A590IS porting...

BTW i found the addresses needed for this function (_TurnOnMic & _TurnOffMic) are the same for 100E & 101B,
checked this in IDA disassemblies in comparison with A720 ...
The addresses were already present in the source for 100E, but not for 101B, which explains why the option
was switched off for the cam (CAM_CAN_MUTE_MICROPHONE is defined at camera, not firmware level)

NHSTUB(TurnOnMic, 0xFFC35CFC)
NHSTUB(TurnOffMic, 0xFFC35D2😎

i then changed include/camera.h to set CAM_CAN_MUTE_MICROPHONE = 1 for A590 and recompiled 714 for 100B

in case you're interested i attached it (note: build looked stable and produced the menu entry for me, but since i never
use the video options i don't feel qualified to say it works)

wim

edit: removed attach - it doesn't work.

Hi,
mmm imperessed how quick you are. 😎
but it seems for me, on my a590 101b, it doen't work. tried on 714 and 715.
just changed <DISKBOOT.BIN> from archive which you posted for the same in a root dir, then moved in video mode. zooming option is Ok, but sound is still on.

It seems that movie support for A590 is fully not implemented yet (sub_FFC64338_my in movie_rec.c not called from boot.c), therefore mute_on_zoom() even not called at video recording.
Question to camera owners: how about variable bitrate\quality in video mode, it works?

Thanks ewavr for clearing up why CAM_CAN_MUTE_MICROPHONE was undef'ed

My Camera A590is fw 1.0.1b video mode problems interesting, see my and others old messages for
zebra and video mode problem. Zebra problem solved, video mode not. Currently NOT! tested the latest autobuild, and the attached
probe chdk with mic patch. I will try this. In 709 autobuild bitrate, quality selectable, but not working, same size video recorded.
Optical zoom interesting, long time not working with my camera. I see new messages with good news in optical zoom. I will test too.

Crach, without this probe patch, i don"t know this problem solved, or no:

Video mode, bitrate, quality, optical zoom.

Now i tested the chdk ver. 715 on a590is fw 1.0.1b video modes.

Bitrate, not working, same size video recorded.
Quality, not working, same size video recorded.
Optical zoom, working, great!

Probe chdk same, ver. 714 with mic mute patch, but has option to mute microphone in menu.
Micropohe always working, not muted. and yes, focus system noisy.

Both version has an unkown option for me:
- Fast video controll
- af key (selectable set/shutter/none)
What good are these features?

Here is my contribution in testing CHDK in the A590IS:

When converting DNG->RAW (Selecting DNG in File Browser,
click 'Left' for popup menu) it adds a WAV file extension to the
RAW file it creates instead of a CRW extension. This should be
an easy bug to fix.

Also, Exif doesn't get copied either from the DNG to the new
created RAW file. Maybe it is not supposed to copy Exif
information with this option but It would be something nice to
have.

BTW, the new file loads fine in UFRAW if you change the
extension fom WAV to CRW but as I said no Exif data is copied
to the new created file.

Also, I can't find a way to turn the microphone off when
recording a videos. Where is that option so I can test it? I
assume it is not there yet.

How do you activate the ND (neutral density) option? If there is one.

I understand that some of the video option don't work just yet.

Thanks guys and keep up the good work! 😀

No bug here. If original file extension is CRW or CR2, new file extension will be WAV, otherwise it will be CRW.
You can use DNG extension for DNG files.

Also, Exif doesn't get copied either from the DNG to the new created RAW file. Maybe it is not supposed to copy Exif information with this option but It would be something nice to have.

CHDK RAW (CRW) contain no EXIF information.

dvip

Thanks ewavr

The original file extension was DNG and it created a WAV.
My intention was to create a CRW file with Exif information from
a DNG file in the File Browser, but I guess it is not possible to
have Exif information in a CHDK RAW (CRW) file.

I found it odd since WAV files are usually associated with
media players, that's why I thought it was a bug, I was expecting
a CRW with Exif from a DNG.

I will keep testing CHDK.

Thanks for the clarification.

I noticed that under yellow (incandescent) lighting I cannot produce same sort of picture out of raw/dng file as the camera jpg produces. I use Adobe Camera Raw to convert and it almost looks like it just does not want to go below certain values in the color temperature or above certain values in the "tint". Even if I use white balance adjusting tool, I still cannot get acceptable result.
Is this something known? Any workarounds?
If the picture was not taken in yellow light, everything seems to be working just fine (though tint values are still quite huge, but I guess this is some sort of the ccd artifact?)

Thanks. That explains some of it. What I find interesting is that since DNG write mode extracts proper color temperature and tint from the camera now, should not the result be the same now? It is the same for a lot of cases too, so is it just Adobe Camera Raw that is inadequate in that case?

dvip

I also open the DNG files in UFRaw and the colors and white
balance are fine, this is great!
But CHDK RAW still have a white balance problem when open in UFRaw.

Is there any way to create CHDK RAW files in the camera with the Exif
information found in the DNGs?

It is nice to have the DNGs load fine now.

What should we be testing now? The video options?

Please forgive me as I am relatively new to CHDK. Just noticed that AF is not functional for video regardless of the "AF key" setting. Is this correct for build 719 or am I doing something wrong? Also, is the mute on zoom feature possible for the A590is? Thanks

toby

Same with my cam...
I just downloaded the last build, and tried video.
The AF doesnt work, neither does the optical zoom ;-(

rotter

toby,
I think for the optical zoom to work you need to zoom out a bit and then begin recording. What I found works is if I forget and start recording at the default full wide, I push the zoom lever to the left (wide) twice and then optical zoom works. Takes some getting used to, but optical zoom is nice (albeit noisy til mute on zoom is available for the A590.)

toby

It still doesnt work with my cam.
What version do you have?

rotter

toby,

Sorry you couldn't get optical zoom to work with video. I am running CHDK build 719 and both of my a590is's are fw 1.01b. Have you tried zooming out before you start recording?

Hey guys, i just ruined my brand new A590IS out of stupidity. It fell from my hands and the lens got stuck. In my desperate attempt to fix it i broke some cables and now there's nothing i can do about it. I'm about to buy a new one, and if you need some pictures of the insides of the A590IS, for whatever reason, i'd be more than happy to supply you with some.

PhyrePhoX

mind you, before disassembling it you can always try to sell it on ebay. broken powershots sell for high prices on ebay these days (probably due to chdk?).
if you dont plan to sell it - hell, why woulndt we want pictures of the a590 innards? go for it 😁
