I am streaming live music performances from the web using Flash ActionScript to Wowza 4. Downstream, we are using both RTMP and HLS streams. Since we are streaming music we are using the NellyMoser codec because Speex does not provide us with the same audio quality. The HLS stream requires the audio to be encoded as AAC in order for it to work. Unfortunately NellyMoser cannot be transcoded to AAC using the Wowza Transcoder addon because NellyMoser is proprietary.
Is there some way that we can pay a license fee to transcode NellyMoser to AAC using the transcoder? Or does anyone have any other solution for this problem. The requirements are:
- streaming from the web using flash
- audio and video available on all devices downstream
- high quality audio w/ minimal compression for live music
Hello Jonathan, welcome to the Wowza support forum.
I had a quick search of Google for transcoding NellyMoser to AAC via FFmpeg. I found plenty of discussion and a few claims that it was successful. Although I have not tested it. Might be something to look into. Another option to research would be VLC.
The Wowza Transcoder supports Speex as an input source to be transcoded to AAC. If you choose to test this or go this route, you can follow this guide to convert your stream to the supported codec for the Transcoder:
