LAV Filters - DirectShow Media Splitter and Decoders

[Anleck]

Thanks for the new LAV - appreciate your continued work.

I found a workaround for the problem.
Basically in Media foundation it tests if you can set a media type when it calls SetInputType
I return MF_E_TRANSFORM_CANNOT_CHANGE_MEDIATYPE_WHILE_PROCESSING
Because I still have samples left to display
So I guess LAV tries to force a reconnect, and it gets stuck in some sort of loop. It's only 1 sample every time stuck in the buffer. If i flush it, problem solved.

[nevcairiel]

Of course it needs to force a reconnect, because i need a bigger buffer to write my bigger frame into. What else can i do?

[dukey]

Good point
By the way, it's a pleasure to debug with LAV. The debug info is super useful.

nevcairiel, Hi
I just did reset my settings in KMPlayer and set splitter to LAV but now hotkey to switch audio streams in KMPlayer doesn't work but it's default splitter and gabbest works fine with the hotkey, can you fix this? (or tell me how to fix it if I can do it by some configuratio)
and subtitles can't be shown even if I choose those manually now with LAV, what can be done for it to work?
Thanks.

[nevcairiel]

LAV does not have hotkeys. This sounds like a problem with your player.

[Owyn]

ok, so my question was more like, how do I make LAv work with KMPlayer? (and if can it be done at all) . Would really appreciate your help.

Now when I use LAV in it
- internal subtitles can't be shown at all
- hotkey in KMPlayer for switching audio streams doesn't work (works fine for external audio, problem is with internal one)

with Haali media splitter goes the same thing, but with Haali if i set splitters for all formats to "system" - hotkey start to work, with LAV splitter - it doesn't

I'll write to KMP forums too but would be nice if you could also take a look ^_^

Sorry to disturb

Nev, any ETA on that "English[eng]" subtitle selection support?

nevcairiel,

I have a problem with this DVD sample, LAV 0.55.3 and EVR renderer.
http://www.sendspace.com/file/rq5twj (media fire wasn't working)

Play the first episode and then go back to the main menu, the last subtitle line stays on the screen until the menu loops and re-draws itself (DXVA Native / Copy Back or Software mode). Using CUVID the same thing happens but usually the last video frame and menu navigation markers are shown instead of the menu background, it might take a couple of tries for it to happen, usually after around 5 or 10 seconds of playback.

Thanks.

nev,

The x64 debug symbols for 0.55.3 seem to be missing.

I fixed the filename, try again.

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!

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.
