Some docker hub base images do not support audio detection

[whbruce]

GStreamer framework base images are expected to include the
audio detection inference plugin libgstaudioanalytics.so. If this plugin is missing the audio detection pipeline will not load, see error message below, and the Video Analytics Serving service will not start.

{"levelname": "ERROR", "asctime": "2020-08-26 01:49:40,114", "message": "Failed to Load Pipeline from: /home/video-analytics-serving/pipelines/audio_detection/1/pipeline.json", "module": "pipeline_manager"}

Currently this plugin is only present in the DL Streamer audio preview so will be not be in any base images obtained from dockerhub.
Thus GStreamer images based on Open Visual Cloud or OpenVINO^™ will exhibit this problem.

As a workaround you can configure the service to ignore initialization errors when you start it.

docker/run.sh -v /tmp:/tmp -e IGNORE_INIT_ERRORS=True

OpenVINO 2021.1 runtime container supports audio. However Open Visual Cloud 20.7 releases do not.

Closing - all supported base images in v0.4.0-beta include audio support.
