During stream off, send HFI_CMD_STOP to firmware which is a synchronous command. After the response is received from firmware, the session is closed on firmware. Introduce different states for instance and state transitions. IRIS_INST_INIT - video instance is opened. IRIS_INST_INPUT_STREAMING - stream on is completed on output plane. IRIS_INST_OUTPUT_STREAMING - stream on is completed on capture plane. IRIS_INST_STREAMING - stream on is completed on both output and capture planes. IRIS_INST_DEINIT - video instance is closed. IRIS_INST_ERROR - error state. | v ------------- +---------| INIT |--------- + | ------------- | | ^ ^ | | / \ | | / \ | | v v | | ----------- ----------- | | | INPUT OUTPUT | | |---| STREAMING STREAMING |---| | ----------- ----------- | | ^ ^ | | \ / | | \ / | | v v | | ------------- | |--------| STREAMING |-----------| | ------------- | | | | | | | | v | | ----------- | +-------->| DEINIT |<----------+ | ----------- | | | | | | | | v | | ---------- | +-------->| ERROR |<-----------+ ----------.
