Sorry, my inexperience with svn, I have added filewrite.c.  Hopefully this patch is up to standard :)
I do regularly update my svn copy to the latest version.

From a quick look, this one seems fine. Will try to add it tonight.

Oops, that part was my mistake, I was looking at the wrong file when I made the comment about versions :-[

So what to do now? I made a skeleton movie_rec.c from capdis of task_MovieRecord and stuck in various LogCameraEvent to see what happens in the branch table...
It seems that it is always for start recording case 0, followed by one of cases 2,4,7 (all same address), followed by stop recording case 1, case 2,4,7.
Haven't nailed down bitrate at all, tried monitoring two different memory locations, but I'm not sure really what to look for, likely addresses in the code are near 0x13a60 and 0x13ae0:
Code: [Select]
0x00013a60 64superslomo or standard 30fps

I have also done something similar, but stopped when I found out that most of the compression (and multiplexing?) related code is likely not running on the ARM core.
That makes the whole movie related code completely different on DIGIC 6, and needs original research.

Has any of you experienced rare crashes when using a larger number of exposure overrides? Here's an example. An sx520 user is reporting about these, and I can't find an explanation. The code path causing trouble exists on all new CMOS models (including the sx60 and g7x).

I tried a couple of shots with the settings shown in the link.  Flash up. No crash. Fairly dark setting came out bright.  Is the crash associated with severe over exposure?

Thanks for trying. Unfortunately, only few details are known, and the reports come from a single person. Here's my related post.

I'm having trouble finding a lens profile for the SX 60 HS. I could build one using lensfun I suppose, but I can't find it using Adobe lens profile downloader. Anyone have a suggestion?

Hi to everyone,

I am from Croatia and I am new to this forum and I joined because I am the owner of Canon SX60 HS and I really like the camera. One of the reasons I bought it is because I wanted to use it to shoot timelapse videos.

I tried your pre Alpha release and I can tell you that intervalometer script works just fine. Disabling of dark frame substraction is also working and I am very happy with that. But, there is one strange thing which happens sometime. Sometime the camera is taking pictures rotated for 90 degrees clockwise. I found that if I first take only one picture without activating CHDK and after that if I start chdk then pictures are taken in proper orientation.

Firmware is 100b and I am using intervalometer script which is already inside the chdk. I am also shooting only jpeg, not raw.


Any suggestions are welcomed and if I can help somehow in process of porting CHDK to this awesome camera just let me know.

Regards,
gile2004
