Really, that feature is basically useless. Its just some terribly ugly menu to select the title you want.
MC17 and some other players also have a title selector - if it gets the title wrong sometimes, maybe they should try to improve their logic.
On the topic of BD Menu support - how is libbluray going and any hence any upcoming new LAV Splitter features?

Still having issues with CUVID. It will play a video fine for a good 20 minutes then suddenly start dropping frames like crazy. If I go back I still get the dropped frames. It's weird. It only seems to do it on some files (Mostly anime).

Its a driver issue, don't use the latest beta driver, stick to WHQL or 290.36 - avoid 295.

I have no plans at this time to implement any BD Menu functionality. It doesn't fit into a general purpose splitter like LAV.

The only thing that the Installer does influence is how the splitter is setup, so if you're benchmarking just check if its really using LAV Splitter and not something else.
Unless i managed to implement some new bugs, it should be more reliable then before, though.

That would suck for Skyrim.

The 295 driver causes the problem you described, so decide what you prefer.
Can of course always just disable CUVID and use DXVA2 or software decoding, that should in theory resolve those issues.

Im not sure about these results (they seem legit but on the other side especially the Quicksync Decoder results make me wonder, though DXVA2 Copy back fits it seems more balanced out for Playback Efficiency then Decoding and it's clearly visible in any Benchmark it is more Power Consumption Efficient though Copy back shouldn't be used for Playback purpose most of the times anyways ) also i couldn't benchmark Mainconcepts Mpeg-2 Decoder this way it crashes DxvaChecker and returns very odd results back with Graphstudio (Next, no real bench is doable it just returns some crazy numbers) most probably the same issue as with the Lav Splitter crashes (though im not sure which splitter is even used as DXVAChecker has no enumeration chose dialog for the splitter anymore it seems) but i find the Intel Decoder Result quiet interesting according to DXVA Checker its ~3x more efficient then either FFdshow quicksync or Lav Video Quicksyn and ~2 more Efficient then Mainconcepts CPU only Decoder Core (with over 50% less utilization) ?

Quick question, I have a i3 2120 using MPC-HC w Lav Filters/EVR custom renderer. Under Lav Video settings - hardware decoder to use, I have 2 available options, Intel Quicksync or DXVA2 (copy) which option would be best? For BD and Remux playback ?

If your CPU supports it, use QuickSync. A i3 2120 should be fine with it.

It appears to be using it, it's in the chain listed in Graphstudio.
I've noticed that the CPU usage is around 3-5% when benchmarking after installing 0.46 and with 0.45 it's at 7-11% and yeilding 3x the result which is interesting.
Whether it's highlighting a real issue or not I don't know, if everyone else's system is fine then don't waste any time on it, thanks.

Maybe he has luck and replacing nvcuvid.dll will work (good chances if nothing majorly changed cuda wise, just placing the old driver one into the lav video filter directory should be enough, though a jump as high as +5 normally indicates a big cuda jump as well, but it's worth a try)

@Nev

Do you know why the Performance of YV12 in Lav Video is lower as the one in FFdshow aren't both the same ?

Is there a chance to see channel downmixing to stereo with v.0.47 or 0.48?

Thanks for the new version.

Hi, Nevcairiel !

LAV Video Decoder not always switch to hardware mode (for ex.: when using DVB Viewer with H.264 streams). In this case, the decoder reports that hardware acceleration is "Available", but not "Active".
It happens not quite often, but still...
Maybe 'Pure Hardware Mode' option for LAV Video Decoder will solve it?

Intel P4@4GHz, GTX560Ti

There is always a reason when it decides to switch to software mode, if it wouldn't do it, it would potentially mean that playback would fail.
Its certainly possible there is somewhere a small issue that makes it fail when it wouldn't need to, but then that should be fixed and not some mode added that bypasses the checks.

And yet, I will be grateful to you if I'll be able to decide something... at least in the option "Pure Hardware Mode".
Thank you for great Filters!

Alexey are you sure the Stream isn't 4:2:2 ? a pure hardware mode wouldn't help in that case as you would only see Garbage

@ Nev

DXVA2 Copy back does really well

https://forum.doom9.org/showpost.php...&postcount=754

though Intel got the Kernel pressure nicely under control or is this a bug ?

So does the CUDA header update to 4.1 break lav comptibility with CUDA 3.x drivers?

The headers were for 4.0 already before, did it still work for you?
In short, not it shouldn't have any impact, unless i start using new functions.

Huh? There's a CUDA 4.1? How come on the nVidia site none of the GPUs listed support anything beyond 2.1?

You misinterpret the specs.
There is GPU Compute capability, which tops out at 2.1 right now, and specifys which features are supported by the GPU.

The CUDA SDK version is just the software version to match, and support only depends on drivers.

Strange issue: using any nVidia GeForce driver since 285.62 and later, cause the problem - image crumbles, tearing into squares, etc. But if I use any earlier driver - there is no problem.
The situation repeating with every new driver release! Any version of LAV Video with CUVID acceleration faces the problem. With CoreAVC Decoder, which uses CUDA too, the same thing!
With decoders that uses DXVA everything OK with any driver...

Can someone experienced and knows how to fix?
