How to Extract / Demux AAC from MP4

[kilg0r3]

Hi,

I encoded some files to AAC using the besweet-nero combo. Now nero outputs mp4 files, and, even if I choose export AAC it AFAIK, it does not write a native / raw AAC file. Thus I now have three MP4 Files I'd like to mux with a video stream but mp4ui does not support muxing MP4 into MP4. I even tried to it in graphedit using something like three asynchronous file sources, two 3ivx splitters, one 3ivx muxer and one filewriter. The result was a very large file :D, off which the 3ivx splitter can play only the first audiotrack :(.

Ah forgot to mention that one track is LC-AAC (48000Khz) and the other two are He-AAC (22000Khz). Don't know if I am actually supposed to expect that it would work ;)

Thanks in advance.

BTW: What is your faourite MP4 video plus multiple audio tracks processing chain?

Try GPac MP4Box ( http://www.rarewares.org/mp4.html )
In a .bat file write something like :
Mp4Box.exe -raw TrackID Yourfile.mp4
You will find TrackID opening Yourfile.mp4 in MP4UI or with :
MP4Box -info Yourfile.mp4 >INFOaboutYourfile.txt
I hope it works.:)
Greetings,
Springl

[kilg0r3]

Thank you springl!

But, thank :angry: you Ahead.

The problem with only one stream showing up was due to the Nero Digital Parser filter pushin itself in. It functions as file source filter and - wonder what- it lets out only one stream. First thing I did after this discovery was to unregister _all_ nero digital filters. Don't need them any way.

Thank you Radlight team for your great filter manager, and this time I mean it!

Hi kilg0r3,

I know what you mean. If you had used dBpowerAMP or Foobar2000 you are given the following output options: -

AAC in .mp4
raw .aac
raw .aac and AAC in .mp4 streams at the same time

When wanting to mux several AAC streams/tracks with MP4UI, I normally generate 1no AAC in MP4 stream and the rest as raw .aac streams.

I then use MP4UI to open the AAC in .mp4 file and then use the 'import' button to 'import' the raw .aac streams

I did a test not so long ago and muxed around 20 tracks into the one .mp4 file, I then changed the file extension to .m4a

The files work really well in MPC and Nero's ShowTime player.

Does that lot make any sense?


Cheers


EDIT: And yes, mixed AAC-HE and LC streams work in the same container. If you mux an AAC-HE stream into the container first and the rest as any other combination, Nero's ShowTime player will even display the correct AAC info tag in the player!

Whoaha!

The files work really well in MPC and Nero's ShowTime player. I know it may sound a little bit 'orthodox' but I don't think I will ever use Nero's Player or any other specific player just to be able to play a specific file type. Afterall MP4 is supposed to provide interoperability.

BTW-1 there seems to be some incompatibility with Morgan Stream Switcher. When switching streams the playback jumps back to the beginning. With MPC internal stream switcher it works well. Sigh. :(

BTW-2 Do you know if the new Kiss players will support vorbis as soundtracks in Mp4 files or only as unmuxed soundfiles?

BT§-3 ther is somewhere a huge collection of Qs&As regarding the new Kiss modells, which was collected in an interview but I can't find it anymore. Any idea?

Afterall MP4 is supposed to provide interoperability. I actually find Nero's ShowTime Player quite useful. The new version (v1.5.0.22) is much improved. And providing you replace its video DSdecoder with this earlier version (http://www.SeeMoreDigital.net/Uploaded_Files/Doom9_Forum_files/Nero_DSFilter_Fix.zip) it's able to offer much better playback of 'anamorphic' AVI's.

Also, despite popular belief Nero's ShowTime can play just about any type of file going (provided the necessary filters are installed).

Rest assured my problem is now sorted, I've even managed to keep all Nero's filters!

kilg0r3, so after all it worked with muxing with 3ivx?

you can also merge two .mp4 streams with gpac's mp4box, without the need to go via .aac (which is bad for he-aac anyways, as the he-aac flag gets lost)

Sigh.morgan is evil, but yes not only mpc handles switching multiple audio .mp4 files, also bsplayer does it (dunno about zp or other players)

BTW-2 Do you know if the new Kiss players will support vorbis as soundtracks in Mp4 files or only as unmuxed soundfiles?i very much doubt it
you have to see it that way: .vob files are basically .mpg files
now the mpeg-2 standard (the same way as the mpeg-4 standard for .mp4) defines how to place non mpeg streams in .mpg, and the dvd specs make use of it and place ac3, dts and vobsub in .mpg
now you could also theoretically place vorbis in .mpg, but would you ever expect a player to handle this combination (apart from the fact that no muxer able to do this exists)? no! the same goes for vorbis in .mp4

But I have to mention that if you don't install 3ivX codecs at all but do install Nero's NeroVision Express (with video DS filter change) everything co-exists quite nicely - and with no expiry time out!

