Start raw preview allows viewing the raw preview while streaming. It can be used with

S2226_StartRecord or S2226_StartCallback. It should not be used with the S2226_StartPreview

functions.

Use S2226_StopRawPreview to stop the independent preview stream. All streams must be stopped

before the input can be changed.

If the input was changed and S2226_StartRawPreview is still running, then the other S2226_Start

functions will fail until S2226_StopRawPreview is called.

0 on success, negative value if error (see mid2226types.h for error codes list).
