If you are using O_DIRECT raw I/O its in multiples of 512 as you write it and DMA directly from user space. For non O_DIRECT its buffered up sanely In actual fact I suspect you are not going to be able to do it without a lot of RAM and pretty high end disk subsystems. _______________________________________________ Video4linux-list mailing list [EMAIL PROTECTED] https://listman.redhat.com/mailman/listinfo/video4linux-list
