5.3.13 Media Player

The media player element uses the Windows MCI interface to playback video or sound-files. AVI, WMV, WAV, MP3 and other formats could be used. After a mediafile has been selected, it is played by receiving a value different from

INVALID_Value at its play input port. Volume and playback speed can be adjusted by the Vol and speed ports, if supported by the media format (1000 sets full volume / normal speed). The center position is used to calculate the actually media file position by adding the relative value sent to the position input port. This position data and the update interval for positions are given in milliseconds. Input values sent to the step port cause a video file to step one frame forward (if supported by the media format).
