Are there any plans for future support of AC3 decoding on the Wowza trancoder? As it stands I have to take my live streams in and transcode the audio to a compatible format before redirecting through Wowza, this is less than ideal. If you do not have plans for AC3 support is there a developer’s kit for adding that functionality ourselves? Thanks for the help! ---

Thank you for your input. I’ll pass along your request to our product management team. Not sure when this support might be available. There is not currently a way to add support yourself. -Lisa ---

Thank you for the details and your interest in Wowza Transcoder. This helps us better understand your workflow and I will pass this additional information on to our product management team. I still don’t have an update on when this may be available. -Lisa ---

We don’t have a Wowza developed workaround or any early release build with AC3 support. -Lisa ---

This is a serious difficulty in our evaluation. Set-top boxes might be connected to “surround sound” speaker deployments (5.1, 4.1, 7.1, for examples) – and for them get the “surround sound” from the dolby digital stream (AC3), we will need either support for AC3 streams from wowza for “AC3 passthru” – or some way to transcode to at least 4 channels of AAC (if that is even possible). This isn’t just theoretical, either – I have a stream from an hdhomerun that is handing me AC3 audio, which wowza is not accepting. (_Yes_, I can transcode it with ffmpeg or vlc – but we’re trying to avoid pre-transcoding streams as much as possible.) Help? ---

Thank you Lisa. Is there any workaround that Wowza has developed, excepting using vlc or ffmpeg to “pre-transcode” the audio before Wowza gets it? Thanks, ---

Hi, Any update on this? Seems that a lot of Wowza customers are requesting to support AC3 decoding for many years. Is this a technical of political challenge? - Joost ---

Hello, Unfortunately there’s no update or addition yet. Currently the only option with AC3 is pass-through the AC3 audio stream to compatible clients. Best, JasonT
