LAV Filters - DirectShow Media Splitter and Decoders

[hoborg]

@nevcairiel:

Did you tryed to make LAV audio decoder working with MS demultiplexer for LATM AAC? Your latest build still refuse connection.
BTW, LAV video decoder refuse connection too (h.264), but that is not big deal for me :)

[nevcairiel]

Did you tryed to make LAV audio decoder working with MS demultiplexer for LATM AAC? Your latest build still refuse connection.

No i did not. The MS Demuxer does not know how to treat LATM AAC properly, it uses the same type for normal AAC as for LATM, which makes that kinda complicated. :p
Besides, i don't think its really the MS demuxer you're talking about - if you try to use it in GraphStudio, it refuses.

DivX AAC decoder is working:

LAV audio decoder wont connect:

[nevcairiel]

That claims to be using the default MS LATM AAC subtype, which is supported by LAV Audio. Since its not working, i need the full media type, not just the guid. Preferably of the not-working pin, i think its another subtype - at least it was when i tried some while back.

Well, MediaPortal TS reader (http://www.volny.cz/hoborg/tsreader.zip) have similar problem. It will connect with LAV audio decoder, but there is no sound. DivX AAC is working.

BTW, DivX AAC decoder seems to be only one decoder that is working for certain LiveTV streams. Monogram AAC decoder doesn't working (connected, but no sound).

[nevcairiel]

Decoding fails because the MediaPortal TS reader sends wrong AAC headers in the media type. I fixed that now to simply ignore the AAC headers for LATM, except when coming from LAV SPlitter. This does however mean that it might require 1-2 audio packages to get the headers in the stream, and stuff wont be decoded properly until then.

[rahzel]

i just noticed that when using LAV Audio decoder and not bitstreaming, the volume seems considerably quieter than MPC HC's built in decoder. On my desktop PC/netbook, it's quieter, but on my HTPC where I bitstream, it's fine. On my netbook, volume is almost too quiet even at full volume. Mind you, my netbook has a tiny speaker. Is there somewhere I can increase the volume?

Tried AC3, DTS, DTS-HD and FLAC.

[pankov]

rahzel,
I've noticed similar thing when using stereo speakers and letting windows mix the 5.1 channels output from LAV Audio to stereo. If I use ffdshow and it's mixer and output in stereo then the volume level is considerably higher.

nev,
is this normal? Am I doing something wrong or it's simply the windows' mixer that isn't doing the job correctly?

[SamuriHL]

This was just discussed a few posts back. There is no normalization happening when decoding in LAV Audio.

[rahzel]

i saw that but wasn't 100% sure that was the same thing being discussed.

[SamuriHL]

Well there's dialnorm metadata embedded in the streams, but, this is ignored when LAV Audio is decoding. I don't think Nev has any plans to add this.

Thanks - the higher priority of EAC3 works well!

[CruNcher]

Well, MediaPortal TS reader (http://www.volny.cz/hoborg/tsreader.zip) have similar problem. It will connect with LAV audio decoder, but there is no sound. DivX AAC is working.

BTW, DivX AAC decoder seems to be only one decoder that is working for certain LiveTV streams. Monogram AAC decoder doesn't working (connected, but no sound).

Yep those sound off issues are crazy just playback the entire file and see if Sound suddenly appears somewhere .ts streams can be strange especially with Scalable AAC and errors though DivX AAC decoder (Mainconcept is the only reliable solution currently) for such streams (to hear anything @ all) also Cyberlinks Decoder works :)

The video freezes while jumping on the timeline!
Tested on LAV Video Decoder (http://files.1f0.de/lavf/LAVFilters-video3.zip) & MPC-HC 1.5.3.3497 (http://xhmikosr.1f0.de/index.php?folder=bXBjLWhj). Connected to the player all three .ax-files (http://jpegshare.net/a5/32/a53226be9609ecee3fd45ff2011dd6e0.png.html) in external filters (http://postimage.org/image/8p3z7db8/). All the internal decoders and splitters disabled in the settings (http://postimage.org/image/8pfjysro/) of MPC-HC.

