[sip-comm-dev] Webcams on Linux ?


#1

Hello Emil,

I have the webcam Philips ToUCam Pro which is working fine. I tested
with the tool jmstudio of JMF Linux Performance Pack.

However, I cannot capture audio only and audio + video.

I know that it's more a JMF problem and a problem in the configuration
of the system but maybe, you can help me because plenty of JMF users had
this problem and may be you solved it to make SIP Communicator working.

Thank-you very much in advance,
Laurent

Note :

Here is the error that I have when I try to capture Audio + Video :

Audio not supported: interface TargetDataLine supporting format
PCM_SIGNED, 44100.0 Hz, 16 bit, stereo, little-endian, audio data, and
buffers of 22050 to 22050 bytes

Hello Laurent,

Personally I've tried with Logitech QuickCam Pro (uses phillips' pwc and

pwcx) and TerraCam USB

Anyone else had any other experience?

I think you'd get more substantial input on the JMF-INTEREST list

Cheers
Emil

Hello,

I would like to know which webcams are working on Linux with SIP
Communicator (JMF in fact).

Or, which model of webcam is used to test SIP Communicator on Linux ?

Thank-you.

Hello Laurent

I don't see what might be causing ur problem. If u don't need the camera - try removing it from the JMFRegistry using the Settings menu. Other than that I don't think I'll be able to look into the matter very soon cause I've other priorities right at the moment.

In case u figure it out. It'd be very kind of you to contribute the solution.

Cheers
Emil
