话题: letterboxing doing anything ?
NicotuxHome userMember since 2014
look like letterboxing is once more not efficient (don't know from which build)

bars : depending on ratio add black bars all around the image making it ....
- disappear from output window; top bar taking all the output size
(when no bar would be needed in one of the direction bars are forced everywhere)

crop: zoom the image at top of the window cutting the bottom only
- shrink the image at top of output window
(crop shouldn't cut top as well as bottom, and cut right or left instead of shrinking)

zoom : does not zoom vertically, but crop instead
- zoom horizontally but keep image locked on top of output window
(zoom should zoom in both directions)

maybe at least options to keep ratio and centered ?

You'll have to be more specific on the steps taken, since it works fine here.

bars only adds bars when needed, and they are equal at both sides
crop cuts such that equal parts are cropped from both sides
zoom always shows the full image stretched to fit the image

(test with loading video to deck and resizing output, tried with both video skin and without)

yes didn't notice at first but in fact this is videoskin dependant
without a videoskin in action there are not these issues

but with a videoskin (tested some i.e. broadcaster GFX - EDM or Disco and the new one I just uploaded
) this is really a problem but other broadcaster GFX - and custom Vintage View are not affected
most "standard" are not affected either

bars are added on top while image is cut at bottom or cut at top while bar added to bottom
crop and zoom are same add bar or cut top only

need to investigate more deeply in a way to detect the origin of the issue
but it seems this is affecting some <video> element in videoskin

I see now, the problem is when the video output aspect ratio is different from the aspect ratio of the video element in the skin.
In practice I don't think it would normally be a problem though. (the video element is 16:9 in the GFX - EDM skin, so when used on a 16:9 tv/monitor the problem does not occur either)

Edit: The issue is also only noticeable with bars (and still bars are symmetrical)
Zoom would still correctly fill the video element, and crop will still crop it symmetrical to fit the element.
The only way I could see a cut off image is if resizing the output window to a completely different aspect ratio than what the video skin is designed for, but in this case it's the video element itself that's actually been moved outside the screen, not the letterBoxing that is the issue.

That is it
it look like videoskin elements do not all resize/move the same way the main video does, specially texts and video visuals
fond a simple way : removing not necessary video element fixed the little skins
uploaded again
thanks
