mainloop(devicHandle, frameCount)

Run main capute loop [frameCount] times. Returns 0 on success.

stop_capturing(devicHandle)

Stop capturing on opened device. Returns 0 on success.

uninit_device(devicHandle)

Uninitialize already opened device. Returns 0 on success.

close_device(devicHandle)

Close already opened device. Returns 0 on success.

copy_buffer_bytes(numBytes)

Copy [numBytes] from buffer to new buffer [Array{UInt8,1}]

copy_buffer_bytes!(outbuffer, numBytes)

Copy [numBytes] from buffer to existing buffer outbuffer[Array{UInt8,1}]
