LAV Filters - DirectShow Media Splitter and Decoders

[clsid]

With the K-Lite pack subtitles will work properly for .mkv files in WMC. Both embedded and external. It uses a special tweak to achieve that. With the shark pack you need to sometimes change decoders, which means you can't always use LAV Video.

[Hera]

When using DXVA native, it seems that certain video encodes (cropped issue?) refuse to play compared to Copy Back mode. Fallback to CPU issue?

Also, is it possible to make video codec refuse if DXVA fails?

Thanx

Thanks. Do you know what K-Lite tweaks?

woody, I doubt clsid is of much help beyond promoting Klite since he is the klite author.
On the up-side, my next release will support using the lav decoders/splitter along with loading vobsub in Media Center.
I will make the release later today or early tomorrow.

Really? Outstanding! I will look for your next release. Thank you, Shark!

For nvidia (550Ti) using LAV Video CUDA decoding with MADVR... what is the current "recomended" driver as I'm still on 285.62 (eg is the Latest OK or are there any issues?).

The latest WHQL driver 301.42 is the best driver to use currently as it fixed MPEG-4 ASP cuvid decoding and madVR works perfectly fine with it now as all madVR problems with the older 300 series drivers were also fixed.

[bejita7]

When ordered chapters/hard linking and editions in matroska container will be supported like in haali splitter?

[aufkrawall]

I think the latest state was not so soon or never.

[wanezhiling]

:) I need a tray, maybe it's never implemented though..

For good reason, imho. :)
I find downmixing and DVD support are much more substantial.

I'm trying to bitstream DTS-MA to my Onkyo TX-SR606. I have LAV Splitter set up to bitstream all formats. I have arcsoft installed and dtsdecoderdll in the LAV Filters directory. The problem is that when the HDMI cable is plugged in the LAV Audio isn't in the filter chain. If I disconnect the HDMI cable LAV Audio is used to decode. What am I missing?

[Portioli]

AFAIK, Onkyo 606 does not support dts-hd MA.

If you want to use lav audio + arcsoft's .dll you have to uncheck dts-hd ma & dolby TrueHD boxes.

You also have to use reclock as audio renderer.

[SamuriHL]

Um, as much as I hate the Onkyo 606 personally, it most definitely supports DTS-HD MA. You don't need the arcsoft dll to bitstream.

Why do I "have" to use Reclock? Also, I don't see a check boxe for DTS-HD MA in the LAV Audio dialog.

[robpdotcom]

You don't have to use Reclock to bitstream anything - in fact, it's not recommended for bitstreaming.

The check box for DTS-HD is in the LAV Audio configuration, under audio settings. Check DTS, and then DTS-HD will be available to check off (you must check off both). Also, make sure DTS is checked off in the formats section.

Thanks. There in no DTS listed in the formats section. Also, I'm wondering if I'm having troubles because I'm using Windows XP.

Woops. Look for DCA (DTS Coherent Accoustics).

[Andy o]

I don't think it's possible to bitstream DTS-HD and TrueHD with XP.

[SamuriHL]

I don't think it's possible to bitstream DTS-HD and TrueHD with XP.

With nVidia and AMD, no. With a Xonar, yes.

[Andy o]

In the case of the Xonar, it requires extra setup with the Arcsoft renderer AFAIK, so he still can't bitstream just with LAV. My money is on XP being the problem.

I have TMT5 trial installed and I copied the dtsdecoderdll into LAV Filters directory. How do I tell if LAV Audio is using ArcSoft to decode DTS-HD MA?

[nevcairiel]

Look at the status page of LAV Audio.
The value under "Codec" will show you:
- "dca" is the ffmpeg decoder
- "dts-hd ma" or any other combinations with "dts-hd" is the ArcSoft decoder

[STaRGaZeR]

nev, I just found an aspect ratio issue when using LAV and DVBViewer. It only happens when a certain combination of filters is used, so I don't know if it's LAV or DVBViewer's fault.

