Could the upper limit of hugetlb be increased, or is it a function of page size? Also, I found that the size given to bigphysarea is in pages, not in KB. So what is being asked for is actually an 8MB buffer (I guess it is a double buffered operation). 2MB is close but not quite enough, it appears. I did Cc: the mjpegtools developer so maybe he can elaborate. -- Ryan Underwood, <[EMAIL PROTECTED]> -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble?
