I am testing SRT on Wowza Streaming Engine. The on-prem live encoder is sending srt stream with Dolby Audio in it. The Wowza Encoding Engine does not recognize the audio and gets rid of audio stream and publishes DASH and HLS outputs without audio in it.
If I configure on-prem live encoder with AAC audio, it works and I see audio track as part of DASH and HLS outputs.
