Logitech C920 USB Camera works for H.264 Frame Based out-of-the-box with the 
H.264 format patch applied toV4l2 base on usb.org "USB Device Class Definition 
for Video Devices: H.264Payload".  It  would be nice to get the encoder XUs with 
associated controls working. 


>From the document:

The control and payload specifications are described in this document. This
includes: 
- Stream Based H.264 Payload Format

Sure.
you can edid
/usr/share/uvcdynctrl/data/046d/logitech.xml
and assign XUs to proper V4L controls.
