I have made some changes to the port in changeset 4623. These were needed to make a port for sx520 with minimal differences.

About movie features: I got bitrate and quality overrides working in the ixus150 port, it will likely be possible to port them to this camera.

Video features are not supported.
Attached is a patch for movie bitrate and quality control. Untested, can't guarantee that it will work (firmware routines have a number of differences to the ixus150 ones).

Uhh man,thanks!!!
You saved me a few days of digging in the firmware, just today I started that job, and now I see that you have already made.
It seems that everything is working well, thanks again.

Hi! Can someone please tell me where can i find the CHDK firmware for the sx530hs and which features are working and which are not for the sx530hs (is there a list somewhere?). Is it safe to install?

Thanks

Hi !!
Two posts above is the CHDK for sx530 with firmware 100c. If your camera does not have firmware 100c, do not use it. To determine the version of the firmware you can use this application:
http://www.zenoshrdlu.com/acid/acid.html
CHDK for sx530 is almost fully functional, but the bugs are still possible.
In relation to safety, CHDK is a hack so there is always a certain risk. The risk is quite small but if you are not willing to accept a small risk, not using CHDK. It has to be your decision.

I tried to implement CAM_AF_SCAN_DURING_VIDEO_RECORD, but additional AF scan can be made only once.
I found NHSTUB (MakeAFScan, 0xff220228). The code in this part is pretty different than in older cameras, but I'm pretty sure I'm in the right place.
Camera after AF scan still working normally and video is further recorded without problems

I think a similar problem was found on A810 port, maybe you can check A810 port to know if the same workaround can be used.
