Re: F11 on XO-1: keyboard + mouse not responding.
These are actually relatively old.

Re: #10045 HIGH 1.5-sof: XO-1.5 Record audio/video are out of sync with each other
Given that the main memory is one eight to one quarter the size of the storage medium, I'm surprised at the effort being invested in recording straight to the storage medium. Especially if that storage medium is arbitrarily slow! Cheers, wad On May 15, 2010, at 7:02 AM, Richard A. Smith wrote: > On 05/13/2010 08:07 AM, Benjamin M.

If it is then its broken and no wonder its skipping. Raw 640x480 RGB at 30 frames a second is 27MiB/s. Even if you use a YUV format with 16bits/pixel and 15 frames a second its still 9MiB/s which exceeds the sustained write rate of a class 6 card. We ship class 2 (2MiB/s). If we can't do theora on the fly then we should be doing MJPEG or HuffYUV (if you wanted a lossless format). Although HuffYUV is still going to be much faster than a Class 2 card.
