This release is an update to the Video Analyzer edge module and the Video Analyzer service. The release tag for the edge module is:
mcr.microsoft.com/media/video-analyzer:1.1.0
Note
In the quickstarts and tutorials, the deployment manifests use a tag of 1 (video-analyzer:1). So simply redeploying such manifests should update the module on your edge devices when newer tags are released.
The ARM API version of the Video Analyzer service is:
2021-11-01-preview
New functionalities
- When using Video Analyzer with Computer Vision for spatial analysis AI service from Cognitive Services, you can generate and view new insights such as the speed, orientation, trail of persons in the live video.
- You can discover ONVIF-capable devices in the local subnet of your edge device.
- You can capture and record live video directly in the cloud.
- You can use low latency streaming to view the live video from the RTSP camera with end-to-end latencies of around 2 seconds.
- You can implement the Video Analyzer IoT PnP contract on your RTSP camera to enable video capture from your device to the Video Analyzer service.
- You can export the desired portion of your recorded video to an MP4 file.
- You can specify a retention policy for any of your recorded videos, where the service would periodically trim content older than the specified number of days.
- Videos recorded using Video Analyzer edge module can include preview images or thumbnails periodically, enabling a better browsing experience.
Known issues
- When using low latency streaming, only one client can be connected to the service at a time
- When using a gRPC extension module for inferencing with shared memory, both the Video Analyzer edge module and the extension module should run in the same user and group
