The imports should be put in alphabetical order.

Done.

Why do we have to send width and height separately from the File?

[mandermo, 2016/09/16 12:32:30]

Video container .yuv does not contain width and height

[magjed_webrtc, 2016/09/16 13:46:25]

Ok, then I prefer if we use a container that contains width and height, even if
you have to convert from I420 to NV12 at runtime.

[mandermo, 2016/09/23 15:12:03]

Change to .y4m with width and height and conversion from I420 to NV21 at
runtime.
