Never used any kind of video filters etc. and I don't see why this should be the job of a decoder.

I have no complaints. I use LAV religiously and it always works great. And when it doesn't, I whine. LOL! No, seriously, Nev has done a great job on this project. Think about where we'd all be without LAV.

You never really have an argument if your feature is only useful for pirated movies. I think it's rare to have owned the source once but not anymore, so the "just encode into a less demanding format" holds pretty strong. I'm sorry if I'm wrong, just saying.

And why is that? Such political/ideological considerations should not be part of the decision process, IMO.

These days GPUs are powerful enough to process such denoising in realtime.
If this is successful for next step i would like to have complete QTGMC deinterlacing with FFT3DGPU for noise processing
I guess there is no interest in this.

Just started using LAV Filters. Noob questions:

What does checking "audio bitstreaming" in the Audio LAV do? (Have a 5.1 speaker system connected via 3 3.5mm jacks)

What's the difference between DXVA copy-back and native?

Thanks

Forum rules, don't blame me.

Bitstreaming is for S/PDIF, HDMI or something like that. The digital stream is sent to your receiver, which handles the decoding. Not useful for you.
DXVA decodes the video in the GPU, and you can choose to either render this directly from GPU memory (native) with a renderer that supports this, or copy it back to main RAM (copy-back). The former is slightly faster and uses less power, the latter allows you to insert post-processing filters and use any renderer, like it was decoded in software.

With all due respect, that is nonsense.

Of course it's not possible to substitute every feature of avisynth with lav.
IMHO at least the part that avisynth is dead and outdated is not nonsense.

@ pokazene_maslo -
On official site and SF, yes it's outdated.
But look here Avisynth 2.6 MT (2012.05.16)

You are trying to compare 2 very different things. LAV is a video decoder. Avisynth is a scriping engine that allows you to do basically anything to video.

With nnedi3, QTGMC, Masktools/MVTools (or yatta...) and now evenwith the 16bit filtering with Dither, what aspect exactly is there in which avisynth isn't light years ahead of alternative solutions?

Not to mention the customization option of filters and the script itself, allowing non-linear filter chain and all...

MP4-files with only audio inside DC-Bass Source Mod does except though. Will update documentation accordingly next time.
Thank you for the information.

Nev,

I suspect a regression in Lavaudio when opening a DVD folder via the .IFO file.
MPC-HC consistently crashes (all versions I've tried) if I open the .IFO file from the \VIDEO_TS folder.
What happens is that the video starts playing, but no audio.
(the crash window from MPC pops up)

This is what my event log says :
Code:
Log Name:      Application
Source:        Application Error
Date:          1/06/2012 17:00:47
Event ID:      1000
Task Category: (100)
Level:         Error
Keywords:      Classic
User:          N/A
Computer:      Win7
Description:
Faulting application name: mpc-hc.exe, version: 1.6.3.4948, time stamp: 0x4fc63f56
Faulting module name: LAVAudio.ax, version: 0.50.5.0, time stamp: 0x4fc67cec
Exception code: 0xc0000005
Fault offset: 0x00007873
Faulting process id: 0xbdc
Faulting application start time: 0x01cd400751fe7ff5
Faulting application path: K:\programs\MPC-Homecinema.1.6.2.4802\x86\mpc-hc.exe
Faulting module path: k:\programs\LAV Filters-0.50\x86\LAVAudio.ax


After rolling back to the original LAV 0.50.5, the crashes are gone.
Could you in mean time try it yourself (open .IFO file)
I'm aware DVD playback is not yet supported, but Lavaudio used to work well in this situation.
Thanks in advance !

PS
Something I forgot : if I block lavaudio, there are no crashes.
Reading the vobs 1 by 1 using Lavvideo/Lavaudio/Lavsplitter is OK, no crashes.

All tests are done with non-encrypted dvd's on my HD.

added 02-06-2012
I tested build a73f6321f4f7 (most recent from git) and the 2 builds before : these are all affected.
I'll try to figure out between which builds the regression was introduced.

It is impressive how far LAV has come in such a short period of time!

I have little problem though. I am using LAV Video Decoder with DVBViewer in a push graph (live source). Problem is that when using 'ffdshow Audio Decoder', audio and video are not perfectly in sync most of the time (tried several German and Austrian HD broadcasts). When using LAV Audio, everything seems to be ok. I am missing a mixer there though which is why I use ffdshow. I could not yet reproduce it with a recorded file (pull graph). I may try a longer recording and check how it plays out over a longer period of time.

CyberLink Video Decoder + ffdshow Audio Decoder are in perfect sync und a push scenario.

Any idea?

Have you tried using ffdshow audio as a post processor after LAV Audio in your graph? That should give you the best of both worlds.

That was my idea too. I will try that. Not done yet. Hopefully ffdshow as a post-processor only won't kill the sync as well.
