Qt-based media player
This patch implements a simple Qt-based media player which is actually a graphical user interface for the SDL-based 'avplay' media player from 'libav'. It starts 'avplay' as a child and shows its graphical output in a 'QNitpickerViewWidget'. The widgets for controlling the player state send the according keyboard and mouse input events to 'avplay'. The 'qt_avplay' player supports the following configuration options: <mediafile name="..."/> -> name of the media file to play <framebuffer_filter name="..." ram_quota="..."/> (may appear multiple times) -> name of a framebuffer filter service to filter the video output Fixes #222.

name of the media file to play

|

This node contains the name of a framebuffer filter service to filter the
|

video output. It may appear multiple times. If specified more than once, it
|
||||
is possible to build a post-processing pipeline for the video display where
|
||||
each processing stage is executed by a separate program.
