Ok, Ive checked. The weird effects happen in live view, not recording, without fps override enabled (OFF), turning  live view on and off seems to fix it momentarily.
If Im not mistaken it only happens in fps above 24, 29.9 for instance, setting fps override (ON) at 24 fps seems to fix it.

I will do further testing when I can, the blueish/snow/half mirror was happening in high resolutions and aspect ratios in liveview but not even recording yet if I recall right, in fact those might had not even been set yet.. Just liveview no recording, quiet sure..
Once more, thanks a lot heder!

The closest I get to 924x388 is 928x388 at 2.39:1 .. What aspect ratio are you using? Or it might have been a typo..

The Blueish cold temperature screen, snow, or half-half screen effect shows on liveview, it does disappear if you turn it off and on again, at least temporarily.

Haven't tried the x5, x10 zoom yet.. Should I be recording with zoom on?

I am using an old 2Gb CF card for testint Magic Lantern, from the year 2008 or so..

Btw, what is binning? What does the SRM acronym stand for?

If I go as low as 640x160 and 5:1 or 4:1 aspect ratio i get continous mode in green letters, that seems good..
Under heavier loads i get blueish cold temperature screen, or snow, or splat screen half-half mirror effect..
How do you get those non standard resolutions of 924x388?
Do you use fps overrride to set the 24 fps?
What do "Use SRM job memory" and "Small hacks" do? How can I load the mlv_play module for playback?
I am enjoying very much testing the video on the 40d.

Ok, MLV app is working like a charm, thanks!
My vids are quiet buggy though, in the other hand they were my first try with raw video..
Contrast seems really hight, sometimes the screen just fades to black..
Still amazing to have been able to record some vid with the 40D!
Looking forward to mjpeg.

Why does my image fade to black when recording raw video? Could that be bad for my CMOS sensor or something? Should I stop the vid when that happens?

Hi heder!

I finally got ballsy and went beyond qemu to test your 40d port in my camera, it works and I am able to play Arkanoid and mess a bit with the intervalometer.

Been trying the raw video but don't understand very well how it works, it seems to stop automatically after short periods, and also then after I don't know what to do with those files, how to play those raw vid files, looking at my CF card I think the are the ones with .mlv extension..
If someone knows how to play them that be great.

Those mjpeg new features are looking great, wish I could help somehow.

Is great to see that finally unfold as we knew the 40d might be able to record video since 2008!

Thanks a lot and a big hooray to heder!!!

Managed to boot your build in qemu, now i can boot both canon firmware and your ML build.



Next I'll try to run it in the camera and dump the RAM.. Also.. How would one go about finding the half shutter button? Id like to try that.
Thanks for your work heder!

Ok. I finally got to emulate Magiclantern 40d on qemu-eos. If anyone is following that process you need to use mount.sh script within qemu-eos to mount cf.img (It's the virtual compact flash), so you can copy the ML files in it, otherwise you get permission issues, also but not least the key to launch ML menu in some computers is Supr instead of Del, just saying cause that bit got me stuck for a while.
When i have time i'll play a bit with the ML menu and see where to go from there, once more thanks to everyone that made it posible.

As it turns out the canon dump was working on qemu, my terminal screen was printing what you posted, I was just not pushing the right buttons, when i pushed menu (M key) and I saw the canon interface couldn't believe it.
Now I got to play a bit more with it and run/load the 40d magic.
When I press backspace key (delete button?)  nothing seems to happen, I've tried also D key for direct printing, how do I load the magic lantern?
Hopefully at some point I might be able to do some debugging and/or find some calls and stubs to help your effort.

Im trying to run the 40d dump from my camera in qemu-eos but is not working, it goes in a loop, does it work for you guys? It seems to boot though..
Also manage to get the Magic Lantern boot screen with boot=1 option.
Is it maybe the wrong approach and is the heder magic lantern that I should try and run in qemu?
Do I need to compile magic lantern 40d in some special way for qemu? Or will the last heder build run in it and no need to compile myself?
How do I run the build?
I'm stuck at this point, I want to try and help, but i'd like to load the software in qemu before trying it on my camera.
Any help appreciated, thanks.
Also would like to say thanks and hurray to heder for pushing forward the 40d, been following this thread 10 years and tried to do it myself lol, just not skilled enough. Following your footsteps and learning along the way.

Is it working? Did you manage to enable video? Will you share?
