Hope that get's your attention
I came a cross a open source app (PC & Mac) that Capture the video stream thought the USB 2.0 cable to your computer .
Here the
link to the software called "EOS Camera Movie Record 0.3.3 beta" , did some testing with ML installed on my 5D2.
There's some limitations of course , you don't get the full HD and it's more then SD (720x480) it's some where in between 1024x680 as a AVI .

In Crop mode you get a bigger frame size 1120x752 and for some reason the encode rate is very high almost 85 Mbp/s where as in 1:1 it's around 50 Mbp/s

Configuration window , I had it up to 10MB buffer but didn't see any real difference in performance or compression .

Here are some sample in my dropbox that can be downloaded

I Know way back a few years ago A1ex had this working but not sure if it was internal recording or not , I guess I should mention it's YUV @ 4:2:2 MJPG compression same as the 1DC .
The big drawback is the lack of resolution , I was looking at the
code but really could not see where this limitation is . Or could this be a Jpeg chip hardware limitation ? If ML could implement MJPG compression over h264 that would great or for proxy record it limited to 1024x680 & 1120x752 resolutions , mind you I did not try to record raw video at the same time as USB capture , I was being cautious not to brick my 5D2 .
One thing I did notice thou if you change the Picture profile from Landscape to Neutral and customize the setting , as this effect the live view the capture rate in 1:1 mode drop down in fps from 24+ to around at the lowest I saw 22 fps but this dose not effect 3X Crop it still captures at 24p . So this leads me to believe that the native Color/Picture Profile is Landscape mode for liveview
where the camera resources are taxed that much more to dropdown performance .
Will I hope this is helpful to anyone if you need to capture a live event for hours , just not at full HD that all , unless some dev. knows how to change the resolution or if we could record internally with raw that would be better
.
Thanks for reading , have a great day !
