is there an automated way of finding out, perhaps? :D


May be... :D

you truly do know your environment well. asm, c and even shell. thanks!
have you read my last question in my last post too?
good thing with me being so stupid is that other people too scared to ask the same questions get their answers ;)

next question: what about cams that dont have movie_record_task (like a650)?
if they dont have the variable declared in their stubs_min.S, what happens if i make the check like
In that case you should declare this variable in other way (i.e. as int variable in C-file and assign it with 0). Otherwise, it will not compile.

sorry to need help again:
Quote
int movie_state()
{
    return 0;
}
in a650's lib.c will throw error  at compile time
Quote
lib.c:65: error: 'movie_state' redeclared as different kind of symbol
../../../../include/platform.h:423: error: previous declaration of 'movie_state' was here
which kinda makes sense too. how do i avoid that again? :D

edit: funny thing is, if my feature will ever make it to trunk, i cant even claim it is written by me :D

Nope. :)
You need just a variable.

int movie_state = 0;

For A650 this address is 0x5518+0x38
A720: 0x5538+0x38
IXUS860: 0x54E0+0x3C

upd: the same "4" value during video record.

seems to work. however when i compile a720 or sd650 it throws an error like this:
Quote
conf.o: In function `conf_change_alt_mode_button':
conf.c:(.text+0x144): undefined reference to `kbd_set_alt_mode_key_mask'
this isnt related to movie_status though. probably related to not being up to date with trunk?
