1 – Release Notes

The main new feature of GeeXLab 0.29.1 for TinkerBoard is the support of the FFmpeg plugin. In previous versions of GeeXLab for TinkerBoard, this plugin was not available because I didn’t know how to play sounds on the TinkerBoard. I thought it was like on RPi, via the OpenIL / OMX interface, but IL/OMX is not supported on TinkerOS. And two days ago, I decided to check the ALSA support and I discovered that I could compile SDL2 + ALSA support on TinkerBoard. Great! With ALSA support, the compilation of the FFmpeg plugin using SDL2 for audio playback was easy (even if it takes years to compile FFmpeg on the TinkerBoard 😉 ). So now, we can play videos (like .mp4) with GeeXLab on the TinkerBoard.

A demo of a very simple video player is available in:
{GeeXLab folder}/demos/audio_video/video_player_gl2es.xml

GeeXLab for TinkerOS comes with the OpenGL ES 2.0 / 3.2 support only. I stopped the OpenGL 3.0 support because it’s a software implementation, there’s no GPU-accelerated OpenGL 3.0 on the TinkerBoard. OpenGL ES 2/3 is GPU accelerated which is enough even if it adds some work to code demos for regular OpenGL and for OpenGL ES (fortunately, the changes are only in shaders).

The following shadertoy demo of is available in:

GeeXLab for TinkerBoard has been compiled on a TinkerBoard + TinkerOS 2.0.11 (Linux 4.4.132+ / Debian 9.11 Stretch) with gcc/g++ 6.3.0 (GeeXLab app and all core libraries and plugins).
