GPAC MP4Box Information, Feature Requests & Discussions [No bug reports]

[bond]

concerning the subtitles conversion issue, defunkt has already reported this bug on SF.great, seems there is a fix already in cvs too:
- misc fixes in tx3g track import, tx3g bt dump and couple of issues introduced in 0.3.0->0.4.0 migration

[defunkt]

Just re-built using current CVS, available here (http://www.ionwerks.net/defunkt/mp4box230705.zip). Hasn't resolved any of my issues with timed text but y'all may fair better. I'm part way through debugging the problem but short on spare time.

what option did you use in YAMB ?

EDIT: I was simply trying to mux, 1No AAC-LC audio stream (in .MP4) and 1No MPEG-4/SP video stream (in .MP4) together....

I've the same problem as SMD...maybe msvcrt.dll fault ? Could you confirm this issue defunkt ?

[defunkt]

Yep. I can confirm that I too am getting regular crashes, in fact the later build seems worse. I doubt it's a compile problem :confused:, rather it's just going to take a while to shake out all the bugs after such a major rewrite. Personally I'm still using an 0.30 release.

[leowai]

Official GPAC v0.4.0 available now.
http://sourceforge.net/projects/gpac

Bad news is I can't get the source compiled without errors. Good news is MP4Box is compiled before the errors.

For who may interested in testing the build, you can download the one I compiled here:
http://rapidshare.de/files/3450273/2005.07.29.MP4Box.v0.4.0.7z.html
And remember, you can report but I am not taking any responsibility for the errors or bugs cause by the program. :sly:
It is compiled from the the source provided. If you use it, use it at your own risk! :thanks:

[neo_anderson]

i'm sorry if this an invalid request, but i just wanted to know if there can be support for ac3 files and vobsub dvd subtitles in future versions?

[bond]

again: there is no point in using ac3 in .mp4
use matroska for that

[Doom9]

and as far as vobsub subs go a few posts up there's this: http://forum.doom9.org/showthread.php?p=689428#post689428. You're seriously stretching my tolerance treshold.
Oh, and AC3 in MP4 is an old story as well.. using the search engine would've yielded that answer.

:confused: ...y'mean ?Sorry... I should have written... "Don't forget to tell your frieinds"

I'm unable to download leowai latest compile, so... what's it like?


Cheers

[yaz]

I'm unable to download leowai latest compile, so... what's it like?haven't tested thoroughly, but the basic functions i use (extract from avi, adding video/audio, ...) worx fine.
it seems as if the syntax were a bit different somehow (or i forgot the exact cli forms). what i've noticed so far is that output is not optional anymore (must always set), and '-out' is not accepted (at least it hasn't worked for me) ... must learn it again ;)

mp4box v0.4.0:
http://mirror05.x264.nl/celtic_druid/force.php?file=./mp4box-0.4.0.7z

[SeeMoreDigital]

I don't know whether it's just me but I've been unable to generate basic muxes with YAMB and mp4box-0.4.0.7z: -

http://img262.imageshack.us/img262/3567/gpac0406ko.gif

I guess it must be down to the "major" rewrite.....


Cheers

[celtic_druid]

Just tested it and it works fine for a simple mux here. I didn't use any GUI though.

[SeeMoreDigital]

Just tested it and it works fine for a simple mux here. I didn't use any GUI though.When I switch to your earlier MP4Box.exe build, YAMB works fine....

....If it is down to code changes I guess Kurtnoise13 is going to be kept busy for a while :eek: I just hope he has the time?


Cheers

[Kurtnoise]

again...same issue just like SMD. Again, it doesn't concern YAMB.

I'm running on WinXP SP2 and you CD ?

[SeeMoreDigital]

Hi Kurt,

Will Jean's comment not have anything to do with YAMB?

http://img276.imageshack.us/img276/7954/gpac0404zg6ek.gif


Cheers

[Kurtnoise]

I don't use GPAC code for YAMB. So, no problem with this...

[celtic_druid]

Win2k SP4. Also tested winxp sp1, no problems there either. mp4box 0.4.0 (from sf.net) and cvs. No problems with either.

Interestingly the sf.net build says 0.4.0DEV whereas the post 0.4.0cvs build says 0.4.0.

