Guilty of copy and pasting.

PlayVideo? Why .mov instead of .wav files? Also I'm thinking we should enable
the be variants for all of chromium, not just ChromeOS.

FFmpeg refuses to encode into big endian wav files. I could not find any samples
online. Remember we encountered them inside of the skydiving video. But we
should check with rbultje.
The skydiving video was a video that did not play on Chrome but on CrOS. (The
link is dead unfortunately.) If there is a way to encounter this variant in
Chrome I agree we should enable it there.
