Release 1.8.0 of the Amazon Kinesis Video WebRTC C SDK

[disa6302]

What’s new:

• New latency measurement metrics available to read the time taken by different steps in the WebRTC peer set up process - PeerConnectionMetrics and KvsIceAgentMetrics
• Provision to use threadpool for thread management in signaling client to handle signaling messages. Control the size of the threadpool using SignalingClientInfo structure and enable usage by defining KVS_USE_SIGNALING_CHANNEL_THREADPOOL . Instructions are added to the README.md
• Provision to profile code section using PROFILE_* macros
• Added support for China (Beijing) region

Sample:

• Fixed potential memory leak in sample tear down
• Recreate signaling client if signaling client creation fails
• Changed GOP size of sample video from 10s to 2s
• Added RTSP source to gstreamer sample app
• Multiple bug fixes in samples

Bug fixes / Improvements:

• Fixed SDK build issues with libwebsockets on Windows
• Fixed poll() call failure on Windows
• Overwrite final entry in signaling cache if cache file reaches maximum entries
• Answer’s m line is generated based on the offer’s m line in SDP to avoid m line mismatch error when running with web browsers as the peer
• Build SCTP library only when ENABLE_DATA_CHANNEL flag is set
• Added jitter buffer overflow check to prevent frames from getting dropped due to timestamp integer overflow
• Improved latency in TURN state transitions by about 2 seconds
• Fixed user agent string to be SDK and version specific
• Fixed crash from race condition in ConnectionListener teardown
• Improved latency in resolving TURN server URLs by directly parsing the IP from the getIceServerConfig response
• Logging improvements

Version bumps:

• OpenSSL updated from 1.1.1g to 1.1.1t
