Multi-View Video Player

[jwinarske]

Only a single instance of Video Player is currently supported. The static plugin needs to be refactored to handle multiple views.

Currently a low priority.

Hey! Thanks for reporting that, we currently have an issue somewhat feels related to that but not entirely sure.

We have multiple VideoPlayerController's that are initialised at the same time and when the first video ends and the second one starts playing we get this exception:

══╡ EXCEPTION CAUGHT BY SERVICES LIBRARY ╞═══════════════════════
The following FormatException was thrown during a platform

When the exception was thrown, this was the stack:

that looks entirely like a Dart back trace. What branch and commit are you running on, and what package commit of video player?

Also note multiple video players are not currently supported on main or agl branches. It requires some re-work of the gstreamer plugin code.
