LAV Filters - DirectShow Media Splitter and Decoders

[SamuriHL]

Yea I don't know. That'd be the one quick and easy thing I can think of to try.

[CiNcH]

Didn't seem to have helped. Just tried it with LAV as audio decoder and ffdshow as audio post-processor. Video and audio are out of sync after a short time. Tried on Sport1 HD. I will try whether it is possible to reproduce it with a file. But I think that the problem is a combination of push graph (DVBSource), LAV Video and ffdshow Audio.

[SamuriHL]

Could be. That's a shame. Hope you get it sorted out.

[Andy o]

The Windows mixer doesn't work? For most cases in which you need a mixer it should suffice.

[zerowalker]

Is there any plans on making LAV dvd decoding mpeg2 files?
As currently i have to choose ffdshow or Microsoft for that.

Not the worlds most important future, but it would be neat:)

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 :

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.

[Kay Diefenthal]

hi i am new here and hope this is the right place to nevcairiel ask where / what the problem is

i use your Lav Directshow Filter Pack for my FortheRecord Windows Media
Center client

but think i have found a problem

If i give Windows MediaPlayer or Windows Media Center an url with hostname
can both not play the stream
give i both the url with ip instead of hostname work it

is that a problem of the Lav Splitter or of Windows MediaPlayer /Windows
Media Center ?

[kitame]

hello guys,

i've stumbled upon a bug in LAV splitter's subs rule, i cant seem to draw english audio.

im using this setting(advance):
http://img191.imageshack.us/img191/2609/subssetting.png

also, how do i draw the signs[eng] instead of the full sub[eng]? its a sort of english subs that only subs signs.
well simply put theres two english subs stream and i want to select the second stream >,>

edit: ah right, leaving the audio selection blank seems to null the subs rule. so i fixed the drawing of the english audio, but i still cant seem to draw the alternate english sub.

[sneaker_ger]

LAV cannot select the second stream. If it's an mkv file use mkvtoolnix' header editor to set the full subtitles to default and prioritize "eng:eng|d".

[glorp]

You could re-tag the language of the first audio stream with the mkvtoolnix header editor to "und" and leave the second stream "eng". Then it will select second audio track.

[CiNcH]

OK, A/V also seem to be async with LAV Audio, so it does not seem to have anything to do with the audio decoder or post-processor. Audio is sometimes earlier than video. So it may be a problem with LAV Video and push graph. Or maybe a general problem with LAV Video. I will have to do some more investigations:

- whether I can reproduce it in a pull scenario with file playback
- find out when this happens, so whether sync is lost after some time (and is slowly getting worse) or maybe sometimes even immediately

[dbcooper]

Is there any plans on making LAV dvd decoding mpeg2 files?
As currently i have to choose ffdshow or Microsoft for that.

Not the worlds most important future, but it would be neat:)

The shark007 codec pack includes the Cyberlink PowerDVD mpeg2 decoder, which uses DXVA and is actually very nice.

[kitame]

LAV cannot select the second stream. If it's an mkv file use mkvtoolnix' header editor to set the full subtitles to default and prioritize "eng:eng|d".

ah, thats a good idea tho that is if i can spare wrecking the file's hash =p

other than that, is there other possible options? like 3rd party add-on.

[ryrynz]

Unfortunately not.

[Mikey2]

Hi all - In the MadVR thread, we became in a discussion about if it is possible that LAV Audio Decoder fully and correctly decodes the entire lossless file and does not down-sample.

Here is a copy of my post on that thread - it explains my skepticism and in a nutshell asks: Does putting dtsdecoderdll.dll in the LAV Filters directory finally solve this problem? (It seems too good to be true! ;) )

{start post}
============

, are you sure it is not just decoding the CORE components and "down-sampling"* the lossless stuff?

I have spent many hours on this issue going back to the PAP (or lack there-of) debacle when Lossless formats started appearing on HTPC's. (That is the reason I have a Xonar card - it was the first to fully play more than the "core" parts of TrueHD and DTS-MA.)

