but where is option to make mike mute to reduce noise? disappeared

In source code (714, @ include/camera.h) it says (for A590):

CAM_CAN_MUTE_MICROPHONE = 0  // Camera has no function to mute microphone

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)
Quote
NHSTUB(TurnOnMic,      0xFFC35CFC)
NHSTUB(TurnOffMic,      0xFFC35D28)   

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.  8)

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?

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?

@wim
@ewavr

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.

CHDK RAW (CRW) contain no EXIF information.
