Low resolution, zoom out. High resolution zoom in. #1134

I'm using the old 5mp camera module and I noticed that when I lower the resolution, the preview and recorded video is zoomed out, while the higher the resolution, the preview and video looks zoomed in. What is causing that?

I experience something that looks like: When I choose a single camera as a full screen, I only see a smaller image, but as I finish, the full screen picture is displayed for half a second.

@norey that behaviour is not about zooming but it's rather the way the PI camera manages its view port under the two different modes (video mode and stills mode, as far as I know). These modes are changed at some resolution threshold and that's what you're experiencing. This is not a motion(Eye(OS)) thing, but rather a Raspberry PI camera thing.

@SuneBielefeldt your issue is (probably) different thant @norey's. Anyways, you may be able to fix this by playing with your layout preferences. How many cameras do you have and what are your layout preferences set to?

SuneBielefeldt commented 7 years ago

I use 10 cameras + 6 link to a friend's address remote from me, in total 16 cameras. My Motion Eye hub (Raspberry Pi 3) with Motion Eye Os release 20170827.

But you brought me on the track. I had configured 2 layout rows without understanding the meaning. Now I know it's important for display in single frame mode, full screen, but seen inappropriate, or what is the idea of ​​this option?. I first thought it was a consequence of the pre-release.

@SuneBielefeldt you're right, those prefs shouldn't affect the full-screen mode. I'll look into it and try to find a fix.

@norey sorry for hijacking your issue :)

norey commented 7 years ago

@ccrisan No worries man :) That looks to me like a bug in the pi camera. I don't understand the reason behind this behavior, do you think there is a solution for it? Never heard about this issue before, is it documented somewhere?

@norey http://picamera.readthedocs.io/en/release-1.10/fov.html

Look for FoV (field of view) and you might be able to find more details on this topic.

Thanks! :)

Another thing, is there a rotation feature for captured videos? (e.g. delete the oldest when storage is low) or should I write something up?

ccrisan commented 7 years ago

@norey not yet.

norey commented 7 years ago

Ok cool, then a simple cron job will do, thanks.

Any update on the Layout issue for Grid View vs. Full screen you mentioned on this thread as well as #679?

I'm having the same issue.