Especially well seen these freezing, if you turn off DXVA (http://postimage.org/image/2q5bgnosk/) and Fast seek (on keyframe) (http://postimage.org/image/2q5d471ac/).

[nevcairiel]

Seeking in those files works just fine here. Depending on where you seek, it may take up to a second for video to resume - this is to avoid artifacts, not every spot can be resumed from perfectly. But it only happens very rarely, most of the time its instant.

[Silent Rain]

Depending on where you seek, it may take up to a second for video to resume...

In my case it often takes 10-15 seconds! :eek:

Specification of my PC:
CPU: Intel Core 2 Quad Q6600 @ 2.40 GHz
GPU: NVIDIA GeForce 8600 GT
RAM: 4 GB
OS: Windows 7 x64 (SP1)

But it only happens very rarely, most of the time its instant.

This happens very often! Almost every time while seeking! :mad: :devil:
In Splash PRO and PotPlayer such a long freeze does not happen! Everything works like lightning! This happens only with MPC-HC!

[VenomousNinja]

For me seeking is broken in .avi files.Only in *.avi containers (The rest works great). Afful lag. When i move a seek bar slider video freezes for 3-4 sec. Using LAV filters on Windows 7 x64 and 32bit latest MPC-HC build. Internal splitters disabled.
Edit: Tested one more movie - I even got 10 sec lag on seeking...

qed :)

[nevcairiel]

The important aspect you're forgetting about is that it works 100% smooth for me, so whats there to fix?

Bugs that i cannot reproduce do not exist, and are most likely user failure or another filters fault.
So either tell me *exactly* how to reproduce them, or i cannot do anything (and wont spend any time trying to break it, because it works fine as-is)

[Silent Rain]

nevcairiel, show me your stats while jumping on the timeline (Ctrl+J) on these files (http://forum.doom9.org/showthread.php?p=1516646#post1516646). With the default settings of MPC-HC & LAV Filters !!!

[nevcairiel]

This is getting stupid. I have nothing to proof. Seeking works fine for me, and i bet it does for alot of other people, or there would've been complaints before.
There is obviously room for improvement, and there also is a issue tracker ticket about that, but the state is not bad, its "ok", its just not perfect.

Unless someone can provide an actual reproducable case, i'll ignore any further comments on the matter.
I tested your files, and seeking is near-instant, maximum 1s lag.

[Silent Rain]

nevcairiel
Can you show me the configuration of your PC?

[Xaurus]

Absolutely no problems with seeking. Using latest LAV filters and mpc-hc.

[Boltron]

Windows 7. MPC-HC 1.5.3.3491. LAVFilters-0.31-135-ga1e242c Splitter/Audio/Video. Tried a variety of mkv's. No seeking issues.

[jj666]

Seeking works fine here on your first file in MPC-HC (LAVFILTERS/LAVAUDIO/LAVCUVID).

Cheers,

-jj-

[RobertinoM]

sorry .. silent rain

but I really don't understand all your "!" exclamation marks and so on ..

1) nev has nothing to proof
2) a bug is a bug if it can be reproduced in a well defined, documented manner actually it looks like nobody who has downloaded your files can reproduce it... so occam's razor ... it looks like a problem on your system ... I personally tested on three extremely different (from the hardware but with the same software setup) machines... and no freezes..

3) LAV is for free and Nev is doing a great job with it .. and nobody forces you to use it...

So if you want to help the further development ... be more specific and less arrogant ..

[mzso]

Hi!
Layman question: What's the difference between LAV Splitter, and LAV Splitter Source? (Besides the name)

[magic144]

Hi Nev,

just trying LAV Splitter Source + LAV CUVID decoder under ZoomPlayer 8RC2
For some reason, I can't seem to play The Dark Knight (VC1 BluRay) using this combination... Keep getting APPCRASH?

