LAV Filters - DirectShow Media Splitter and Decoders

@Nev Native it's broken now (black screen) and CB (too ?) seems to fallback to software (after latest ffmpeg update ?)

Should be fixed.

[Mercury_22]

Should be fixed.

It is :thanks:
After tray icons are done any chance to add up-mixing and independent volume for each channel (to be able to control that annoying lower volume from center and surround channel )?

[nevcairiel]

Not much of a chance for channel volume, no. I told you before, i won't add such things, you will have to wait for a full matrix control.
Upmixing, i have no great interest in that because simple matrix upmixing just sounds bad.

[AndreaMG]

Do you mean you overwrote the "old" .ax files BUT you didn't RE-register the "new" ones? :confused:

FWIW, the tray icons are working as they should over here (XP w/ SP3) :)
Thanks, now I made it work by simply overwriting the files without re-registering the "ax" files and by enabeling only LavVideo the first time I open a file, then I close it and when I reopen a new one only that icon appears (as it should), but if I begin messing with all the other Lav filters by ticking/unticking the tray icon option every single icon appears, maybe I'm doing something wrong, but for now I think I won't touch anything 'cause I need only the Video Icon to be there:)

Any solution? :(

Hello, the way I use WMP12 with all codecs and splitters of LAV filters is disabling all windows codecs and splitters through 'win7dsfiltertweaker'. Disable all included 'Media Foundation' then works exclusively with LAV filters.
Sorry for my bad english.

Also, you can use Codec Tweak Tool (http://codecguide.com/download_other.htm#codectweaktool) to set preferred DS source filters for various container formats.

It didn't help. I have the sound but no video =/

I just want to have noted I solved the issue I talked about on a previous post (http://forum.doom9.org/showthread.php?p=1597548#post1597548) in this thread.

AVS files now play seamlessly in MPC-HC using the Windows AVI/WAV File Source (splitter), and AVI Decompressor (Decoder). Now GraphStudio also loads and plays the avs just fine. I don't know what prevented it from working back then, but it really shouldn't be an issue on a healthy/working system. Just to say that the lack of support of LAVfilters for avs files shouldn't be a big deal, which was what I was worried about.

Toggling the tray icon on/off a few times during playback causes a freeze. Seems related to this commit:
http://code.google.com/p/lavfilters/source/detail?r=000a91cb24ca6cf05532f67c0790f304dba6c950
Problem is gone if I change INFINITE to 2000ms.

[nevcairiel]

Just changing the timeout is obviously a bad idea, because it would result in leaking a thread object if it never closes properly.
Instead, i rewrote the thread it close itself instead of blocking the calling thread, which eliminates the need for the wait entirely.

[boyumeow]

Hi nev,
Just a request, can U make single click to tray icon when opens up menu setting pages to be placed at center of the screens, hope U understands what I mean.
Thanks.

[nevcairiel]

I was looking into centering the settings page, but its not as easy as one might think, but i'll get to it, after the holidays.

[DragonQ]

It's easy in .NET but I guess you're using C++?

[robl45]

i apologize as I'm sure this has been asked 500 times, but just quickly I have been using cuvid and just tried dxva2 with my nvidia gt430 card. cpu usage is with mpc-hc is like half what it is with cuvid. any reason I shouldn't use dxva2 from now on?

[dukey]

if its a dialog in VS
go to properties -> position -> centre -> true
;p

[nevcairiel]

It obviously is not.

If you want to save CPU power (I guess you don't have plenty of it), DVXA native consumes less CPU.
Reason is simple : with CUVID you need an extra copy from frames to CPU-memory, while this is not needed for DXVA native.

So, yes, go for DXVA all the way.

computer is 5 years old or so so not a lot of power. is cuvid going to be better? what will I be missing?

[boyumeow]

@nev,
There is 1 more thing, I open up the properties page thru' mpc external filters page, if I click the icon it will open up another same properties page again, hope this could be resolved too. I assume U could poke madshi on these matter since he has his icon long enough and I dun see those 2 problems I mention, hehe :D. But if he turn around and poke me, guess I will just lies here dead :p.

Whatever, all these will right after yours Holiday, enjoy and have your happy holiday everyday. :thanks:

That's not a problem, it's meant to work like that. If you open multiple pages, that's what you get.

[aufkrawall]

Having a problem on an Fusion E-350: It's too slow for DXVA deinterlacing with madVR (even half framerate) and YADIF doesn't work (due to DXVA?).
I think CB wasn't working well. I guess there's no solution?

[nevcairiel]

If your GPU can't even do half-framerate deinterlacing, then you're pretty much screwed. The CPU in the Fusion APUs is very slow as well, so doubtful you could pull of YADIF anyway.

[aufkrawall]

Thanks to DXVA, CPU usage isn't high when playing an HD video.
Later I'll give CB another try, but I'm afraid I'm really screwed. :(

[DragonQ]

Does DXVA2 not work with EVR on an E-350?

[aufkrawall]

Does DXVA2 not work with EVR on an E-350?
It does, but with GPU deinterlacing it's too slow too, at least with VC-1i 1080p.

