LAV Filters - DirectShow Media Splitter and Decoders

[VipZ]

More reason for LAV Video :p

[Portioli]

"dtsdecoderdll.dll" of any build or tmt (even 5) or only TMT3.0185?

Nevcairel i think everybody is thankfull for that.

[nevcairiel]

I recommend TMT5, they finally fixed mono decoding in there. The dll version would be 1.1.0.8

[Portioli]

how we check this?

ok i found that

thanks

[Mercury_22]

I fixed it for now, will need some proper fix later.

Yes it's working now !:thanks:

[Mark_A_W]

- The ability to use the ArcSoft dtsdecoder directly through LAV Audio, just drop "dtsdecoderdll.dll" in the LAV Audio directory, and lean back for full DTS-HD enjoyment. On the LAV Audio status page, the ffmpeg decoder is called "dca", and the ArcSoft decoder is called "dts" (or postfixed with the profile), so you can see if its active.
.


I so owe you a beer. Thank you :)

This is really a big step forward - a one stop shop decoder (well, actually if you did a similar thing with madFlac it would be complete.)

If it's not using a directshow connection, does this mean I can use the version which will handle DTS-MA 6.1 with eac3to, and the 24 bit version with LAV Audio?

Or have you solved the 24bit issue with certain versions of dtsdecoder.dll?



I'm not sure of your future plans, but some tray icons would be handy :cool:

[SamuriHL]

Hell no! The next thing on the list should be title selection!!! :p Tray icons can come later. :D

[jmone]

Hell no! The next thing on the list should be title selection!!! :p Tray icons can come later. :D

I agree on both counts (in fact MC16 tries to turn off tray Icons to stop issues with them grabbing focus on some systems)

[SamuriHL]

(In case people don't get my humor, I of course know that Nev sets the priorities and that we are blessed with the work he's done. I in no way am suggesting that my "demand" is to be taken seriously. Nor am I delusional to think that my suggestion means jack ____. :) It's just a hope!)

To guys with ATI Radeon HD 5XXX series and Onkyo receivers........
Do you really see the http://img811.imageshack.us/img811/8278/clipboard02eo.png light on the receiver while playing DD+ streams?

Are you by any chance using the Realtek driver?

[Andy o]

Thanks for this new feature Nev!

the version which will handle DTS-MA 6.1 with eac3to, and the 24 bit version with LAV Audio?

Or have you solved the 24bit issue with certain versions of dtsdecoder.dll?

Mark can you expand on this? I've used the Arcsoft decoder from 3.185 successfully with DTS-HD MA 6.1, the only difference with TrueHD is that it outputs 7.1, which is just fine since the receiver would do the same thing when getting 6.1 channels (duplicate the back channel).

[ontherocks]

Are you by any chance using the Realtek driver?
Nope, the native ATI HDMI audio driver.

[renethx]

@nevcairiel

Can do the same thing for DdpDec71.dll for DD+? Just for the sake of completeness. DD+ 7.1 test file (http://www.avsforum.com/avs-vb/showthread.php?p=19354466#post19354466).

[Andy o]

That would be great, since DD+ decoding for me breaks as soon as I seek within the file.

[Andy o]

Nope, the native ATI HDMI audio driver.

Don't know what's wrong then. Does it work with any other players? Although I don't know of any other that will bitstream with ATI cards.

[jmone]

Andy sorry - forgot to report my test on the DD+ 7.1 file. I have no issues with playback, seeking etc using LAVAudio (only outputs 5.1 of course + I only have a 5.1 system anyway). Rock Solid for me.

[jmone]

...also I've a ton of DD+ stuff from all my HD-DVD discs and these also play fine (though all are 5.1, no 7.1) with LAVAudio doing the decoding.

[Andy o]

We're talking about the Arcsoft decoder though, which is the only one that can decode 7.1 DD+. I also have no trouble with LAV and ffdshow on 5.1 files. Could you try the Arcsoft one, btw? I'd appreciate if someone could tell me if it's not only my system.

[Andy o]

Oh I didn't notice that you have only a 5.1 system. I'm thinking decoding that 7.1 file with Arcsoft you should also be able to get my trouble. C and R channels swap, and the surrounds are silent, once you seek.

[jmone]

OK gave it a go and it really is broken. It was kinda hard to test on a 2.0 system but I watched the MC DSP Analyser. While the channel mapping seemed OK if you played it though, a seek really does break the channel mapping including the Center going to the Right and all the surrounds dropping out. If you need me to I can run it up on the 5.1 HTPC.

