I'm interested in working with video in an MP4 container. I have a few questions.

What can i use to mux tracks together? Virtualdubmod doesn't seem to support it.

Is it safe to ogg audio in an mp4 container?

you can mux MP4 with 3ivx and GraphEdit


i think MP4 support only AAC and MP3
OGG in OGM

Doom9.org has a nice guide about mpeg-4 video/audio muxing.

It is possible, but it is not safe and definitely not a wise idea. MP4 players expect an AAC stream, at most an MP3 stream. Most of them won't play the audio if they find a vorbis stream there.

I suggest you check 3ivx muxer and their guides:http://www.3ivx.com/support/index.html

VirtualdubMod already supports editing of native MPEG4 MKV files, even with AAC audio. The only problem currently is that there is no transmuxer existing as of yet, allowing to put the streams from an MP4 into a MKV file, but Mosu is working on this already.

The reverse, to extract a MKV file after editing into a MP4 could be done already, if the 3ivX guys will cooperate with us and add a nother MEDIASUBTYPE to the allowed input nodes of their MP4 muxer ...... no big deal, we will talk to them after we have the MP4 --> MKV transmuxing working .....

QuickTime does a decent job in editing MPEG-4 files. I know Windows users don't like it, but it works Since MP4 is based on the QuickTime file format, that's the answer to your MOV-in-MP4 question. However, there aren't many reasons to use MOV on Windows...

What questions ? You are aware i was talking about MKV ( = matroska ), and not MOV ?

quicktime cant handle advanced simple profile content in mp4

Yes, and that wasn't really what I was (trying to) answer. What I meant was that the answer to "Is it safe to ogg audio in an mp4 container?" is that's what MOV is for.

Anyway, if you install 3ivx, QuickTime will happily play advanced streaming profile MP4s, as long as they don't have N-VOP frames (according to 3ivx). I don't know whether they released a QuickTime component for Windows, though.

nope, it will only work with .mov not with .mp4

Wrong

and you are sure that sorenson/3ivx produce advanced simple profile and not only simple profile?

in my test with xvid (qpel, b-frames) it didnt work, and i also have this info from the 3ivx guys themselves

btw: rjamorim, did you get my mail?

and you are sure that this specific sample is advanced simple profile

if yes, than i wonder why qt doesnt handle xvid in mp4

>_<

well thats not an answer

when muxing xvid or divx5 into .mp4 with 3ivx these files should be 100% spec compliant mp4 files, but qt doesnt handle them (with qpel and b-frames)...

and did you get my mail?

I did. Sorry, was too busy with RRW these last few days. I will upload it to RW ASAP.

ok, no need to hurry

The only advanced simple profile in 3ivx D4.1 is MPEG Quantisation, the rest have been disabled.

EDIT: Oops, that's a screenshot of Sorensen... silly me...

Actually, he's right

3ivx can decode ASP, but the QuickTime MP4 parser will not parse ASP

Ergo, the decoder can't decode ASP MP4s inside QuickTime.

movs are completely unlimited

i have done it. i encoded a file w/xvid, and B-frames. and QT will play the resultant .mp4 file.

Heh. Same here. I encoded a file with Sorenson + B-frames + Qpel, and QT played it.

hm i have done it too
xvid with 2 b-frames and qpel

perhaps its the qpel, perhaps the 2 bvops that make it not work?

ok i now tried it myself with this settings (2 b-frames, qpel) + mp4 container (!) and the latest quicktime doesnt play it

i get a "this file uses technologies quicktime doesnt support" error message

Just to make sure: You are using 3ivX decoder?

you might also try the ffusion component

i tried both with and without 3ivx, i also tried the enviviotv qt plugin

still qt blocks the file right from the beginning ("technology not supported")


which tool (version) exactly did you use to encode the file?

Sorenson Squeeze 3.0

I won't remember the exact settings though.

hm i tested it with Sorenson Squeeze 3.5 (Sorenson Video 3.1)
