LAV Filters - DirectShow Media Splitter and Decoders

[CruNcher]

We've ended this discussion in this thread for good reason. :) I'm not suggesting we simply ignore errors. I'm simply saying we should strive to make it a bit friendlier for the end user. Blatant crashing is generally NOT user friendly. :D Giving the user a way to help the developer with a nice log and graceful exit.....that should be the ideal. But, again, this is a religious debate among developers and really doesn't belong in this thread.

Yep and that's whats going in in Win7 all the time @ least i realize much more going on their then it was the case for NT5 (XP) it's just very well hidden and as said absolute non invasive avg joe would never realize that a exception was caught the application still works as nothing happened (i dunno how this can work) anyways i opened the other thread for this as i was amazed by it and the amount of data it collects :)

And I'm honestly AGAINST that. I don't want the issues to be hidden. At all. They'll never get fixed that way. The software should be robust, yes, but, you can't hide issues from the user or they won't report them.

ehh watson immediately sends out what happened to Microsoft :D

Oh good. Then Nev and madshi can not worry about it and let MS fix it. :rolleyes: :D ROFL!

[Midzuki]

@ SamuriHL:

THEY ;) have hired CruNcher alright. :D

[chaddawkins]

Sure, some day. Its not high priority (for me), as i don't even have a single file that would need it. :)
Its also alot of work...

yeah, i don't use chapters either, but if this was developed I def would
+1

[chaddawkins]

hold up, i've only been using this for a week and i just now opened a mkv file with graphedit and it tells me that i'm using microsoft video decoder to decode my file. i assumed lav splitter chooses lav audio AND video decoders .... am i missing something here? do i need to use a registry hack to get lav video to work? what am i missing?

[nevcairiel]

LAV Splitter does not choose any decoder, its all up to the application to choose which decoders are used.

[chaddawkins]

ok... i've been using WMP
I thought it chose like Haali can choose CoreAVC withouit any registry hacks...
well, then i suggest lav splitter do this :D

[CruNcher]

You know whats really crazy seeing Mainconcepts DXVA implementations failing with so many bitstreams it's crazy both their H.264 as well as Mpeg-2 have major issues they even get beaten by Potplayers (which is damn good for a no name ISV) implementation :D

[teplex]

As I don't have patience to read through 360+ pages of this topic, I'd like to ask if it is planned to get CUVID hardware decoder to work with 10-bit depth (CoreAVC also doesn't work with hardware decoding and 10-bit). Is this even doable or problem is of hardware nature (limitation of CUDA video decoder in nvidia drivers). I'm asking this because I have poor CPU (A64 X2 3800+) and 10-bit videos in 1080p reolution sometimes lag on my PC.

[kirakami]

is LAV Player planned?

Its not possible, it would have to be supported by the hardware - and the hardware does not support it.

[chaddawkins]

could someone kindly direct me to a non auto-loading version of DirectVobSub. thank you.

1st do regsvr32 /u %system32%\vsfilter.dll
create dir & copy vsfilter.dll to program files\vsfilter\
Run MPC-HC
go to External Filters > Add Filter > Browse to program files\vsfilter\
Uncheck auto-loading version of DirectVobSub
Done.

Hello Nevcairiel,
I have just started using this amazing splitter/decoder/filter. Thank you very much for this. I am having absolutely no issue so far with playing various formats I use with it (mostly 8 and 10 bit anime titles). I just want to ask from you to check if the settings am using are OK (if you have a minute of course :)):

Player: MPC-HC Build 1.5.3.3849
Internal filters used: None (All Disabled).
Output (EVR-custom pres.)
Filter Order:
Haali Media Splitter (for ordered chapter support).
File source (Async.).
LAV splitter.
madflac Decoder.
Reclock audio Renderer.
LAV audio Renderer.
LAV video Renderer.

With the above setup I can play all files flawlessly without a hiccup on my relatively old system (see my signature), even 10 bit 720p videos play at a relatively low CPU load (around 30%). If you have any input on further tweaking this for even better performance I would be appreciative.

Kind regards and thanks again for this masterpiece.

[tetsuo55]

Microsoft really does fix problems, they will even contact ISV's and help them find a solution.

To get to this point though you have to be in the top10 issue list.

Only if the problem is really on their end, though. If there's a bug in madVR or LAV Filters, I'm thinking they're not going to fix those. LOL! :)

What does File source (Async) do?
where can i download it?
i googled but couldnt find download link only msdn info

[andyvt]

What does File source (Async) do?


Reads data from files and presents it as a MEDIATYPE_Stream, saving splitters from having to implement the file source logic themselves.

i googled but couldnt find download link only msdn info

It's included in the OS.

[HeadlessCow]

Nah, they'll investigate and report problems in third-party code and provide crash dumps and, in some circumstances, analysis about what the bug is (and how to fix it).

This works for MPC-HC but I use WMP.
I need a VSFilter.dll that I can regsvr32 /s vsfilter.dll and it not be auto-loading.

chaddawkins: http://www.free-codecs.com/download/directvobsub.htm, Google's first result.