@ bond

1. nope didn't. I got stuttering hanging video.

2. There are patched versions of mpeg4ip to include vorbis in mp4, aren't there?

3. Ok. Pro's no tell me what are your favorite apps to do movie backups with multiple soundtracks?

1. nope didn't. I got stuttering hanging video.ah, did you mux from .aac files in graphedit
if yes, than you reproduced a known bug in the aac parser filter. i already reported this to the dev, never got an answer
you will have to mux from .mp4 when using aac streams

2. There are patched versions of mpeg4ip to include vorbis in mp4, aren't there?yes here (http://newserver.maersk-moller.net/projects/mpeg4ip/)
maybe kiss will support it if many ask for it, but i wouldnt think it will do by default

3. Ok. Pro's no tell me what are your favorite apps to do movie backups with multiple soundtracks?3ivx and mp4box (3ivx is maybe easier to use for multiple soundtracks)

[SeeMoreDigital]

Originally posted by kilg0r3
3. Ok. Pro's no tell me what are your favorite apps to do movie backups with multiple soundtracks? I use Foobar2000 to generate my 'primary' audio file as AAC in MP4. And all my 'other' audio files as ISO 13818-7 .aac

I then use MP4UI to mux.

Here a link to my How to... Use MP4UI (http://SeeMoreDigital.net/05_How_to..._Files/How_to..._Use_MP4UI/MP4UI.html) Guide

But this is obviously muxing. For de-muxing, I guess it's up to GraphEdit as MP4UI 1.0 beta2 and 3 are pants at doing this... some of the older versions faired better but not with Nero streams for some reason!

Erm, sorry guys, I allready changed subject. It's all about muxing and creating now.

So, you use mp4ui. Hm, I somehow had the feeling that this app is not to be trusted. Don't know how I came to this feeling though.

[kilg0r3]

Nope, gouged in stone :)

@ bond

yep, I muxed in graphedit.

And, I think it is a shame to abandon vorbis as sound format for the sound track, especially because the more recent derivates sound so good.

In the 3ivx muxer, do you keep all boxes checked?

[kilg0r3]

Hum, strange when i mux the video stream and one audio stream with 3ivx in Graphedit the resulting movie starts with a two-second freez.

When I mux with mp4ui, everything seems to work fine.

When I try ;) to use mp4box I always get an 'cannot find specified URL' error although the paths are triple checked.

Regarding mp4box, firstly, is there any definite advantage over the compiles of the mp4ip tools, and, secondly, how doe you actually mux more than one soundtrack and a videostream?

how doe you actually mux more than one soundtrack and a videostream?only via .bt i think, unless the -merge switch also works with more than 2 input files

Regarding mp4box, firstly, is there any definite advantage over the compiles of the mp4ip toolsyou mean apart from that mp4box will create 100% spec compliant .mp4 files for sure, in contrary to the risky mpeg4ip tools? ;)

MP4UI is still my prefered method of muxing. The MP4 encodes play very well in hardware via my Xcard!

The only downer is that the card can't detect more than one AAC audio stream but hopefully this will be rectified in the next driver release!

This time it was AAC in MP4 which I tried to mux. so there was no AAC parser filter invovlved.

Reagarding mp4box, the mp4 however may contain AAC, I strongly hopt. Otherwise, spec compliant or not, mp4box, then is pretty useless to me. I won't go back to mp3.

This would leave me with only 3ivx and mp4ui the latter of which is based on the 'rsiky' mpeg4ip tools, no? Or, perhaps I have to go and browse a bit through the MP4 FAQ . :rolleyes:

Edit: Post edited, misunderstanding regarding AAC and MP4Box removed. howerver too slow for bond :P

As I mentioned earlier I find MP4UI more than adequate and it has not crashed at all since I worked out how to use it properly.

No -merge eexplicitly does not support more than two streams total. Hum, I hadn't planned to learn somtehing like vrml just to back up a video, two or three audio streams. And, it will surely get even more complicated when trying to preserve subs und chapters.:eek:

[EDIT]
O.k., I manage d create a movie with two he-aac (in Mp4) streams using 3ivx multiplexer filter. The file plays o.k., only one of the audio streams 'has sound', that is, it is represented in the audio switcher dialog (MPC) but when I select it there s no sound. the relevant decoder filter also show no information about the stream on the property page.

