@Caefix mentioned here https://chdk.setepontos.com/index.php?topic=14294.msg145525#msg145525 that ixus265_elph340 shows incorrect PTP live view when video recording is in progress.

Attached is a test build that will show some debug information when "misc values" are enabled in the debug menu.

A screenshot is probably the simplest way to report, but the values are:
srsa_4c debug display. The value we want is the number of frame buffers while video is recording.
MS: movie_status variable
VH: vid_get_viewport_height

It would be helpful know what video resolutions the problem happens with (HD or VGA)
Don't forget what the H stands for.

Thanks. Here's another test build.

Please post a screenshot with HD video recording, and not recording.

HD video might be fixed, but other things might be broken. Please check the different aspect ratios for still images (3:2, 16:9, 1:1)

It´s FHD only.  :)
From the manual, this camera has FHD (1080P) and HD (720P). I'd expect the viewport to be the same, but if it's really FHD only, let me know.

I'm not clear what your screenshots are showing.
The right image on chdkptp_20210409_173242HD.png looks quite incorrect. The image is shifted down, and looks like it's cut off.

The right image on chdkptp_20210409_173731FHD.png looks like the original problem.

If the display is wrong only for a short time while recording is starting / stopping (I guess that text on the 3rd image means you just stopped recording and it's processing), it's OK. If it's something else, please explain what was happening when those screenshots were taken.

We can try to fix ixus275 after this one.

:blink: Indeed. Yesterday FHD was flattened, today HD is stretched & shifted.
The left pics I´ve been pointing at the same place, the right shows the elongation...

So "Looks good now" refers to what? FHD only?

If it's true FHD and HD are different, please give me the result of
Code: [Select]
=return get_prop(require'propcase'.VIDEO_RESOLUTION)
with each setting. Video doesn't need to be recording.

If you need to include more than two screenshots, please just put them in a zip file, and in your post, explain exactly which settings were used in each screenshot. Like

chdkptp_20210409_12345 - recording video in HD
chdkptp_20210409_67891 - recording video in FHD

Don't forget what the H stands for.

Code: [Select]
=return get_prop(require'propcase'.VIDEO_RESOLUTION)VGA=2; HD=4; FHD=5  :)
Edit: Tried with Sx620. Same issue, Sx610 (n/a) probably too...
Edit2: Same with Ix240. Here the videobutton works on touchscreen only...  :-[

Before we can move on to other cameras, I need to understand what's happening with this one.

In the last test
1) Do HD and FHD look the same, or different in live view?
2) Does FHD look 100% correct?
3) The problems you see happen while recording, not just stopping / starting record?

The untouched cams have a nice HD & flat FHD.
The modified has oversized HD vs. 100% FDH.
3) ... while recording.  :)
