Thank you for the great work!

My problem: According to the chdk manual half-press shooter + down should toggle the shutter override. But here it toggles the histogramm. Half-press shutter+ right button doggles the osd but not all symbols. Half-press shutter + up toggles nothing, so can some of this shortcuts remapped? Now I can not use the shortcut shutter override function, every time stands "no overrides" on the display.

You can set up everything from the CHDK menu, also the shutter overrides.
In the "Extra Photo Operations" CHDK menu set "Disable Overrides" either to OFF or DISABLED, read more about this feature here: Disable Overrides

The keys/keypress combinations you mentioned are just additional shortcuts for the menu items.

edit2: seeing that the patch actually gets downloaded, can you report if it works for your cam ? TIA
         PM me if you would like other binaries uploaded
@whim,
I haven't tried your patch as I have some problems with my main internet PC at present but,
when I did the first stage of the port I made a typo / mistake and set this up the way you have it now.

It does work but we "fixed it" as it was seen as a bug (non CHDK standard).
The only problem I can see is for users of multiple cameras with CHDK (what camera starts how).

If this is now changed will it not need to be documented in the user guide and on the camera specific details in wiki ?,
or you you suggesting an update to change all cameras?.

Unrelated question,
I have my card dual bootable working fine with CHDK, the card is locked in order for CHDK to start. I have taken a few shots that I would like to use the camera built-in "iContrast" function, under the Canon menu, I can preview the image but when I apply the changes it doesn't save it, I believe is because the card is locked, if I unlock the card, the camera won't see the images, so I lock it again and the camera doesn't save my changes, guys, do you know a solution for applying iContrast when using CHDK like this?
Thank you!

@OldGit

I was only trying to provide an option for people who can't live with CHDK's 'normal' behaviour, i'm not
suggesting in any way that it should be included in trunk (and won't use it myself)
That said, if enough people want it included (the option i mean, not the default behaviour !)
they could always try to convince someone in authority ...

I should probably move the post to a new thread, what do you think ?

sorry for the confusion,

wim

@whim,
I have always thought of you as "someone in authority" :D

I personally don't have a preference how the camera starts up, but as you correctly suggest, maybe this is one for a "global vote".
A new thread, for a vote by all users, I think would be a good idea.

Of course. But I just want to point out that something is broken in core/gui.c (or not ifdef for sx200)

67     #define SHORTCUT_SET_HYPERFOCAL      KEY_DOWN
68     // For models without ZOOM_LEVER  (#if !CAM_HAS_ZOOM_LEVER)
69     // SHORTCUT_SET_INFINITY is not used
70     // KEY_DISPLAY is used for gui_subj_dist_override_koef_enum;
71     // KEY_LEFT/KEY_RIGHT is used for gui_subj_dist_override_value_enum (because of no separate ZOOM_IN/OUT)
72    
73    #elif defined(CAMERA_g7) || defined(CAMERA_sx10) || defined(CAMERA_sx1)
...

But on KEY_LEFT the MF menu from Canon is shown (and it should be mapped to this key because of the MF text on the button), nothing changes on KEY_UP. Is SHORTCUT_SET_INFINITY and SHORTCUT_SET_HYPERFOCAL implemented on sx200? We can also use JOGDIAL_LEFT   and JOGDIAL_RIGHT when we are out of buttons. ;-)

- manual control over video recording: maybe shutter speed is a bit tricky, involving the limit of the framerate, but aperture control would be very useful for more creative use.

- 480p: if we go to 640x480 we lose 16:9 screen ratio (or crop to a small 640x405), a 720x480 could be nice.

- increase frame rate on lower resolutions video recordings: if we could have 60/50 fps with lower resolutions (as lower as necessary to allow the double rate) we could do some nice slow motion!
you can check on philip bloom website ( http://philipbloom.co.uk/films/dslr-films/kauai-sunset-lumix-gh1/ ) his beautyful tests with Panasonic GH1 60 fps mode

bump.. really no one is interested in checking the availability of those features? :(

AFAIK nobody has so far succeeded in upping FPS or resolution for any of the CHDK supported cams -
some forum searching - the term 'video FPS' is a good one - will give you plenty of reading material.

HTH,

wim

PS search box is your friend and saviour on a rather chaotic(?) site like this (top right of page)

Repaired "bad palette" during playback/canon menu...

sub/100c/lib.c
void *vid_get_viewport_fb_d()
should have 0x2950+0x58 instead of 0x2950+0x50.
