The lower cost Powershots like the IXUS145 do not have an adjustable aperture.  However, the reported f-stop setting will change with zoom lens position.  It will also change if the interval ND filter is engaged.

sorry 4 stupid question....

That was not a stupid question at all. Many people have asked the same thing.  I actually had a somewhat famous camera reviewer basically call me a liar for pointing this out.

The Canon firmware will save a JPG image of every shot. CHDK will save the RAW or DNG file of the same image.  So there will be two files for each shot you take. 

If you are using a USB cable to transfer images from your camera to PC, you may now be able to see the RAW/DNG files. Try using an SD card reader.

Note that RAW/ DNG images can be stored in different locations on your SD card, selectable in the CHDK RAW menu.

Checked and fixed this. Interestingly I had to fix the active_viewport_buffer address to get the debug info working first and I think the reference I used (ixus145) also has a wrong address for it.
Thanks for noting that. I'll try to find an ixus145 owner to confirm.

@Caefix
Here's a test build. Please check the viewport debug "worm", with video recording and not, and also 3 values in misc debug value: AVB, CVB, OVB.

If they change too quickly to see the individual values that's OK, but if you can report if lit looks like they go 0-3 or 0x40xxxxxx or something like that.

You can also check the usual live view dimensions.

Thanks.

AVB starts with 0, OVB 768

then  00000000...
AVB. 4290414096
CVB : 0x181754
OVB : 262912    or  33817344
... never changing.

The (rec)-Icon is not always displayed in ptp.
After 1st videorec the SET-menu is broken...    :-[

Edit: Sec. run, different values ... :blink:
Edit2: 3rd & 4th run, started from the plug, values stable since the 2nd,
but always different "framerate", this times 2025 and 4324 ...
Edit3: ...and FPS 1454 with OVB 262912 ...
FPS seems random; <menu> in chdkptp live view only visible with UI-Overlay switch.
