YUV and RGB Formats

Question

Hi,
I bought a webcam recently to use with JMF. The camera can be identified by JMF Registry and shows that it supports YUV and RGB formats. However, in my code, it says that it only supports YUV. Here is the code:
FormatControl y = (FormatControl)player.getControl("javax.media.control.FormatControl");
Format [] x = videoDevice.getFormats();So I ignored this and selected the format I was looking for anyway using the setFormat method. It compiled and ran but when i checked it, it did not accept the YUV format I chose from the list. Instead it used an RGB format. Im not sure how this can happen as the list of supported formats did not contain any RGB formats. Any help would be greatly appreciated. Thanks

ThanksSo, you're setting the format of the player that you're using to watch the video from your camera? If you expect that to set the format that the web cam is giving the camera, you're expecting that setFormat command to back-track to the DataSource that's going into the player, and if you just think about that for a second...yeah, not going to work.

That code will correctly set the format on a web cam.
