Selective transcoding possible?

[rt1440]

The MinimServer setup I am testing is set up like this:

1) MinimServer on QNAP NAS managing a large collection of ALAC .M4A files

2) Favorite control point: Linn Kazoo on iOS

3) Fixed Renderers: OpenHome Player (MacOS, Windows, RPi, etc.)

4) "Travel" client for iPhones, iPads wanting to download music for trips: fooBar2000 for iOS

I haven't had any success persuading the OpenHome Players to play ALAC .m4a files that are streamed to them (maybe they didn't add that support due to licensing?), but they work fine when MinimStreamer first converts the file to WAV with "alac:wav" in the stream.transcode property of System.

However now when a phone tries to download an album in foobar2000, the album is provided in .WAV format, which consumes more space than ALAC-compressed files.

Is there any ingenious way to configure MinimServer/MinimStreamer to transcode only for OpenHome clients, or perhaps a more general "transcode-but-only-for-these-IP-addresses" type setting?
