I am sure because the same pixel constantly appears on pictures.
but when I use CHDK, I can clean him from a picture.
and at the record of video he remains on the same place

It is not possible to get access to each video frame and then, in realtime, remove the hot pixel.

Maybe there is a plugin for VirtualDub that will remove hot pixels from the recorded movie ?

yes, it is possible by the use of scripts (please search the forum or open another thread). please refrain from double or triple posting.

about the hotpixel issue: like Microfunguy already wrote, it isnt possible (yet), and maybe never will.

A710IS:  when pressed half shutter while starting the camera crashes. Why? Latest collaborative autobuild.
Does the edge overlay work in A710IS?

Mine doesn't... ?/ Could have something to do with CHDK... (=I have no idea, try renaming cchdk.cfg.)

From what I've tested, doesn't seem to.

I got it!
The problem is zebra! If the "show zebra is on" the camera crashes, if the zebra is off, the camera doesnt crash.

My zebra config:
mode blink 1
under exp 1
over exp 1
refresh default view yes
refresh osd yes
draw over histo
rgb zebra off
..........

I will have a loo kto source.




--------

I looked:
is suspect this:
gui.c - look up a string "    if (conf.zebra_draw && gui_mode==GUI_M" and anylyze it

can it be debugged?

(edit: I don't have any problems with those zebra options...)


motion detection in Lua now returns the number of detected cells.

usage:
cells=md_detect_motion( a, b, c, d, e, f, g, h, i, j, k, l, m, n, o, p )
(h can be pretty much anything, it's there for compatibility with ubasic documentation)
(edit: every parameter is now optional, some of the default values are the same as in fudgey's MD scripts)

or:
cells=md_detect_motion( columns, rows, pixel_measure_mode, detection_timeout, measure_interval, threshold, draw_grid, ignored, clipping_region_mode, clipping_region_column1, clipping_region_row1, clipping_region_column2, clipping_region_row2, parameters, pixels_step, msecs_before_trigger )

Here's a patch that fixes the warning spew from lua, and another one in luascript.

You might also want this patch I posted for the trunk.

I've also noticed some issues with the fast video control stuff (mentioned on IRC, but posting here so it doesn't get lost):
It doesn't correctly detect when you aren't in movie mode. movie_status can be 1 even after you've switched the mode selector to a still mode (on my a540 anyway). This means that pressing left or right will still try to do the pause/unpause functions. To know if you are in movie mode, you need to check all of the MODE_MOVIE_ values.

Even when you are in movie mode, the unpause function doesn't know if you are actually stopped or just paused. This means that if you try to use the left/right after having actually stopped the video you still try to pause or unpause.

I'll post a patch for the first issue and some other cosmetic stuff, but I'm not sure how you can deal with the second one.

On my camera, the fast ev keys (up/down) also conflict with the flash and macro/mf functions.