[Niyawa]

Hey nev, thanks for LAV Filters, has been saving my life since months now. I have a question regarding DXVA2.

I'm using it with 8-bit videos, and it's been working well so far, but there are some videos that DXVA2 simply is not used. I'm not talking about 10-bit. For example, there's this anime with 2 Openings, one of them uses DXVA2 while the other doesn't, even thought they have the same video/container and were encoded with the same settings. I don't believe this is normal so I'm wondering if you have any ideas regarding what could be the cause. I'm using MPC-HC 1.6.6.6373 with madVR and Haali Splitter. Windows 8 x64 with Intel HD 4500. I'm using "DXVA2 (native)".

Sorry if I'm not being more detailed about it.

Edit: Thanks wanez for remembering me, was in madVR thread and forgot about it, 14 seconds is enough I presume? Here:

The one where DXVA2 is used (http://www.mediafire.com/file/umpwp5ckk80qj48/Code_Geass_ED-sample.mkv).
The one where DXVA2 is not used (http://www.mediafire.com/file/yd6y4huazufdtrs/Code_Geass_OP-sample-001.mkv).

[wanezhiling]

You missed the most detailed thing, a sample file.



The one where DXVA2 is not used (http://www.mediafire.com/file/7kugfo3rzl71ybp/Code_Geass_OP-sample.mkv).
Works fine here, haali -> lav native -> madVR

win7 + ivb 4000

[nevcairiel]

Indeed uses DXVA just fine for me too.

[Niyawa]

I guess I maybe found out what is the problem. Seems like when xy-VSFilter is present, it doesn't work. The sample I uploaded was without subs, so no wonder it works there, it worked here too now. Try this one instead (http://www.mediafire.com/file/yd6y4huazufdtrs/Code_Geass_OP-sample-001.mkv), but with xy-VSFilter renderer.

[nevcairiel]

Thats to be expected, any intermediate filter between the decoder and the renderer breaks native DXVA, and there is nothing you can do about it.

:p No need to try, you just need to learn something.

I see, didn't know about that. But that only happens with native and copy-back or with the others too? (CUVID or Intel QuickSync)

:p No need to try, you just need to learn something.
Indeed. I can literally say I learned something today. Last time I used DXVA was a long time ago when it was still at the first version (which was buggy as hell here), and xy-VSFilter didn't even exist I believe. Lately I've been trying DXVA2 so I could include in my guide, and came across the matter. It worked with internal subtitle but not with xy-VSFilter, I had to ask what exactly the "problem" could be, haha.

[sneaker_ger]

Only with DXVA2 native.

xy-vsfilter will be compatible with DXVA2 native and madVR in the not so distant future through a new interface that is similar to that of MPC-HC'S internal subtitle filter, though.

I see. Thanks guys for taking your time with me.

Hi Nev,

I noticed that if I untick "DVD" under "codecs for hardware" the HW deinterlacing does not engages, is it correct? Would be possible to be able to soft decode and HW deinterlace? Thanks :)

[nevcairiel]

That is not possible. If you want hw deinterlacing with software decoding then let the renderer deinterlace.

[AndreaMG]

Thanks Nev.:)

[wanezhiling]

Hi nev, http://www.mediafire.com/?9htn5tj84ckaotz
Tested on lavf 6d05724, 2 issues:

1. Greenscreen with dxva2 native on Nvidia card @310.70whql
2. wrong field order(should be "top first" not "bottom frst"), seems that only cuvid mode is right.

[nevcairiel]

Some files simply have the wrong field order, there is an option to switch it exactly for that reason. :p
Its possible cuvid and ffmpeg have different defaults when no field order can be determined, who knows.

[wanezhiling]

Ok, how about greenscreen on nv card?

coreavc dxva is just fine.

[nevcairiel]

I'm looking into it.

[nevcairiel]

Should be fixed.

So fast..cool.:)

Nev,

There's some glitches (no audio output at the L channel, the audio is stereo) with the audio when playing with a 720p rmvb file with raac audio after seeking for several times. This problem only appear when I use LAV Splitter, no problem with the splitter with mpc-hc 1.6.5 stable.

There's quite a few splitter problems with different containers with LAV Splitter, is there something you can do to improve it?

Anything that may help you tracing the bug, please don't hesitate to ask.

Regards,

[nevcairiel]

Sample file or it didn't happen.
For the record, RMVB is just a horrible format.

That sounds more like trolling then a bug report.

Accurate problem descriptions, with sample files, or nothing can be done.

For the record, it works just perfectly for me. :p

Hi nev, lav video decoder failed..

I can confirm this but the splitter seems to be the problem cause enabling the internal splitter in MPC-BE (http://aleksoid.voserver.net/MPC-BE/?C=M;O=A) and using lav video and audio the sample it's working using lav splitter it doesn't

[nevcairiel]

The file has a "odd" FourCC used by one specific authoring tool, apparently.
There is two ways to fix such a file, either you overwrite the type in the splitter, or you make the decoder recognize the FourCC, i decided to do the second.
