LAV CUVID Decoder - High Quality Hardware decoding for NVIDIA - Page 50

nevcairiel · 1st August 2011, 22:53

Your GPU is probably too slow. You can increase your success on a low-performance GPU like the 9500 by changing the frame rate to 25/30p, and turning off HQ DXVA processing.

Why EVR doesnt show the proper stats, i dont know.

magic144 · 1st August 2011, 23:32

thanks - the HQ DXVA turned off improves things somewhat, but yeah I have to drop back to 25/30 to achieve total success

I had read somewhere that you probably need at least a GT440 with GDDR5 to avoid issues here - does that sound about right to you guys here?
I think it was this thread...

Thank you Nevcairiel for your Great and Valuable Job!
Just only one request for your LAV CUVID Decoder: It desperately lacks of "Always Do Deinterlace" option!
Please, add it.

Hera · 4th August 2011, 08:43

Any plans for Haali Renderer support?
EDIT: Or am I doing something wrong?

BetA13 · 4th August 2011, 12:09

hy nevcairiel,

first of all..Thanks so much for ur work..lav cuvid and co. does work very very well and have great value...
Im very happy with my video setup now..Its just one little thing that i dont like...
Is it possible to integrate a contrast and Brightnes controll..?
sometimes the picture is way too dark, xvid mostly..and there im missing a controll to edit them..like 2 little sliders to controll that a bit..

I really would be happy if this would find the way into ur decoder...

anyway..THX a lot for ur work here..im really impressed...I also did make a thread over @ Guru3d about ur filters and codecs and keep it always up to date..The people loving it...

I'm planning on picking up a GT430 to replace my Radeon 5570 so that I can use the Cuvid decoder with madVR. I haven't had an Nvidia card for a while, so I'm not quite clear on what I need. If I want to use CUDA and bitstream HD audio, is every driver I need included with the display drivers (HDMI driver + CUDA driver?). I seem to remember a while ago that they were separate.
Also, are there any other Nvidia HDMI drivers like there is with AMD? AMD has the Realtek ones (which I preferred) and the official AMD ones that were included with the Software suite.

nevcairiel · 7th August 2011, 06:42

Everything you need is included in the main driver package. Just get the latest directly from nvidia.

rahzel · 7th August 2011, 07:04

Thank you.

Something else has recently got me to be hesitant of purchasing an Nvidia card. I see a lot of people fiddling around custom resolutions/refresh rates to get proper/smooth playback for 23.976 videos (ie, most film/movies) on a 24Hz capable display. What's the issue here? Is it that 23Hz is slightly too low (I see people saying ~23.967Hz) and 24Hz is slightly too high? Wouldn't Reclock fix this? I know right now, I have my Radeon 5570 set to 23Hz and IIRC, the actual refresh rate is 23.975. I have ReClock and movies seem buttery smooth to me... no frame drops at all.

nevcairiel · 7th August 2011, 08:44

Reclock can fix that, however if you can get alot closer to the target by simply changing some settings, why not do it? Makes reclocks job alot easier, and in theory provides better audio (less resampling)

CruNcher · 7th August 2011, 15:17

I changed now to VP4 from VP2 in the face of the 460 GTX and now i can playback 4 Girls @ 60 FPS in DXVA

compared to the max of 52 FPS with the VP2 with the 9800 GT http://forum.doom9.org/showpost.php?...6&postcount=67 gonna update with the VP4 results also im curios if my Lav Cuvid 60 FPS problems are now history http://forum.doom9.org/showthread.ph...nk#post1488268 but im confident that's the case (thx to the Hardware improved Memory Copy)

MadVR Benchmark 4 Girls + Scaling (Highest Quality)

9800 GT 512 MB (G92,VP2) = 170 FPS
460 GTX 1 GB (G104,VP4) = 250 FPS

9800 GT (G92,VP2)

460 GTX (G104,VP4)

9800 GT (G92,VP2)

460 GTX (G104,VP4)

Though i really wonder if it might be that the Bios of the 9800 GT (G92,VP2) is wrong optimized @ all and if 60 fps aren't possible with some optimization

PS: Yep the 60 FPS issues after X seconds http://forum.doom9.org/showthread.ph...nk#post1488268 are history with Lav Cuvid and also any DXVA decoder so that Cyberlinks DXVA Decoder worked even on the 9800 GT with those (the only Decoder capable of flawless DXVA playback with those test samples on the 9800 GT (G92,VP2)) becomes more impressive

Yes finally Full GPU offload Encoding works with Nvcuvenc (higher end bitrate though) reduces CPU use from 50% (partial) to 13% (full offload + cabac)

I noticed image corruption when decoding Conan the Barbarian BD.

Sample: http://www.sendspace.com/file/98q7dn

Same happens with ffmpeg based decoders.

I wouldn't go with that one. The GT430 use DDR3 memory, which is very slow. If you're looking for a budget go with the GT440 DDR5. If you plan to use it for double rate deinterlacing, then you should not consider less than a GTS 450.

Same happens with CoreAVC, DivX and Intel decoders. So it looks very much like a broken video stream.

The 9600GT is a "A" Feature Set, so at least you get H264 decoding out of it.

I am in the market for a new graphics card - could you recommend a minimum (is GT 430 ok - Zotac has a nice passive one with DisplayPort)?

CPU should be sufficient to drive it, if there's a minimum recommendation as well, I gladly take it.

Sorry about that - I'm searching now more than three days for information, and I lost track where I already searched and jumped right in here.

And I posted in the wrong thread - the one I had open for exactly the search, and not the one in the AVSForum where I intended to post.

Reading the last 10 pages really makes me look like an idiot here... :blush:

Aegwyn11 · 13th August 2011, 20:33

I apologize if I'm posting in the wrong place...really struggling to solve this one and not 100% sure where to start.

When playing back 1080i VC-1 material (Human Planet to be exact), I get jerky playback. The "jerk" happens about once every second with LAV CUVID/madVR/MPC-HC. I'm using a GTS 450. If I change to a different renderer, the symptom is less apparent because the video just isn't as smooth to begin with. If I change LAV CUVID to 30p (instead of 60p), the symptom is slightly less apparent because again, the video just isn't as smooth to begin with. If I try the clip in WMP, the symptom is less apparent (see above) and much more random. I tried Reclock and it didn't help.

Its most apparent on scrolling credits. It almost appears that its displaying a frame out of order (the credits seem to jump up, then back to the right spot).

I noticed this problem previously on another VC-1 1080i video (US version of Life). At the time I had a GT430 and assumed it was due to bandwith limitations on that card.

The VAST majority of my HD library is 24p and I never see this problem on that content. It also seems that 480i content (Mpeg-2) doesn't have this problem. Not sure about 1080i h.264...don't have any to test.

Thoughts? Suggestions?
