44 * Interface for accessing a video camera device on the client.
45 *
46 * Async callbacks are used for providing feedback, reporting errors, etc.
47 *
48 * Initial version supports: Camera + Processing Unit + Streaming Control.
49 *
50 * There are 2 modes:
51 * 1) The virtual WebCam is already attached to the guest.
52 * 2) The virtual WebCam will be attached when the client has it.
53 *
54 * Initially the mode 1 is supported.
55 *
56 * Mode 1 details:
57 * The WebCam has some fixed functionality, according to the descriptors,
58 * which has been already read by the guest. So some of functions will
59 * not work if the client does not support them.
60 *
61 * Mode 2 details:
62 * Virtual WebCam descriptors are built from the client capabilities.
63 *
64 * Similarly to the smartcard, the server will inform the ConsoleVRDE that there is a WebCam.
65 * ConsoleVRDE creates a VRDEVIDEOIN handle and forwards virtual WebCam requests to it.
66 *
67 * Interface with VBox.

142 *
143 * Notes:
144 * * still capture uses a method similar to method 2, because the still frame will
145 * be send instead of video over the channel.
146 * Also the method 2 can be in principle emulated by both 1 and 3 on the client.
147 * However the client can initiate a still frame transfer, similar to hardware button trigger.
148 * * all control changes are async.
149 * * probe/commit are not used. The server can select a supported format/frame from the list.
150 * * no color matching. sRGB is the default.
151 * * most of constants are the same as in USB Video Class spec, but they are not the same and
152 * should be always converted.
