I have some stereo display and image processing features that I like.
Interesting.  Is there a link to show what was done or what features were made available ?

I guess I am hoping that someone who found this bug will remember what he/she did.  Strange that it does not happen for 4gb.
The problem could be related to the speed/class of the SD card more than the size.  Or it could be a vendor difference.  Or a hardware thing.  If you knew what was fixed,  how would you use that?   .. sorry .. just curious ..

Hi,
I thought it might be a speed thing at first so I bought a faster card.  Nope.  In fact I checked with the old card with CHDK disabled and it worked fine.

I wrote some code that can display stereo pairs:
http://chdk.setepontos.com/index.php?topic=1253.msg13557#msg13557

I also wrote code that does some image processing.
http://chdk.setepontos.com/index.php?topic=2727.msg25535#msg25535

The stereo stuff is useful, I don't use the image processing stuff much.  Maybe Microfunguy has implemented the stereo stuff in his SDM build.

Of course, your code is in all builds and works in most.

It has been tested for SX150is.

Beta test version available using ASSIST  http://www.zenoshrdlu.com/assist/assist.html

If you have any problems, contact me directly.

Looking at your video,  you are doing everything correctly and you are clearly not able to disable dark frame subtraction.

I noticed that you put the camera into "M" mode so that you could override the shutter speed with the Canon controls.  What happens if you put the camera into "P" mode and use the CHDK overrides to extend the shutter speed instead?

For everyone interested thanks to Torsten Bronger (and in much minor way to the pictures i made) there is now a profile in lensfun library svn, for both raw and jpg distorsion and for raw ca.
Unfortunatly i can't do vignetting because of some dirt in the sensor, and i really hope Canon will fix the problem under warranty, it's not my fault is dirt or oil gets there...

The xml is here:

( This is also a problem with SX150 IS only in the ver 1.3 the problem does not occur in stable version in SX150 )

Was this reported somewhere else? If not already posted, a romlog might be helpful.

Not sure.

My test with SX150IS sx150is-100a-1.3.0-r3756-0
(i) only local change to kbd.c to allow concurrent usbremote / ptp.
(ii) No overrides
(iii) M mode
(iv) = set_zoom(100) sent from chdkptp gui -> zoom occurs followedby crash

Quote from: reyalp on 14 / December / 2014, 15:35:55
Is the camera in auto focus mode in the canon firmware?
> =return get_focus_mode()
4:return:0

Quote from: reyalp on 14 / December / 2014, 15:35:55
Can you check in the Canon menu if Continuous AF or Servo AF is enabled? (If the camera supports either of those)

Both Off

Quote from: reyalp on 14 / December / 2014, 15:35:55
The CHDK code tries to re-focus after setting zoom, so it's possible that the SD override changes are related to this. 1.3 will be the stable branch soon, so it would be good to get this resolved.

romlog attached / thread bookmarked.

Update:
MF (via lua post_levent_for_npt("PressSw1AndMF") followed by set_zoom also crashes.

For the set_zoom crash, try adding
Code: [Select]
#define CAM_NEED_SET_ZOOM_DELAY             300to platform_camera.h
The delay is in milliseconds, some cameras may need more than 300.
