Thanks.

That looks "correct" to me. It's not perfect by any means, but it's using the right palette type and the colors are approximately correct. This is pretty much the same as what I have on a540.

One issue I've noticed (same on a540) is the left most column is grayscale on the camera display. This must be a special case in the Canon firmware.

The saturation and brightness of the other colors is off a bit as well. (edit: and a few colors are quite far off, e.g. the purple at 11,3 is blue on the camera)

I do have a note to go back and look more closely at the stuff rudi posted in https://chdk.setepontos.com/d/2361/860 at some point.

- The overlay colours are very strange: the grey gradients become rainbow coloured.

This is expected until the palette functions are implemented.

I implemented the palette and bitmap buffer functions for ixus100 in reyalp-ptp-live changeset 1710.

Untested, but looks quite similar to d10, so it might be OK.

Uploaded snapshot r219. This adds support for the type 3 palette, used by d10, g12 and other more recent cameras.

Hi,
I'v made test with -r219_-r1711 reyalp's last releases.
In expanded "view" when some sheckboxes are checked, it's a bit otside of my monitor.
But let the snapshots speak.
Fine job Mr.Wizard !

It does not matter, it was a minimal problem which is missing in r219.
The only problem which I see now is that what can not open the Camera folder, if the recorded video.

Hi again,

Get a bigger monitor 😉

Seriously though, I'll try to add an option to scale the live view area to fit at some point.

OK. I did fix a bug with the last color in the palette not getting set right.

Can you explain more ?

When I record an AVI file (set the mode dial to Movie), I can not open the folder called "Camera" in the Files menu.
I must restart the GUI and camera, and then the "Camera" folder opens normally and can download AVI from 100CANON to PC.

There may be some messages in the console window which would help understand what is failing when you try to open the camera folder.

Trying to build this myself, now have Ubuntu 10.04 and everything compiles and runs, but the live view doesn't work. I've enabled all the libs, installed, linked and checked the paths. When connecting however, I get the following stack trace:

/home/joel/chdkptp/trunk/lua/chdku.lua:950: attempt to call method 'get_handler' (a nil value)

Where do I look? All functions except for live view work however.

You need to set LIVEVIEW_SUPPORT=1 in config.mk

The fact that this resulted in a runtime error is a bug, which I've worked around in r226

Ok, thanks, that was the trick, now have it working under Linux (after also copying live_view.h from your CHDK branch)

So do you just need to copy that file to the main trunk build ? Or do you need to use the reyalp-ptp-live branch built for your cam/fw to use live_view ?

You need to use the reyalp-ptp-live branch, and the live_view.h included in chdkptp must come from that branch.

Thanks - wondered about that after reading the previous post. Any plans to add to the dev trunk ?

Note that the palettes types are likely wrong, but I can fix this if owners of the cameras send live view "quick dumps" and pictures of the camera display.

@reyalp : Got live-view working tonight under Fedora 16. Very nice!

A few rough patches to be expected I guess. The CHDK menus seem to overlay each other. If the previous menu is bigger than the new menu, you can still see it in the background. Pretty much what happens during the early stage of a port when vid_bitmap_refresh() is not working.

Here's the two image files for the G10 : http://www.box.com/s/6100778e4164ad695df7

If you can find a few minutes to "fix" the colors, I can use this to update the new USB remote wiki pages - the current images are pretty lame.

Thanks again.

Yes, holding off on that until after I've got the protocol changes sorted out.

At some point I plan to link in libjpeg or IM so you can save camera screenshots directly to an image file. Not today though...

Nice feature. Screen capture from what we have now is a huge step above taking pictures of the cam LCD with my cellphone but that would be even nicer.

New snapshot build r230. Not much end-user visible stuff. Changed the linux build to not use a really old hack related to the USB API, which should make it work on newer distros. Thanks to waterwingz for helping to sort this out. Users over very old distros (2005 ?) might want to look at http://trac.assembla.com/chdkptp/changeset/222 if they trouble.
