Release 1.6.0 of the Amazon Kinesis Video C Producer SDK

What's New

• Dual-stack endpoints support and IP filter options
• Bug fixes and improvements to automated testing

Note

Dual-stack endpoints are not currently supported yet by Kinesis Video Streams.

Bug fixes/improvements

• MacOS: Fixed an issue where the Homebrew OpenSSL was used for Curl instead of the locally-built one. (#478)
• Added a new constructor with client endpoint override parameter. (#480)

Samples

• Adjusted the putFrame loop to add the fragment metadata correctly. (#475)
• Fixed a non-null-terminated string issue in the sample frames file path. (#473)
• Demonstrated using the client endpoint override parameter via environment variable (CONTROL_PLANE_URI). (#480)

Developer Enhancements

• Adjusted the clang-format action to upload the properly formatted files, and a patch file. (#469)
• Added 16 new CI combinations: run the 4 samples on Mac, Windows, Ubuntu (22.04 and 20.04) platforms. (#473)
• Automatically run valgrind on the samples as well on every pull request. (#484)
• Added a new script to perform fragment metadata verification, which runs on every pull request. (#475)
• Added a check that the putMedia connection rotation correctly appends the fragment metadata. (#475)

Note

The development branch containing commits between this release (v1.6.0) and v1.5.4 has been archived into the release-1.6.0 branch.

Release 1.5.1 of the Amazon Kinesis Video C Producer SDK

Bug fixes:

• Fixed timestamp precision in log lines to appropriately represent 3-digit places in millisecond portion
• Added failure check in case the expiration field in file credential provider does not satisfy the format requirement

Release 1.5.0 of the Amazon Kinesis Video C Producer SDK

What’s new:

• Provision to disable creating stream if previously created or to disallow stream creation using the SDK with the StreamInfo.StreamCaps.allowStreamCreation
• New API to create default callback provider for IoT with CURL connection and completion timeouts: createCurlIotCredentialProviderWithTimeAndTimeout , createDefaultCallbacksProviderWithIotCertificateAndTimeouts and createIotAuthCallbacksWithTimeouts
• Added support for China (Beijing) region
• New API to set up log filtering with File logging callback provider: addFileLoggerWithFilteringPlatformCallbacksProvider

Sample:

• New sample to demonstrate offline streaming mode
• Existing video only sample modified to allow codec setting to H.264 or H.265 through command line

Bug fixes:

• Logging improvements
• Added checks for empty credentials to ensure we do not start the state machine unless valid credentials are set
• Fixed user agent string to be SDK and version specific

Version bumps:

• OpenSSL updated from 1.1.1g to 1.1.1t

Release 1.2.0 of the Amazon Kinesis Video C Producer SDK

Platforms tested on:

• Linux
• MacOS
• Windows
• x64
• ARMv5

Release tagged at: 99c1a8c

What’s new:

• 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.

What's new in PIC ref: 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.

Known Issues:

• We call curl_easy_pause from a non curl thread which is not defined behavior. Alternative is to use a curl provided callback but this incurs an unacceptable amount of latency. The solution is to move to the curl MULTI interface.
