Hi,I will look at the sx60 stuff.
I want to modify the image shown: for instance show a stereo pair using side by side or anaglyph or do some image processing on the image, like sharpen it. This used to be possible in CHDK.
I can write to the buffer vid_get_viewport_fb_d(). This works fine (at least the buffer can be modified, I am not sure of the colors) for every second displayed image. What do you mean by "full color". For the bitmap?
Is the viewport encoding not UYVY 4 bytes for 2 pixels? Is the color a different format from the old UYVYYY format? I think I am seeing this.
What should I change? maybe: u = (unsigned char) src - 128?
Why would Canon change this?

Do you know if the migration is easy to do - if you explain it to me, I could be able to do it. I could not find how to switch from 100c to 100d for my G7X either. AFAIK you're the first person reporting a 100c firmware revision. Please make a dump of your camera's firmware: http://chdk.wikia.com/wiki/Canon_Basic/Scripts/Dumper

Hello. With a little delay, here is the firmware dump https://drive.google.com/open?id=0B3QGa8gm4F_TMEhtVFVBaUluTHc
I've tested with the Update firmware menu when starting camera in Play mode, and the green led blinks continuously without ever showing the chdk logo.
I've also tested the "lock sd card" install, but then the camera starts in normal mode, and says the card is not writable. Thanks a lot!
The big problem is how to find out which one the camera is using. Any suggestions how to find this out?
0x5e208000; // used for 2nd unzoomed display and every other after (unless a zoom happens)not used for zoom, pans (as far as I can tell)0x5e608000; // used for 1st unzoomed display, some zooms, pans0x5ea08000; // some zooms, pans0x5ea08000; // some zooms, pans
Another way to check is to turn on the histogram display. The histogram it displays may be wrong, but it does reflect the buffer data it is accessing.
I am using trunk 4685
