Seems there is a severe regression with video playback in Android 5.0 that is affecting at least the Nexus 10 and Nexus 7.2 (seems to be all devices running 5.0). It is yet unresolved....
"I noticed that most of YouTube videos display the " There was a problem while playing the video. Touch to retry" message. I have tried opening YouTube in Chrome but I got the same message.
I also tried playing some other videos that I copied on the device or from my Drive account. They don't work as well Also the camera doesn't record video. I touch the record button but nothing happens."
