Release 3.4.2 of the Amazon Kinesis Video C++ Producer SDK

Version bumps

• kvsCommonLws from 178109a5dbfc5288ba5cf7fab1dc1afd5e2e182b to v1.5.3.

Release 3.4.1 of the Amazon Kinesis Video C++ Producer SDK

Release 3.4.0 of the Amazon Kinesis Video C++ Producer SDK

What’s new:

• Added install to CMake to allow using CPP SDK as a dependency in other projects
• Added support for China (Beijing) region
• kvssink specific improvements:
  • New signal stream-client-metric to get client and stream metrics. Ensure to enable this feature through the get-kvs-metrics property
  • New signal stream-error to get error codes returned while streaming. This gives application more control over reacting to non-recoverable errors
  • New signal fragment-ack to listen in on incoming fragment ACKs. Useful to track if the fragments are getting persisted and relevant application decision making
  • Allow configuring timeout values while stopping streaming through the stop-stream-timeout property
  • Allow backfilling support through the use-original-pts property for offline streaming mode
  • Disable stream creation through SDK if it does not exist through the allow-create-stream property
  • Allow user agent configuration through the the user-agent property
  • Allow setting CURL connection and completion timeouts for service call via connection-timeout and completion-timeout
  • Allow setting CURL connection and completion timeouts for IoT credential provider as part of iot-certificate property. Add connection-timeout and completion-timeout attributes within the iot-certificate property

Sample:

• New gstreamer sample demonstrating use of kvssink : kvssink_gstreamer_sample

Bug fixes

• Fixed user agent string to be SDK and version specific
• Enable API result caching by default
• Allow stopping of gstreamer pipeline in the middle of a run as a method to support event reactions

Version bumps:

• OpenSSL updated from 1.1.1g to 1.1.1t
• Log4cplus update from 1.2.2 to 2.0.1

Release 3.2.0 of the Amazon Kinesis Video C++ Producer SDK

Platforms tested on

Linux
Windows
MacOS

Release tagged at: 00ba9cf

Whats new:

• Expose new property elementaryFrameRate to provide consumers an accurate frame rate measurement.

Bug fixes:

• Fix potential memory leak issues with kvssink GStreamer plugin

Changes in Producer C: 99c1a8cd8cec88f99c9c4ce3944b53ae341d1491

• Added ability to create authentication callbacks based on existing credentials
• Added logic to prevent unnecessary calls to curl_easy_pause to pause connection by blocking thread which waits for new data, with exponential back off, for ~600ms. curl_easy_pause incurs a 1s or more penalty on unpause so we avoid this now which in most cases results in a significant decrease in end-to-end latency.

Changes in PIC Commit: 296adbd889bf7a193dddc65341209863bf397554 (https://github.com/awslabs/amazon-kinesis-video-streams-pic/tree/296adbd889bf7a193dddc65341209863bf397554)

• Added public API kinesisVideoStreamSetNalAdaptationFlags to set NALU adaptation flags prior to starting the stream
• Added elementaryFrameRate to client metrics to provide consumers an accurate frame rate
• Fixed a bug which impacted a scenario where IoT Credentials fail to refresh due to bad network and the state machine would get stuck and unable to self recover.
