Can not create a video stream

[dgsngular]

Hello everyone,

We are testing a Vertex AI vision for streaming video processes and we have a problem when trying to create streams:

vaictl -p PROJECT_ID \
         -l LOCATION_ID \
         -c application-cluster-0 \
         --service-endpoint visionai.googleapis.com \
send rtsp to streams STREAM_ID --rtsp-uri RTSP_ADDRESS

The logs that it returns are as follows:

They have been doing research and have found that there is an open question that could be related to gRPC:

https://github.com/grpc/grpc/issues/29706

I've checked de gRPC version on Vertex AI Vision library:

go_repository(

        name = "org_golang_google_grpc",

        importpath = "[google.golang.org/grpc](http://google.golang.org/grpc)",

        sum = "h1:u+MLGgVf7vRdjEYZ8wDFhAVNmhkbJ5hmrA1LMWK1CAQ=",

        version = "v1.46.2",

    )

Who can help me?

Thanks in advance. Regards,

Hey @dgsngular - we know the problem here and are working on it. @yxue will follow up.

[dgsngular]

Thank you for your reply, @dchao34. We'll be following the new releases and this issue closely, as we're very interested in some Computer Vision projects we're working on.
