LAV Filters - DirectShow Media Splitter and Decoders

[madshi]

Don't remember any playback probs here at all, of course after an eac3to -> MKV remux.

Thanks, I got a demo DTS blu-ray though, but I'm having the trouble with a DTS-HD MA 2.0 disc. If I remux to mkv then I get different results. If the DTS-HD MA 2.0 is the only track, the Arcsoft decoder loads and everything is seemingly fine, though I'm muxing another one with several tracks to check again.

[nevcairiel]

btw, if there are multiple tracks, LAV Splitter will always try to pre-select the one with the most channels, as i consider more channels = more better.

[Andy o]

OK, so with mkv it's apparently working fine. If I open the m2ts then I get the PDVD8 decoder in addition to the Arcsoft one, and silence. I tried the dll from TMT5 too.

Nev, which bugs did the TMT5 decoder addressed compared to the one in TMT3? So far I can't tell a difference.

[nevcairiel]

Can you post the output media types of LAV Splitter Audio Pin for both MKV and m2ts for comparison?

[Andy o]

btw, if there are multiple tracks, LAV Splitter will always try to pre-select the one with the most channels, as i consider more channels = more better.

With the mkv, it does select the 2.0 MA track as default, where there is a 5.1 DD track (last one).

[nevcairiel]

With the mkv, it does select the 2.0 MA track as default, where there is a 5.1 DD track (last one).

well it would do that if its constrained by your preferred languages, or the MKV has a default flag on the 2.0 track.

[Andy o]

Holy crap must be the coffee. My mistake, it wasn't using LAVF for the m2ts. With the m2ts, it does select the 5.1 DD track first, as you say, but not with the mkv. Maybe makeMKV sets the first track as default.

So I'm back at square one. My receiver probably doesn't decode DTS-HD MA 2.0.

[nevcairiel]

Maybe makeMKV sets the first track as default.

There would be a "[default]" after the stream name/codec info in the stream selector if it does.

Nev

It's possible to class all audio 5.1 in first and the stereo in last ?

[nevcairiel]

Reordering them is more complicated then one might think - now they directly correspond to the stream index that ffmpeg assigns them. So, not really planned to change the order.

[ney2x]

Please ask clsid to add support for LAV CUVID and LAV Splitter/Audio in his Win7DSFilterTweaker. Many thanks!

Status on Bitstreaming:

AC3 works, E-AC3 works, TrueHD works, DTS works (even core DTS out of DTS-HD) -- just DTS-HD missing, i need to invent some smart way to detect DTS-HD, so i can switch the mode.

FWIW, E-AC3 never worked for me with ffdshow, so i guess this is good.

PS:
Everything only tested with LAV Splitter as source, and on my NVIDIA GTS 450.

[SamuriHL]

Oh damn, seriously?! :D SWEET! Cause I'm having *MASSIVE* problems right now. :( I ripped my Fast and Furious HD DVD to MKV this morning and am watching it now. ArcSoft Audio Decoder didn't bother decoding it (um, what?) so I added LAV Audio. Audio is going out of sync badly. Also something broke madVR exclusive mode while playing this one. Not having the best of days apparently. However, I definitely wanna try this out. Is this implemented in LAV Audio as you said it would be?

EDIT: I take it the code isn't checked in yet. ;)

[Sebastiii]

Trop cool :)
Sorry :) very awesome :)

[nevcairiel]

DTS-HD should work now too.
I guarantee for nothing, however. :p

Its all been checked in the repository as well, be sure to rebuild ffmpeg with my scripts, so it gets the spdif muxer which was disabled before.

If DTS-HD muxing fails, it'll fallback to DTS, this can happen on *very* high bitrate DTS-HD MA streams, although i'm not sure those appear on Blu-rays.

And yes, its in LAV Audio.

Like i said before, only tested against ReClock, my NVIDIA GTS 450, my Onkyo receiver, and of course with LAV Splitter. It'll quite possibly fail with other source filters because of wrong frame packing.

[SamuriHL]

Thanks, Nev. Gonna test your build now while I build my own. I'll get back to you shortly. :D

[nevcairiel]

I should cook dinner and then watch some movie while testing the bitstreaming... mm.. sounds like a plan.

[SamuriHL]

HOLY *********************. Andy! He bitstreams DDP on AMD!!! Nev, this is AMAZING! You have NO IDEA how kuel this is for us! Thank you SO MUCH FOR DOING THIS!!!

[SamuriHL]

DTS-HD MA not working. Flashing between DTS-HD MA and PCM on the receiver. No audio.

[nevcairiel]

DD+ is just broken in ffdshow, there is no hardware limitation.


DTS-HD MA not working. Flashing between DTS-HD MA and PCM on the receiver. No audio.

Does DTS itself work, from the same stream?

[SamuriHL]

DD+ is just broken in ffdshow, there is no hardware limitation.


Someone told us that on the ffdshow hd audio thread, but, we were skeptical. However, this proves it. VERY VERY kuel!


Does DTS itself work, from the same stream?

Will check in a minute. I went to play a TrueHD file after that and it crashed my machine. Rebooting now. Retesting momentarily.

[SamuriHL]

TrueHD works fine. DTS core works, as well from the same file that wasn't working with DTS-HD MA. So it's just DTS-HD MA that has the problem.

[SamuriHL]

Nice to see the forum back. sigh. :) Anything I can do to help with the DTS-HD MA bitstreaming issue?

[nevcairiel]

DTS-HD MA works fine for me. Does it no work on any disc?

