MP4Creator creates ISO MPEG-4 (MP4) streams from (AAC) and/or video (MP4V,DIVX) compliant streams.


I thought VQF and AAC were going to be combined to create the MPEG-4 standard correct? Am I misunderstanding?

MPEG-4 standard supports AAC and TwinVQ as "general audio" profile - however, TwinVQ is not used anywhere in the "real world" as MPEG-4 profile..

Implementing a TwinVQ decoder would require MPEG-4 TwinVQ code (that is not hard to find) - but there is not a single MPEG-4 TwinVQ encoder available (except FhG MPEG-4 encoder that supports TwinVQ, but that encoder is in 'top-secret' state)

Also, MPEG-4 TwinVQ file format is different from .VQF format found on the Internet.

Well seems you are not getting any answers on this from anyone. So...

If you build MPEG-4 decoding within the PowerDivX Player you will be liable to pay MPEGLA a licensing fee for doing so. Further more MPEG-4 decoding must comply to a specific 'profile' or ye' shall feel thy wrath of MPEGLA for being a bad boy.

A work around is to allow the playback of MPEG-4 streams through a plugin in PowerDivX. Or for scientific purposes create a project on PowerDivX.com for a GPL MPEG-4 'simple profile' playback plugin and do not distribute the compiled binaries.

Sounds like XviD ;-) sorry Prof and -N ;-)

everwicked, I got it to work.

Well on Linux anyway. Just download the source from the project website and compile. Also comes with some tools to strip raw video and sound from avis. Don't know about muxing Ogg Vorbis though. Maybe you can figure that out.

I'll get back to you ASAP.

A guy called TheMaxx just mailed me a set of MP4 tools that, according to him, works with DivX. I didn't test it though.

It's in my page. Programs -> Others -> Set of MPEG4 Tools.

Regards;

Roberto.

Obs: It's compiled with VS.Net so, if you have some problems regarding .Net components, mail me, and I'll contact TheMaxx. Maybe he can provide me the sources, then I'll compile it with VC6.


Edit: And, just to make everybody even happier, I'm adding latest Psytel AACenc, V. 2.11.
Ivan, does this version takes care of the slider issues in Winamp?

Yes, it does

Don't use Philips player! This thing is hardly compatible with itself - it can only read Philips .mp4 files, and it won't accept other files (including conformance MP4 files from the official MPEG FTP server)

Better thing is to use Envivio TV:

http://www.envivio.com/solutions/etv/

Current version (v1.0) is not able to read MP4 files with PsyTEL AAC streams, but upcoming version (v1.1) will be able to read them (I have beta version of the new player, and it works properly)

The best option is MPEG4IP's mp4player, because it reads Philips, Envivio, PsyTEL and many other files - too bad it doesn't have GUI. Someone really should integrate it into GUI player or make DirectShow filter out of it.

Where can I download a copy of the beta version of the Envivio player?  The MPEG4IP player looks so unattractive.

One more question, does anybody know how to use MP4CREATOR.  I have a raw divx file and an aac file encoded with FAAC and I downloaded mp4creator60.exe from http://www.inf.ufpr.br/~rja00/ .  I tried it and i kept getting an "atom size"-something error.  Can someone please help?