To me this seems to be a problem of the splitter filter. Because in VideoLan Client there is no problem switching between audio streams.


@bond

Another question, you metioned that, when extracting a he-aac stream from mp4, the he-aac flag gets lost. does this mean that it will be decoded as lc-aac? And, when I use Nero to export an ISO-???? aac file, will it suffer from the same problem?

Hi, guys !
A bit late post, but it will help a bit, I hope.
I investigated this problem some times ago and found:
1. You can easly mux video and 2 (or 3 or whatever) audio streams with Graphedit and 3ivX filter set, but as bond mentioned, audio source should be mp4.
2. Problems coming when you try to play it.
I. If you need to play both track simultaneously (for example as do I - original track + mono translation) then the only choise is BSPlayer. But it does not work with 3ivX splitter. (Plays first stream only and sometimes carshes). There is no solution for it period. I've questioned it on 3ivX forum, but have no answer.
II. If you need to play one of the tracks. Use MPC (Media Player Classic). It works fine. Use internal stream switcher and all will be fine. Note, that CoreAAC (or internal aac filter, anyway) will show you incorrect stream information (i.e. full freq. for HE aac file, 2 channels for mono file) but plays stream right.
P.S. We discussed this with bond about 2 month ago and seems that nothing have changed period.
See: hydrogenaudio thread (http://www.hydrogenaudio.org/index.php?showtopic=20707&)
I hope it will solve your problems...

Missed this post, sorry.
Hmmm. I've used two HE aac streams for Equilibrium encoding. All worked fine... Try BSPlayer, playing only one of the streams. And check what is shown under Options->Filters->Advanced. BSPlayer was always more informative than MPC for me...

[malkion]

@Andrey

just for an experiment, have you ever tried to play multi audio tracks simultaneously with disabled morgan stream switcher on mpc?

[Andrey]

malkion: just for an experiment, have you ever tried to play multi audio tracks simultaneously with disabled morgan stream switcher on mpc?
No.
Hmm ? But how ?
When you select another track, mpc seems to switch to it, not add it to playing matrix...
So, am I missed something ?
P.S. I 've already asked how it is possible, but got no anwer ;)

But why would you want this facility anyway?


Cheers

[Andrey]

SeeMoreDigital: But why would you want this facility anyway?
You mean why to play two tracks together ?
This is useful when you have a mono translation file with the translation itself only. Then you can play original movie as is and add a translation, if you want...
malkion: disabled morgan stream switcher on mpc?
Oh. May be I get your point :) . Did you mean with all stream switchers (morgan and internal) disabled ?
No too, but I'll try...

Do you want is to be able to select say, the right channel but have the audio come out of both the left and right speakers. Or select the left channel and have the audio come out of both the left and right speakers?

I much prefer to be able to have totally separate audio switching, like we have with DVD!

If you need to play both track simultaneously (for example as do I - original track + mono translation) then the only choise is BSPlayer.no need to go with a player which was not able to switch audio streams and therefore played both together (the latest version already handles the switching correctly)

the mp4 container itself offers all you need for being able to play two streams simultaneously:
the feature can be called something like a "composition matrix" and, like i wrote in my mp4 faq already, allows all sorts of manipulation of the a/v streams on the container level, like rotation of the picture, ar storage on the container level (!) and much more, but also playing two audio streams simultaneously

as i am not someone who promotes "theoretical features" of course you can already make use of this practically:
you can author the mp4 this way already in apples quicktime under Movie -> Get Movie Properties -> Sound Track -> Volume
from what i read the volume value defines how much the two streams are mixed (1 means no mixing), but you will have to test it out yourself what would be the correct value for your purpose
i dunno whether the 3ivx splitter already makes use of these composition options stored on the container level, but quicktime definitely does already

anyone ever said that mp4 is not a powerful container ;)

[Andrey]

SeeMoreDigital: I much prefer to be able to have totally separate audio switching, like we have with DVD!
This is the best option, of course, but takes more space.
Especially if it is 5.1 sound - then you should store two 5.1 tracks, which takes a huge amount of space... :(

SeeMoreDigital: Or select the left channel and have the audio come out of both the left and right speakers?
For example, I have usual film stereo track. I 've create second stream with mono translation. When I play them both - I hear stereo sound from film and translation. By default windows system muxer mux mono track into both right and left channel, so the translation sound comes from both speakers, but w/o stereo phase positioning (w/o feeling the source is at center).
Very useful, really.
bond: (the latest version already handles the switching correctly)
Really ? I should test it, definitely !!!
Thanks for the info !
bond: anyone ever said that mp4 is not a powerful container
No doubt ! I like .mp4, the only problem with it is a lack of support, period...

