Hi,
  Is it possible to reach a frame rate of 30fps on Ekiga 3.0.2 with H264 enabled on Ubuntu 8.04 ( kernel 2.6.24-23 )...?
I am using the Logitech QuickCam for Notebooks Pro 2Mpixel camera. I have observed a  range of  transmistted / received frame from 21/9 to 26/46 with and average of 24/12 most of the time. If there is some way of achieving a ratio of 30/30, please let me know.

On wiki.ekiga.org <http://wiki.ekiga.org>, it is mentioned that using setpwc tool, we can set the philips webcams to support 30fps. But this is limited to philips webcam only..!!
Please suggest a solution for logitech camera.

First things first. The numbers you see are for TX and RX (transmitting and receiving). The first set of numbers are the TX values. This is the frame rate that you are sending. The second set are the RX values. You can only control the TX values. The RX values are dependent on the person you are calling.

Secondly, webcams require *LOTS* of light to have high frame rates on their automatic settings. We're talking sun light's worth of light. However, you can adjust your webcam manually. Modern Logitech webcams use the uvcvideo kernel driver and therefore can use the libwebcam library for access to your webcam settings.

I have created a GTK+ 2.x interface[1] to the libwebcam library. This will allow you to manually configure your webcam even in real-time during a call. You may also wish to visit the official Logitech website[2] for the library.
