Subject: Bug 918 (2/2): Determine StreamWorker usage after stream-init ; Fix
 seek(..) ; Fallback for EOS Detection ; MovieSimple uses full GLEventListener
 for 'Audio Only' as well to test seek

Determine StreamWorker usage after init
  - To support audio only files, we need to determine to use StreamWorker
	after completion of stream-init.

Fix seek(..)
  - FFMPeg: pos0 needs to use aPTS for audio-only
  - Clip target time [0..duration[

Fallback for EOS Detection
  In case the backend does not report proper EOS:

  - Utilize 'nullFramesCount >= MAX' -> EOS,
    where MAX is number of frames for 3s play duraction
    and where 'nullFramesCount' is increased if no valid packet is available
    and no decoded-video or -audio in the queue.

  - Utilize pts > duration -> EOS

MovieSimple uses full GLEventListener for 'Audio Only' as well to test seek
  - Matroska seek for audio-only leads to EOS ..

  - MP4 audio-only seek works

MovieSimple/MovieCube:
  - Use audio-pts in audio-only to calc target time

Tested:
  - A, V and A+V
  - Pause, Stop and Seek
  - GNU/Linux
