Movie crashes

[alejandro-isaza]

Movie crashes when the device is connected to an external display.

Tested on an external monitor, connected via HDMI.
The c4-presentation (i.e. cocoaconf) app doesn't crash when switching to video.

I downloaded the crash logs from CocoaConf, they don't say much either: https://files.slack.com/files-pri/T03F11137-F1E3CCMT9/download/logs.zip

I did NOT test against an external projector, which may have something to do with the crash... audio? In 3/4 logs there is a reference on various threads (in diff logs) to MediaToolbox.
