Hello.
Is the "Visual Retrieve Augmented Generation" feature/ extension available to download and install it ?

Where can I find it ?

More details here:

That's why I put it in "quotation marks" I'm not a developer, so it's a little difficult to figure out what is going on internally in VLC's source code. If you know the answers in those two previous questions beside the last one that you reply, it would be more helpful to me in order to un...

Hello. I have an Intel ARC A380 GPU and Window 11 - all updates installed. I did a test using the clip below and MPC-HC vs VLC. Clip: Samsung_SUHD_Journey_of_Color-50Mbps (HEVC 10bit 4K@60fps) GPU: Intel ARC A380 - Drivers v5590 (10/6/24) 1) MPC-HC v2.3.4 (Using internal LAV filters v0.79.2.18) SW d...

New strange behavior of VLC in H.264 L4.2 - 1080p60fps clips.

It just freezes after the first few frames with GPU acceleration on.

Sample here:

No, ATI 4850.

Can you give us details about your system/programs versions in order to repeat your test ?

Windows :
Catalyst :
MPC-HC:
FFDShow DXVA:

Settings of MPC-HC and FFDShow DXVA

Thanks

GPU acceleration works with these videos on MPC-HC and ffdshow DXVA without problems. I believe it's VLC issue. With ATI cards the following programs give BSOD when try to play 4K videos in DXVA mode (GPU accelerated) 1) VLC 2) MPC-HC (Internal filter) 3) FFDshow DXVA 4) DivX H.264 Only PowerDVD 10...

They only accelerate H.264/MPEG-4 AVC. When people talk about MPEG-4 they usually mean MPEG-4 Part 2 video (Simple Profile or Advanced Simple Profile) which most people associate to DivX or to XviD. And MPEG-4 Part 2 isn't hardware supported in most display adapters. Yeah, I know that's why I speci...

Funny, because ATI says it is up to software developers to support it.

ATI claims that they did their job in Catalyst 10.4
They exposed the feature inside the driver and you have to use it.
And it goes on till now, Catalyst 10.8

No?

I have already reported the crash to ATI engineers.

Is there any chance besides the fix of crash, to add the support too

Because your 5750 doesn't accelerate fully MPEG-2, so we don't use it. And because Mpeg-4 isn't part of DxVA2 So you accelerate full bitstream DXVA mode and not hardware assisted, if that is what you mean. WMP12 accelerate MPEG2 on my 5750 and ATI claims that they accelerate fully MPEG-2 (bitstream...

Hello again. My system: Win 7 x64 - Radeon 5750 - Catalyst 10.8 Using the latest VLC 1.1.3 with GPU acceleration enabled I get these results: 1) VC-1 accelerated 2) H.264 accelerated 3) WMV accelerated 4) MPEG-2 not accelerated 5) MPEG-4 ASP (Divx,Xvid) not accelerated Two samples provided: MPEG-2: ...

2) Blue screen is NOT ALWAYS driver issue.

They are.

Anyway, it would be better to argue about the support and not the blue screen of the feature

Why you are NOT surprised ? Why do you think the driver is buggy ? 1) Because those are very HD resolution 2) Blue screen means driver issue. 1) They are UHD files, but according to ATI they ARE supported I think it's up to video player developer to use the driver in a suitable way 2) Blue screen i...

Because not all people have 4core processors to play these files in CPU only

VLC doesn't support multicore H.264 decoding.

I mean that for systems with older processors (single or multicore), GPU accelerating is a necessity and not a supplement in order to play those files.

So from your answers, I do not see a big interest to implement it

Could you be a little more specific ? Why you are NOT surprised ? Why do you think the driver is buggy ? And of course last question. Are you going to add this type of GPU acceleration in your next version? I mean UHD support. Is it a lot of trouble for you? Because not all people have 4core process...

Edit: Update to Catalyst 10.8

Exactly the same behavior.

Blue screen/ crash with GPU acceleration enabled at UHD (4096 x 2304) H.264 clips

Yes I have

Yes, of course http://rapidshare.com/files/414985529/YouTube_-_Troya_HD_Test_4_4096_x_2304_23.97_fps.mp4.html http://rapidshare.com/files/414984985/YouTube_-_Kannagi_in_4K_-_2304p__4096x2304_.mp4.html http://rapidshare.com/files/414984909/YouTube_-_4096p_Test.mp4.html The files were taken by YouTube...

I use VLC 1.1.3 and I found out a problem with H.264 Level 5.1 support when I enable GPU acceleration I have an ATI Radeon 5750 - Windows 7 x64 - Catalyst 10.7 system and when I try to play UHD (4096 x 2304 ) H.264 video files with GPU acceleration enabled, I get a crash or a black screen window.