Win7 Home Premium, x86
Nvidia 9500GT
LAV Splitter 0.31
LAV CUVID Decoder 0.9

ps - I can (however) get Doctor Who Specials (BD, VC-1 1080i) to work using the same filter combination??!!
UPDATE - just tried Psycho (50th ann.) - 1080 VC-1 - no problems with that disc - maybe it's the BD structure of Dark Knight that's causing an issue...?

Hmm, something is weird here coz the same disc works on my other PC with LAV Splitter (however, the other PC has an AMD graphics card and I use ffdshow for decoding...). I cannot get LAV Splitter + ANY decoder to work on my Nvidia box with The Dark Knight......

[nevcairiel]

If its only happening on one of your computers, its really weird, and most likely not strictly a bug in LAV Splitter. Probably some bad interaction with something else.

To rule out random errors, try completely re-downloading and re-installing it
Otherwise, are all other components the same? Audio decoder, audio renderer, video renderer?

[nevcairiel]

Hi!
Layman question: What's the difference between LAV Splitter, and LAV Splitter Source? (Besides the name)

LAV Splitter relys on another DirectShow filter to read the file, typically the "File Source (Async)" filter. LAV Splitter Source reads the file directly.

Both have their different uses, and different players prefer different ways to use it.

[magic144]

Hi nev - looks like it was user error - I had misconfigured the ffdshow Audio codec and disabled TrueHD... this obviously makes ZP puke (though I thought it would have done something more graceful like tell me it couldn't build a graph!)

sorry to have jumped the gun! - great filters - possibly replacing all others so far!
I'm really impressed it plays the 1080i VC-1 Doctor Who (well, the CUVID does) - that's a milestone - if only there was a LAV DXVA!

I guess once LAV Audio can downmix to 2.0, I wouldn't need ffdshow Audio on this box anyway - fingers crossed for future features, but no biggie.

[nevcairiel]

Glad you managed to work out what caused your issue. :)

[jmone]

.... if only there was a LAV DXVA!


What wil DXVA give you that LAV CUVID will not ? (on a nvidia GPU of course)

[magic144]

@jmone - nah, I meant for use on my other PC which has ATI/AMD of course :-)
(and no, I don't hold out too much hope for LAV DXVA, too bad!)

Guys, please, show me your stats while jumping on the timeline (Ctrl+J) on these files (http://forum.doom9.org/showthread.php?p=1516646#post1516646). With the default settings of MPC-HC & LAV Filters. I want to look at the chart peaks and compare them with my peaks.
But before that, turn off DXVA (http://postimage.org/image/2q5bgnosk/) and "Fast seek (on keyframe)" (http://postimage.org/image/2q5d471ac/). This is really important.

Edit: Tested one more movie - I even got 10 sec lag on seeking...

Yes, I also have the video that freezes for 10-15 seconds!
These same problems with seeking confirmed all the Russian community (http://forum.ru-board.com/topic.cgi?forum=5&topic=35155&start=0) members of MPC-HC!!!

it looks like a problem on your system

Splash PRO and PotPlayer has no problems with seeking. So the problem is not in my system or in my PC. Most likely, the problem in MPC-HC.

[Blight]

I haven't had a 10 second delay in freezing, but I did have a few other weird oddities.
Sometimes (not always) when I seek a 720P MKV file several times quickly, the video goes into slow-motion that can take up to 10 second to right itself. When it goes into this slow motion state, additional seeking can make it worse and take longer to recover.

It doesn't happen too often.

[AmshTemp]

Morning nevcairiel
I reported yesterday a new broken file to lav bug tracker "Issue 41" but since that issue was marked previously as "Fixed", I am afraid that it might have slipped your attention. I didn't want to flood the issue tracker since this has possibly similar issue as the one fixed.

