Rekognition Streaming Video events and Custom Labels

Question

Hi,

i am trying to configure  Rekognition with Streaming Video Events but i am having a hard time when trying to use custom labels. Works fine with Face detection but i want to detect specific "labels" in a live video.

I have created a KVS, configured the SDK and can stream video from my laptop and IP camera.

But, if try to create a Stream processor with custom labels i keep getting an error
`An error occurred (InvalidParameterException) when calling the CreateStreamProcessor operation: Invalid label(s) specified for ConnectedHome: "XXXXX", "YYYYY"`

Is there a limitation in use cases so that Streaming Video Events can only be used with Person, Pet, All labels?

I know that a workaround is to use a kinesis stream, lambda, fetch frames from the video , store them in S3 and Rekognition will do the rest.

But i was hoping that could do the same with live video and Streaming Video Events.

Thanks

Dear Nikitas,

Thanks for reaching out.

CreateStreamProcessor API can be used to create StreamProcessors with two different settings in Amazon Rekognition: detecting faces (FaceSearch option in Settings) and detecting labels (ConnectedHome option in Settings).

Rekognition Streaming Video Events currently only offers label detection on one of the following labels: PERSON, PET, PACKAGE, ALL for ConnectedHome option in Settings.

You can refer to the below documentation for more details:
* CreateStreamProcessor: https://docs.aws.amazon.com/rekognition/latest/APIReference/API_CreateStreamProcessor.html
* Label detection operations for streaming video events: https://docs.aws.amazon.com/rekognition/latest/dg/streaming-labels-detection.html
* Detecting labels in a video: https://docs.aws.amazon.com/rekognition/latest/dg/labels-detecting-labels-video.html
* Detecting custom labels: https://docs.aws.amazon.com/rekognition/latest/dg/labels-detecting-custom-labels.html
