With the ov511 driver, that would actually eliminate an RGB-to-YUV *and* a YUV-to-RGB conversion. It won't save any USB bandwidth since the native format is already YUV420, but it will save a LOT of CPU cycles. In other words, there really is a strong technical reason why V4L drivers shouldn't convert between standard formats. IMHO, one of the 2.5 goals should be to (at minimum) eliminate the conversion code that does YUV<->RGB from the kernel. I promise to do my part :) -- Mark McClelland [EMAIL PROTECTED] _______________________________________________ Video4linux-list mailing list [EMAIL PROTECTED] https://listman.redhat.com/mailman/listinfo/video4linux-list