[Andrey]

bond: (the latest version already handles the switching correctly)
Bingo !!!!!!!!!!!!!!!! :cool:
The BSPlayer now works with 3ivX splitter !!!
Yeah, now .mp4 is definitely my container of choise !!! :D

[kilg0r3]

did you try to play the file in bsplayer and graphedit? do they show all the streams?

Bsplayer does not work at all. It chokes on the file (not the latest version of bsplayer though). Graphedit shows all three streams and connects them to the proper decoders (1x Xvid, 2x CoreAAC) The Problem persists in Graphedit; one Audio stream is dead.



[Edit] Whoha! The latest version of Bsplayer seems to work, although it uses Morgan stream Switcher, which did neither work in Graphedit nor in MPC. Is there a way to disable MorganSS in BSPlayer. Just to test if the internal switcher can do it too.

Unfortunately BSPlayer has never been really stable on my system. We'll see. At least the muxing seems to have worked. :)

[SeeMoreDigital]

I've got a short test clip somewhere I made with MP4UI. It contains the following: -

1no anamorphic XviD video stream,
1No 6Ch AAC-HE audio stream
1No 2Ch AAC-LC audio stream
1No 2Ch AAC-HE audio stream

If it's useful to any of you guys I'll dig it out and make it available for download.

[kilg0r3]

Yep that would amke statements more comparable.

Updates:

3ivx Splitter seems to include a stream switcher cuase it is possible to select stream in MPC with Morgan SS uninstalled. However, then also one audio stream is playable.

Perhaps this is part of the problems on the DirectShow Platform. The switching facility in ogg DS has also been causing a number of problems.

When playing files created with mp4ui (as always 1 video 2 audio, one of which he-aac with lost he-aac flag) in VLC the second audio stream does not play too. It seems that the loss of the he-aac flag is a problem. Files muxed with 3ivx work. as stated above.

Perhaps this is part of the problems on the DirectShow Platform. The switching facility in ogg DS has also been causing a number of problems.the oggds splitter from tobias has a stream switcher inbuilt, in contrary to 3ivx

It seems that the loss of the he-aac flag is a problem. Files muxed with 3ivx work. as stated above.i doubt that the lost he-aac flag causes this. without the sbr flag the stream is simply a lc-aac stream with 22050hz, which shouldnt cause any problem on the player side, unless the player is buggy

[Andrey]

i think unreg mss is the only way to make bsplayer use its internal switcher
Yep. Think so.
BTW, I dislike mss (some times ago it crashed very often on my system) and now use only internal switchers of MPC and BSPlayer.
kilg0r3 - may be it mss that cause your problems ?
When playing files created with mp4ui (as always 1 video 2 audio, one of which he-aac with lost he-aac flag) in VLC the second audio stream does not play too.
Hmmm. I've heared, that things changed a lot from that time, but I switched to Graphedit and 3ivX filter set just because mp4ui sometimes produced incompartible output... May be the problem still exists ?
I did not have last mp4ui version, nor I would try it again in some time (the last time I spent half a day and w/o any result), so may be somebody who uses mp4ui quite often can check this ?

[kilg0r3]

Hrm, I am not sure whether you are right or not. I tried it again with MSSwitcher unregistered _and_ disabled internal switcher in MPC. The filter menu in MPC still gives the option to select streams via the 3ivx entry. Looks like this

www.netcologne.de/~nc-allgeife8/1.jpg

The entries are clickable. If you do nothing, you have two dots and you have sound. If you click the upper one the lower dot vanishes but I have still sound. If you click the lower one, the dot changes to the lower entry and the sound is gone.

[SeeMoreDigital]

Do you mean: -

http://www.netcologne.de/~nc-allgeife8/1.jpg

From personal experience, I got everything working fine using Nero's filters (you could even select audio tracks in Win Media Player). But then after installing 3ivX's filters everything went 'tits up'!

Unfortunately I found it impossible to go back!

Having said that, you need 3ivX's filters when using GraphEdit. So I don't know what the best solution is. Maybe MPC is trying to be too clever!
