Is it possible to receive a live rtsp stream from an ip camera and then use the trancoder addon to only stream the audio in AAC+ format?

Yes you can. Use “disabled” for video encode. Use .stream files to contain the rtsp url, and start the stream in StreamManager to start the Transcoder.

That’s a HLS url.

The proper form is: [http://ip:1935/rtplive/x.stream\_aac/playlist.m3u8](http://ip:1935/rtplive/x.stream_aac/playlist.m3u8)

What protocols does the devices support?

Ok so I did.

Transcoder template:

true

RTP

${SourceStreamName}\_aac

Disable

AAC

${SourceAudioBitrate}

The problem I am having is the header that is send: Content-Type: application/vnd.apple.mpegurl

with this url: [http://ip:1935/rtplive/x.stream\_aac/playlist.m3u](http://ip:1935/rtplive/x.stream_aac/playlist.m3u)

I need the content type to be: Content-Type: audio/mpeg

Is this possible and what url should I use?

It’s for a hardware device that accept streamed audio in AAC+ but checks the header and refuses it.
