How to generate MPEG DASH manifest file using AWS elemental media convert for audio only?

Hi

According to the Alexa Skills developer documentation https://developer.amazon.com/en-US/docs/alexa/custom-skills/use-long-form-audio.html

Your audio file must be in one of the following formats: AAC/MP4, MP3, PLS, M3U/M3U8, HLS. Your audio stream must support bit rates of 16 – 384 KB per second. The Audio component supports audio files in the following formats:

You can create AAC audio only with HLS with MediaConvert https://docs.aws.amazon.com/mediaconvert/latest/ug/setting-up-audio-only.html

You can also create DASH outputs with audio only in AAC format.

For MP3 audio output you will have to use File Group type of output, remove the video output, select No container for the type of container and select the audio codec MPEG-1 Layer III (MP3)
