It seems to work fine now...I'm testing fresh cvs builds from January 14th/16th and all seem to be ok.

I'll upload a build tonight for my part.

MP4Box crashes just after importing audio when using MeGUI 0.2.3.2024 as a frontend to mux a .264 with an AAC .mp4 audio file. When approximately will a working MP4Box be released and where is the best place to download it?

first of all what mp4box compile did you use?

Daniel Mott · 16th January 2006, 15:04

Sorry for not specifying! I used the latest one on this page:
http://www.aziendeassociate.it/cd.asp?dir=/gpac/dev (MP4Box - GPAC version 0.4.1-DEV)

Maybe there's a better place to download ready-compiled versions?

bond · 16th January 2006, 15:39

indeed, the compile available there is borked

celtic_druid has already made a new one today, which works fine
you will have to wait till it gets posted on that page

Great, thanks a lot! I was getting really eager to do some muxing...

Zero1 · 17th January 2006, 23:19

Hmm, just wondering if anyone else is interested in Variable Frame Rate MP4, by using MKV timecode files? (No, I'm not volunteering, unfortunately I can't program, otherwise I'd gladly help

)

There was a request put in a while ago but nothing as of yet.

The suggestion posted was that you would encode and mux your decimated video, and add the MKV timecode file at time of muxing and have MP4box alter the frame durations of the MP4 file (I'm assuming that's how it works, I recall the stts atom being mentioned).

I think it's a good idea since you will be able to use existing software to create VFR MP4, as long as the feature exists in MP4box.

The other thing I look forward to is reduced encoding times, you can decimate quite a lot of frames in anime, and encoding H.264 at high quality it really saves time as well as helps with playback requirements

bond · 17th January 2006, 23:42

Zero1:

there has been already a feature request for adding this timecode thingie to mp4box, with no response from jeanlf till now tough:
http://sourceforge.net/tracker/index...01&atid=571741

the next thing would be being able to demux vfr mkv to .mp4 with mkvextract, but mosu doesnt seem to be willing to do that

the next thing would be getting vfr output to work within x264. i am pretty sure the gpac lib already does vfr, so it would need to be added on the x264 side (frame dropping aso...)

Zero1 · 18th January 2006, 00:51

Hmm, I originally posted thinking that it had been added, seems it has not. That's a bit of a let down lol, but still, there's always the next day...

I'm having this same problem. If you use BeLight and check off "ISO AAC format" thing (.aac) then it will mux correctly.
Waiting for a new MP4Box compile.
Thanks to everybody who works hard compiling this stuff for lazy people who don't feel like figuring out how to use MinGW

Already done...check the link above.

btw, I found an other issue with -split command and chapters added during mux process.

Tested with a fresh cvs compile. This :

Code:

mp4box -split xxx -add video.mp4 -chap chapfile.txt output.mp4

Process works fine but chapters are lost (tested with MPC, VLC, and some other dshow players).

But with 2 steps all seems to work fine...

Code:

mp4box -add video.mp4 -chap chapfile.txt output.mp4
mp4box -split xxx output.mp4

A request: it could be great to centralize somewhere in a thread all bugs/issues that we have with mp4box.

no need for a thread that mp4box devs dont read anyways

all bugs should be collected in the gpac bug tracker available here:
http://sourceforge.net/tracker/?atid...01&func=browse

edit:
btw i dont see the chapter adding + split combination as a bug, its more a feature request imho

Kurtnoise · 23rd January 2006, 15:16

I remade my words. My request is more oriented for people here, to inform them...Think about fps switch for mp4 adds, ac3-in-mp4 no way, etc...

SeeMoreDigital · 23rd January 2006, 16:03

That was the original purpose behind this very thread

It's also why I included the, MP4Box "Request" Summary and MP4Box "Implemented" Summary boxes.

And from what I understand, Jean does visit here from time to time also.

Cheers

bond · 23rd January 2006, 19:06

hm i could add that to the mp4 faq sticky?

any idea what issues should be mentioned (next to the "specify the framerate when importing raw video" thingie)?

Varium · 31st January 2006, 23:39

Sorry, if this has been asked before, but I notice that when i use Yamb or Mp4box cli, that it fails to work unless the files I want to mux are in the same directory. I've tried all the Mp4box builds I can find and they all give the same problem.

"C:\Program Files\MeGUI\MP4Box.exe" -fps 23.976 -add "C:\Documents and Settings\Nile\Desktop\Beet The Vandel Buster #45_track1.h264" -fps 23.976 -add "C:\Documents and Settings\Nile\Desktop\Beet The Vandel Buster #45_track2.aac" "C:\Documents and Settings\Nile\Desktop\Beet The Vandel Buster #45_track1.mp4"
Done using MP4Box_20060119+pengvado-patch

Here are some screens, and an error log file

Before:

After Muxing attempt:

Kurtnoise · 1st February 2006, 11:59

mmh, strange. Works fine for me here with the same command line.

Try w/o -fps for both A/V files...and post somewhere some samples.

Varium · 1st February 2006, 17:57

I just tried it again, and I think it only crashes with filenames of a certain length. I'll post 2 copies of the sample with different names, to see if this is correct.

Varium · 1st February 2006, 18:47

Sample 1 contains a raw .264 stream, an aac file in an .mp4 container, and a succesfully muxed file. The filenames for the audio & video are short.

Sample 1

Sample 2 Contains the same audio & video file, except with longer file names. Both cause an error dialog to appear when I attempt to mux either directly in mp4box, or by using YAMB.

Sample 2
