Deinterlace not working in Clang Build

[CharlesMengCA]

We may need to stay on gcc build for a while.

I don't see noticeable performance gain using Clang build.

Should be fixed by #426

We may need to stay on gcc build for a while.

It hasn't even been that long since clang support was merged! Give it a little window to stabilize.

All known issues should have been resolved by now. Please feel free to report any clang build problems.
