Add multi-audio support for Smooth live stream multi-bitrate ingest from client encoders
Currently multiple audio streams (multi language) for live encoding ingest only work for RTP single bitrate video streams. Please add support for multiple language tracks to live multi-bitrate Smooth streams pushed from a client encoder. Scenario: Elemental Live encoder creates multi-language multi-video bitrate Smooth stream that gets pushed to AMS live channel over public internet connection. This is needed, because the RTP (UDP) protocol is not reliable for pushing over public internet connections, and the Azure Media Encoder encoding profiles do not always meet the specific scenarios or encoding options an on premise live encoder can offer.
