Snap from my current code.
Simply trying to stream using MJPEG(OAK-1-PoE)

def create_pipeline():
# Start defining a pipeline
pipeline = dai.Pipeline()
# Define a source - color camera
colorCam = pipeline.create(dai.node.ColorCamera)
colorCam.setPreviewSize(300, 300)
colorCam.setResolution(dai.ColorCameraProperties.SensorResolution.THE_1080_P)
colorCam.setInterleaved(False)
colorCam.setColorOrder(dai.ColorCameraProperties.ColorOrder.BGR)
return pipeline
# Save the pipeline as a .dap file
pipeline = create_pipeline() # Change 'depth' based on your requirements
dai.DeviceBootloader.saveDepthaiApplicationPackage(
'./OAK1_MJPEG_Streaming.dap', # Where to save the .dap file
pipeline, # The pipeline you just created
compress=True, # Compress the file
applicationName='OAK1Streaming' # Optional application name
)
I have Couple of question.
First I am receiving the following error when i try to flash the .dap file
Secondly, do I need to change localhost with anything else.
# start TCP data server
server_TCP = socketserver.TCPServer(('localhost', 8070), TCPServerRequest)
th = threading.Thread(target=server_TCP.serve_forever)
th.daemon = True
th.start()
# start MJPEG HTTP Server
server_HTTP = ThreadedHTTPServer(('localhost', HTTP_SERVER_PORT), VideoStreamHandler)
th2 = threading.Thread(target=server_HTTP.serve_forever)
th2.daemon = True
th2.start()
