Prerequisites
Windows® 7 (SP1 with the Platform Update), Windows® 8.1, or Windows® 10
Version 1.4.6: AMD Radeon Software Crimson Edition 17.12.1 (17.50.02) or newer
Try the new .130 build.
- should be a little bit less CPU demanding
- added AMD AMF option (*)
(*) I can't check how good or bad it works, so please leave your comments 
See the encoder options in "All settings": cast.encode.opts.h264_amf and cast.encode.opts.hevc_amf
намекает что не каждый может себе позволить SVP вместе с svpcode
Videostream encodes video for streaming with 5M bitrate.
> Nvenc doesn't matter as my gpu isn't being used when streaming anyways, mostly just the cpu.
You didn't read what I wrote 
Interpolation uses "mostly the cpu" and NVENC works just fine.
...and stream 720p only...
===
I'm wrong, it can do "native resolution", at least for 1080p...
but no NVENC 
and 5M bitrate at maximum
nope, it'd be too predictable 
nothing can stop you from streaming via SVPcast with frame interpolation off
> I found the setting for it on my own.
good for you! now look in SVP's Events log...
and play some "normal" video, not 4K
your hardware obviously is too slow for streaming 4K
> там можно выставить 120 фпс хотя у меня моник 60 фпс?
можно...
120/144 тяжело только без GPU-ускорения
а так - почти вся доп. нагрузка идет на GPU
Tsubajashi
subtitles are tricky... but they are obviously in the todo list
FYI, the next version won't need secondary ffmpeg process to run so it will fix your issue, hopefully
Duckers
Where do i paste that?
if you're asking this - just don't do anything
svpcode не устраивает? почему?
ok, will try to enable AMF encoder in our build of mpv 0.28...
нет
сбросить профили в SVP в "5G", а потом выключить GPU-ускорение в SVP же
this's not a part of ffmpeg master
you should ask ffmpeg developers to implement this
===
ha, in fact it WAS finally merged into ffmpeg 3 weeks ago
"good news, everyone!" (c)
So, what can i try to do with SVPcast to get it to actually trigger the shield tv or tv to play ongoing streams?
I dunno... fix what you broke
- does SVP detects Chromecast device(s) correctly with the actual IPs? (see the log)
- you can enable verbose logging with "cast.verbose = true"
> using the other command i should paste still does not work for some reason
with the same "Invalid data found when processing input" error?
> if it even exists on linux
not yet
no, it won't help
a suggestion from google: add "-nostdin" to ffmpeg args

downloaded the very same file, and the command line above works as expected
the log doesn't contains ffmpeg output so we don't known why it exits 
you can run this manually in a cmd window to see the full output:

SVP auto settings #3: "13:21:53.015 []: Profile: using auto values [3]"
mpv - ~65% CPU load
streaming (12M, NVENC H.264) - up to 80% load, solid 60 fps rate
streaming (12M, software x264, "superfast" preset) - 95% load, 41 fps
SVP auto settings #1: "13:21:53.015 []: Profile: using auto values [1]"
mpv - ~75% CPU load
streaming (12M, NVENC H.264) - up to 90% load, only 53 fps rate (!!!)
Conclusions:
1. ffmpeg needs some CPU power even with hw encoder in use
2. if there's no enough CPU power left then NVENC performance will be degraded
3. you need a high-end CPU to stream 4K, 4 cores i7 is NOT enough
> Имеет ли какое-то отличие в качестве пресет 5g от пресета 5c?
Скорее да, чем нет
> Вопрос - будет ли страдать качество видео если я перейду на 5c вместо 5g?
Никто не мешает никуда не "переходить", а просто выключить ускорение GPU. Тогда уж точно все параметры останутся теми же.
Плюс сам по себе рендер кадра через GPU более качественный, чем через CPU, но я не уверен что это видно без лупы на стопкадре.
вот быстрый гугл показывает, фиг знает насколько это относится к нам
We are aware the 10.13.2 update breaks our OpenCL implementation. We'll update when we have more to share.
и еще:
https://www.tonymacx86.com/threads/nvid … 25.239852/
NVIDIA has released alternate graphics drivers for macOS High Sierra 10.13.2. These are separate from the drivers Apple ships as standard, and should be considered experimental. These drivers have been known to solve OpenCL issues with certain applications, as well as providing better native GPU power management for certain devices.
я вот не уверен так по поводу "само"... но у меня и мак простой, без дискретки