I tried, for example, on the m2ts version of this:
http://www.avsforum.com/avs-vb/showthread.php?t=1330124

[nevcairiel]

Also, as before, attach debugger on a debug build. :)

[noee]

This is cool. Very cool. But, for bitstreaming these compressed formats, don't you have to run your monitor at the exact (or exact multiple) of the movie fps?

[VipZ]

Awesome Nev :)

Here are my findings, with Direct Sound renderer

MKV, DTS/DTSHD: Only work with AVI<->AC3/DTS between LAV Splitter and Audio
MKV, DTS-ES Matrix: 1st time I see this on AVR :)
Bluray (Eagle Eye), TrueHD,: Cant connect to audio renderer
M2TS (Sample posted earlier), TrueHD: Works fine
MKV,DD: Working fine.
MPEG-TS,DD: Most crash on start when bitstreaming, normal decoding ok.

If you need me to test anything let me know

[nevcairiel]

This is cool. Very cool. But, for bitstreaming these compressed formats, don't you have to run your monitor at the exact (or exact multiple) of the movie fps?

Thats not important. The only thing you CANNOT do when bitstreaming is let ReClock adjust the video speed to match refres rate, because then it goes out of sync. So with perfect bitstreaming, you'll end up with not 100% perfect video, because it could drop or repeat frames to match the refresh rate.

So, i guess, yes. For 100% perfect audio and video, with bitstreaming, it needs to be a exact multiple of the fps.



MKV, DTS/DTSHD: Only work with AVI<->AC3/DTS between LAV Splitter and Audio

That doesn't make any sense, the connection between LAV Splitter and LAV Audio should always work - unless you turned one of the formats off in the config.

[SamuriHL]

Gonna build it now. It works for nVidia, not AMD. :( Need to try something first to see if makes any difference. Nope...I took ReClock out of the mix. Same deal. Ok, building a debug version.

[VipZ]

That doesn't make any sense, the connection between LAV Splitter and LAV Audio should always work - unless you turned one of the formats off in the config.

If I bitstream, that filter gets put in the chain automatically, if I decode, it doesn't.

Any chance to add support in LAVF audio decoder to be able to connect with MS DVD navigator ?

[SamuriHL]

@nevcairiel:

Is that why I can't select it for DVD's in MC16?

[nevcairiel]

If I bitstream, that filter gets put in the chain automatically, if I decode, it doesn't.

That media type looks just perfect, i wouldn't know why it adds that weird filter there. o.O
The only thing that would make it break would be a sample rate of 0 in the media type.

Especially the only when bitstreaming .. that doesn't make any sense. I also cannot reproduce it here.

[SamuriHL]

Uhhhhh, Nev? This seems bad man. So, I fully removed ReClock from the chain this time (forgot I had it set to always load...sigh). On my AMD equipment, LAV Audio is no longer used for DTS at ALL unless I uncheck the DTS-HD MA bitstreaming checkbox. Then it'll do DTS bitstreaming. If I leave DTS-HD MA checked, it falls back to other decoders. Hell, I uninstalled ffdshow completely, unregistered the ArcSoft audio decoder, and it fell back to the microsoft decoder for DTS! So, something's wrong.

[nevcairiel]

It doesn't even work anymore if you disable bitstreaming at all?

Also, please post the output media type of ffdshow while bitstreaming DTS-HD MA.

[SamuriHL]

Oh sure now that I uninstalled ffdshow. :D Give me a few minutes as I just got the debug version built and installed. I'm saying that if I uncheck the DTS-HD MA bitstream option, then LAV Audio accepts the connection, however. Even if I leave the core DTS bitstream option checked. I'm saying that if I have the DTS-HD MA bitstream option checked, LAV Audio refuses the connection and it goes to another decoder instead. How whacked is that?

[VipZ]

On my AMD equipment, LAV Audio is no longer used for DTS at ALL unless I uncheck the DTS-HD MA bitstreaming checkbox.

This is exactly my issue, the AVI<->AC3/DTS filter doesn't appear if I deselect DTS-HD decoding. So I assume yours isn't working because AVI<->AC3/DTS isn't getting loaded.

[hoborg]

May be stupid, but can be this caused by registry prefered decoder selection under Win7?

[SamuriHL]

http://pastebin.com/download.php?i=BNcdzP9K

Please take a look at that. Especially line 7 [dca @ blah blah blah] Stream with high frequency...

Could that be why it's not accepting it?

[SamuriHL]

May be stupid, but can be this caused by registry prefered decoder selection under Win7?

No because ffdshow audio works just fine. Well, did until I uninstalled it. :D

[nevcairiel]

Do you have in ffdshow the "Connect as PCM first" checked? If so, what happens if you uncheck it?

It simply looks like the renderer doesnt want to accept a connection for 192000Hz at 8 channels and 16bit. (Basically how DTS-HD looks)

The AVI->AC3/DTS filter there changes the media type to actually be 2 channels, for some reason, that would potentially make it work then.

[Thunderbolt8]

I have difficulties with my inbuilt .ass subtitles again after reinstalling windows. it seems like that the inbuilt subtitle renderer of mpc-hc is always used and not directvobsub, even though the symbol loads up properly, because the subs looks a bit smeared and not really in focus (also am using madvr). I have the directvobsub and also the directvobsub (auto-loading version) directshow filter both set to prefer under external filters. but it seems like thats not enough.
so what am I missing?

I always disabled this option, had AC3 bitstream issues with it enabled.

That setting makes no difference at all in ffdshow for me. Works fine either way. I don't have a debug version of ffdshow built right now and they made some change to the repository that's causing me checkout issues at the moment. I don't remember the media types that ffdshow uses for bitstreaming DTS-HD MA off the top of my head.

EDIT: AH, there you go, the info you're looking for from ffdshow is above my post.
