Summary

Memory size reduction

• This release focuses primarily on memory footprint improvements and additional configurability.

Key highlights include:

• Reduced memory usage through optimized data structures and heap allocation.
• Added a new optional API for applications to configure the outbound transceiver's rolling buffer size.
• Made ICE stats calculations optional for improved performance.

What's New

• Added a new optional API configureTransceiverRollingBuffer to reduce the size of each transciever's RTP packet store from the default. (#2077)
  • Updated the kvsWebrtcMaster.c sample application's rolling buffer configuration using the new configureTransceiverRollingBuffer API to fit the bitrate required by the included sample frames. (#2089)

[!TIP] For additional configureTransceiverRollingBuffer details, refer to Controlling RTP rolling buffer capacity in the ReadMe.

SDK Changes

• Implemented new API configureTransceiverRollingBuffer. (#2077)
• Moved the TWCC packet store and TWCC packets from the stack to the heap and reduced the store size. (#2075)
• Changed the underlying TWCC packet store implementation from an array to a hashTable. (#2075)

Summary

[!IMPORTANT] With this release, the previously reported issue (#2038) concerning TURN connections has not been observed.

Time to First Frame (TTFF) Improvements

• This release has been tested for TTFF across a diverse range of platforms, including System-on-Chips (SoCs), operating systems, and network topologies (STUN/TURN). Our SDK sample applications, including camera, web browsers, and mobile viewers, were used for these tests. We observed an average improvement of 15-30% in TTFF without impacting other performance indicators, such as connection success rate.

[!NOTE] The performance metrics provided are based on testing in controlled environments. It is important to note that the actual performance, specifically the time between sending the offer and rendering the first frame, may vary based on factors such as bandwidth availability, latency, packet loss, and the crypto libraries used (MbedTLS or OpenSSL).

Added Support for H.265 Codec

• More details on running the SDK with H.265 can be found in the README.

What's New

https://github.com/awslabs/amazon-kinesis-video-streams-webrtc-sdk-c - Release 1.10.0 of the Amazon Kinesis Video WebRTC C SDK

What’s new:

• Improved time-to-first-frame latency with new CMAKE flag ENABLEKVSTHREADPOOL. This flag is Enabled by default. KVSUSESIGNALINGCHANNELTHREADPOOL has been deprecated now. (https://github.com/awslabs/amazon-kinesis-video-streams-webrtc-sdk-c/pull/1806)
• Added feature to send master time-to-first-frame for JS viewer timeline visualization; enable with enableSendingMetricsToViewerViaDc (https://github.com/awslabs/amazon-kinesis-video-streams-webrtc-sdk-c/pull/1846)
• Optimized time taken to gather TURN servers using GetIceServerConfig by supporting an async call pattern. In case of srflx based peer connection, this is a latency improvement since the SDK does not unnecessarily wait on getting TURN server URLs during signaling setup. ENABLEKVSTHREADPOOL required (https://github.com/awslabs/amazon-kinesis-video-streams-webrtc-sdk-c/pull/1854). Sample change required to gather relay candidates
• Changed default build type from Debug to Release; use -CMAKEBUILDTYPE=Debug for debug mode. (https://github.com/awslabs/amazon-kinesis-video-streams-webrtc-sdk-c/pull/1897)

Sample bug fixes:

• Sending key frames before other frames in Samples. Frames are now sent only after SRTP is READY (https://github.com/awslabs/amazon-kinesis-video-streams-webrtc-sdk-c/pull/1833)
• Added checks for empty/null session token (https://github.com/awslabs/amazon-kinesis-video-streams-webrtc-sdk-c/pull/1874)

Bug fixes / Improvements:

• Fixed trickle ICE to be a session level and media level attribute instead of it being only a media level attribute (https://github.com/awslabs/amazon-kinesis-video-streams-webrtc-sdk-c/pull/1813)
• Optimized time taken for STUN DNS resolution to have STUN server address ready for srflx candidate gathering - ENABLEKVSTHREADPOOL required (https://github.com/awslabs/amazon-kinesis-video-streams-webrtc-sdk-c/pull/1812)
• Improved DTLS handshake time by moving to a state transition based approach to be more responsive to the incoming DTLS handshake messages - ENABLEKVSTHREADPOOL required (https://github.com/awslabs/amazon-kinesis-video-streams-webrtc-sdk-c/pull/1824)
• Optimized ICE and TURN state machine state transitions. They allow early state transitions if possible, instead of waiting for next timer iteration (https://github.com/awslabs/amazon-kinesis-video-streams-webrtc-sdk-c/pull/1825)

Release tagged at : 2dff44fea83a79336fda676ba2801d0d77417cd1

Bug Fixes:

• Fixed an issue where connected sockets were not sending pings

Details about Bug:

Between v3.x.x and v4.x.x the LWS changed the struct that managed the retry policy. In LWS v4.2.0-.2 there is a bug in the create LWS context function. It checks only if ping is passed in, and then assigns both ping and hangup passed in values. Hangup can be undefined in this case

``` 1045 context->defaultretry.secssincevalidping = 300; //defaults 1046 context->defaultretry.secssincevalidhangup = 310; 1047
1048 if (info->retryandidlepolicy && 1049 info->retryandidlepolicy->secssincevalidping) { //check for ping value to be non-zero. 1050 context->defaultretry.secssincevalidping = 1051 info->retryandidlepolicy->secssincevalidping; 1052 context->defaultretry.secssincevalidhangup = 1053 info->retryandidlepolicy->secssincevalid_hangup; //this is the passed in value of hangup, which could have been unassigned 1054 }

``` We need to pass in a hangup value greater than the ping value, or the pings will not occur.

Whats’s new: - Support on Windows - Fixed broken data channel message receive - Added capability to handle more transceivers - Allowing ICE username/password unto 256 bytes - Added PRtcDataChannel to data channel callback arguments - Added new data type to allow certain nullable types specified in RTC spec - Provision to support trickle ICE based on Remote description - File logging in samples - PIC is built through producer C - NAT behavior detection facility (cb00f8e) - Added restartIce api.

Producer C Changes: (270c0b6612cc553d458e316e835471c693f518bd) - Build system enhancement - navigation away from use of submodules - Using only JSMN header - Added file logging in samples - New status codes for file credential provider

Improvements: - Unit tested data channel send message after DTLS handshake - Fix leak when ice restart fails

Known Issues: * Incorrect transceiver direction breaks SDP exchange in Firefox and iOS * Partial reliability does not work as expected. Need to add library level tests to validate * Reduce memory allocations in sending audio/video packets
