Hi,

Using the WMS transcoder add-on, i want to set up an encode to ‘stream out’ an audio-only stream. What i did in my trancoding template was the following:

- Set the tag with the value **'aac:audio’**

- Within the tag, i changed the value to **'Disable’**

- Setted up audio tag to **AAC** and tag to **64000**

- I’m getting A LOT of logs like this one -\> **TranscoderWorkerVideoEncoder.run[videoEncoderAddFrame][audio]: 4294967295**

- I added the audio-only stream to a smil file this way -\> . However, this stream does not appear nor in the manifest nor in the playlist.m3u8
