I’m restreaming an Icecast stream and the initial setup works fine. I installed the transcoder to output audio only 256, 128 and 64 bit streams. I’ve created a new transcoder template called WDETAAC, set to audio only (video disabled), match incoming stream name to template name and fallback template to the WDETAAC template. Under the WDETAAC encoder, I’ve added the 256, 128 and 64 bit encodes with streamnames mp4:${SourceStreamName}\_XXX (XXX = bitrate). I then created a new Stream Name Group called WDET and the Stream name is ${SourceStreamName}\_all.

When I try to play this back, I get this error: The F4M document contains errors URL missing from Media tag

The URL I’m trying is [http://IP:1935/App/ngrp:WDETAAC.stream\_all/manifest.f4m](http://IP:1935/App/ngrp:WDETAAC.stream_all/manifest.f4m)

Thanks!
