FFMPEG plugin: Tell the FFMPEG library to handle incomplete data.

Browse Source 
- It is just one flag that needs to be set, so that streaming video data can be
  handled by the FFMPEG library.

- For reference: This flag is based on FFMPEG's 0.10.2 video decode example
  (doc/example/decoding_encoding.c).

- The _DecodeNextVideoFrame() method needs to be adjusted (still to come), to
  take streamed data into account. So the flag on its own doesn't help, but it
  is a reasonable step in that direction.
