Upon reading that the Logitech C920 webcam has a hardware H.264 encoder I ordered one with visions of streaming direct from the camera or saving the H.264 stream straight to disk. After receiving it, looking at the settings and reading more about it online, the H.264 function apparently intended to get 1080p video accross the bus at USB 2.0 speeds, and the Windows drivers so far don’t seem to offer a simple way to directly stream or save the H.264 content from the camera’s encoder.

So that’s somewhat disappointing. It also apparently won’t operate at USB 3.0 speeds.
