Release 1.7.1 of the Amazon Kinesis Video WebRTC C SDK

Release tagged at: 111c253

Bug Fixes:

Increased SDP attributes limit to 256 from 128 to accommodate larger SDP sizes from Chrome v98: #1389. Note that the SessionDescription now increases in size by about 390k bytes (SdpMediaDescription and SessionDescription allows 256 attributes each, and each attribute is 512 bytes).

Producer C version:

v1.2.X (unreleased at this time) - c7fce9e06021452ff3c42dc70c8360606b22ad53

Release 1.7.0 of the Amazon Kinesis Video WebRTC C SDK

Release tagged at: 22c9e3d

Whats new:

Updated libwebsockets library to 4.2.2
make clean command added
Full jitter (range of jitter equal to base wait time) on exponential backoff of repeated signaling API calls
Full jitter & exponental backoff on non-200 results at the state machine level
Clock skew adaptations
System time is compared to server time (with timezone corrections). If a skew is detected, the delta will be saved and the API retried.
Skew per API service is tracked.
Better caching of IoT credentials. Resetting of the state machine for non-auth reasons will no longer require re-creating the signaling client.

Sample improvements:

Showcase data channel support in WebRTC Viewer sample.
Sample no longer destroys and recreates signaling client to reset state machine.

Bug Fixes

issues resolved: #1174 #1225 #1249
FD leak patched in LWS #1263
fix pare_status.py script #1268
Resolve LWS interface layer not appropriately reporting failures in some cases #1328
DCEP protocol issue fixed for non-null values #1228
