коммерческий успех gui к youtube-dl весьма неочевиден 
а как ещё один плюсик к целому SVP - вполне себе...
> Will there be an issue if I keep both 3.1.7a and 4 Pro installed at the same time
nope, just note the Avisynth version installed
3.1 doesn't work with Avisynth+ and 4 doesn't work with Avisynth 2.5
> Will using CUVID + OpenCL still lock up MPC-HC if I enable both as of the latest build?
I believe it works since... I dunno, long time ago. At least I don't have any problems with both 1070 and 2070.
Don't you want to try a 30-days trial first? oO
I'd install libasound2-dev and/or libpulse-dev before building mpv, and check the output after configure step.
а, не, могу... это так почему-то получается если "подсветка" включена. если выключить - то нет.
> Если приостановить работу SVP (из трея или горячими клавишами) то <..> при переходе из/в Full screen mode, SVP запускается
Не знаю, не могу такого повторить.
it must be supported by ffmpeg and/or video drivers installed in your system, not by SVP

it's a conversion filter, not an encoder option - https://ffmpeg.org/ffmpeg-filters.html#format-1

how? 
[vo/lavc] AVOption 'pix_fmt' not found.

1. How SVP works by default:
<10-bit after decoder> --> <10-to-8 Vapoursynth conversion w/o dithering> --> <motion interpolation in 8-bit> --> <8-bit encoder>
"allow 10-bit" OFF
2. Proposed method via lav filters:
<10-bit after decoder> --> <no Vapoursynth conversion> --> <motion interpolation in 10-bit> --> <10-to-8 lavfi conversion> --> <8-bit encoder>
"allow 10-bit" ON, lavfi: ";format=pix_fmts=yuv420p"
3. Other possible solution:
<10-bit after decoder> --> <10-to-8 Vapoursynth conversion with dithering> --> <motion interpolation in 8-bit> --> <8-bit encoder>
"allow 10-bit" OFF, needs editing SVP/script/generate.js, line 397:
res += bl+'input_um = clip.resize.'+(media.is420 ? 'Point':'Bicubic')+'(format=vs.YUV420'+(media.p10?'P10':'P8')+',dither_type="random")'+br;
4. One more...
<10-bit after decoder> --> <10-to-8 Vapoursynth conversion> --> <motion interpolation in 8-bit> --> <lavfi deband filter> --> <8-bit encoder>
"allow 10-bit" OFF, lavfi: ";deband"
5. And more...
<10-bit after decoder> --> <some super-duper Vapoursynth conversion script including deband via f3kdb plugin> --> <motion interpolation in 8-bit> --> <8-bit encoder>
(1) obviously the worst
(2) the best (?) but slowest
(3) better than (1) and worse than (2) in quality, but should be noticeable faster than (2)
(4) probably even better than (2)
(5) have not tried, the best possible quality (in theory) + slowest processing

Conclusion: we'll insert "deband" filter in case of 10-to-8 conversion in the next build
There're number of options to try.
1. Move 10-to-8-bits conversion to ffmpeg: turn ON "allow 10-bit output" and encode in "advanced mode":
- ovc: libx264
- ovcopts: preset=slow, crf=18, profile=high
- lavfi: ";format=pix_fmts=yuv420p" - w/o quotes, note ';' at the beginning!
> Gave it a try on a small sample
could you share that small sample?
"allow 10-bit output" in SVP - on or off? try both values.
----
ahhh, this's stupid cause it will automatically select 10-bit profile for x264
https://mpv.io/manual/master/#options-deband
You may want put "--deband" into code.tools.mpv_args in All settings.
I believe it's "vsscript.dll" and it's located in SVP 4/mpv64 folder, which means you don't have PATH set correctly.
разберемся...
в mpv кстати работает
и в mpc-hc работает
а в VLC действительно падает
нуу, заплатите через PayPal, лицензия автоматически не сгенерируется, а я потом вручную сделаю
> что если прога будет сама регать ключ на текущем пк, а старый удалять с базы?
ну так откуда прога знает, какой удалять (если их несколько)?
Короче, ждем апдейт SimpleTV за номером 0.5.0 b11.
Плюс для красоты - т.е. для возможности совместной работы SVP с деинтерлейсом - ждем апдейт SVP.
Что-то там у народа предложение энтузиазма не вызвало.
Используйте ProgTV / ProgDVB, там всё работает и даже с деинтерлейсом, если надо.
Как-то так сходу не получается... Наверное без допиливания со стороны разработчика не взлетит.
Да, надо понимать что в VLC фильтр SVP работает вместо деинтерлейса. Т.е. или деинтерлейс (который, наверное, важен для IPTV?), или SVP.
> у зарубежных пользователей реже возникают такие вопросы?
один на тысячу 
наверное, Display Driver Uninstaller тоже бы помог
Ryzen 7 1700 @3500 MHz, 4K/10-bit is totally playable at auto setting #4 (*) and below with a ~50% CPU load
(*) Look at the log, there must be line like this:
> 21:42:30.179 []: Profile: using automatic profile #4 /film
===
> and so is 24FPS vs 100FPS
Ah, 100 fps? this could be too much for 4K/10-bit try 60 instead.
> Should I try using madVR then and see if it fixes my problem?
it's worth trying...
install it via SVP's "Additional programs and features" and then switch the video renderer in MPC-HC's Options -> Playback -> Output