[CruNcher]

Lav Splitter doesn't connect to the default WMVVideo Decoder DMO (DXVA (WMV3)) {33564D57-0000-0010-8000-00AA00389B71} it falls back to the Lav Video/MPC Video/ffdshow Decoder (Software) :(
It works with the WMV ASF reader but the problem is that Lav Cuvid doesn't support that :(
I can get either one working accelerated this way but both isn't easy possible as the splitter needs to be switched currently based on the different inputs (WMVA,WMV3 (partial acceleration VP2) .wmv)

[nevcairiel]

The WMVideo Decoder does only use DXVA in WMP, it does not use DXVA in any other player, so go use another decoder. :p

[CruNcher]

ehh who says that ?


It works here i use the WMVideo Decoder to accelerate WMV3 (MP) on VP2 (IDCT) and Lav Cuvid for the WMVC1,VC1(ts,m2ts),WMVA (.wmv,.asf) (IDCT) parts it's just a bit problematic to use both as currently i need to switch splitter WMV ASF Reader + WMVideo Decoder (for the WMV3 part), Lav Splitter + Lav Cuvid (for the VC-1,WMVA parts) and Lav Splitter + Lav Video for the WMV1/2 parts all inside MPC-HC :)

Lav Splitter + WMVideo Decoder support is currently really missing (Lav Video is ok but no DXVA it's not a real big loss for a Desktop especially with only IDCT decoding support but it would be nice to have it not only for VC-1 but also MP WMV3) ;)

Theres also a second possible solution but it shows up a sync problem with Arcsofts Decoder and Lav Splitter for WMV3 (MP +WMApro) files .wmv, seeking gets unsync and it doesn't recover (VC-1 timestamp option doesn't help) :(
Lav Splitter + Arcsofts Decoder and WMVA (AP) streams are ok only WMV3 streams getting unsync @ seek in both Software as well as DXVA decoding in combination with both WMVAudio Decoder DMO or Lav Audio (it doesn't seem to be stream specific happens with any WMV3 stream here .wmv).
Arcsofts own ASF Splitter works fine obviously in all cases (though as you can guess isn't working with Lav Cuvid nor Lav Audio), so to me it looks like a interoperability problem in the handling of ASF,WMV @ seeking between Lav Splitter and Arcsofts Decoder.

[hoborg]

Decoding fails because the MediaPortal TS reader sends wrong AAC headers in the media type. I fixed that now to simply ignore the AAC headers for LATM, except when coming from LAV SPlitter. This does however mean that it might require 1-2 audio packages to get the headers in the stream, and stuff wont be decoded properly until then.

That mean you make LATM working with MePo TS reader? Can you please share test build with your update?

BTW, do you think it is possible to make working thier TS reader handle LATM + LAV audio decoder better?

[nevcairiel]

There will be a new build soon.

Everything is possible, the problem is just that most splitters dont actually support LATM, they manage to recognize it and output it, but they dont know enough to extract stream information.

[magic144]

Hi,
just ran into something I didn't realize... does LAV Splitter not support chapters in Matroska files? (I don't mean the ordered chapter/multiple version thing, I just mean basic, run-of-the-mill embedded chapters) - there are comments in this thread/CHANGELOG that chapter support was added some time ago?

I noticed today that an mkv file with chapters allows chapter selection with Haali but not with LAV...
(using ZP8RC2)

thanks,
m

[nevcairiel]

Normal chapters work just fine for me in MPC-HC.

[magic144]

I see that... must be a ZP thing... how do chapters fit into the filter plumbing - does the player have to know how to get the info from the source filter/splitter somehow??

[Sebastiii]

Everything is possible, the problem is just that most splitters dont actually support LATM, they manage to recognize it and output it, but they dont know enough to extract stream information.

it's open source too, i hope we can modify it, what we need for this ?
Thanks Nevcairiel :)

[CruNcher]

Opps i was wrong lav splitter and Arcsoft Decoder doesn't get unsync only @ seek but it gets continuously more unsync during playback time too (WMV3) :(

Still there is a visible utilization (Playback) advantage even with just partial acceleration (IDCT) compared to Lav Video directly

Arcsoft DXVA (VP2 IDCT):
