The ITEC MediaPlayer library is a lightweight VideoView/MediaPlayer replacement for Android’s default components, enhancing it with exact frame seek, playback speed adjustment, GLES shader effects, picture zoom/pan by gestures, and DASH support.

Spectaculum is a view widget for Android to display visual content in a GLES accelerated context, providing zooming and panning functionality, parameterized shader effects, and frame grabbing. It comes with additional views that save developers a lot of time and implement all functionality for displaying bitmap images, camera preview, and videos through the Android MediaPlayer, MediaPlayer Extended, and ExoPlayer. The packaged shader effects range from simple color filters to immersive 360° VR video rendering.

This tutorial demonstrates how to display 360° video in a native view widget to save the overhead of a whole browser stack. This is done by using the versatile Spectaculum view widget for video rendering and the popular ExoPlayer for video decoding. Both of these libraries are open source under the Apache 2.0 license and available on GitHub and the JCenter repository.
