LAV Filters - DirectShow Media Splitter and Decoders - Page 57

This 200mb sample is out of sync when played with lav audio decoder:
http://www.megaupload.com/?d=HFYOGAB5

It has flac audio, and I was using lav splitter as well.

also, did you take a look at the really large sample i sent you?

Playing around with LAVAudio and I can't figure out how to properly setup the channel mapping to downmix 5.1 to stereo...

With this setup I hear no voices: FL->1, FR->2, FC->1,2, LF->1,2. Obviously, I'm doing something fundamentally wrong...

Edit: Front Center needs to be mapped to channel 3 otherwise it never gets outputted.

You're playing in the code?
The channel mapping tables do not support mixing, if one number is encountered twice, the previous channel is being overwritten.

Sorry for the confusion! I was talking about MPC's audio switcher.
I realized that I don't need to enable custom mapping at all. It sounds the same either way.

nevcairiel - is there any chance you could add thumbnail extraction to your splitter? Seeing as haali removed it from his, and i do not like to have to use DivX to do the thumbs, if possible i would like to stay away from MF altogether.

Under linux there is a program called ffmpegthumbnailer, that i used to make the thumbs for all my videos, looks like it could be used on windows too.

There is one mkv i did that causes exporer.exe to have fits when it tries to make a thumbnail for it, yet under Linux it was fine.

Would be a nice feature, but i understand if you would prefer not to add it.

I've noticed the same thing. It only happens with LAV Audio and FLAC tracks.

if you using directsound as your audio renderer, it will automatically downmix things to whatever windows is configured for.

I've mentioned some of this earlier without response so I'll give it a try again.
Is it intentional that LPCM tracks doesn't connect to either ffdshow and/or MPC-HCs filter (VOBs)?
I also have a few MKVs that loads but doesn't play/show any frame at all (MPC-HC), are compressed headers etc fully supported?
It would also be nice if you could set file types to handle instead of all or nothing since a few features are lacking for at least Matroska such as embedded fonts and compatibilty issues.
I highly appreciate the work going into this project.

does DTS mean HD audio like DTS-HD MA works as well?

and are 2in1 .mkv movie version supported? (those which are originally seamless branching BDs and now work with chapters when being remuxed)

In the Splitter it works just fine, in the audio decoder only the DTS Core will be decoded, not the HD extensions.

Not yet, no.

@nevcairiel
Since you are working on the splitter, would you please look into the sync problems of LAV Audio when playing movies with FLAC tracks?
I do a lot of remuxes to FLAC and have a lot of movies with this problem.

Thanks

Nuno

nevcairiel · 28th March 2011, 18:23

I don't see the relation between working on the splitter and fixing audio decoder bugs, but okay!
In any case, there are several good FLAC decoders around, and you can configure formats now in LAV Audio .. i'm not exactly sure when i'm going to have time to look into it. I recommend madFlac

I'm sorry.
I just thought that since LAV Audio is part of the LAV Splitter, that you could look into it.
And yes, madFLAC is a great decoder, and this bug is not urgent. Just a reminder.

Do you have a a bug tracker I could fill for this LAV Audio issue?

Just out of curiousity, what's keeping this splitter from being added to MPC-HC right now?

jmone · 29th March 2011, 09:42

Hi nevcairiel, thinking outloud with the BD splitter, I understand we will at some point be able to select a playlist (from the mpls) but is there any meta data available to say what each playlist is? Eg. Is there any data in the mpls that will let you display that a particular playlist is say the Std or Extended play etc?

No.
You can get the length, though, which should give you some hints.
They do not contain such data because it usually relys on menus to navigate.

jmone · 29th March 2011, 09:59

True - makes "alternative endings" a tough guess however (but we can not have everything!)

jmone · 29th March 2011, 10:00

mmmm does the order in the mpls give any clues - eg is the "first" of the longer playlists the "std" one, the second the "alternative ending" etc or is this a very long bow to draw do you think?

nevcairiel · 29th March 2011, 10:33

I don't think you can really rely on that.

jmone · 29th March 2011, 11:03

I guess we will test and see all in good time
