Oooh, I see the problem. I didn't know that was the case with exporter, though I can't say I'm surprised. The JNI portion of it has never seemed to me to be too robust. Probably worth flagging this as a bug for Apple.
Perhaps you can try a hack on it, by saving only the resource file for the movie, then spawning a separate JVM process(via exec()) to do the final export. I'm not sure, but I think I remember reading that the ffmpeg folks were working on QT resource file support, but maybe it's just wishful thinking on my part.
Sorry I can't be of actual help.
Good luck.

Thanks for the tip Alex. I've already tried this and it
does create a single video track but the problem is that the exporter does not play nice in a multithreaded scenario. If i start 2 exporters at the same time, each in it's own thread, the first exporter will block the second one until it's done. Any thoughts on why this happens and how to do exports in parallel would be greatly appreciated.
Thank, Erik

What you want is to export the movie rather than flatten. There's code in Chris' book and code on this list on how to save and use export settings programmatically. Do a search on 'atom container' and 'movie exporter settings'.
I have a problem flattening a movie. My goal is to flatten a series of merged movies into a movie that contains a single mjpeg track and a single audio track. The flattened movie will then be passed to ffmpeg that creates a flash video.
My problem is that the flattening of the merged movie creates a new movie that contains 2 mjpeg tracks and a single audio track.
All the movies that are merged contain a single mjpeg (dimension 320x240) and audio track. The movies are merged using the following method...
public static Movie merge(Movie[] movies) throws QTException {
QTSessionCheck.check();
Movie mergedMovie = new Movie(); for (Movie movie : movies) { fitInto(movie, maxWidth, maxHeight); movie.insertSegment(mergedMovie, 0, movie.getDuration(), mergedMovie.getDuration()); }
return
mergedMovie;
}
...and then the merged movie is flattened using the following method....
Movie merged = QTMovieMerger.merge(movies);
QTFile flatFile = new QTFile(new File(outputPath, ticket + ".mov"));
Anyone have any idea why this produces two mjpeg tracks in the flattened movie? The first and last movies in the movie array become one track,
Thanks in advance, Erik Hedenström
P.S. I agree with Shay Telfer, if you haven't bought Chris Adamson's "QuickTime for Java: A Developer's Notebook" go get it
immediately. It saved me a ton of time, and kept me from posting silly questions (hopefully the one above isn't) to this forum. _______________________________________________ Do not post admin requests to the list.
