thinking of getting a small 11 inch cheap laptop or tablet purely for videos on the go, and was wondering what sort of cpu that is minimum recommended to get a smooth 60 fps interpolation.
Tv episodes will be roughly 800MB to 1GB in size 720p and movies around 10GB 1080p.
Edit: Is this one good enough?
Pentium N4200 Quad Core
Couldn't fit "for vlc" on the end of the title.
So mpc hc for some reason only plays audio now in mono on my left speaker/ear in my headphones, and i tried to reset it, reinstall it, but still only left side.
So i tried another attempt with VLC by adding svp to it with the video filters, but svp can't seem to get write access to the video filter folder. I untick "read only" to give write access, click apply and ok and it says to give admin permission to change this, press continue, it closes, but when i check the properties, it's back to being read only? Why is it so? VLC isn't running, so should "obey my commands"
Nothing changed recently in svpflow plugins except for fixed 10-bit mode in Vapoursynth plugins (in March).
Check your video driver, video renderer settings, etc.
Video driver is up to date. and renderer settings are usually stock all the time. Even tried to change some stuff, but didn't get any better. Also tried to use cpu isntead of gpu, still the same stuttering.
After the last or second last update, the framerate or smoothness with svp feels less than what it was before.. Before on normal motions, it was smooth to ofcourse some extent, but now, it stutters every 200 or 300 milliseconds in a set pattern.. No hardware changes has happend at all. Just SVP updates.
I even tried to reinstall svp (unfortunately when the website was down earlier today, but luckily had the downloader somewhere else) but still the same stutter. Might as well just watch without with all these stutterings.
It's called hardware encode (CUDA, QuickSync etc). You can check this option in advanced settings (cuda_264 or cuda_265, something like this).
It still will use CPU for interpolating new frames 24>>>60 but encode will be GPU only. It gives worth quality per bitrate though.
Alrighty, where can i find the advanced settings?
And would it not work to also make the interpolating process gpu only too? Or must that only work for the cpu itself? CAuse my cpu can't push more than around 97-120 frames per sec as of today until i upgrade to 8700k.
Your GPU is an overkill for a 4-Core processor. If you plan to transcode on a frequent basis and you don't like the processing time then maybe you take a look at 6+ Core CPUs. The problem is that they will need a RAM upgrade (DDR4 vs DDR3) so that will end up at 300$+. (Ryzen+Motherboard+RAM)
Gpu isn't a complete overkill as i game 99% with the setup. But yes, i am getting a 8700k, or maybe a 2700X (mostly heading towards intel) That will maybe increase the speed by 71% for the 8700k.
And yep. Already got a cart ready for 8700k, krait gaming mobo and 2x 16GB 2666mhz hyperX. Just need my tax return to arrive.
But isn't it possible to make the transcode gpu/cuda only?
Turn off Hyperthreading and I am sure you will see it's loaded to 100%. Windows doesn't show CPU usage properly sometimes.
Otherwise encoding setting should be edited a bit (like threads count etc).
Yeah. I'm gonna guess it's not possible to only use the gpu right? Cause i just got home and started transcoding a different movie on my main pc, and this time, the cpu is at 67% for the transcoding but only around 20% of my gtx 1080.
Cpu is a 4 gen old 4790k, and gpu is a 1080 SC.
Same as in games: CPU or GPU.
It doesn't transcode on GPU by the way, it just uses it in combo with processor as games do.
Yeah, noticed that. It uses the encoding part of my gpu. But if it goes along with the CPU, by is then the cpu only at 50% when transcoding alongside With the gpu? Shouldn't the cpu be at 100%? Unless the transcoding only is dual-core based when transcoding with nvenc, ending up with half gpu and half gpu usage?
What is the bottleneck? The storage it fetches the videos from and writing to is an m2 ssd.
Using my laptop atm to transcode a movie to 60 fps, and did go from 225 min on the cpu to 63 min on the gpu, but i could get it down to 30 min if the gpu usage would be 100% and not 50%. How come it only uses 50%?
Check your gpu drivers.
Just updated them, so will see how it goes.
right click on the mpc screen then go to
renderer_settings > presentation > tick either full_floating_point_processing or half_floating_point_processing
Gonna try with either of them ticked and see how that goes too.
I think it happend after the second last SVP update? CAuse before that, the videos was played just fine, but now i get it quite often and had to change to vlc (which i can't get svp to work with) to be able to watch anything for a long time without green screening.
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.
Ok, and i guess there's no ways to get it or program it to only use the gpu?
...and stream 720p only...
===
I'm wrong, it can do "native resolution", at least for 1080p...
but no NVENCand 5M bitrate at maximum
My shield tv has a "chromecast ultra" in it, so it can stream a bit higher than 5Mbit 
Nvenc doesn't matter as my gpu isn't being used when streaming anyways, mostly just the cpu.
So i'm probably not gonna use svpcast until it has gpu acceleration with 4k. or maybe use it for 1080p 60 fps, but it stutters a bit, so rather just "gamestream" with the shield tv then use normal mpc hc with svp.
I also find it weird that mpv doesn't interpolate when playing off a 4k movie. Also vlc i have given up on as it and svp won't co-operate at all for me.
True, but for that i just use videostream with chrome 
Alrighty, so it's mostly cpu based for streaming apparently.
Wonder how the 8700k i'm getting some time next year will compare to the ryzen 7 as it has 2 cores less, but much stronger singlecore speed. And is also 20% better than my 4790k
So until then, then i will use normal VLC to play off 4k movies and just use the "motion plus" my tv has.

