the build is from http://www.mighty-hoernsche.de/trunk/ maybe some compiler bug on the server? (if I compile vanilla trunk with gcc452 on linux x64 I get the same crash)

However I tried building locally without those defines and still works (latest trunk)


edit: canon settings are P mode, AF center and everything else OFF

ASSERT!! FocusLensController.c Line 1059
Occured Time  2013:01:16 20:37:40
Task ID: 13238302
Task name: PhySw
That looks like the set_focus related assert that shows up on several cameras.

@c10ud @nafraf
You may want to do the set_focus test. Perhaps the results vary on a per camera basis...?
CAM_USE_ALT_PT_MoveOpticalZoomAt is most probably needed to get correct JPEGs after set_zoom (see comment in platform/generic/wrappers.c lens_set_zoom_point() ), and CAM_USE_ALT_PT_MoveOpticalZoomAt needs CAM_USE_ALT_SET_ZOOM_POINT to be effective (again, see the above mentioned source routine).

edit: spelling...

my set_focus tests results are the same posted by c10ud

set_zoom() tests:
With code from trunk,   if Continuous AF ON, camera does not crash, else, it crashes.
Removing CAM_USE_ALT_PT_MoveOpticalZoomAt, and taking photos at zoom 10 and zoom 40, I have not seen any distortion in JPEG.

@c10ud, have you seen any distortion?

I took pictures of my desk but I don't see any distortion...should I?

However I also checked exif with all defines disabled and looks ok

If there is not distortion, I think that those #define can be removed.
After removing CAM_USE_ALT_PT_MoveOpticalZoomAt, I tested this , I did not seen problem with this model.

@srsa_4c, is there any other zoom test to do? Thanks

Good question. There's several variants of a zoom torture test from waterwingz (linked from the thread you just linked): set_zoom problems in uBASIC & Lua scripts, someone could write a simple (and short) automated test based on those. There's a chance that cameras will crash while running it though, even when the port is OK.
Perhaps we should collect testing methods (automated or manual) in a thread before messing up the Testing wikia page...?

Something else: months ago we have shortly discussed a workaround for new cameras which don't have a proper MakeAFScan function, you may want to try this kind of workaround (needs a defined CAM_AF_SCAN_DURING_VIDEO_RECORD in platform_camera.h of course).

What happened with the previous post about A1400? was it deleted?

I did a test of zoom function: set_zoom()

camera crashes for
set_zoom(0)
set_zoom(5)
(for example)

and it works ok if you move zoom by 1 step increment:

set_zoom(0)
set_zoom(1)
set_zoom(2)
set_zoom(3)
set_zoom(4)
set_zoom(5)
...