Still, the Xonar card, and indeed the whole filter-system is quite picky when trying to play these extended formats.

From all of my research, it seems that the only way to get true lossless audio is to have a bitstream that preserves the PAP.

Theoretically one should be able to decode to PCM (which is what we are talking about here.) But I thought both because of legal reasons (MPAA and their darn un-tamperable PAP!) and limitations with the filter-graphs themselves (including the inability to read the all of the extended lossless data.)

To test this hypothesis, let's do an example:

This is the real Pin information for The DTS-MA track for the extended version of "Return of the King:"


The input pin to any decoder file isthe standard DTS core bitrate of 1536kbps


LAVAudioDecoder (IN)
Audio: DTS 48000Hz 7ch 1536kbps

The output pin's bitrate will always be larger since it is a decoded WAV in a PCM at this point.

LAVAudioDecoder (OUT)
Audio: WAVE_FORMAT_EXTENSIBLE 48000Hz 7ch 8064kbps

So using LAVAudioDecoder we have a bitrate around 8,000kbps (I verified that this is the bitrate going into the Renderer.)

Now let's try bitstreaming. First take out the LAVAudioDecoder and go straight to ffdShow Audio in Bitstream format. (For some reason that decoder is one of a small few (like eac2) that runs a weird hack that gives it access to the supplemental data.)

ffdShow (Audio) (0UT)
Audio: 0x0241 192000Hz 8ch 24576kbps

So using in bit-stream mode (that we know is lossless) we have a bitrate around 24576kbps (3X the decoded mode@)

That is a much higher bitrate than the original! (3X) Too bad bit-rates are variable and that MediaInfo cannot display a file's bit-rate. Furthermore this is not proof that the sound quality is greater - indeed any WAVE-format PCM is going to have many kbps; however, that is a significant difference and seems to show me that not all of the data is being processed even in this setup!

Don't get me wrong, I'm not married to bitstreaming - in fact I'd prefer to work in the PCM world where I can use ReClock etc, but given its history, I am always skeptical when I hear of something that does "lossless" audio cleanly. If this is truly performing software decoding on DTS_MA without any downsampling, then this is the first time I have heard of such a thing

Wow this is WAY off-topic, and I apologize. As you can tell I am more than a little interested in this. I think I will post this in the LAVFilters thread too…

Thanks for reading!
MikeY

* - "down-sampling" has been used incorrectly in this case in the past. To me (at least with DTS-MA) the issue is simply stripping the non-core data.

EDIT/UPDATE/SOLUTION: Thank you for the response nevcairiel (see below.) Essentially I am a fool, I forgot to multiply the different sampling frequencies to get the correct bit-rate.

In other words (correct me if I'm wrong,) but it looks like it is in fact working fine: the 1536 input pin is a misnomer, it is receiving and decoding the full DTS-MA signal. VERY cool stuff, if this was around a couple years ago I could have saved a hundred dollars on my Xonar audio-card! (Since DTS-MA and TrueHD can be decoded at full-quality, there is no longer any need to bitstream this.)

Bitstreaming DTS-HD needs to run at the absolute maximum bitrate possible, so it'll always be very high.
It always runs at 192kHz, 8 channels, 16-bit, resulting in 192000 * 8 * 16 = 24576000 bit per second, or 24576 kbps.
This is just how HDMI works.

[SamuriHL]

The MA extensions of DTS contain the extra channels. If it were only doing core, then you would only ever get 5.1. Trust us, we did a lot of testing around this when the ability was first added. Nev is hooking the ArcSoft decoder directly in code. The down-sampling, i.e. reducing the bit depth to 48/16 doesn't actually happen in the decoder but in the renderer. So we avoid that by using the decoder directly. In any case, yes, you are getting full DTS-HD MA decoding. At all the right bitdepth.

