VideoTexture display issue with some mp4s

[tuarua]

Problem Description

Some mp4s are rendered incorrectly when using VideoTexture. 8pixels at the bottom of the video frame are repeated.

Steps to Reproduce

Minimal example provided here
https://www.dropbox.com/sh/rr9atk0kl51wqfi/AADDAOkz2-xwalpBrEjjCtCua/src?dl=0

The video on the left utilises a VideoTexture and on the right, a traditional flash Video object.
Both are using the same Big Buck Bunny asset from http://bbb3d.renderfarming.net/

Further technical details

"It's very common to code 1080p video in 1920x1088. That's because most
encoders works in macroblock of 16x16."

So coded_height is usually a multiple of 16. VideoTexture doesn't appear to handle video which has a coded_height and height which is different.
So the height of the big Buck Bunny is marked as 1080 but it's coded_height is 1088
The difference is added as 'banding' at the bottom of a video (8px)

Known Workarounds

Re-encode video using FFmpeg or other tool to encode at a height which is a multiple of 16, padding with white/black border as needed.

On which platforms did you test this, i.e. does it make any difference if the code is running on iOS / Android / Desktop, and Flash Player vs. AIR? Thx!
