This version should fix zoom bug.  Please test it and report.
The ver. 100e  is working with and without digital zoom too.

New version, prealpha06, this version adds to Video Parameters menu:
Mute During Zooming Enable [●] / Disable [ ]
To eliminate focus mechanism noise if zoom is used during video recording.

Please test it and report

@marcelix: Thanks for feedback.

No nafraf, I finally got around to cleaning up my code ready to send in, only to find you've done everything I have and more in the meantime. Very sorry for the extra work you've had to do, I feel quite bad for sitting on the code like this :(

To try and make myself useful, I have compared the a2400 files from SVN to my versions and found a only one difference:

platform/a2400/sub/100d/stubs_min.S
I have the following:
Code: [Select]
DEF(enabled_refresh_physical_screen,    0x39D4 + 0x10)  // a2400: sub_FF896DF0 (0xFF896DF4 + 0xFF896E10)

which seems to be in most other firmwares, but isn't in your stubs_min.S. Does this matter?

The focus stacker script I'm using is just a subtle tweak of http://chdk.wikia.com/wiki/UBASIC/Scripts:_macro_DOFstacker to add an option for adjusting the size of the focus step between each photo. (taking 750mm of photos at 1mm/photo can take a looooong time).

Some of the resulting photos are here: http://utrainia.michael.net.nz/10-a-great-way-to-end-the-day. These are photos of my model train set, the trains are the size of my fingers so CHDK + a focus stacker script is perfect for my purposes :)

I have tested your latest compiled a2400/100d firmware and it runs without any problems on my a2400. I did just a very quick test that photos and video work, as all the important parts of the code are unchanged from what I had cobbled together.

Thanks for all your hard work. The a2400 is a great wee camera, but 1000x better with CHDK on it :)

Just done a test video here on a2400/100d; works perfectly. Very slight pop when the audio cuts back in again, but nothing unexpected.

enabled_refresh_physical_screen is used in some cameras (A1100, A3000, and others) , you can see it in  vid_bitmap_refresh() function.  I'm not sure if it is necessary in A2400, is CHDK interface working well in your A2400?

Nice train, and nice shoots :)  It seems to require a lot of work.

If you don't find any issue, I think that a2400 can be added to autobuild as beta. 
Another tests were done by marcelix, and they passed succesfuly.  I'll submit the patch in a couple of days.

Did the following test between my firmware and yours:
  • Insert SD card
  • Turn on camera
  • Enter alt mode
  • Open CHDK menu
  • Down one menu item to Video Parameters and open menu

Running your latest pre-release a2400 firmware, the Video Parameters menu opens and draws itself, then within half a second it momentarily flickers and redraws again.

Running my firmware there is no flicker. Not sure if it is related to  enabled_refresh_physical_screen or something else.

Hope that helps.

I included enabled_refresh_physical_screen and it is used inside vid_bitmap_refresh (as done in A3000).  If you want to check the code, it is available in my personal svn repo.

Please test this version and check if  flicker continues.

Thanks for the dump.
CHDK for a2400 100c is attached.  To load it, it is necessary to use bootable sd card method.
Please test it and report.  First test set: http://chdk.wikia.com/wiki/Testing

By the way, I have not got feedback about interface flicker issue