[Andy o]

All those bitrate numbers are not the actual stream numbers. I don't know if there's an error or if they're reading something else, but Nev has stated in the past that what LAV decoder reports is not the HD bitrate, and it doesn't matter. The 1536 kbps is clearly the core DTS-ES (6.1 or "7 channel") bitrate. The out bitrate apparently is a 7-channel (6.1) 24-bit 48kHz PCM which is likely what the 6.1 DTS-HD MA track would decode to. I don't know what the ffdshow numbers mean, if it's resampling, or if they're just plainly wrong, but they clearly are not the decoded bitrate. The sampling freq and channels just don't match.

[tormento]

I have some trouble playing AVCHD .m2ts from a Sony 1080i cam, i.e. freezing, stuttering or not playing at all.

The same works perfectly with other decoders.

Before uploading huge files, has anybody tested LAV with those kind of files?

Win 7 SP 1 32-bit, LAV Filter 0.50.5

Bug Report if I may: For many .FLV files that are encoded with VP6 or Sorenson, using LAV Splitter Source as the splitter, when the video comes to the end it will not start the video again (loop the video) but instead stops the video and/or crashes the player. FLV files that are not encoded with VP6 or Sorenson (such as AVC) work fine. I included three samples: Two vids with VP6 and one with Sorenson (note: samples are a little naughty but nothing bad)

http://www.filefactory.com/file/m9bjx5wv9hx/n/Samples_zip

I duplicated this many times with Zoom Player and POT Player:

With Zoom Player & MadVR, when video comes to the end it starts flashing and crashes the player. With Zoom and Haali & VMR7/9 it merely comes to the end of the vid and stops (doesn't loop as it should but also doesn't crash the player). Note: ffdshow is the decoder.

With POT Player & all renderers, video stops at the end and doesn't loop as it should. Note: Internal POT Player decoder is the decoder

I have only been able to duplicate this looping/crashing problem I describe with FLV files encoded with VP6 and Sorenson and with LAV Filter as the FLV Splitter.

Hope I have been able to provide you with good info and the sample vids in order to easily duplicate the same problems I am experiencing. Cheers

Is bitstreaming over HDMI hardware dependent? When I connect my Dell E6420 Laptop with HDMI output to my Onkyo TX-SR606 AVR all I get is video and no audio. I have all of the bitstream options check in the LAV Audio. Any tips?

GT 640(GK107) retail card has arrived with VP5/Feature Set D hardware decoder, unfortunately it's the DDR3 version and is extremely bandwidth starved. Personally I would recommend waiting for the GDDR5 version.

[Nezaara]

QuickSync doesn't work on my setup and I'm not sure why. I'm running a Sandy Bridge CoreI3 on a Z68 chipset. It has Intel HD2000 graphics and I have updated the drivers to the latest version, yet when loading a video with quicksync enabled, the video won't play. MPC-HC works fine, it doesn't crash or anything, it just sits at 00:00:00 and won't advance. Weirdly, using DXVA works just fine. I'm not sure if I need to change the renderer from EVR custom to something else or if there's some other obvious setting I've configured incorrectly, or if it is in fact a bug. I'm assuming it's the former, so I'd appreciate any ideas anyone might have so I can use all the features of my processor to their fullest potential.

[nevcairiel]

So using in bit-stream mode (that we know is lossless) we have a bitrate around 24576kbps (3X the decoded mode@)


Bitstreaming DTS-HD needs to run at the absolute maximum bitrate possible, so it'll always be very high.
It always runs at 192kHz, 8 channels, 16-bit, resulting in 192000 * 8 * 16 = 24576000 bit per second, or 24576 kbps.
This is just how HDMI works.

All DTS-HD streams will run at that bitrate, it has nothing to do with the actual content or what it would decode to.
You can have a Mono 48000 Hz 16-bit DTS-HD MA Stream, and it would bitstream in the same format as a 96000Hz 8 channel 24-bit stream.

If you want to test if something is lossless, then find a DTS-HD encoder, encode a WAV, decode it again, and compare.
People have done this before, and confirmed that everything is completely lossless.