[jmone]

...while this issue will not impact me on a 5.1 system..... is there any 7.1 DD+ material anyway?

[Andy o]

Just that test, I guess, but like renethx said... for the sake of completeness :). It's really not practically important, at least for now (who knows if when broadcasters start using DD+ some of them won't use 7.1), but it's just been annoying me that apparently I'm the only one having this problem.

[jmone]

Well I can confirm it is not just you!

[whurlston]

And my Denon 988. Just got a new AVR though a Yamaha V867 and will see how that pans out.

DD+ bitstreaming works fine with my 5670 -> RX-V863 (no reclock). I haven't tested with my RX-A3000 though.

[jmone]

Nevcairiel, i read with interest on P143 your testing of containers / codecs especially the issues with MKV's produced using mkvmerge and DTS. Are there any issues with DD+ and LPCM in MKV (I see you tested on TS but not MKV)?

The reason I ask is I've still got to convert my old HD-DVD's to a more friendly format (most have DD+ but some have DTS-HD), and to date non of the GUI options grab me as ideal:
1) TS or BD Stucture (eg Clown_BD): Get to keep any subs in PGS but all DD+ will be converted to DTS or LPCM
2) MKV (eg AnotherEAC3toGUI): Uses mkvmerge and the GUI seem to want to convert both the DD+ track to something else and the PGS subs get converted to VOBSUB

This is a task I want to do once so thanks for the testing as I had no idea of the issues with mkvmerge!

[Andy o]

Well I can confirm it is not just you!

Thanks. I set up my PC for 5.1 and it's a bit different than 7.1. With 5.1 my right channel doesn't go to center, it goes to left surround!

[Andy o]

I'm getting static with DTS-HD MA 2.0 and the Arcsoft dll. The LAV decoder status says "dts" only. 5.1 and 7.1 work fine with LAV. The Arcsoft decoder does decode 2.0 OK.

This is an audio mka sample, it's the same with mkv videos.

I can also confirm, that under LAVAudio
1) Plays fine using avcodec
2) Plays static using dtsdecoderdll

The limitations were in the DirectShow component, and you're free to use whatever version of the decoder you want.

What issues with 6.1, btw? The latest version, 1.1.0.8, decodes 6.1 just fine, except that it double the back center to both back left and right (making it 7.1) - but me personally, since i dont have a back-center anyway, thats welcome. :p

Thats too much work for too little benefit. There is barely any 7.1 material, and its kinda alot of work to figure out how a dll works if you know nothing about it.

[Andy o]

Sorry, that sample is only DTS 2.0, there's another title with the same video but DTS-HD MA 2.0 audio so I mixed them up. The following sample (different one) is DTS-HD MA 2.0 with the surround flag on. This static problem also happens with this sample.

Also, bitstreaming this sample, people with Pioneer receivers can check if their receivers need a firmware update. Receivers like mine (VSX-01) and as new as the 2010 generation (VSX-21 and others) are reported to have this issue. This is rare audio, as far as I know only recently available with Criterion releases of older stereo movies. It's not the same as regular DTS-HD MA 2.0, which works correctly.

From memory, an early version would just ignore the 6th channel - at least in eac3to.

Doubling the back centre to make 7.1 is perfect.

What does 1.1.0.7 do?

[nevcairiel]

http://www.megaupload.com/?d=CSCFJ85R

Fixed. It still says only "dts", but so does LAV Splitter, are you sure its actually HD? :p

It decodes fine now, though. The problem was that the ArcSoft decoder is outputting 16-bit for that file, and that totally confused my code.

Edit: Your actual HD file works, too.

[Gleb Egorych]

nevcairiel, thanks for that great dts addition!

I have a question about TrueHD. LAV Audio requires TrueHD subtype from a splitter to decode TrueHD and LAV Splitter gives it. But Haali and Gabest splitters send TrueHD with AC3 subtypes and in this case LAV Audio decoding fails. Could you please fix this if it doesn't require a lot of rework?

TrueHD is *NOT* AC3, its not even related to it, i do not know how they ever came up with the idea to use the AC3 subtype. Use a splitter that actually knows how to deal with TrueHD, and you won't have those problems.
The only thing they have in common is that both are Dolby products...

It'll be fixed eventually, but not so soon.

Here is a 6.1 sample, at least the volume status page in LAV Audio shows audio coming out of the back channels (with 1.1.0.8), can't say about .7, feel free to try it.

