After more testing I found the SX40 also crashed on exit after releasing AE lock.
Is that just in video mode?  And if so,  in video mode when you have used Tv,Av,Sv overrides?  Or does it crash using AE lock in normal image shooting modes?

Just with this script - the cameras appear to need the 'TerminateAdjustmentSystem' call to avoid the crashing.
So probably not directly related to AE lock.

A question: do the registration functions initialize something vital, or could the used event procedures work without them when called directly (by address)?

I tried using the event procs directly on the G1X; but the camera crashes straight away.
Haven't investigated to see what the crash is, or tried other cameras yet.

Thx, looks like subject of further research then...

To answer my question, yes, they do work, but they need to be called with the 'even procedure' parameter passing method (i.e. call_event_proc() ). Registering them with RegisterEventProcedure (using their name and address) is possible.

An interesting find: the script does work on the ixus115 in its 'high speed' movie mode (this is one of the few dedicated movie modes on this camera, unfortunately it doesn't have a regular movie mode).

I did some more testing on the G1X, calling the event procs directly with C & Lua wrappers works; but only if FA.Create and InitialiseAdjustmentSystem are called first (and TerminateAdjustmentSystem called on exit).

If these are removed the camera crashes straight away.

@philmoz

I am just wondering, have you tested this out on your ixus310hs? If so, does this script work?

That makes me curious about the romlog. I'd prefer not having to register dozens of event procedures.

No, I have not had any success with the IXUS 310 yet.

It's an odd log, no stack or register trace.
It starts with:
Code: [Select]
ASSERT!! Head.c Line 3985
Occured Time  2014:01:27 11:08:41
ISR : vector=107
ShootConDump:
0f 0f 0f 0f 0f 0f 0f 0f 0f 0f 0f 0f 0f 0f 0f 0f
0f 0f 0f 0f 0f 0f 0f 0f 0f 0f 0f 0f 0f 0f 0f
CameraConDump:
07 0a 02 0d 09 01 0f 0f 0f 0f

Followed by the camera log.
