@seanbuff - as good as it sounds, and as ludicrous it may be to tell a satisfied customer that his satisfaction might be erroneous - I'm afraid, I still have to.
The reason is, that we haven't implemented hw color mapping/conversion for QuickSync yet.
There's one thing that might be happening in your case:
Our latest ffmpeg allows separate hw contexts for QuickSync encoder and decoder. So you might see QuickSync decoding _and_ QuickSync encoding - but what's happening in-between is done in software. So, the 10bit color conversion is probably done in software while decoding and encoding is done in hardware.
If I could see a log file, I could confirm..