OT and FYI - I leaning towards converting all my HD-DVD's to a BD stucture on the HDD (using Clown) and converting all DD+ tracks to LPCM. The results play perfectly with LAVSplitter/Decoder including Subs and Chapters with no transcoding issues for the Audio. The only downside is the extra space that LPCM takes up over DD+ but...it ain't that much anyway. The other "benefit" is you can then burn the structure to a BD disc if you need to play it back in a BD player.

[nevcairiel]

I dunno why it converts the Subs to VOBSUB, PGS is fine in MKV .. on another note, doesn't HD-DVD use extended VOBSUBs, and not PGS?

Anyhow, you could also use FLAC in MKV.

PS:
The DTS in MKV by mkvmerge "problem" isn't really a problem, its just not perfect.
I have been thinking about just turning the logic off for DTS in MKV, or at least relaxing it even more.

Not that it bothers me much, i think i have 2 actual MKVs with DTS-HD, i usually keep all my HD movies either as BD structure or just keep them on the BD disc. ;)

[jmone]

I was under the understanding the HD-DVD also used PGS but the format was a slightly different implementation and the clownBD calls BDSup2Sub (".sup" "/res:1080") to convert the extracted Subtitle.SUP file to one of a similar size that is then muxed back in.

[nevcairiel]

What i could find on the topic is that HD-DVD either uses default DVD VOBSUBs, or an extended version with more colors.

[jmone]

Yeah, don't know - but asked the Q over at the BDsup2sub thread - http://forum.doom9.org/showthread.php?p=1500776#post1500776

[madshi]

HD DVD (without a hyphen!) uses an extended version of DVD subtitles.

Stand corrected!

There are some compatibility issues between LAV Audio and standard AVI splitter. Tested on many AVI samples with MP3 tracks. After multiple seeks LAV Audio often needs a few seconds to resync with video. On one sample I even get crash after multiple seeks.

Unfortunately, the sample file is quite big.

If I use LAV Source as source filter and splitter then the problems don't occur.

[nevcairiel]

I cannot reproduce any problems with the default AVI splitter, sync seems fine instantly, no matter how often i seek. Unless you can produce one specific sample, there isn't anything i can do.
Besides, just use LAV. :)

PS:
Maybe the situation improved in my development version already, who knows.

[Mark_A_W]

Here is a 6.1 sample, at least the volume status page in LAV Audio shows audio coming out of the back channels (with 1.1.0.8), can't say about .7, feel free to try it.

http://www.multiupload.com/YML3MLBPYP


Interesting. The Splitter Filters confirms it's 7 channels (6.1), but watching the LAV Audio decoder levels meters, I'd swear it was 7.1.

It doesn't look to be just copying the two back channels, every surround channel seems to have a slightly different signal (unless the meters are misleading).

Whereas, if I play a 5.1 source, the side channels are inactive.


Anyway 1.1.0.7 works.

Funky video BTW ;)

[nevcairiel]

Interesting. The Splitter Filters confirms it's 7 channels (6.1), but watching the LAV Audio decoder levels meters, I'd swear it was 7.1.

Yeah, thats after decoding, of course, and the decoder creates 8.

Heh, someone posted that for another issue a while back.

[Mark_A_W]

Yeah, thats after decoding, of course, and the decoder creates 8.



I realise that. What was interesting was that it is performing some sort of processing to create the channels, not just copy the Centre Back channel to BR and BL.

Wish I could get ffdshow to do that for my FLAC 5.1 stuff...grrr...

[noee]

Nope, the native ATI HDMI audio driver.

Check the docs on your receiver. Even if it's not showing the DD+ symbol, it may still be receiving the format properly. Apparently, depending on DD+ input source, the DD and DD+ are treated the same, at least on Onkyo.

[Andy o]

Wish I could get ffdshow to do that for my FLAC 5.1 stuff...grrr...
Why not use DPLIIx for 5.1 content? I'm using it and it works fine.

[marconi]

I am reinstalling Win7 64 on my HTPC. When I use the version 0.25 x86/x64 LAV installer a message pops up asking me to install the x86 version of VC++2010 Runtime (the 64 bit version is already installed thanks to AMD Catalyst). In my last build I did this, but then ran into errors with AMD Catalyst when I upgraded the driver to 11.5. Any suggestions on how to proceed? Apart from the Catalyst errors, the LAV filters worked very well with MPC-HC.

[nlnl]

Thanks for LAV!

Still can not play dts hd ma 2.0 audio in mkv http://www.multiupload.com/FJ7YOCNC6M
MPC+LAV splitter+LAVaudio (bitstream) + system renderer= static noise when switching audio tracks
MPC+Halii+LAVaudio (bitstream) + system renderer= OK

And if I remux everything in .ts, I have the same issue.
