Hello bond,

one question: I want to merge two mp4 files. Is that possible using the bt language in an easy way?
Tried to use quicktime pro but I am not able to passthrough the "new" mp4.

what do you mean with merge?
merging an audio-only mp4 with a video-only one
appending two audio or video streams to to become one?
appending two streams behind each other, without becoming one stream...?

the last one is possible with bt/xmt

use quicktime to append two mp4 stream, if they contain simple profile video
for advanced simple video you will have to demux to avi, merge in virtualdub and remux to mp4

you will have to have a look into mpeg-4 systems to learn how to code this

I tried that but it does not work.
I have two simple profile video streams (both encoded using 3ivX). When I append them I can not passthrough with quicktime.

And when I mux to avi virtual dub is not able to merge neither.

Hello, Bond!
I think something important has changed in GPAC after version 0.1.4. Osmo4 after this version don't play "Star Wars" sample (Decoding Error: Invalid BIFS Node). I exported all video and audio, and then again converted using your script. New versions play it and don't tell about this error. Versions before 0.1.4 don't play new version files.
Also can you look at your script again? I think there is something with moviemenu. "Play", "Pause", "Stop, ">>", "<<" buttons and seek bar don't work anymore. And the error is (ReferenceError: value is not defined: Invalid Script).
And questions:
How to make Russian subtitles display correctly?
Is that any other system players (free or not), except Osmo4 that I can look for?
Thanks in advance.

hm, maybe there is something broken in osmo4 or in my script, which didnt show up till now, dunno

sorry, i dont have much time now to look into it, i am busy for university

hm, i have no clue actually about non-latin characters, the best would be if you ask the gpac guys directly in their forum on sourceforge

there are a whole bunch of systems decoders available (also for free), but most of them are for demonstration purposes and therefore not really powerful and complete enough to handle the full mp4menu (thats actually why i wrote my "profile 2" mp4menu script, which is interoperable with the crappy enviviotv systems decoder)

@pogo stick

I recently used some parts from moviemenu(mp4menu_0.1). I have no problems with it. It works well with Osmo4 (GPAC 0.2.0), didn't test it with EnvivioTV.

If you use the mediacontrol in a different bt script don't forget to adjust the "od" in the javascript. That was my problem after i build it into mp4menu_p2. "^^

(I don't need Chapter. A seek bar,play,pause,stop and the possibility to change the audio track is enough for me.)

So do you mean that moviemenu is working and you are not getting (ReferenceError: value is not defined: Invalid Script)? Or when I move mouse under seek bar it shows (ReferenceError: myval is not defined: Invalid Script) for very short time.
I didn't touch anything in this part of the script yet.

I test it again with Osmo4/MP4Client -> no error. All works fine. But i didn't use the full mp4menu_0.1 bt only the part (mediacontrol) of it.

I would post the bt scribt here so that some body can take a look at it or at gpac.sf.net.

For understanding take a look at:
http://gpac.sourceforge.net/download...ests-0.2.0.zip
(11-mediacontrol-complete.bt)

Your Osmo4 version have javascript support ?

Here is a nice sample too:
http://multimedialab.elis.ugent.be/h2ocean/movie.asp (with isOver)

[Edit] With sw_sample.mp4 i get "Decoding Error Invalid BIFS Node (main service)" too. [/EDIT]

So, that must be the problem. I didn't even think of it.
I can not compile so I just downloaded GPAC from Celtic Druid's site.
There are: 0.2.0 version and 0.2.1 dev from 20/09/04 (with cleaned up multichannel support, fixed faad channel reordering).
Did you compile it yourself?

Some flies from Regression Tests shows me this error also.

I compiled by my self, but at linux.
I tested on my old windows pc (K6-2+ 550MHz)the binray from your link and got the same errors you was talking about. "GPAC Framework 0.2.0 Setup.exe" comes with a js32.dll.

Could be a Problem with my CPU. I don't know for what CPU this binary are intended. Ask the one who build it.

Thanks for the hint, Drachir! I took js32.dll from one of old versions. Now it's working.

Interesting, did you modified moviemenu or just used it? Did you try to add more buttons or change colors?

Thanks for the link. I hope I will be able to download it soon. 95 MB is big.

I almost completed copy of DVD-menu. Only 'Extra' is left. It's not as hard as I thought. Thanks to Bond! Everyone should try it. It's fun!
And I notice something strange with chapter navigation on the moviemenu. For example: When I go directly to chapter3 and click one chapter back I am one chapter2 (that's right), but then when chapter2 is over menu will still 'think' that I am on chapter2 no matter how far movie is going. And if I click back while I'm on chapter5 I will be going on chapter1.
So menu is not counting chapters while passing them. Is there something that can be done about it?

I just used it with mp4menu-p2_0.1.bt.
I didn't changed much it is nice that way it is.
I just placed a black filled rectangle ( transparency 0.7 ) behind the menue. Removed some button i don't need... .

If you want change more, a tool to convert SVG to BIFS would be nice. You cold then draw shapes you need with a program like this: http://www.inkscape.org/ .

MP4 Files would be a good alternative to flash .

basically bifs is very similar to flash

mp4box allows already some .swf to bifs conversion, but its very basic, dunno about svg

but even better would be a tool that could read out dvd menu structures and convert them to a bifs script automatically

By any chance, do you know anyone who is working in this direction?

And what do you think about this:

indeed, thats the way it works atm. the currently played chapter is not detected

this could be surely updated by using the moviesensor to detect what chapter is played atm and update the forward/backward buttons everytime a new chapter is reached
still i never really had the time to implement this maybe someone wants to pick it up?

I tried to play the sample file
http://isabelle.math.ist.utl.pt/~l52768/sw_sample.zip
with the new Osmo 0.2.2 instead of old 0.1.4. It gives ''Decoding Error
(main service)''. Has anyone the same problem? Is possible to fix it?

Thanks.
