nevcairiel, I encountered an ogg file which cause trouble using the latest LAVFilters 0.54.1.

I have sent you splitted file with pm. Please take a look at it.

The ogg splitter with mpc-hc handles it very well though.

Any chance you can enable VMNC support, nev?

LAV Video
- The DXVA2 Native decoder can now properly detect hardware support for video resolutions
- Allows 4K DXVA2 decoding on NVIDIA
- New options to control which resolutions are being handled by the hardware decoder (SD, HD and 4K/UHD)
Does that mean if the 4k option is selectable that my graphics card should support 4K DXVA2 decoding ?

Tested with the 4k videos from youtube. And MPC-HC info screen says "Not using DXVA".

Yes the new "UHD (4K)" option is checked in lav filter.

My graphics card is 1 Nvidia GeForce GTX 470.

List of graphics cards supported? Perhaps add to faq on front page?

Update: http://en.wikipedia.org/wiki/Nvidia_PureVideo#Table_of_PureVideo_.28HD.29_GPUs

So looks like my card does NOT do 4k. Darn!

If your card does not support 4k then the option in lav filter should be grayed out as to not make the user think their card supports 4k when it really does not.

madVRs overlay mode has nothing to do with the "Overlay Mixer", completely different things.

Thats not possible. It will always show all options, the config does not have access to the decoder itself to check for such things (and some decoders like QuickSync or CUVID don't tell me such infos, they just fail at decoding 4K and trigger the software fallback). This will not change, it would be way too much effort for a visual fix.
Resolution support may also depend on which codec is used, so there is more combinations possible then the UI can show.

Can you give approximate ETA for ordered chapters/editions support in LAV Splitter?

Depends on the renderer, but on e.g. EVR or madVR with standard settings: yes, the graphics card will do the deinterlacing. This is done by the renderer and not by LAV, though.

Had corrupted Intel-DXVA decoding a few days ago. Forgot which clip it was.
Found it today. Installed 54.1, no corruption. Perfect, thanks =).

Hallo nev, is it possible that LAV Audio sometimes overflows when using mixing with clipping protection (very loud btw) and integer output formats (needed for some of my tools)? Normalization is fine but much quieter of course. BTW is dithering used when converting floats to integers? And do you use the mean or rms for normalization?

Is there any reason to use DXVA2 over quicksync? Does it offer any performance improvements when used along with madvr?

It's similar in the sense that the presentation isn't copied back to main memory(hence no screenshots) which would mean less potential for glitching/stuttering. And aero can continue to be on. I guess less stutter is the reason to use Overlay so madVR may help there. Not too sure.

Hello, a little advice needed please.
I can not get LAV splitter to work with dvd's. The problem started after some software upgrades (was perfect before).
LAV video is working with dvd, including Hardware acceleration, and LAV splitter is being used for just about everything except dvd's.

I have reinstalled drivers and LAV back to the last known working combination without success. I have tried the latest release of mpc-be and mpc-hc with 54.1 LAV filters. I also tried manually cleaning out the registry before reinstalling, but I keep coming back to the same point (everything fine except dvd's).

I am running Windows8dp and wish to avoid reinstalling (I had a disc image which conveniently disappeared)

If anyone could give me some registry values to check I would be grateful.

PS- I had individual vob's playing using LAVsplitter but could not get the disc as a whole to play fine.

When I'm playing a flac file it stops 2/3 of the through and MPC-HC says playing but nothing happens even when I play/pause the player.

No problems here (using 0.54.1)

I'm getting regular player crashes (DVBViewer + Media Center 18 w.custom video mode) with 0.54.1 after a couple of minutes. Not sure if it's LAV, reverted to 0.53.2 and it works fine for now. Win 8 x64, AMD 5670.

I hope you updated LAV in MC properly, in its plugins folder? Otherwise the version mismatch of its integrated plugin and any stand-alone installed versions can easily result in crashes.

What kind of video? Everything? Anything special?
The only changes between 0.53.2 and 0.54.1 are either DVD or DXVA related, nothing much else. Do you use DXVA?

No, haven't touched that. I thought MC does not use it's own plugin folder in custom mode (where you manually select Directshow filters), only in RO mode. DVBViewer crashes too, though.

Only tried regular DVB-T SD H.264 channels, using DXVA copy-back/native. It'll almost always crash after a while. I'll keep using 0.53.2 and post back if it crashes, too.

It plays fine, and then without doing anything it would suddenly crash?
In Live TV only, in MC18 too? Or also file playback?
