Bug-behavior: Youtube-videos using VP9 and opus as audio-codec started loading but did not play
Reason: While parsing the audio-stream, the sampling frequency (short rate) was wrongly parsed by
        nestegg, returning 0 all the time. This led to the audio-track reporting that it neither had 
        valid video nor audio. Which led to an endless-loop in the video state machine.
Solution: Correct parsing of rate in nestegg, which is a float and cuts of bytes.
