LAV Filters - DirectShow Media Splitter and Decoders

[nevcairiel]

I fixed the filename, try again.

[turbojet]

Is it known that cuvid and lav decode a significantly different image?

[nevcairiel]

CUVID does image processing if you enable it in the driver settings. If its turned off, it should be the same image.

[turbojet]

It was inverse telecine enabled by default that did it, with it off it's bit identical, thanks, never thought ivtc would affect the image.

Is there a way to do a "silent" install of the LAV filters? I want to install them automatically on several computers but the installer doesn't seem to have any options to accomplish this.

However, the Zoomplayer install center is able to install them without any prompts so it must be possible...?


thanks!

[dead_screem]

Is there any way to have Aggressive Deinterlace only enabled for h.264? when its enabled I get problems with mpeg-2 for instance, forcing deinterlacing even when pulldown is used. This option only came about because of broken h.264 streams anyway...

Since it is Inno Setup:

/VERYSILENT

Command Line Parameter should install it without any prompt or window.

Thank you!

Please help me.
I wrote a Delphi interface to programmatically configure LAV Splitter.

I 've a TS file with two audio stream english and german.

so I tried to

SetTrayIcon to false
SetRuntimeConfig to true
and SetPreferredLanguages to choose the english one.

pLanguages := 'eng';
LAVSplitterSettings.SetPreferredLanguages(PWideChar(pLanguages));

or

pLanguages := 'eng,deu';
LAVSplitterSettings.SetPreferredLanguages(PWideChar(pLanguages));

but it does work
is it correct?

thanks

[nevcairiel]

You need to do this before opening the file, or it won't work anymore.
Also make sure to set RuntimeConfig before any other options.

[red5goahead]

yes. It work fine . thanks. :D

is it possibile to choose the audio stream by index in some way?

But it's not playable in DXVA mode (ATI hardware on signature system).

Not DXVA-compliant or ATI hardware/drivers ?

Height > 1080 (or 1088, depends on how it's checked). Won't get played with most of current DXVA implementations I'd guess, especially ATi/AMD :P

[detmek]

Plays fine with MPC-BE internal DXVA decoder, Nvidia 9500GT (VP2) and Windows 7.

You'll have to enable UHD/4K decoding in LAVs options because it only checks based on height. It'll then probe the hardware for support for this resolution, if it works or not, i don't know. NVIDIA supports "rotated" resolutions like this, i think, not sure about AMD.

LAV blacklist 4K DXVA on AMD, the resolution is limited to 1920x1200 even you enable UHD/4K decoding in LAVs options. (https://code.google.com/p/lavfilters/source/detail?r=cea9c97e221910fbbe00544ff136e410cf3d7378)

Here are some resolution-limit-test samples, made by mpc-be team, I think you will like them.;)

PS: Use latest mpc-hc or PotPlayer for the accurate result.

From the above 3, wanezhiling was right.

I did the test using Radeon 3650 and my 5750 with MPC decoder, LAV Video and PotPlayer.

MPC decoder and PotPlayer if you force it to always use DXVA regardless resolution, can actually play in DXVA mode that "rotated" 720 x 1280 clip.

So AMD supports those "rotated" resolutions, too - even in very old hardware like Radeon 3650.

On the other hand, LAV Video doesn't support it even in newer hardware like 5750 and even if you enable UHD/4K decoding.

So, Nevcairiel if you have time you can check again the UHD/4K option with AMD hardware.

[nevcairiel]

They are not very common, so its not a big thing, but i can probably make the check smarter to allow them.

[Tornado15550]

Hi nevcairiel. First off, I'd like to thank you for creating LAV filters.
They are amazing!
I have a feature request for the LAV Splitter, if you don't mind. This feature is the only thing keeping me from switching over from Haali.
Haali has an option called "Use custom media type for H.264". This option enables me to watch 10 bit video (Hi10P) on Windows Media Player & Windows Media Center.
I was wondering if you could implement this feature in the LAV Splitter.

Thanks!

[nevcairiel]

No, i cannot implement a stupid option like this.
There are plenty tools to configure which decoder is used in WMP, you don't need to use a wrong solution like this.

[Tornado15550]

Ok, could you recommend a tool that will allow me to configure which decoder I can use?

