AAC-HE and Matroska: is it possible?

[DamnedSoul]

i want to know if muxing an AAC-HE file created with besweet 1.5b22 (bsn rulez) and nero's dll version 6.0.0.11 into mkv is possible. i make some test but if i try to mux aac-he file into matroska, the central channel of my 5.1 file goes to the others channel :mad: . if i mux an aac-lc it's all ok.

someone could help me?

i used mkvtoolnix 0.7.2, matroskaplayback pack 0.6, matrixmixer 0.30b

sorry for bad english, but this is my best :p

Welcome to the forums. Please post your commandline used. If you had read the mkvmerge documentation, you'd find that when muxing a HE AAC you need to use the switch --aac-is-sbr, which tells mkvmerge that the AAC is HE. I don't know if this is causing your center channel problem, but since you said LC works fine, it's worth a shot. By the way, why are you using matrix mixer if your AAC is 5.1 ?

[Tuning]

Make sure you are using 6chold switch.Or in Oagmachine select 5.1(old).

thanks for your reply. I forgot this particular :rolleyes: , i always used the "--aac-is-sbr 0" command when i trying to mux an aac-he file.

i use matrix mixer because someone say me if i want to hear aac file i must install the matrix mixer (and coreaac decoder too). I must disinstall it(the matrix mixer)?

[DamnedSoul]

this is the command for creating aac file:

BeSweet -core( -input C:\AIita.ac3 -output C:\aacAI.mp4 -logfilea "d:\BeSweet.log" ) -azid( --maximize -c normal ) -azid( -oc,l,r,sl,sr,lfe ) -bsn( -6chold )

and this is the command for muxing it into matroska

\mkvtoolnix-0.7.2>mkvmerge.exe -o "d:\AI\provazza.mkv"
"d:\AI\4.avi" "c:\aacAI.aac" --sync 0:-88 --aac-is-sbr 0

welcome to doom9, DamnedSoul

try to mux directly from the .mp4 (without the aac-is-sbr switch) in mkvmerge - it isnt necessary anymore to demux to .aac first...

[tiki4]

And also the channel re-ordering switch in the -azid() section of the BeSweet command line isn't necessary anymore. Just use -bsn( -6chold ) for Nero <= 6.0.0.11 and -bsn( -6chnew ) for Nero >= 6.0.0.15. The rest is done by BeSweet automatically.

i have tried what you have suggested and this is the result:

(coreaac decoder properties)
AAC+SBR
24000 -> 48000 hz
6 -> 6

thanks a lot for your help, now i will use ONLY matroska (and aac too) for my rip :p

i want to know how to playback this type of mkv(he-aac+xvid)

sorry,i'm a newbie,and my english poor

[tiki4]

You need the Matroska Splitter filter from here (http://www.sf.net/projects/guliverkli). And also the Core AAC DirectShow filter from the end of this thread (http://www.hydrogenaudio.org/index.php?showtopic=6428&) in the HydrogenAudio forums. Unpack the filter somewhere on your system and register each of them with the following command line:

regsvr32 MatroskaSplitter.ax
regsvr32 CoreAAC.ax

Enjoy!

I was wondering if there are any other player than MPC 6468 which can play MKV+ACC HE?

Ive tried with zoomplayer pro/wmp6.4/older ver of MPC than 6468 and none of them works. Thx

[Tuning]

Every DSplayer with correct directshow filter installed can play MKV with He-AAC.For instance i use WMP9& 6.4 with installed,3ivX codec(3ivX splitter required),CoreAAC DS filter matroska playback pack.

[K-Dash]

Thx again.

Interresting, I just dl the Matroska Playback pack and tried to play it with wmp6.4 and zoom pro and it still didnt work. And I alredy have 3ivx splitter installed, so it could be that i need a reboot. I'll post the result after o reboot.

EDIT: 1

[Atamido]

If you installed any of the packs then you will need to go install the latest Matroska Splitter (http://cvs.corecodec.org/cgi-bin/viewcvs.cgi/*checkout*/matroska/doc/website/downloads/windows.html) because none of the packs have been updated with it.

Sorry for not letting u know Pamel, but I've had an ongoing discussion with Tuning on "Audio Thread" where I listed what Im using atm etc. Anyways to put this short; Im currently using the latest matroska splitter matroskasplitter_20031109.zip and coreacc + MPC 6468.
