after replacing the original Sun JMF by FOBS4JMF, I realized that some Quicktime movies, which I had previously generated from a series of jpg images using a java program similar to http://java.sun.com/products/java-media/jmf/2.1.1/solutions/JpegImagesToMovie.html, were rendered with slightly changed colours. This is quite nasty since I'd like to use these mov files to display some dynamic areas within an otherwise static image.
I suppose the colour change is due to the underlying ffmpeg quicktime decoder/renderer. Does anyone have a clue how to force ffmpeg (or whatever the responsible component may be)
to display the movs using colours as found in the original jpgs?
Thanks four your help --

I don't have a clue why ffmpeg renders colors incorrectly or how to correct this behavior. Anyway, I suggest to try the ffmpeg lists as this is probably a ffmpeg issue.
Good luck!

it took me a while to make clear to the ffmpeg people what the issue was, but when they finally got it they resolved the issue within one night! Cool...
I don't know if you're relying on official ffmpeg milestone builds for FOBS -- if not (and if you want to make me happy ;-), you might want to switch over to the latest CVS snapshot.

The only binary left to build is the Linux version. I'll propably include the latest ffmpeg snapshot to include these changes when I have the time (and resources) to build it. Right now I'm abroad and my only companion is my PowerBook.
Be sure that next Fobs release will include these changes.
Cheers!

Hi,
I'm glad to hear the good news ;)
The only binary left to build is the Linux version. I'll propably include the latest ffmpeg snapshot to include these changes when I have the time (and resources) to build it. Right now I'm abroad and my only companion is my PowerBook.
