VideoController class

VideoController

VideoController is used to initialize & display video output. It takes reference to existing Player instance from package:media_kit.

Passing VideoController to Video widget will cause the video output to be displayed.

late final player = Player();
late final controller = VideoController(player);

Configurable options:

1. You can limit size of the video output by specifying VideoControllerConfiguration.width & VideoControllerConfiguration.height.
   • A smaller width & height may yield substantial performance improvements.
   • By default, both VideoControllerConfiguration.height & VideoControllerConfiguration.width are null i.e. output is based on video's resolution.
2. You can switch between GPU & CPU rendering by specifying VideoControllerConfiguration.enableHardwareAcceleration.
   • Disabling the option may improve stability on certain devices.
   • By default, VideoControllerConfiguration.enableHardwareAcceleration is true i.e. GPU (Direct3D/OpenGL/METAL) is utilized.

Platform specific limitations & differences:

Android

• VideoControllerConfiguration.width & VideoControllerConfiguration.height arguments have no effect.

Web

• VideoControllerConfiguration.width & VideoControllerConfiguration.height arguments have no effect.
• Only single Video output can be displayed for a VideoController. Displaying multiple Video widgets with same VideoController will cause only last mounted Video to be displayed.
• VideoControllerConfiguration.enableHardwareAcceleration is ignored i.e. GPU usage is dependent upon the web browser.
