I'm trying to figure out how/what package would allow overlay of text, like a timestamp, onto a videostream. Must one have specialized hardware to take composite video-in (from a CCD camera) and insert a timestamp and possibly other user data into a portion of the image before capture to memory or displaying into the framebuffer? I'm using the 2.4.21-rc1-ac4 with the stock bttv (878) driver with ATI TV-Wonder and soon the Hauppauge ImpactVCB. Could one capture to RAM, scribble the text on top of the image, then encode/compress into an avi file? I don't need to display the image in real-time. Would the video loopback device come in handy? Using MJPEG capture then post processing the frames to insert text then thru ffmpeg might be simplest, especially if the was a hack to ffmpeg to mask/overlay another image. I'm also puzzled about the status of v4l2 and bttv-0.9 in 2.4.2x kernel, is it supposed to happen anytime soon? Geoff -- Geoffrey Espin espin@xxxxxxxxx
