Not sure if I can give the code out, I will check. But one of the versions was like what fm does, and the other used the ImageProducer/ImageConsumer api. And I don't remember which was which. I think we went with the consumer api in the end, but not sure. Could hack that in sometime and see if it helps, but don't have so much time atm.

That security exception looks weird. Maybe it's from one of apple's recent updates. They had some security problems. Though it doesn't make much sense when the code is run as an application (i.e. not an applet). I saw some mention that one can disable security checking in java, so maybe google for that will help.

hi,i met the same problem,very the same.

why?maybe some mistakes about the zip of qt for API?i did nothing about it.

I'm having the same problem with Processing 0133 Beta and version 7.4.1 of QuickTime. I've also tried it with Processing 0135.

I've tried loading .avi and .mov files uses the fastermovie examples, but it always crashes. I was poking around with some println statements. Based on these experiments, I've determined that the crash occurs when the FasterMovie constructor makes the call to Movie.prePreroll.

I'm using a PC running Windows XP SP2 tablet edition.

Has anyone seen this work on a PC running Windows XP? Based on the error message that Processing returns, it seems like something needs to be set in the java.policy file. I tried to read up on that at see http://java.sun.com/j2se/1.3/docs/guide/security/PolicyFiles.html

but I don't understand what I need to modify.

Please help!!!!

thanks,

Michael

Hi does anyone have any idea why I'd be getting this error??

Exception in thread "Thread-2" java.lang.OutOfMemoryError: Java heap space.

I'm on pc running xp sp2 with java "jdk1.6.0_05", and "jre1.6.0_05" and processing 135

I was trying to use this new method in hope that it would solve My application export Problem which I'm having. Does anyone know how to get applets working which contain videos?? I've been reading everything I can think of on this forum but seem to be doing loops Sad

You just ran out of heap space. fm might have just aggravated it since it needs a bit. Please consult the java documentation on how to increase your heapspace (I think on the command line it is some -Xm option or such) best daniel

ok,

does the applet actually crash, or does it just print this error and not play the movie? In the latter case I would insert more verbose error printing (to find out where it is from) and if someone runs that we should know more.

edit:

ok, I updated the code, it now prints where an error comes from and also removed a callback that was useless, so maybe that already fixes the problem.

Hi there,
Thanks for the all the work you've thrown into this project!

I've run the updated code and received this error:

Semantic Error: The abstract method "int execute(quicktime.std.movies.Movie $1, int $2, int $3, float $4);", inherited from type "quicktime.std.movies.MovieProgress", is not implemented in the non-abstract class "Temporary_1268_535$FasterMovie"

I'm running Processing 0135 Beta on Win XP and the most recent QT update. The applet does not run, only the console error is displayed.

thanks!
Steve

i still get the error message below. however, the movie does seem to play now(in a loop).

i've got sound but no picture.

I'm seeing the same behaviour. The applet is running, there is sound, but no video. The error message is:

Hmm, what I feared: it doesn't seem to be permitted to install the callback that tells teh app when there is something to draw. This is kinda bad though, as using this callback instead of continuously seeking in the movie as the processing version does is what makes it fast. and it is rally the canonical way to do it: the app should be the slave to the movie, and display the data as it comes. I (or anyone who feels up to it) will have to check on the java-qt mailing list and/or the java docs about the permissions. I think someone here also mentioned you could alter the security policy somehow, though this might make it cease to run in the web. anyhow, its really silly and there should be a cleaner solution. Will report back here if I find any news.