[Superb]

[zerowalker]

Could you add a status tab so you can see what bitrates it´s using and such?
As sometimes that features is just so helpful:)

[DragonQ]

I have an interlaced VC-1 file that doesn't deinterlace properly with WMV9 DMO (using either MadVR or EVR). It plays properly using CUVID. I assume it's a problem with the codec but what do I know, it might be fixable. Sample is here. (http://www.mediafire.com/?gfm27rj7tas7ug7)

It's a 1080i/25 video that was converted (pretty badly) to 1080i/30 for BD so it's never gonna look properly smooth. You can tell when it's not being deinterlaced properly by the combing though.

[nevcairiel]

Looks fine here. All frames are marked as interlaced, so from the decoders point of view, everything is fine. And i also see no combing. EVR deinterlaces it to 60p

PS:
Blu-ray supports 25i just fine, whats with the conversion crap? :d

Hmmmmm EVR says ~30 fps for me and I get combing, unless I turn on CUVID. :/

PS:

It's so that they can have one international BD master that can be released everywhere I guess. Total bullshit considering the majority of the market is in the UK and they already have the 1080i/25 master that they used for HDTV.

Are there plans to incorporate support for Matroska file segments (http://www.bunkus.org/videotools/mkvtoolnix/doc/mkvmerge-gui.html#global_split)?

The last reference about segments I was able to find is from 2011 (http://forum.doom9.org/showthread.php?p=1511668#post1511668), so I hope you don't mind me bringing this up again.

[balkerman]

Hi, could someone explain how I install and use the symbols to help debug. Also using madvr... Thanks!

Also when using 32bit mpc-hc on 64bit windows, which symbols do I use?

[cyberbeing]

Use the 32bit symbols and place them in the same directory as the matching x86 LAV components were installed to.

nevcairiel, Hi again, I got answer back from KMPlayer forum about KMPlayer + LAV problem, they ask if you could "implement a feature like in AV Splitter. It's called 'Single Output pin'. Its disabling makes it possible to switch audio tracks with KMP hotkeys.", can\would you?

[nevcairiel]

There are no plans for this, i think it has just disadvantages, and software requiring it is inherently inefficient.
You should ask KMP to support switching with the splitter.

[Pomegranate]

Hi. Do you recommend deinterlacing with LAV Video or with madVR?

Ok, so what does this mean? I got it with "PotPlayer 1.5.35741"

Could mean all sorts of things. That screenshot doesn't say anything specific. You'll need to provide more information.

Well I can tell that it happens with most files when I try to start. Not much else.

Then you'll be hard pressed to get any help. That is extremely vague and provides no actual way for nev to reproduce your problem.

[paradoxical]

To add, if you want to give nev the info he needs grab the debug symbols and reproduce the crash. Then give him the results. That is a helpful bug report.

Well, the exception is not specific. The one thing I did notice is that if I change to another splitter then LAV video decoder has an exception. Playback only starts if I change that to something else too.

:) Bug not in LAV - LAV just can do output in V210 format.
Until this is not fix in Pot - just do not use them.
Or - uncheck support v210 output in LAV Video decoder.

P.S. in MPC-BE i fix this today and can see video with v210, no LAV crash. :)

[wanezhiling]

Yes I know this.

This happened only on latest PotPlayer dev build 1.5.35741 (released yesterday) because they added v210 support too.:p
They will remove v210 next version.

Or - uncheck support v210 output in LAV Video decoder.
This wont help becasue v210 is disabled by default in LAV Video.

Great, I see at rev 2114.

[nevcairiel]

v210 input is disabled by default in LAV, but v210 output is enabled.

Oops! thanks.

I seem to have a problem with DXVA mode and dynamic format change. If i start off with a format that isn't support with DXVA on my system, like mpeg2, then switch over to h264 I don't seem to get DXVA at all. Happens with source filter -> LAV Decoder -> Evr/madVR renderers. Where as if I play the files directly, it says dxva2n

[mzso]

Why does V210 support lead to crash? I don't think I have anything v210.

You can't dynamically switch between DXVA and Software, or the other way around. You need a full reconnect to do this.

[wanezhiling]

:p Not means crash with v210 video, but with all.

You can disable v210 output (http://i.imgur.com/r2knD4d.png) in lav video, and the issue will go away.;)


PS: PotPlayer 1.5.35804 released today, has removed v210 support again, and now no compatibility issue with lav video.
