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? :)
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 :).

[Kurtnoise]

Waiting for a new MP4Box compile.
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 :
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...
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.

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=571738&group_id=84101&func=browse

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

[Kurtnoise]

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]

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]

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]

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

[Kurtnoise]

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]

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]

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 (http://s55.yousendit.com/d.aspx?id=2VJX5GNUIWDKE1FZSTC1NBI434)

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 (http://s55.yousendit.com/d.aspx?id=34GRAMO00B9F230W3ES8GWS9LG)

[Kurtnoise]

Replace # by _ . Such as Beet The Vandel Buster_45.264

mp4box associates some extra characters with #...

[Varium]

Oh ok. Yeah, thats fixed it for me. Thanks a lot Kurtnoise, I didn't think it was caused by something so simple. I'm glad everythings working now. YAMB is a really useful tool btw, so I'll give my thanks.

[Kurtnoise]

Hi,

Does anyone have some troubles with my own MP4Box compiles coz some people send to me some crashes during processes ? If yes, please give me some details...

I can't reproduce these crashes myself so I ask...

[SeeMoreDigital]

Funny you should mention this....

A couple of days ago I used the latest YAMB 1.5 build to de-mux an 800MB (1CD back-up) MPEG-4 AVC back-up of Terminator 3, I generated using Recode2.

The de-muxing of the MPEG-4 AVC video and 6Ch AAC-HE audio streams went okay but when I attempted to re-mux the streams (along with my newly "named" chapters), YAMB completely stalled at the video stream importing stage!

Everything went fine with the last build of YAMB 1.4


Cheers

[Kurtnoise]

I asked for MP4Box crashes not YAMB...:o

[SeeMoreDigital]

I asked for MP4Box crashes not YAMB...:oIndeed.... I don't think it's YAMB that's crashing!

Tell you what.... I'll perform the same re-muxing task again with the latest YAMB 1.5 build but with different versions of MP4box.... and get back to you!


Cheers

[Kurtnoise]

Heya,

Some infos concerning MP4Box and gpac stuff : vobsub support has been officially integrated into the cvs today. So, great work Falco. ;) Now, a MPEG TS demuxer is on the way. Feel free to test it.


As usual, my MP4Box compiles for win32 are available here (http://kurtnoise.free.fr/mp4tools/).

As usual, my MP4Box compiles for win32 are available here (http://kurtnoise.free.fr/mp4tools/).Given the "extreme" importance of the proposed .TS de-muxing implementation.... I've taken the liberty of starting a new thread about it here (http://forum.doom9.org/showthread.php?t=111470).

Hope that's okay ;)

[chipzoller]

Since this has to do with mp4box crashing, I'll post mine here:

Using 0.4.1-DEV (size 1,736,704 bytes) of MP4box and the crash happens with this via cli or via YAMB 1.6.0

Encoded Legend of Zorro in x264 MP4 with megui, and audio aac q=0.34 with the new nero aac encoder. MP4box crashes when importing the video (it looks like) track. I'm not sure what other info. you may need, so let me know what else I can provide.

[Kurtnoise]

With the last daily build ? with the 20060522 version, MP4Box crashes for me too with ND aac stream.

Use the 20060515 or 20060505 builds instead.

[JoeBG]

@ Kurtnoise
mp4 box crashes with the versions 22.05 and 21.05 when I mux m4v streams. Down from version 19.05 no problems.

[Kurtnoise]

If you found a bug, report bugs directly on SourceForge...

[JoeBG]

You´re right!

[Kurtnoise]

with the 20060522 version, MP4Box crashes for me too with ND aac stream.
bug with mp4 audio streams has been fixed in the CVS now but MP4Box still crashes with raw mpeg4.

:: http://kurtnoise.free.fr/mp4tools/MP4Box_20060602.zip

@JoeB : if you use xvid encraw, choose avi as output. This should be ok temporarily.

[SeeMoreDigital]

Just tried the new compile with a Recode2 encoded test sample (with 2No AAC audio tracks and 2No VOBsub subtitle tracks) and it muxes very quickly indeed :D

The re-muxed VOBsubs, still appear to be longer than the sources VOBsubs though... :(


Cheers

AFAIK, Falco hasn't fixed yet this issue...

[Kurtnoise]

mp4 box crashes with the versions 22.05 and 21.05 when I mux m4v streams.
Fixed now...A win32 build is available here (http://kurtnoise.free.fr/mp4tools/). :cool:

[Hyper Shinchan]

Hi guys! Can you try to import a subtitle that show in a lines the character '?
In all the builds that come after the first part of March it dosn't work, the player (QuickTime, Osmo4, Halii+vsfilter) doesn't show the characters after that character, but the mp4s muxed with a build that was made before the second half of march 2006 (both Kurtnoise and Celtic Druid's ones) work perfectly.
I think that there is a bug in MP4Box, but I'm not so smart to find it, sorry.
Can anyone help me? Would I report it directly to gpac?
P.S.: Why the link for the celtic druid's build doesn't work anymore? It's onlly me?

C'ya!

[Kurtnoise]

No problem here...with what kind of subtitles format did you have this issue ?

[bond]

' ' is used for linebreaks i think

[Hyper Shinchan]

My subtitles are srt converted to gpac timed text.
please try line like:
"Cantami o diva l'ira del pelide Achille"
All the character after the ' disappear.
As you know I can't connect to internet unfortunately, but I'll make a pair of sample this afternoon and I'll post them as soon as I can.

