Is there a simple way to check if the hardware decoding is enabled? Like in MPC! (a indicator on screen for few seconds!).

Press Ctrl+M, go to Modules Tree and look for a generic module under the avcodec decoder module.

Re: How enable GPU decoding?

Hello, I'm also having some trouble with this. I have a 6600K and a GTX 1080, Windows 10 x64 and VLC 2.2.4 Weatherwax.
I'm trying to play a 4K x265 HEVC 10bit movie, but my CPU usage goes up to 80-100%, the video lags and colors are weird.
I tried the "DirectX Video Acceleration (DXVA) 2.0" but it makes no difference in any way.
The only programs that can play the file flawlessly is Window's "Movies & TV" as well as Windows Media Player. In these two programs it only uses 2% CPU and the GPU ramps up the clock speed and memory clock for about a minute and then goes back to pretty much idle.

Is there no way to play the movie equally effortlessly in VLC? Cause obviously i don't wanna be stuck with WMP lul

I solved the problem with nightly build 3.0.0 and DirectX Video Acceleration (DXVA) 2.0. It works perfectly now, i guess it's broken in 2.2.4 =)

First excuse my english, I'm not a native english speaker.

My question is: Is the GPU decoding in VLC player still not working ? :?

I'm using Windows XP (& Service Pack 3) and VLC Player 2.2.6 (32Bit)
My Graphic card is an Asus EAH5570 Silent.

GPU decoding is not working for me :( , so I would like to ask why.

1. Is it because the function is still broken inside the VLC player ?
or
2. Is it because I'm using an "old" Operation System ?

By the way, GPU decoding works fine for me with Media Player Classic - Home Cinema 1.7.10 (32Bit) and LAV-Filters 0.69 :D , so it seems the problem lies within the VLC player.

Yes, because VLC is using DXVA2 which means Windows Vista or higher is required.

Well, that's strange because the LAV-Filter (Version 0.69) in Media Player Classic - Home Cinema 1.7.10 (32Bit) also use DXVA2. :?

Just look here:
https://www.team-mediaportal.com/wiki/d ... figuration

Like dicribed, in the LAV Video Filter you can choose between DXVA2 "native" and DXVA2 "copy-back"
I'm using the "native" Option and like I said before it works fine with Windows XP.

GPU-Z and HWINFO32 both showed me a GPU usage between 98-100 % when watching videos with Media Player Classic, so GPU decoding must be working. :D

Perhaps VLC Player is using another sort of DXVA2 which requires Windows Vista or above as Operating System ? :wink:

It would be a "nice to have", but it's not much of an issue (for me) if GPU decoding isn't working in VLC Player.
I've got a 3,8 GHz AMD Quad-Core CPU in my PC which had enough power to do the Video decoding "without breaking a sweat".

I use VLC 2.2.8 ver.
I want to play RTSP stream from IP cam, but with very low settings of stream (low resolution and only 15 fps was set on cam settings) this stream still freeze in VLC. DXVA2 is using, but no one different between use it or not. What settings must be set for normal view without freeze?

sorry for my english:)

Use the latest Nightly.

I was trying to find a solution for my stuttering 4K videos as well, als VLC 2.2.8. just brought my i7-4790 to the max. and my GTX 1070 did nothing.

Downloaded the latest nightly: https://nightlies.videolan.org/build/win64/last/

And No everything plays smoothly at 1-2% CPU use and ~10-20% GPU usage.

Got the 3.0.1 version just yesterday, I'm on a GTX 1080 playing 1280x720 mkv file, and had barely noticed a small hiccup in the video about every 2.5-5 minutes. Wasn't really all that bothersome until I realized it.

Set the hardware decoding to (DXVA) 2.0, no such issue. Double checked what automatic selects for my system, Direct3D11 - Ahhh!

Have to say, I really am impressed with this new release. The very fact that I can chromecast from it, just made my night all that much better. (been a long time waiting for that on winders)

Hi.

¡Yo también!

I've also been noticing little flickers or "micro-pauses" occurring in the video playback (the audio seems fine) since switching to v3.0.1 a few days ago. The majority of my videos are 1080p or 720p x265 MKVs.

I'm wondering whether that "Ahhh!" in JustJinxed's post means he/she/they found a solution.

It seems my ignorance simply knows no bounds, so I'm afraid I have no idea whether adjustments to codec settings (or deinterlacing, maybe?) could help. I've basically just left everything in those departments alone, which seems to mean on automatic.

I'm running Windows 10 on a 64-bit ASUS GL553VE laptop (Processor: i7-7700HQ CPU @2.80GHz; RAM: 16 GB; Graphics Cards: Intel(R) HD Graphics 630, NVIDIA GeForce GTX 1050 Ti).

I'd love to get this sorted out. (I could always revert back to v2.2.8; there didn't seem to be any micro-blinking with that version, but it couldn't play 8-channel AAC audio, which is getting more common these days.) Help from any VLC gurus out there would be much appreciated!

Thank you!

What do the logs say when you have such hiccups ?

Hi, robUx4.

Thanks for responding. To be honest, I wouldn't even know what to look for in the logs.
Is a log compiled for each video? If so, where is it stored?

If you or someone wouldn't mind taking a look, what's the best/preferred posting method? Pastebin link, maybe?

Thank you!
