Choppy Video/GUI - Android

[fuzelet]

Bug Report

Description

I have noticed that while using the Android version of the application, it stuggles to show 15fps webcams and the overall GUI seems rather choppy. When viewing the exact same printer in the iOS application, it is easily able to render 15fps webcams and the GUI seems snappier. Is there a framerate limiter or something in the Android version as it relates to overall app responsiveness? I stuggle to view 15fps streams in the android version without constant hiccups and fps drops even down to 0.01fps, where as I am not seeing the same on the iOS application.

Steps to Reproduce

1. Add Printer
2. Add Webcam
3. Android App becomes super choppy over the course of a print or after opening/reopening/using phone, requiring closing/reopening, etc multiple times over
   4a. iOS App does not appear to behave in the same manner and is displaying webcam and printer fine. can even display 30fps webcam streams fine

Expected Behavior

Android application to be able to view 15fps streams, even 30 fps streams without the application hitching or "lagging"

Hey,
what kind of webcam are you using (Mjpeg, Adaptiv Mjpeg, WebRtc...)?
Also what is the configured FPS and Resolution of that cam within crownsnest?

The provided GDrive link is also locked/private.

[fuzelet]

Hey! Webcam is set to MJPEG-Streamer. It is 15 fps currently in crowsnest and set to 1920x1080. I have also tried 15 fps with1280x720, 30 fps and 1280x720, 30fps and 1080, etc.

The link permissions should be fixed now. Sorry about that.

here is another video on android of the printer "homing"

here is the same printer doing the same action on iOS

I understand there will be some some choppiness given wifi, video compression, 15/30 fps, etc but im hoping these comparisons show what I am least experiencing currently on Android and how it seems to be choppier then the iOS counterpart

Thanks!
I will have a look to see if I can reproduce that issue. My assumption is that on the native end Android takes longer to process the MJPEG stream. Therefore, can you try the "Adaptive Mjpeg," which just queries screenshots of the webcam to see if that helps?

Thank you for the suggestion. I messed with the webcam and changed to adaptive mjpeg and tried various settings such as 30fps varible, 15 fps, but it still seems to struggle. I included another video below showing android is only doing 5/6 fps on adaptive 15fps webcam.

I did adjust the camera to 720 and restarted crowsnest, however android was still only showing 6/7 fps even on 720, so i dont think thats the issue. I can take a video of that as well if you need to see it,

Sorry for my late reply, 1920x1080 can be rather demanding. Also the Pi itself tent to struggle (Just open your webinterface multiple times and you will notice that the FPS drop.).
I will try to see if I can improve the adaptive implementation of MJPEG but if the PI/Network is to slow I can't do much about it right now.
