Refactor player sessions Fix PixelStreamingAudioComponent had delayed audio. Fix audio bitrate from Unreal Engine to browser was set to a low default causing compressed audio quality in stream. The new default is now Opus maximum value of 510kb/s. Fix the Selective Forwarding Unit (SFU) not being added to the Pixel Streaming samples folder for a packaged project Fix default max bitrate not being high enough to support 4k. Fix reconnections not autoplaying in the browser. Add datachannel support to SFU. Add WebRTC c++ client behaviour to pixel streaming system. This is used for developing unit tests. Add a unit test that will start streaming, connect a client and check that a data channel message can be sent. Add the ability for a user to start/stop streaming as needed through the use of PixelStreaming.StartStreaming and PixelStreaming.StopStreaming Add the ability for the stream resolution to be changed at runtime Notes: AVEncoder no longer stores a width and height; These properties have been moved to the FVideoEncoderInput. This input is now the source of truth and both AMF and NVENC will adapt their resolution to the input resolution. #rb luke.bermingham #fyi mattias.jansson, nick.pace, matthew.cotton, aidan.possemiers, sandor.hadas #preflight 6204c7aba65a8a28464df03c #jira none [CL 18948482 by William Belcher in ue5-main branch]