The issue is as follows: MPEG-2 channel, 720x576, 16:9.

LAV Video + EVR = Image is deformed to 4:3, like in here (http://i47.tinypic.com/f0bsc9.jpg)
LAV Video + EVR Custom = No issues
Microsoft's decoder + EVR = No issues
Microsoft's decoder + EVR Custom = No issues

Here I only have MPEG-2 SD and H.264 HD channels, only happens in MPEG-2 channels.

Any suggestions?

[nevcairiel]

Does the problem also show with recorded files so that i can check it?

Otherwise, use EVR Custom? :D

[nevcairiel]

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.

Fixed

Just recorded some of the offending footage, it plays fine in all situations, inside DVBViewer and in any other DS player. I can only reproduce by playing a live channel. The source filter reports 16:9 as it should, it's really strange. After changing channels I can see that it displays (very fast) at least 1 frame in 16:9, then changes to 4:3. Version 4.9.5.0 BTW.

I was using EVR Custom until now, but it stutters a bit here and there while vanilla EVR doesn't. And with all the sports events we have in June I can't allow that :D

Can you try this, see if it helps at all?
If this doesn't help, not sure why this would be happening, unless the video stream specifys a wrong AR, but then a recorded file would show the same problem, i would guess.

No luck with that build unfortunately. Here you have a sample, just in case you see something interesting in it: http://www.mediafire.com/?7qals0umhp28xiq

I have some BDs with uncompressed PCM audio tracks. Is there any way to keep these tracks lossless and be able to "bitstream" them using Lav Audio? (I know you can't really bitstream PCM, but I just want it to take exclusive control of my device as I keep Windows set to 2.0/44.1 for music streaming). I know Reclock is really the answer here, however, I'm seeing if it's possible to accomplish this another way because I play my MKVs through WMC and Reclock breaks live tv. Most of the videos have an AC3 track and I know I could just use that (or make one using eac3to I think), but I figured I would ask the experts if there's any other way. Thanks!

[SamuriHL]

It's a renderer issue, so, no there's nothing LAV Audio can help with. So yea, ReClock or another audio renderer that can work with exclusive mode is in fact the answer. I use J River MC17 which has their own audio renderer that can do it, as well.

[Traps]

I have this issue with LAV Audio decoder and i was wondering if anyone knows the problem.

Basicaly, LAV audio doesn't decode formats properly, AAC/AC3/Vorbis all have massive problems but DTS works perfectly.

Here's an example i recorded when trying to play a .mp4 h264/aac trailer for some upcoming movie:

LAV Audio: LAV Audio.flac (ftp://78.153.40.220/AiDisk_a1/DATA/LAV%20Audio.flac)

There are these weird sounds, volume changes and i have no idea what could cause them.

Similar issue with MPC HC internal decoder: MPC HC audio.flac (ftp://78.153.40.220/AiDisk_a1/DATA/MPC%20audio.flac)

With this decoder there are just these weird sounds, no volume changes.

If i use FFDshow to decode AAC it works flawlessly, AC3 works flawlessly with MPC HC internal decoder. It's weird and i have no idea what's causing this.

MPC, LAV, FFDshow and drivers are all updated to latest version.

I'm using LAV Splitter, LAV Video, madVR renderer on i7 2600k, ASUS P8P67PRO, Windows 7 64bit and Asus Xonar DG audio card.

[JEEB]

I have this issue with LAV Audio decoder and i was wondering if anyone knows the problem...
An actual sample would be the best way to investigate a decoding bug, as in most cases the output isn't exactly helpful. Also, if both LAV and MPC-HC are affected, and -tryouts is not, there's a chance that ffmpeg's libavcodec AAC decoder could be borked (-tryouts IIRC uses libav), and there might be a need to report upstream, for which a sample would be quite useful as well.

[Traps]

It was this video: Rise of the Guardians - Official Trailer (HD) (http://www.youtube.com/watch?v=ok0M25mpJl8&feature=g-hist), i downloaded the HD 720p/AAC version to my HDD and tried to play it. It happens with all AAC/AC3 files though.

