Added remote application install and bug fixes

• Implementation of adding an application remotely from ChrysCloud
• Improved device status change reporting (e.g. Camera offline) for Slack and Webhook notifications

Bug fixes and integration with ChrysCloud

• Changed the LatestVideoImage interface to Unary gRPC call
• Improved response times of LatestVideoImage to be ale to analyze even more connected cameras
• Added In memory buffer probe (start, end and length of the in memory buffer)
• MQTT integration for camera installation and removal from Chrysalis Cloud
• Reporting monitoring to Chrysalis Cloud (memory, cpu, camera online, offline, ...)
• Bug fixes

In-memory buffer, video probe, corresponding examples and object detection example

Implementation of in-memory buffer

Added gRPC methods to access in-memory buffer:
rpc VideoBufferedImage(VideoFrameBufferedRequest) returns (stream VideoFrame) {}

In memory buffer stores compressed video, packet by packet. It can be queried between two timestamps (from, to). To query the complete in memory buffer define: timestamp_from = 0 and timestamp_to = sys.maxsize

Added gRPC to return basic information about a video stream:
rpc VideoProbe(VideoProbeRequest) returns (VideoProbeResponse) {}

Returns VideoCodec object:

message VideoCodec {
    string name = 1;
    int32 width = 2;
    int32 height = 3;
    string pix_fmt = 4;
    bytes extradata = 5;
    int32 extradata_size = 6;
    string long_name = 7;
}

Added gRPC method to return system time:
rpc SystemTime(SystemTimeRequest) returns (SystemTimeResponse) {}

Returns current system time in the Chrysalis Edge Proxy.

Examples on how to use in-memory buffer

• opencv_inmemory_display.py (single process consumer)
• opencv_inmemory_display_advanced.py (multiple process consumer)
• yolo_object_detection.py example how to do object detection in live video stream from RTSP camera

BugFix mp4 segment creation

Mainly fixing mp4 file segmenting.

v0.0.5

• Web UI/UX bug fixes (error reporting on creation of new RTSP stream)
• Manual upgrade of existing edgeproxy containers when new version available
• Other minor bug fixes

Bug fixes and on disk circular buffer upgrade

• Few minor bug fixes
• moved circular buffer management to individual running container, separating concerns to specific camera process instead of global management

v0.0.3

• store key-frame segmented mp4 files to local disk
• running mp4 segment cleanup cron job

v0.0.2

• Added settings to store Chrysalis Edge Key/Secret
• Added gRPC service to turn storage on/off on Chrysalis Cloud
• Removed ProxyStart/ProxyStop methods and created a single method Proxy with on/off functionality
• Added Streaming API connector for Computer Vision Annotations

v0.0.1-alpha

Initial alpha release. More testing required.
