Humble video decodes video with wrong timestamps using DecodeAndPlay demo (video attached)

[Rubydesic]

I just tried to play this video on the 'DecodeAndPlay' demo, and it gets played at 0.47 fps, the timestamps are all messed up on each frame. If I want it to play at around 60fps I have to divide every timestamp by 128: var streamTimestamp = picture.timeStamp / 128 in the first line of displayVideoAtCorrectTime.

How should I go about correctly decoding this video's timestamps?
