Green bar at the bottom of certain videos

Some videos show a green bar at the bottom.

The problem is that VLC sometimes allocates buffers that are larger than the display dimensions of the video. Buffer dimensions and display dimensions are separate concepts. The media framework API does not currently support this, and it expects both to be the same.

I'm going to address this as part of the timecode related refactor for 4.15. Since we cannot clamp the sampling of the buffer (render device specific), I think we need to clamp the buffer in a shader instead, similar to what we're doing in PS4Media.

This will be fixed in the UE4 Master branch on Wednesday 10/26

This is fixed starting with ce06caf

(requires 4.15 code, which isn't on Github yet - will be merged up November 23rd)
