@vediyappan-hcl , what are you wanting to do with the streamed video data
in app-service-configurable?
Note: Normal edge use cases feed the stream into some AI/ML model at the edge. This inference results from the model (typical JSON) are then sent into EdgeX (typically using Device MQTT or Device REST). Then a custom app service can do analysis on the inference data to make decisions.
The following Intel reference implementations demonstrate this approach: https://intel-iot-devkit.github.io/rtsf-at-checkout-reference-design/ https://intel-iot-devkit.github.io/automated-checkout/index.html
@lenny-intel Yes, I aware this video inferencing use case.
I want to store the streamed video data inside EdgeX or outside EdgeX. For that I want to see the video frames in MessageBus or app-service-configurable.
Able to store the video stream outside EdgeX with following command:
ffmpeg -i rtsp://localhost:8554/stream/VirtualBox_Webcam_-_HD_User_Fac-9464eb7e2d647de4 -vcodec copy -acodec copy -map 0 -f segment -segment_time 300 -segment_format mp4 "ffmpeg_capture-%03d.mp4"
Inside EdgeX, 1. How can I push the video stream to MessageBus? or 2. How can I see the streamed data in app-service-configurable?
@vediyappan-hcl , what are you expecting to do with the video frames in app-service-configurable?
@lenny-intel Before passing the streamed video data to the custom application, I just want to visualize actual data in MessageBus or app-service-configurable to make the changes in custom application and receive it correctly.
@vediyappan-hcl, The camera device services (USB & ONVIF) are not designed to send the video stream through EdgeX. They are designed to control camera devices from EdgeX.
I you want to push the stream thru EdgeX (not recommended) you will need to create a service that gets the stream URL from the device service, converts the stream to frames and then pushes those frames into EdgeX via Device MQTT or Device REST.
@vediyappan-hcl, does this answer your question?
@lenny-intel Yes, it answered my question. Thank you!
I interfaced a webcam with device-usb-camera microservice and able to see the real-time streaming.
StreamURI: rtsp://localhost:8554/stream/VirtualBoxWebcam-_HD_User_Fac-
I need to export streamed video data to a custom application as it is not possible to store binary data in core-data. Before that, I want ensure that the streamed data reaches app-service-configurable. How can I see streamed video data (events/readings) in app-service-configurable?
