in property group and I have

Unknown or legacy key specified ‘raw-output-generated-callback’ for group [property]

Are they deprecated?

Deepstream 5.0

There is no update from you for a period, assuming this is not an issue any more.
Hence we are closing this topic. If need further support, please open a new one.
Thanks

Are you using gst-launch-1.0 to run the pipeline?
