Media controller controling shapes and video in mp4 - possible?

[EmJayEm]

Hi,

I want to make a circle, appear at time=5 seconds with a duration of 2 seconds in a scene which lasts 10 seconds. I want the entire scene to be controlled by a media controller (pause, stop, play, rewind, fast forward).
e.g. Rewinding to time=5 seconds makes circle appear.

I would like the media controller to control a video aswell.

Is this possible to author in VRML .bt format and then convert it to an mp4 file using mp4box?

Thanks,

EmJ.

Should be possible. Take a look @ GPAC Regression Test Suite (http://gpac.sourceforge.net/downloads/gpac_regression_tests-0.2.1.zip)
Questions about authoring can be asked here: MPEG4 Authoring (http://sourceforge.net/forum/forum.php?forum_id=327349)

Yes it is possible to author this in BIFS text (*.bt) and convert it to mp4 with MP4Box.
