Restriction of BBC Radio HLS/DASH to authorised third parties

The audio information should be [aac:48000] not [aac,96000]. The number is the sample frequency, not the bitrate.

As it is working without ffmpeg and transcoding, I suggest you leave things as they are. Transcoding doesn't add functionality but can give an improvement in sound quality in some cases. For an aac radio stream, the sound quality improvement would be marginal at best.
