Is it possible to remove the code of chdk that controls video stuff?

I have an sx20 that does not like to have its video functions affected in anyway or else it causes intermittent problems (where it will often fail to record)

but i love having the other options that chdk offers.

A small change in boot.c to not intercept the movie_rec.c task should do it. Just a matter of commenting out one (or two) lines. But it will take a recompile and you will end up with a custom version.

Find platform/sx20/sub/102d/boot.c and change

Code: [Select]

if (p[0]==0xFF879084) p[0]=(int)movie_record_task;into

Code: [Select]

// if (p[0]==0xFF879084) p[0]=(int)movie_record_task;
In platform/sx20/platform_camera.h add the following as last line to remove the video menu:

Code: [Select]

#undef CAM_CHDK_HAS_EXT_VIDEO_MENU
Can you compile your own CHDK?

been away from chdk for a while, and haven't been into photography for a while either. been busy, but now want to get back to it some!

I followed these steps, it compiled no problem - but the chdk menu still has the video options in it.

I am currently testing to see if these code changes help or not....
