LAV Filters - DirectShow Media Splitter and Decoders

And i need to use a decoder like lavaudio or ffdshow.

Your sound is not configured/not able to to handle 6ch PCM 32b @96 kHz.
Try to adjust the settings from your sound to do so or configure Reclock to make 24bit PCM.
I assume you not downmixing to stereo in FFDshow , are you ?.

First go to configure Reclock and set it to "24 padded in 32"' (first tab,look at PCM output)
You could also uncheck 32bit and 32bit float in Lavaudio, depending on your config, that could solve your problem already.

If you still get an error, your sound doesn't support 96kHz : configure reclock to output only 48 kHz sample rate.

This has been brought up before. The problem is with Haali, not LAV.

Nev, when I use the installer, I do not get a chance to give a directory for installation. It just overwrites the existing install.
This makes it more cumbersome to go back to a previous version to test something...
IIRC, Lavfilters have asked for a installation directory in the past, like 2 or 3 versions back (like 0.36 and before)
Could you re-implement this in the installer ?

That's how updating is supposed to be. If you wanna change the install directory, use the /DIR="full path" parameter for the setup executable.

Please, don't.

Thank you but as i pointed out with same HW and same configuration of ReClock and using the same pcm mkv (i added a sample file on my previous post) if i use Haali or MPC Matroska splitter. audio pin directly connects to ReClock (without any audio decoder) and i listen bitexact 96-24 streaming. (BTW reclock already configured to 24 bit int padded to 32)

Should be fixed for the next version. Raw PCM was not getting the appropriate media type in some cases.

Thank you


Additional note: If you select "waveout" option instead of "wasapi", Lav Splitter directly connected to ReClock but this time it's not bitexact, it falls to wasapi shared mode sure. Please try with my sample file.

Nev,
I've been doing some testing on madVR's deinterlacing and I discovered that when I use CUVID Acceleration and I set Deinterlacing to "None (Weave)" I don't get deinterlacing in madVR - it says "deinterlacing off (says upstream)". It also doesn't work with EVR.
It seams like using this option doesn't pass the interlaced flags to the renderer.
Is this by design?
How can I get hardware acceleration for the decoding and EVR/madVR deinterlacing at the same time? I'm performing some GPU/VPU Load testing and I'd like to compare CUVID to the MS DTV-DVD Video Decoder and also madVR to EVR deinterlacing.

Press CTRL+ALT+SHIFT+D ?

I'm currently testing LAV Filter 0.39 with KMPlayer 3.0.0.1442 R2 and it shows a black screen with any 720p/1080p h.264 video if CUVID acceleration is enabled. No black screen at all with standalone LAV CUVID 0.13

Does it work fine with any other players or just KMPlayer?

Hi, just a feature request. If possible can you add "Select All" and "Select None" buttons to the installer on the part where you select which codecs/splitters to checkmark during the install process? That would make installation much faster and easier as some of us use LAV Filters for only one codec and/or splitter. In my case, just your excellent H264 Cuvid.

Thanks for your kind attention...

LAV Splitter works bad on some CDXA/MPEG-PS files,mpc-hc internal MPEG splitter works fine.
sample.

Yes, I know I can force madVR to do deinterlacing and I've done it already but AFAIK there is no way to do it with EVR, right?
Also you'll have to agree with me that it's not something that can be used on a daily bases.
The question is why LAV Decoder in software mode is setting the correct interlaced flags and not in CUVID mode.
... or am I misunderstanding what "None (Weave)" should mean?

Haven´t tested other players yet.

[psymed]

By any chance, would the deinterlacing use more cpu or just gpu?

There was some silly logic error that checked the condition wrong, it was fixed now.

I thought that was causing freezes?

It doesn't from my testings. But sometimes seeking RV30/RV40 clips may cause a mute.
