I know this is a Gnome upstream wish.. but also that this is a good place to spread an idea.
Is there a huge difference in using Screenshot instead of recording your desktop with "Istanbul"?
And between recording a video with your webcam with "Cheese" and grabbing audio from your mic with "Sound recorder"?
Can you now manage the output files in all those gnome programs as you wish?
NO.

So, let's build a software using the existing code that fill full the requests of today's users..
I image a place where i can
- take pictures, record audio and/or video of my desktop
- take pictures, record audio and/or video from my webcam and/or my mic
- configure output file proprieties (.avi/.ogg, bitrate, resolution..)
- easily

Do you think my idea of a "Recording center" is not meaningful? That now those gnome programs are serving us well? Well, I don't think so.

Best regards
Alex
