streaming video too
what do you see in the SVP's log?
> Could I also disable SVP and use SVP cast to passthrough 4k 24fps content with HDR?
nope
dunno, turn off or on hardware video decoder, for example
"h.264" in software mode or NVENC?
In the streaming status window there's a colored encoding performance indicator. Does it show stable 60 fps speed?
Another thing to try: "cast.encode.opts.realtime = false" in All settings. This will turn on another encoding mode when it will "pre-encode" some video as fast as it can, at full 100% CPU load.
> What specific ryzen 7 cpu?
1700 @3.5 GHz
> Is 24fps to 72fps at 4k possible?
Yes, if it won't be limited by the video card
> And woulld I get the same results in 32 bit mpc-hc?
32-bit players are not a right choice for 4K
> wouldn't the 8700k also work for 4k?
yep
Ryzen 7 8-cores, MPC-HC 64-bit - SVP @4K CPU load is less than 30%
ensure that encoding settings are not too heavy for the hardware to do real-time encoding
adjust the bandwidth
try another Android player (MX Player is fine)
> Creates artefacts with the usual intermittent stop/start
I don't get it. What do you mean?
