HDMI experiment

[Alex]

Quick and dirty HDMI experiment (550D/1.0.9):
ChangeHDMIOutputSizeToVGA. Does it work?

Usage: Debug->Don't click me, at your own risk.

If it works, it will become an option in main builds.

Did you do a new release with that or it is only for developers?

It is just a test, and right now I have the confirmation that it works, yay!

Just as a "gossip", if nobody knows:

the Canon Firmware (even without ML) doesn't change the output
resolution hitting "REC", having the same behaviour of 7D, when the
input signal option (on the LCD!) is set to DVI instead of HDMI (of
course the ratio is stretched..).

I have a lilliput 7'. Weird. Is it related to your new findings?

Second experiment (only 550D/109):

1) Review the code from
https://bitbucket.org/hudson/magic-lantern/changeset/e6ae1485c3d9 (as
I didn't try it on my camera)

2) Enable the relevant setting from menu

3) Tell me if it works and how it works, as detailed as possible.

Now for the adventurous (this may be risky):

4) Hit record and then Don't click me.

[Alex]

Sorry, wrong autoexec.bin. This is the right one.

[D.K. McPherson]

Unfortunately For me it still does not work with my (Buy cheap get cheap) Leadstar monitor. The most it records is a 2 second clip then stops and reverts back to the live view.

[Alex]

You have missed Step 1 ;)

More feedback about these tests here (scroll down to last comments):

[Alex]

Got positive feedback from Marvin on Vimeo, so here's the third test.
It does the same thing, but without delays and debug messages.

The "don't click me" button still attempts to do this http://vimeo.com/6618825
But I doubt it will work (maybe with low bitrate or 24p only?)

[Simon Larcher]

I have read both the code and the comments on Vimeo. I don't have a HDMI monitor but I am still curious since I plan to buy one.

I am not sure I understand correctly, though.
Do you try to simulate the aspect and resolution of a HDMI screen on the liveview so that there is no gap when record starts ?

And also be able to simulate a HDMI screen on the integrated display to test elements like magic zoom etc... ?

Thank you for your work

This code reduces the resolution to SD, so there will be no black
screen when you start recording.

False color works with this trick, and probably everything else except
magic zoom and focus peaking.

My experience with smallhd dp6. I turn on the camera and the monitor shows me everything properly for 5 sec the everything freeze video included and camera turn off itself. Need to take off battery to bring it back. Tried 3/4 times same result. Any lucky one who got it work? Thanks

[Alex]

Try this one.

[Cri]

Sorry, Alex
Try this one what?is it the autoexec fileishould try? How will i do it? Never put my hands on that file. If u explain to me i might give it a try. Thanks

> <autoexec.bin>

[Cri]

I replaced the autoexec bin file. But this time does not stop but i only see half the audio meter bars and the menu it's shifted to the left. So i cant read the audio menu option.

You have missed Step 2 ;)

[Shawn Wytch]

hey i have a question is there a way to use the hdmi to hook up to your laptop and take over the laptop screen is this possible?

Email me at too...@gmail.com 
Or call me at 316.312.5584 ask for Shawn

[Cri]

Come on Alex don't be mysterious, what's now this step 2? :D

[Shawn Wytch]

i hope this works?

[Greg Fiske]

Alex, same thing with the new autexec. Force vga should be off
correct? Could you clarify "Enable the relevant setting from menu ",
I don't know if I'm missing anything.

[Cri]

I dont see any force VGA, where is it in the me u?