So, to conclude:
Yes, LAV (in combination with the ArcSoft DLL) can decode DTS-HD MA completely lossless. There are only 1-2 exceptions, associated with very odd channel layouts, which are only working 99% (you won't find such tracks on Blu-rays, at least i never saw one)

do you have a graphics card attached? because having an add-on card disables intel IGP.

[Nezaara]

Negative. I used to have a Radien, but not only is it no longer physically in the case but I have since reinstalled Windows entirely after changing the motherboard.

I was going to add something in the DTS-MA lossless discussion about the meaning of exactly what the pin info is telling you, but seems I've been beaten to it in style. One question, though: if you are bitstreaming DTS-HD or DTS-MA, then you do not need ArcSoft. You only need it if you are using LAV to decode it (IE the bitstream checkbox is disabled in audio options). Correct? If you do bitstream, is there a way to tell nothing's interfeering with it? Either way, I am hoping that if you are streaming core then the pin info will be different in some way from what you'd see if you are getting lossless output.

Hi, can you answer this (http://forum.doom9.org/showthread.php?p=1577361#post1577361) question please.

[nevcairiel]

i dunno about the part about it being bandwidth starved since PCI-E 3.0 has supposedly 2 times more bandwidth.

PCI-E 2.0 also had plenty bandwidth.
The problem is the memory itself, not the interface.

[kitame]

kinda makes sense then, i thought he was talking about overall bandwidth which 3.0 could've compensated.

[jakmal]

PCI-E 2.0 also had plenty bandwidth.
The problem is the memory itself, not the interface.

Hendrik, I have the card (Zotac model with 2 GB DDR3) in hand right now, and am going to check out the performance later tonight.

I am assuming it is good to go with 0.50.5 version of LAV Filters for 4K decoding in both DXVA2 Native and CUVID mode. Please let me know if I need to take any precautions.

First time I am going to try madVR for 4K output with 1080p content. Won't be surprised if it chokes :) (Or, maybe 1080p to 4K madVR is a test not many are going to be interested in?)

[nevcairiel]

Unless something changed in the drivers recently, DXVA with 4K will most likely still crash.

Sounds like a driver problem, download latest drivers from Intels website and reinstall. If you installed drivers from Windows Update you'll lose QS functionality or suffer from massive corruptions.
If it still doesn't help, post your full setup on my dev thread (http://forum.doom9.org/showthread.php?t=162442).

[nevcairiel]

Reverted to avcodec with DXVA2 Native :| just like on 7750

Nothing has changed in that regard, because DXVA2 mode just crashes on 4K (on NVIDIA), or doesn't work properly (on AMD), i disabled it for Native mode. You can try DXVA-CB (which doesn't have those rules), and when it stops crashing, i can enable it.

[kitame]

oh yea, is there any news for Hi10P hardware acceleration? if not then would it be possible to create an emulated software decoding using the GPU as the processor?

the latter would be seriously all too sweet =P

Edit: wait... emulating a CPU core in the GPU entirely and forcing OS to think it has additional cores would revolutionize GPU usage =O

[nevcairiel]

oh yea, is there any news for Hi10P hardware acceleration? if not then would it be possible to create an emulated software decoding using the GPU as the processor?


Decoding is impossible, unless new hardware is released that supports it (doubtful at this time)
"Emulating" a software decoder in CUDA or OpenCL is in theory possible, but really pointless.

[JoeH]

However, cuvid worked beautifully.. for the 4K clips on YouTube, I got between 40 - 60% Video Engine Load.

Amazing. Ganesh, looking forward to your Anandtech article on the card and HTPC. :)

[kitame]

i doubt they'd develop a GPU that would be able to decode Hi10P, they'd skip it for H.625 or High Efficiency Video Coding (HEVC).

i guess it is pointless when the gain would be so small its a waste of time, but if its a temporary solution to go in parallel with the CPU so that Hi10P can be hardware accelerated via emulating software decoding(lol dumb name) and ultimately offload a huge percentage of CPU usage then it wouldnt be so pointless anymore =D

Edit: reason for the questions was an idea for making ION/E350 based HTPC to be usable again with Hi10P encoded videos.

