I posted about a few problems yesterday, I didn't have frame rates handy. I got 320x240x16bpp input and 320x240x16bpp output at 15fps using MIT SHM. I removed the display (XShmPutImage()) and the frame rate didnt change at all. However, removing the Meteor ioctl() to put it into continuous sync mode did pump up the frame rate from 300fps to 500fps, with great delay to the rest of my machine. So, I guess the bottleneck is the Meteor. The specs on the card say it is capable of faster. So am I doing something totally stupid or is there a trick to making it 8 times faster? (640x480x24bpp@30fps) My hiwat is set to my framecount-1 and the lowat is framecount-2. Going from 4 to 8 to 16 frames makes no difference. Also, I'v heard of a program by Amancio Hasty called tv, where would I get this? I tried to look on rah.star-gate.com but I can't reach the machine ever. --------------------------------------------------------------------------- Danny Dulai Feet. Pumice.
