I wasn't sure where to post this, so I'm posting it here as it probably qualifies as a bug.

There is an issue affecting cameras that can record video in non-video modes.
When recording multiple videos without switching the camera off, the CHDK bitrate / remaining time display gets more and more incorrect with each recording.

I believe the logic inside gui_osd_draw_movie_time_left() (core/gui_osd.c) fails for recordings made in modes other than video.

The following patch seems to help, although I'm not sure it's optimal and without side effects.

Code: [Select]

+#endif
 }
 
 void gui_osd_draw_ev(int is_osd_edit)

I first noticed this while working on the D6 movie support code, but managed to reproduce it on my Ixus115.
Can somebody with a dedicated movie button camera confirm the issue?

I see something similar to a sx410 camera.
The remaining time after a dozen recorded clips starts to grow instead to falling.
Much stranger things happen if I delete the last recorded clip.
After deleting of the last recorded video,for the remaining time and data rate are displayed completely wrong data.
Regardless of the incorrect displayed data rate (KB/s), the size of the recorded file corresponds to the settings for the desired bitrate.
With the restart of the camera everything returns to normal.

Good find. I confirmed this on elph130, and the patch seems to resolve it.

I don't see any obvious problems, but the but moving the record_running logic before the main if might make it easier to follow, as in the attached.

Thanks for both of you. Meanwhile, I could confirm the existence of this issue on an old S3 IS too.
@reyalp
I'm OK with your patch, please check it in (both trunk and 1.4, I guess).

Some kind of millennium bug?

shooting.c line 41
typedef struct {
short av96;
short tv96;
short sv96;
short subj_dist; // should´t such values be int for newer /hizoom cams?
short nd_filter;
} PHOTO_PARAM;

Nice?
D:\hostluaPortable\CHDK-Shell\trunk\trunk-5279\platform\generic\wrappers.c
line 263 : _MoveFocusLensToDistance((short*)&newpos);
lolevel.h line 22
extern void _MoveFocusLensToDistance(short *dist);

Thanks. I checked in a fix as mentioned in https://chdk.setepontos.com/index.php?topic=13875.msg141593#msg141593

This should not be a problem. Some firmware _MoveFocusLensToDistance may expect a short, others an int, but the pointer will work for either.

Test/filetest.lua now prints always something.

Code: [Select]

--[[
@title file browser test
@chdk_version 1.3
]]

function restore()
play_sound(0)
print(f or "not f")
end

f = file_browser("A/CHDK/SCRIPTS") or "<Folder!>"
play_sound(5)
print(f)

Found my infrared Ixus300 with #5163

Something happened on the road to #5285 (#5229?), the oldest versions I archived.
Using pure #5163

Code: [Select]

--[[
@title file browser test
@chdk_version 1.3
]]

f = file_browser("A/CHDK/SCRIPTS")

print(f)

returns the expected nil, the later breaks script if folder chosen with "menu"

Edit2: Suspicious zone:

fselect.flt[5205] repairs #5229.
Edit: Not missing:
