3rd party flashes in LiveView

[Alex]

Here's a trick which should enable third party flashes in LiveView in Rebel cameras.

How to use this:
- Enable it from Shoot menu (advanced mode)
- Go to LiveView
- Press the shutter button **gently** to take a picture. If you are nervous, it won't work :)

How it should work:
- When you press the shutter halfway, it will exit LiveView temporarily
- When you fully press the shutter, it will take the picture
- When you release the shutter, it will go back to LiveView.

This is not really friendly with the shutter count, but it should work.

As far as I know, this problem affects the 550D, 600D and maybe 500D. So this function is only enabled on these 3 cameras. I've only tried it on 550D, without any flash.

More info here (actually it was requested many times): http://vimeo.com/groups/magiclantern/forumthread:244149

Did you get the test you requested on Vimeo 4 months ago? If not, I
have a 550 and the "bulky, overpriced top-of-the line Canon flash", so
I can run the test for you.

Good hint. I've tried changing the silent mode setting ("stolen" from
60D) but it has no effect.

Can you run property spy while attaching an E-TTL II flash to the hot
shoe?

Use this autoexec (compiled in debug mode): dl.dropbox.com/u/4124919/
debug/autoexec.bin

You should get a screen which looks like this: youtube.com/watch?

Record the screen with a second camera, both in LiveView and outside
LiveView, and insert/remove the flash a few times.

Those numbers will tell me which settings are being changed in the
camera."
