When converting to RGB48LE, FFMPEG expands limited Y values into full ones. At least, according to this hex editor I'm looking at. I see Y vales of 64 (little-endian) for the raw YUV420P10LE stream. But when I convert to RGB48LE, they become 0. Converting back to YUV420P10LE from RGB48LE brings it back to limited range.

Where's that bottle of sake... I need to drink... I'll try to wrap my head around this in the morning. Or maybe use it to drive nails into the siding of my house.
