Hi,

Okay, here's the deal. I have JMF 2_1_1e installed on two boxes -
Windows performance pack on a Windows XP box, and Linux Performance
Pack on a linux redhat fedora core 1 box. I am using Java2 SDK 1.4.2
on both boxes. I have a Logitech QuickCam 3000 Pro (USB)which has a
builtin microphone. I plug the quickcam into the Windows box, fire up
jmstudio and viola, I get video and audio. Wonderful. I plug the
quickcam into the Linux box, fire up jmstudio and viola, I get video.
Under "File->Preferences-Capture Devices" I ask it to detect the
capture devices and it gives me "v4l:Logitech QuickCam Pro 3000:0" for
the video capture device and "JavaSound audio capture" for the audio
capture device. When I try to use tha audio capture device, jmstudio
gives me an error message, e.g.: "Unable to handle format: LINEAR,
22050.0 Hz, 16-bit, Stereo, LittleEndian, Signed". It will give me the
same "Unable to handle format: <fill in format here>" error regardless
of what format I choose. The microphone is detected by the O/S
properly (no errors) and all the proper modules load automatically,
but JMF just can't seem to find it.

Thoughts? suggestions?

John