Here's a small song sample, it happens with this one too: track.m4a (ftp://78.153.40.220/AiDisk_a1/DATA/Zadeta%20si%20lepa%20Ljubljana.m4a)

Do you have MPC-HC's internal Audio Switcher activated? Tried different audio renderer?

[nussman]

Did you try to enable video pre format detection?

[Traps]

Do you have MPC-HC's internal Audio Switcher activated? Tried different audio renderer?

Tried every audio renderer available in MPC HC, tried Audio switcher On/Off with different settings but nothing works. The only thing that works is using ffdshow-tryouts set to libfaad2 to decode, if it's set to libavcodec decoder i get same errors in the audio.

I thought it was my audio card but i doubt that since it works flawlessly for everything else.

[nevcairiel]

The file decodes just fine on any other PCs, so it must be something specific to yours.
My best guess is that something doesn't deal properly with float audio, but then again i don't think ffdshow or MPC-HC default to float output.
Other ideas were a specific version of optimized assembly being broken, but considering you have the same CPU as me, thats out too.

Just for the giggles, you could try turning off float audio in LAV - in fact, turn off everything but 16-bit integer.

[STaRGaZeR]

http://en.dvbviewer.tv/wiki/Options_DirectX#TV.2FRadio_Pre-Format_Detection

It works! I didn't even see that option before. Since it works with this setting turned on, it's LAV or DVBViewer's fault?

[nevcairiel]

I still don't even understand why it fails, the fact that the window size is 16:9 but the video is still 4:3 is odd, plus that it only happens on some formats .. confusing at best.

I'll try testing on some live tv stations, but somehow i'm doubtful it'll reproduce

BTW: Which decoder in LAV are you using?

[STaRGaZeR]

BTW: Which decoder in LAV are you using?

QS, but happens with software and DXVA too.

I don't know what that option does, but since it works with it it should be a good starting point.

Yeah, I honestly can't figure out what could cause this since everything else works fine, Potplayer internal decoders have no problems for example.

Anyway, i tried using just 16bit integer but it didn't fix it. I guess i'll just use LAV Audio for DTS and ffdshow for the rest.

[STaRGaZeR]

Got another issue to report. It has to do with QS deinterlacing.

To reproduce: disable hardware deinterlacing in your graphics card settings, so renderer deinterlacing doesn't work. With QS DI activated play an interlaced file and seek on it several times. After one of the seeks you'll probably start to see combing, indicating that QS DI no longer works. Now activate renderer DI and try again, QS will still fail at some point, but this time your graphics card will take over, so you won't see combing. In my testing it's clear that QS fails, and that LAV starts sending flags downstream at that point. Hope this helps to narrow the issue down.

EDIT: Another outcome is that instead of disabling DI completely, it may switch to half rate DI after a seek.

Sounds like a bug :(
Does this happen on all clips or a specific one?

[aufkrawall]

I'm getting lots lof dropped frames with QS deinterlacing and 60p output with a VC-1 interlaced sample (that one is often linked here).
30p seems to work fine.

Please post QS issues on my thread. Also, pelase give a more detailed report (at least the clips name), I don't remember the setup of all the users here ;)

[STaRGaZeR]

Happens in all clips, so it's a general issue. But since renderer deinterlacing (it can be confusing to call it hardware deinterlacing here :p) kicks in as soon as QS fails, maybe it's related to LAV too, or maybe LAV reacts to something QS does, I don't know.

BTW I'm gonna PM you a sample that crashes the QS .dll so you can have a look at it.

EDIT: same stuff when forcing DI on all frames in LAV's settings, interlaced or non interlaced files. QS breaks after some seeks, sometimes 2, sometimes 10, but it breaks. Funny stuff is that if you seek again, chances are that it starts working again :D

It doesn't occur with ffdshow, only with LAV.
So it may be more accurate to post this here, or not?
