SX110IS - howto start porting

From step to step...
A new version of CHDK for SX110!

Optical zoom in video record mode works now.
Please test video bitrate settings.

movie_record_task() in movie_rec.c must call unlock_optical_zoom()
explicitly because SX110 doesn't support this feature officially (as SX10
does). Therefore no call to unlock_optical_zoom() was necessary in
SX10-code (which I've used as template).
BTW, all camera dependent code related to movie record looks very different
to SX10 so movie_rec.c needs some other modifications. I've changed also the code that deals with video bitrate and quality settings (http://chdk.wikia.com/wiki/SX110IS#Known_bugs). But not tested yet...

That's one of the main problems in this port. SX110 is somehow in beetwen
SX100 and SX10. Some functions have to port like this and other like
that...

Attached is an archive with a new Binary and an other archive with my code (for developers, based on r749).
If video bitrate settings works than I will ask phyrephox to commit a new release to the autobuild server.

Any ideas for "GetBatteryTemperature"?

all tested...
all works very fine 😀 also video bitrate settings! SD full after a few Seconds :lol
nice work!

all i can do is beta test and my only knowledge is on electricity unfortunately. I can modify my camera to real time measure battery's if that count and report back with info about the state of measures with and without CHDK.

If i can be in any other help please ask me to. I will be more than happy to do it.

The camera shut down completely with the change battery's info on screen after that.

What are you thinking: do we have a problem with the battery indicator?

I cannot speak without testing and have to sleep right now. I will do it tomorrow.

It does not seem as a problem with battery indicator (battery read data) since unloading CHDK keeps showing empty battery.

Somehow loading CHDK doubled the power this camera needs? Is this an option? Maybe more things works and thats why this happens?

I will modify my camera tomorrow and test with 4 sets of battery's. 2 sets of rechargeable and 2 sets on one use battery's.
I will test every set with and without CHDK and i will report any findings.

Might be that 😛
I might have been playing a loooooooot with it except just taking pictures. Maybe i lost the sence of time while i was doing that.
Pretty much this really might be the answer. Still since i have all the professional equipment to mesure things like that (thats a part of my job) i will do it.

I will test with just taking pictures and nothing more.

Thanks for the info mate.

by the way what is the normal way for me to unload a script and having none loaded? I haven't found such an option yet.

Hi
I installed the updated version.
Now i am able to use the Zoom in video.But i am experiencing focusing problem at 8x+ is it normal?
Like when i zoom above ~8x the screen is blurred and struggles to focus with no result. Although below 8x it is able to focus(not perfect, but acceptable). But At 10x its not Focusing! atleast for me.. any idea why is happening?
The object is my 29 inch television, about 15 meters away.

===edit===
I tested again, the cam is able to focus the nearer(1 meter distance) objects at 10x in VIDEO, but cam is not able to focus when the object is far( 10-15 meters) at 10x.

I have the same problem but I dont know wheather it is, because the camera isnt build to focus at video or because a bug <-- (dont think so), but i think its 1.

This is a video of Sx100 using chdk, zoom applied and it does do auto focus.
I think our SX110 might do auto focus aswell.

Sorry if youtube links are not allowed here.

I just tested the new release. Optical zoom now works in video mode, but I do lose focus after 70% or so.

Also, I changed the recording mode from Bitrate to Quality and the camera kind of crashed when I tried to record video. The screen turned off immediately and the controls would not respond, except the power button, it does turn the camera off. I could turn back on again, no need to remove batteries. Nothing was recorded. I tried three times, same result every time.

lol for me it works fine

Hey, I've been watching this thread recently...Great work!! For some reason, the latest version(s) don't work and the older version(s) did work. I get 'Update File Error!' when trying to load chdk (Menu, Up to the bottom, Set to select, then the error.). Any ideas? Thanks a bunch!!

Just checked the last copy chdkj posted here and can't reproduce the issue.

In Quality mode I think camera can't record to SD fast enough. Thats why I think it crushes. If you lower the quality to 98% camera will not crush! Also if video gets busy @ 98% it will crush as well.720is chdk had some kind protection against that. If your SD isn't fast enough for recording it just stops the recording. If you're right on the edge then warning sing flashes on the screen. Also with 720is I found out the difference between different SD card speeds. Generic cards will stop at around 50%. Better cards will go up to 84%. Excellent cards can go to 98% I have one SanDisk 1GB that can do 99%.

When you zoom 100% without recording, camera can focus no problem. But when you recording and zooming >70% then there is a problem. I think it's a bug.

Good hint. Will check this.

When you fully zoom without recording, camera can zoom no problem. But when you recording and zooming then there is a problem. I think it's a bug.

Did you mean the "Focus Lost" problem at zoom > 70% ?

I will check the code again.

Inferno

Brr... I'm drunk or what?!!? Yes I did mean can't focus >70% But when you're not recording, you have no problem focusing @ 100% zoom.

I still couldn't record at 98%, but it *seems* to have recorded at 97%. Large files are recorded (20 secs. = 105 Mb), but I can't playback them entirely on my Linux box. Mplayer just playbacks two or three seconds and closes. Sometimes it will play a few more seconds, but never all the way through. They playback correctly on the camera.

@Hyst
Could you explain what is not working, please? Auto-ISO-Shift works as
expected for me: ISO value changes automatically depending on available
light and so on... Am I wrong?

sure.. i'll explain.
Auto-ISO-Shift ist not the normal Auto-ISO. Auto-Iso-Shift works like this:

Rec-Mode -> menu -> activate auto-iso-shift.
go to P- TV- AV- or M-Mode -> change iso (for example) to 80 (should be a low number).
Go somewhere, where the light is not so bright (some kind of "darkish" area).
half-press the shot-button. Now the Print-Button should be blue. press the print-Button.
Now you should see how the ISO and the exposure-time changed to recommended (AUTO) settings.

SD Card speed. I have the same problem playing right from the card. You need to copy file on a hard drive and play it from there. (My videos,played from sd card, don't crush a player but they can get jerky and sometimes loose audio). It's all about card speed.

lucmovel

No, you got that backwards. I can play it fine on the camera, I can't play it on the PC. EDIT: I mean, I copy the file to the HD before playing it on the PC.

Okay, that one works, I was using the one from the Autobuild server. Thanks.

nycjv321

ok possible bug
I have 2 partitions
/dev/sda1 'fat16, 1536megabytes
/dev/sda2 'fat32, around 6000megabytes

chdk boots and automatically switches to the second partition when I go into menu to switch it to first, it doesn't is this default behavior???
also optical zoom doesn't work (after recording starts) with latest build right? and doesn't work regardless without chdk (zooming works before recording atleast right?

thank again for hard work 😁
