The drivers haven't changed - ExoPlayer and RTSP. I did find and fix some issues in the last release with keeping the video connection from reconnecting and it worked on my test devices (Reolink & Kasa cameras) and at least some others I believe.
Both drivers have updates available but they both require changing the minimum Android version which would exclude old Fire Tablets like what I'm running on.
If you have a higher end Android device or tablet, give this app a shot here. It's using different video drivers (JavaCV for Android). I also was able to add some other features like recording, opening the video full screen with no delay, zoom & panning in on the video

The reason for so many different drivers is RTSP video streaming support is a really mixed bag. I just went with the ones that worked the best in my testing.
I've thought about porting that logic to this new app but there's too many risks of breaking existing dashboards. Video drivers are really large too so I wouldn't want to add another 20 Meg to the apk size.