This is the auto-loading version.
I need one that is not by default

thanks anyways guys/gals but i'm still where i was yesterday :(

[CruNcher]

All of those that are really on the edge of being able to playback something and evr custom is still to resource heavy should try either Potplayers Direct3D Renderer or the same one from Mirillis inside Splash Player those are really low resource renderer and @ least with Mirillis you have everything available like on EVR (Shader,Subtittle) including DXVA :)

Only if the problem is really on their end, though. If there's a bug in madVR or LAV Filters, I'm thinking they're not going to fix those. LOL! :)

Ehh why should they fix others problems nope they wont but they gonna contact them (if the userbase is big enough the problem can be related to, the priority list tetsuo55 talked about) and also make them a offer to get access to further telemetry it's a win win situation :)

[DragonQ]

Should be getting my HTPC parts on Friday (minus the stupid out of stock tuner card). Will be hopefully using LAV + CUVID + MadVR in MediaPortal :D. I don't think MadVR works in MediaPortal though so I'll probably have to use MPC-HC as an external player.

[pirlouy]

is LAV Player planned?
You did not have answer because it has already been asked since Nevcairiel officially criticizes MPC-HC code (hence player).
He said it might work on a player... when this list (http://code.google.com/p/lavfilters/issues/list?can=2) is empty.
Yes, it's dead. :D

[rica]

Such kind of a list would never be empty for professional players as well.

So should be better:

Splitter:
Some additional codes for acceptance of DVD and BD.

Video Decoder:
DXVA support for Ati and Sandy.

Audio Decoder:
None for the time being while using free codecs.

Dunno if you are awared of PDVD, TMT and WinDVD have several issues which is listed above?

[Pat357]

Nev,

IIRC you fixed .h264 playback (raw stream) a while ago. I remember I tested it and it worked perfect then.
Now I wanted to playback the same .h264 files, but it doesn't work anymore for me...:scared: playback "stalls" at the beginning.
I tried using the Mediaconcept splitter and the Elecard video decoder : playback is OK. The latest FFPlay (16-11-11) I have also works fine.
I'm not sure if it's a splitter problem or a decoding problem in Lav-video (could still be FFmpeg related though).
I obviously had "raw video" enabled in Lav-vid.
Can you have a look at it ?

[suanm]

thanks a lot,keep on improving it,please

DXVA support for Ati and Sandy.
Why exclude NVidia ?
We have HW decoding using CUDA/CUVID which is of coure already very nice and very stable,
but DXVA2 might be more efficient as we don't need to copy the frames to "PC" RAM and back to GPU.
DXVA would skip this the copy process of the frames from GPU to PC RAM and back before rendering.
But to be honest, I believe more in software decoding than in DXVA : look how much problems & limitations DXVA (and HW decoding in general) has.
I only use CUVID for (interlaced) VC-1 because there is no proper software solution available.
It either doesn't work (FFMpeg) or it's slow/single threaded (MS, Intel SDK).

Audio Decoder:
None for the time being while using free codecs.
Huh.. ??
What about a channel "matrix" for properly down-mixing everything to stereo, or 7.1 to 5.1, ... ? And elementary "sound processing" from libav ?
It's already in the libav lib, so it's more a matter of calling the right filters from libav then having to code everything from scratch.

This is so much true ; just have a look at the forums !

Why don't you just configure it to "never autoload" ?
General -> loading -> choose "do not load" and untick the 3 boxes.
Does it still load in WMP after this ?
(I guess it's best to "log off" or restart after making the changes.)
Does this help ?

I just tried again and it seems to work just fine with LAV Splitter + LAV Video.

Please don't post that branch yet, it'll be broken quite alot before it starts being usable. Right now there is zero difference, but once i activate it, it'll break quite a bit before its finished. :)
There usually is a reason when i do stuff in branches - its not ready to be used by everyone yet. :p

Edit:
I changed my mind, its somewhat ready-ish for testing, if someone dares to.

Bitstream wise it seems no issue @ all see how CoreAVC and Mirillis fixing most issues that others DXVA implementation fail on without creating much more overhead :) the only real limits you have are anything above 8 bit and 4:2:0 though for those you can switch to the Software Decoder part for now until they get hammered for consumers into hardware which might still take a while :P

[somy]

I have a stupid question regarding which output format to choose for EVR on ATI HD5770.
It seems that NV12 is preferred for hardware deinterlacing and pulldown detection, but EVR does a pretty bad job converting NV12 to RGB32 (noticable banding allover). If I choose RGB32 I get perfect PQ, but what about deinterlacing and pulldown detection?

i'm good now, i can use the auto-load version.

Just for shits and giggles, you can try my personal codec pack for wmp
http://netload.in/datei4yM2MArCTq/WMP_Playback_Pack_2.1.exe.htm

it is LAV, VSfilter, MediaInfo, Icaros & correct registry entries to associate/play/enquue WMP with MKV, FLV and Blu-ray
x86 & x64

[CruNcher]

did someone compared Microsofts MFT vs Icaros in terms of thumbnail buildup speed/memory/io/cpu/gpu usage for @ least the default supported formats and crash stability (buffer overflows) ? bringing something so sensitive deep down into the system i wouldn't feel good without testing it carefully.

[Kurtnoise]

completely off topic...

[SamuriHL]

Admittedly that is pretty sweet.

Nothing. Use EVR CP and its dithering, 16/32 floating point surfaces options.

How does one change EVR's options? The options for EVR within MPC-HC are rather limited and that's the only way I've ever used EVR.

It is already supporting CUDA and i use it too. So i didn't need to say "it should support CUDA as well."
