Another one I sent last night that didn't get out. Randall -----Forwarded message----- Date: Mon, 6 Oct 1997 21:09:19 -0400 From: Randall Hopper <rhh@ct.picker.com> Subject: Re: [video] frame rate and fxtv Amancio Hasty: |So far I have received the following information from brooktree and I |can't seem to get the set frame rate functionality to work properly |on single frames and with odd/even frames. | |For now, I suggest that fxtv emulates the frame rate functionality by |specifying the full frame rate and skipping frames based upon the |desired frame rate for video capture. Thanks for forwarding the info from Brooktree. I'll take another crack at the driver code with their comments as soon as I get the features I'm currently adding to Fxtv in a good state. If still no luck with decimation, I'll try your suggestion and run some performance tests. The loss of memory- and mem-to-PCI-disk bandwidth due to a full-bandwidth Bt-to-mem stream may not really be significant due to the write latency of disk subsystem with most hard disks. If so, I'll go that route. Thanks for the suggestion. Randall -----End of forwarded message-----
