If you're interested in a somewhat faster motion detection, and willing to test, let me know.
@srsa_4c :  having played with MD a bit,  I'm curious.  What have you got?

The attached build should take care of this issue. Please report if you find a problem with it.
It seems like the overrides still do not work on quick shutter release.
That means the "magic potion" (a piece of code that is supposed to help with this issue) doesn't work. I'll leave it like it is then.

I would try it, but outside of testing your build I have never used it.
You can test this by simply watching the live histogram or zebra, no need for a motion detection script.

... I should have said "Would you like to test a vid_get_viewport_live_fb() implementation based on values found by the sigfinder?"   :-[
Seriously, I don't want to blindly implement it, because I may get the number of buffers wrong (this camera seems to have 3, not 4).

Sure, I'll test it.

@cheddar66

Attached is a build with that motion detection related change. Unfortunately proper testing would be a bit tedious (unlike I said earlier), so I'm only asking you to enable zebra and report whether the zebra display is working correctly. Since zebra is slow, you probably won't find a difference compared to the previous builds.

Also, I have disabled that fast shutter press related hack, since you have reported it to be ineffective.

Yes it works correctly.  Like you said, I can't see a difference.

Does the 'Dark Frame subtraction' control (RAW Settings) work at the moment?

There are some problems with other cameras with the 'nrflag' values found by finsig_dryos.

I've updated the code and the new value found for the A3100 is:
Code: [Select]
static long *nrflag = (long*)(0x5cd8+0x08);

I would appreciate if someone can test this and let me know which value works (if any).

Phil.

Do you see the red CHDK logo when your camera starts?



Have you tried quicky pressing the CHDK <ALT> key?  For he A3100,  the key to press is  labelled "Review Photos" in this picture :

Hello! Thanks for developing :) Is it possible to change video resolution to 1280x720 (or so) on this camera?

CHDK cannot change video resolutions.  Sorry.