[Kurtnoise]

As I said previously, this works fine for me. Tested with your sentence and several french sentences which have also the same syntax. Maybe, this is a problem from your player/splitter ?


btw, it seems that the last MP4Box build doesn't delete the tmp file when we try to import & mux different streams. Does anyone have noticed that ?

[nurbs]

I can remember having problems with that too.
On one movie I accidently OCRed " as 2 times ' and then sentences would disappear. I can't remember if it also happend when there was only one ' but I think so. Maybe it had something to do with an italic '.
Anyway I somehow got it working and it was probably just a small problem.

[Edit] Maybe there has to be a space between the 's as Bond said in post #280

[Hyper Shinchan]

Maybe, this is a problem from your player/splitter ?
As I said I've tried different players, the only problem with the players that I've noticed is that italic fonts are displayed in a wrong way, bigger than normal with Halii+VSfilter, but the file made with the old builds play well, the new ones no.
I've attached a file that include an srt subtitle, the ttxt's one and the resultant mp4s made with the old and new build, please mod validate it.
[Edit] Maybe there has to be a space between the 's as Bond said in post #280
It could be... do you use space Kurt?

[Kurtnoise]

No...I didn't use space. Basically, there is no space between l and ' (at least for french language...same thing for Italian I guess.)

[IMOON]

Hello Kurtnoise13,

I can confirm this bug. I use your last build of mp4Box and Yamb.
I have tried to mux this ttxt to mp4

<TextSample sampleTime="00:07:16.007" text="'Sieh mal, Teal&apos;c, wir leben schon lange''alleine in unserer Ecke der Galaxie.'">
</TextSample>

All the character after the &apos; disappear.
If I export the subtitle to ttxt it locks like this.
<TextSample sampleTime="00:07:16.007" text="'Sieh mal, Teal'''''">
</TextSample>

also if I try to convert the ttxt directly to srt something goes wrong.

90
00:07:16,007 --> 00:07:21,286
Sieh mal, Teal





P.S.: Version 20060303 of MP4Box is OK.

[Kurtnoise]

mmh...how did you create this ttxt ? With SubRip ? Directly from MP4Box ?

[chipzoller]

Kurt,

Used Yamb 20060512 and mp4box 20060610 to extract vobsubs from an MP4 file I encoded into a separate MP4 file (RAW format failed) so I can import the whole file into MKV container (3 streams in this MP4 file...only audio and video were picked up by mkvmerge 1.7.0). When adding the resulting mp4 file created from vobsub stream and importing via mkvmerge, it tells me "the input file contains no tracks." I remember you mentioning a while back about your builds of mp4box now supporting demux of vobsub stream, but aren't you still working on being able to demux to the .idx/.sub files? In any case, this this an mp4box problem or mkvmerge?

[Kurtnoise]

mmh, not me...;) but Falco and for the moment we can't extract directly idx/sub from mp4. So, if you have a mp4 containing vobsub file, you can't use it for mkv/divx. In this case, use directly idx/sub files from vob or (re)create them with a srt file.

This is not a MP4Box or MKVMerge problem.

[chipzoller]

Kurt...sorry :)

I understand it is not yet possible to extract .idx/.sub from a MP4 file with vobsubs, but is it possible to extract this track to an MP4 file itself, nevermind the correct formatting exported along in the .idx file. I thought for sure it would at least do this.

[Kurtnoise]

is it possible to extract this track to an MP4 file itself
Yes it's possible but only MP4Box will be able to use this kind of file...for the moment.

[IMOON]

mmh...how did you create this ttxt ? With SubRip ? Directly from MP4Box ?

I used Subrip 1.50 beta 3a to extract the ttxt from the vob file.

[chipzoller]

Yes it's possible but only MP4Box will be able to use this kind of file...for the moment.

Kurt...thanks for the info.

[Kurtnoise]

I used Subrip 1.50 beta 3a to extract the ttxt from the vob file.
Save your file in Unicode...

Same thing for you Hyper Shinchan : reopen your srt through SubRip and save it as Unicode form.

This should fix your problem.

[Kurtnoise]

From the last cvs :

Latest CVS Changes 12/06/06
- added MPEG-1/2 raw importing (extensions: .m1v and .m2v).
- cleanup of gpac/src/Makefile: no more recursive makes for libgpac

http://kurtnoise.free.fr/mp4tools/MP4Box_20060612.zip

[SeeMoreDigital]

Oh cool.... Great stuff ;)

[Kostarum Rex Persia]

Cool, man. Great news.

[Hyper Shinchan]

Save your file in Unicode...

Same thing for you Hyper Shinchan : reopen your srt through SubRip and save it as Unicode form.

This should fix your problem.
Tnx for the hint. I'll try it and I'll let you know if it works for me.
Anyway what does it mean? Maybe the older builds were able to perform an UTF-8 conversion before to encode the srt to ttxt???

[Sharktooth]

Did anyone test this latest gpac revision? Is it safe to add it to MeGUI auto-update repository?

[Hyper Shinchan]

About subtitles:
Arghhhh!!! It doesn't work! i've tried to save my srt in utf-8, I've tried to reconvert the ttxt in utf-8 and I've also tried to make a ttx directly with subrip 1.5b3, but it doesn't work with the new builds, but it works with the old ones...
Unrelated: why the newer MP4Box build doesn't show the progress bar while they are importing a file? They show it only while they are writing the file....
