ISL AlwaysOn - Desktop - Prioritize chan channels -2 and -1 (DEFECT) [ISLALWAYSON-1913] More


User experienced an issue with reduced desktop sharing performance when connected to an ISL AlwaysOn machine and having the option to stream in best quality. The issue was that the streaming side chose to stream in best quality instead of using the quality optimized codec. 

When direct connection functionality was introduced this issue also became apparent. There are two special channels -1 and -2 which are used for program initialization, status and reliability messages. The special channels should have priority when sent over the network, however due to an issue they were not prioritized. 

When desktop streaming is initialized it sends it's init messages to remove side on channel -1 and when remote side recevied init messages it starts desktop streaming on desktop channel. This caused an issue because desktop stream was sent to other side before all desktop init messages were received, causing to start streaming with incorrectly selected codec.

The defect was fixed.