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
Too slow for streaming? Then what's the nvenc encoder for then? Since the streamer uses the cpu rather than the gpu. Thought Nvenc was the encoder to use cuda for acceleration.

subtitles are tricky... but they are obviously in the todo listFYI, the next version won't need secondary ffmpeg process to run so it will fix your issue, hopefully

Where do i paste that?if you're asking this - just don't do anything
But you need the program report right?
I found the setting for it on my own.
No image on the tv, cpu at 100% gpu at 11% barely reaching up to 25-26 fps. Encoder is nvenc x264, software was just at 2 fps lol

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"
By installing svpcast, i broke it apparently lol. First stream worked halfly as long as it wasn't a 4k video as that kills the cpu and it won't use my gpu for streaming, second attempt won't even cast it when i tried a normal 1080p movie.
Yep, or i hope so, otherwise they wouldn't be detected.

So, what can i try to do with SVPcast to get it to actually trigger the shield tv or tv to play ongoing streams? Or do i just have to wait for a fix?

My go to player is mpc hc, but when testing now, the 4k movies crashes the player instantly.
And when i tried mpv with the default device being gpu. then it stutters a lot with 100% cpu, but when i set it to use the cpu as the rendering device, then it uses 24% gpu and 14% cpu.
And when i tried again with the streamer, it still used 100% cpu in cpu and gpu render device.
I am curious here how you changed MPV from using GPU to CPU. As I cannot play 4K HDR Movies with MPV using my 4790K @ 4.7Ghz right now paired with a GTX1070.
Even when testing normal 4K movies (non 10bit HDR) with MPC they run smoothly without issues or too much GPU+CPU usage, but with MPV as always it cannot handle 4K for some reason. So I'm curious to see if implementing your method above of changing MPV's default device from GPU to CPU can increase performance.
this is how.
And also, for some reason, the svp cast doesn't work anymore. I try to choose my shield tv, smart tv, but now it won't start on any of them. It has a stable framerate for a 1080p movie, but won't triger my devices at all.
when i test non HDR 10bit with mpc, it just crashes. But mpv for some reason when i tried it now, did not use the interpolation at all. It was at 24 fps.

You probably need to lower SVP settings in the video profile?
BTW, the original Google's Chromecast is very unstable playing > ~15M stream
In fact, Plex Server limits the bandwidth to 12M when streaming to Chromecast
I wonder how Shield is performing with higher bandwidth limits?
The thing is that it apparently wouldn't stream it because the framerate was not reaching what i set it to. It started fine when streaming a 720p episode at a solid 60, but struggled to get 60 fps for the 4k videop and apparently wouldn't send the image it barely was able to send because the cpu was at 100%.
And why doesn't it use my GPU? The cpu went 100% when attempting to stream the 4k video even when i set it to use gpu decoding, but it uses the cpu regardless.
I tried to stream a full size 4k movie, but for some reason when i choose encoder as Nvenc, it still uses 100% cpu with barely 30 fps?
Streaming to my shield tv PRO which has a built in 4k chromecast.
