pyglet segfaults when playing mp4 movie

[Richard Davis]

The mp4 file can be found here: https://github.com/psychopy/psychopy/blob/master/psychopy/tests/data/testMovie.mp4.

Here's the python snippet which causes the seg fault:

import pyglet
mov = pyglet.media.load('testMovie.mp4', streaming=True)
mov.play()

Which results in:
