LAV Filters - DirectShow Media Splitter and Decoders

[ryrynz]

Nev, I saw your post in the QuickSync forum regarding the performance regression and also read Eric's reply, will you be looking any further into it?

You can only use GraphStudio or the the more recent GraphStudioNext with the lav-filters. (=based on Graphstudio, but more featutes).
Have a look at http://code.google.com/p/graph-studio-next/

Thanks for explanation- yes, I'm using graphstudio.

Its still plenty fast as-is, so no, i won't. I'll let Eric look into it.
The main performance difference has already been fixed by adjusting the settings i use. I'm not sure there still is a difference, none that i could measure anyway.

I know this is a longshot request, but I thought I'd at least ask . I am a long time user of Albain's Media Control plugin (I'm a WMC user). It is only compatible with Haali and Gabest splitter. I believe he open sourced the code, but I believe Albain has been MIA for some time. Is there any chance it'd be possible to make LAV Splitter compatible with Media Control? I don't have a sense of how hard it is, but I recall Albain adding Gabest support a while back in a relatively short period of time. I know you offer subtitle control via a regex of sorts, but I really like the GUI Media Control offers via the WMC player. I completely understand if its either not feasible or you are not interested however. I'd also accept an alternative GUI via WMC instead of Media Control that works with WMC instead as well (Kidding, but I thought I'd throw that out there).

I'd love to use Lav Splitter as it seems much more stable than Haali/Gabest when I played with it, but I really like the Media Control plugin/GUI.

Thanks Again

Hi Nev, not to bug you too much because I know you get a lot of requests/posts a day, but I just wanted to see your thoughts on the above? Thanks

I have no interest in such a thing.
If someone wants to work on that plugin (or something comparable) and needs some information how to interface with LAV, i'll be glad to provide it, but i will not work on it myself.

hello everyone, i used LAV Filter 0.45 with MPC-HC (30-01-2012) recently with my Hybrid Vaio VPCCA16FG

this is my specs

i7 2620M
8GB RAM Crucial
AMD Radeon 6630M (Intel HD 3000)

it's wierd that i can get video with Intel [power saving mode], but i can't get video with the AMD [high performance] ( audio and subtitle were fine though )

i used the settings here http://www.elysiumsubs.com/docs/mpc-hc-guide
nothing changed.

if i used madVR i can get the video with AMD

what can i do to fix this?

thanks before

Nev,

Could you please add SNOW to the supported decoders ?
It's supported by ffmpeg, so it should not be too much work.

With LAV I got :

LAV Splitter Source::Video

Media Type 0:
--------------------------
Video: SNOW 848x480 23.976fps

With ffmpeg :

Done, also added FFV1 because someone asked for that some time ago.

I tried to improve it a bit and its running better now, but its no full fix. RV30/40 in MKV is just muxed with terrible timestamps.

Thanks. That was me who asked it.

[Portioli]

does lav dxva2 works with madvr de-interlaced?

which is the optimal configuration of lav filters & madVR for 1080i50/60 files?

[plew]

I can't get sound from Swedish - Girl with the Dragon Tattoo BD movie using MPC-HC and LAV Audio Decoder set to bit stream. This movie has been saved using DVDFab main movie. I have no other problems playing all other BD, folder or MKV. Going to Filters I do not see Lav Audio at all. No options for audio or subs. No other Audio decoder.

This plays with TMT5 just fine. I get subs and both audio tracks.

Thanks.

[CruNcher]

Btw did someone experienced that Cyberlinks VC-1 Decoder doesn't connect with every VC-1 .mkv but denies connection with certain .mkvs and lav splitter ?
I wonder whats going on as those .mkv connect fine with Arcsofts (but Decoding is very bad timestamp issues in general with .mlv) or Microsofts Decoder it works much better with Cyberlinks or Microsofts Decoder and Cyberlinks even allows Super fast seek
Its not a Profile issue as some have the same Profile and one connects the other doesn't very strange behavior

@Nev
Not sure about this

http://www.mediafire.com/?y4czq3rkmcns19l

vlc = fail
mirillis = ok
mplayer2 = ok
mplayer = ok
avplay = not sure
ffplay = not sure
powerdvd = fail
lav splitter + lav video = fail
haali = fail
mpc-hc = fail
av splitter = fail
lav splitter + cyberlink = fail
lav splitter + arcsoft = ok

Arcsoft rarely likes to work with anyone (see VC-1 mkvs that Cyberlink doesn't accept and Arcsoft plays but wrong) this is one rare sample where it does work fine with the others and the others fail :P

The reason why I ask is because Eric's benchmarks showed no difference with the file you posted and it looks like he dismissed it and has no plans to look any further into it.

Your change in MT settings did fix part of the difference I observed but I'm still seeing a slight difference in LAV Filters in favor of 0.22 if I use it to replace QuickSync 0.24.

In FFDShow 4234 which features Rev18 (0.22) of QuickSync, I get average performance with my anime intro file.
Replacing 0.24 in the latest version of LAV Filters with 0.22 gives me consistently 10% performance increase over 0.24 which doesn't stack up vs my FFDShow results.

I'll include the intro sample here and if it interests you or Eric as to why this is happening you can look into it.

These are my bench results with this file, all tests run 5 times and averaged.

FFDShow 4234 QuickSync Rev18 (0.22) 550FPS
FFDShow 4238 QuickSync Rev20 (0.23) 550FPS
FFDShow 4294 QuickSync Rev30 (0.24) 2050FPS

LAV Filters 0.45 QuickSync 0.24 2040FPS
LAV Filters 0.45 QuickSync 0.22 2300FPS

Thanks Nev.

[nevcairiel]

Like i said before, those numbers are too high to be real FPS values. 550fps might be valid for a SD file, however 2300 is most likely a measuring error because of too short files.
Pick a file thats much longer, maybe 10 minutes or so. Sure, benchmarking might take a while longer, but the result will be much more accurate and in line with other performance results.

Also, if you're really complaining about 2050 vs 2300 fps, i'll dismiss this as well.
Find a HD file that shows a performance different.

[ryrynz]

No worries, I'll take a look at longer files. Not complaining just thought it interesting, I'll get back to you with some results later.

You win 0.22 and 0.24 give similar results.

I tested with a 20 minute H.264 848x480 episode and compared some.

With Xhmikosr's builds I get around 315 FPS =/
With release 0.45 I get 980 FPS
FFDShow 4292 (Rev 30) 690 FPS =|
Also tried latest nightly and again 315 FPS.

Some strange results.

I run into an error in MPC after registering all three filters in the nightlies that the video cannot be rendered, LAV installed from an installer works fine (Xhmikosr and release builds) what's happening there? Graphedit works with it fine except slowly.

[nevcairiel]

Xhmikosr builds don't include the Intel decoder, last i checked (so it might be software decoding at work there), or it might be an older version.
In general, i only give support for my own builds, i cannot control if anyone just messed up their build (which happened quite a bit in the past)

I can provide a recent git build when i get home from work.

[ryrynz]

Yeah I can understand the support for your builds only. I keep the Intel decoder in the directory so perhaps the nightlies aren't linking to it or something. I'll take you up on your gracious offer of the git build, thanks

[egur]

Version 0.25 beta is out with the following changes:
* Fixed handling of CCV1 streams (Haali splitter custom fourCC).
* Support for H264 AVI files.
* Optimized memory copy further. Removed ASM code. Code now uses intrinsic for both 32 and 64 bit as intrinsic code reached 32 bit efficiency.
* Code cosmetics.
* FFDShow rev4295

Great thanks, i'll update the binary i ship