Does it happen straight away? Maybe my test clip wasn't long enough?

[Kurtnoise]

mmmh. I just discovered that putting all input files in the same mp4box folder and running by example :

mp4box.exe -add video.avi audio1.aac output.mp4

it works but using the prompt command and putting the path for each input files, just like :

mp4box.exe -add "C:\video.avi" -add "C:\audio.aac" "D:\output.mp4"

it crashes... :confused: There is an issue with the " " ?? :scared:

[neo75903]

wow thx celtic for the build! will test it soon as possible, thx again :)

[Kurtnoise]

Does anybody can confirm my last observation please ? Thanks.

[neo75903]

confirmed!!
it does crashes using paths as arguments.

this didnt crash:

D:\z_DVD>"MP4Box 0.40.exe" -add "audio.mp3" -add "video.avi" "output.mp4"

this did:

D:\z_DVD>"MP4Box 0.40.exe" -add "d:\test\audio.mp3" -add d:\test\video.avi" "d:\test\output.mp4"

but then this didnt:

D:\z_DVD>"MP4Box 0.40.exe" -add "audio.mp3" -add "video.avi" "d:\test\output.mp4"



edit: also discovered that files muxed with this version are not playable int QT7. it returns a "Error: -50: an unknown error occurred".
The file also skips at regular intervals in Nero showtime, only vlc seems to play the file fine.

[bond]

if you find a bug in mp4box, make a bug report on the gpac bugtracker on sourceforge

[Kurtnoise]

This problem seems to be fixed now : http://cvs.sourceforge.net/viewcvs.py/gpac/gpac/applications/mp4box/

a new fresh cvs build please... :D

[neo75903]

idd filling a bug report does help :)

[celtic_druid]

Done.
http://mirror05.x264.nl/celtic_druid/force.php?file=./mp4box.7z

[SeeMoreDigital]

Thanks CD... I've just tried it with some basic muxes and it appears to work fine :)

I was hoping the new build would be able to accommodate Nero's VobSubs during the muxing of additional audio streams or chapters... but it can't :(

[neo75903]

thx dude, thats what i call service :)

[bond]

http://img282.imageshack.us/img282/9913/vobsubs5ge.gifwith that path you need a " " around the path, cause otherwise mp4box might think that the path ends after c:\documents

[SeeMoreDigital]

Hi Bond,

Here's the fuller picture ;)

because it's not finalized in the code...just wait & see. :)

I noticed this while investigating another problem (http://forum.doom9.org/showthread.php?t=97536), but got no response.

Basically, mp4box produces different mp4 files given the same input. Specifically, if I do the following:

mp4box -add input.264 output1.mp4
mp4box -add input.264 output2.mp4When I compare output1.mp4 & output2.mp4, they are not bit-identical! While both mp4 files playback correctly AFAIK, the fact that they differ is perplexing.

EDIT: fc shows that the differences are always in the beginning (in the one track case), so somehow the track header is different? A timestamp, perhaps?

srt -> ttxt tool
I have created my own tool for (maybe ;) ) correct srt->ttxt conversion until GPAC developers fix this bug.

You need Microsoft .NET Framework 1.1 to run this tool!

Note! Your subtitles must be in UTF8 encoding!

Seems like mp4box don't convert Underline style at all :(

[Isochroma]

Still getting 16x16 pixel output from .264 to .mp4 conversions, using the latest mp4box 0.4.0

[adaml]

anyone know if mp4box has the ability to author a streaming mpeg4 video input.....I was hoping I would be able to mux subtitle information with the live video.


If this isn't possible...it would be a cool feature in the future

[leowai]

Just noticed the gpac updated yesterday.

@dimzon, did the following CVS update solved your problem?
Latest CVS Changes 31/08/05
- fixed UTF8 vs Win-CP text handling (BT and XMT parsers, subs->bifs and subs->ttxt converters)
- improved SRT -> 3GPP convertion - now accepts any number of <b>, <i>, <u> tags at random places. Also cleaned up TTXT->SRT conversion.
- fixed bug in unknown stsd boxes handling
- attempt to fixe gpac compilation on 64 bits platforms


- Edit -
MP4Box v0.4.1 Dev cvs binary build 2005.08.31
