This image has two video tracks in the MP4 data, one is a 'real' video
which we want to play by default, and the other is a low-fps video track
which isn't intended to be directly played, it's encoded in HEVC for
compression and decoding efficiency.
This test demonstrates ExoPlayer's current behaviour default extraction
and playback, which results in selecting the high-res, low-fps track
(actually single sample in this example), instead of playing the actual
video.
