Playing MP4 and FLV with QMediaPlayer

[JasonKretzer]

The ability to play format X on Windows requires a Windows codec for format X installed the machine. Default codecs vary from Windows version to version and between Home, Pro, and Ultimate editions etc. Chances are that if Microsoft's media player cannot play the file then Qt will not be able to either.

The FLV container may contain video encoded with Sorenson Spark, VP6, or H.264 codecs, and audio in either the Shockwave Flash format or AAC.

Thats just it, the mp4 plays in windows media player. I have installed the K-lite codec pack as well. All to no avail, still getting the black box