[ajp_anton]

Edit: reason for the questions was an idea for making ION/E350 based HTPC to be usable again with Hi10P encoded videos.What makes you think they are even fast enough to decode it?

[Nezaara]

My drivers are from intel, not windows update. I'll see if there are any new ones since the last time I looked (less than a month ago). I will also continue this discussion in the QS thread, as requested, since this one is giant enough already.

[ionutm80]

Hello Nevcairiel,

I've recently had a inquiry with Egur on the usage of QS in LAV decoder with WMC7 (I could not have full-screen image in WMC7 with QS+LAV video only if I reduce a little the window from top right icon) and here it's his answer:

"Regarding LAV+QS:
MCE is special player with respect that it's the only player that works in Direct3D full screen exclusive mode. This special mode (usually found in games) do not allow creation of DXVA/D3D HW devices unless very specific conditions occur. When LAV decoder queries the QS decoder if it can play the movie, QS will return that it can't (can't create a HW device). FFDShow ignores this check (my ugly patch so MCE would work). Actual HW device is created after the renderer is connected, later on in the initialization flow."

Do you plan to change LAV decoder so that we can use QS properly with WMC7?

Thanks in advance for your answer,

Kind Regards,

IM

I think it'll still be a ways off Sexus, it's fairly low priority for him and he's taking a bit of a break right now.. Hopefully before the end of the year he'll get around to that and maybe knock one or two other things off his issues list as well ;)

Wonder what kind of CPU he has if 0.6% correlates to 60-90% on his computer. Intel486?

Apparently you don't know very-much about computers.

What I'm seeing here is like asking someone for money, and then insulting them if they don't give you the exact amount you asked for. It's just rude and ungrateful.

That was just your groundless opinion, of course.

What's more surprising is that someone actually cares about ALS which has had essentially 0 consumer or industry interest.

Does that mean you are going to ask the ffmpeg team to remove the MPEG-4 ALS decoder from their source-code ?

did you know that you can reencode your als to flac losslessly ?

Quite off-topic and unhelpful, to say the least.

/you added in my Ignore List.

No, because I'm not a friend of yours.

Please ignore the provocation and let me handle this.

[kitame]

What makes you think they are even fast enough to decode it?

i dunno, no solid proof but people have claimed that they have manage to play 720p Hi10P with a fair amount of bitrate stably and smooth. and since their IGP is running idle would mean it'll have a slim chance of managing 1080p as well if the process were to be partly offloaded into the GPU.

anyway it was a fair stupid question and i was just trying my luck.


also, i seem to have stumbled upon some issues, i dont know if its caused by LAVs but anyway, whenever i open a video the whole player sometimes freezes for a few seconds and plays normally afterwards. it rarely occurs but its kinda annoying.

setup:

@nevcairiel: Would it be possible to fix FPS detection for DVB broadcast? I'm using LAVF + MPC-HC and LAV Video Decoder reports wrong framerate. Everything is fine until we change audio track. A/V is out of sync. LAV Audio Decoder + ffdshow Video Decoder or MS DTV-DVD Video Decoder works fine. That's why I think it's LAV Video Decoder issue and I guess it may be framerate.

It work fine with recorded files, but I guess framerate is reported by splitter.

[ryrynz]

I dont know if its caused by LAVs but anyway, whenever i open a video the whole player sometimes freezes for a few seconds and plays normally afterwards.


Nobody here has had any issues like that, I would recommend changing your video decoder, splitter, renderer and media player one at a time just to try and narrow it down, it could be anything at this point.

[woody777]

I've got a question:

I'm trying to get Lav Splitter, Lav Audio, and Lav Video to work in WMC using Shark007. I know, I know... but, WMC is sooooo easy for my wife and kids to use. When I open a MKV, everything works great except VobSub never opens. If I open the same MKV in Graphstudio, everything works perfectly. VobSub opens (although it opens four times???) and forced subs are played as expected. I know you don't offer support for WMC or Shark codecs, but any help would be greatly appreciated!
