View Full Version : Transcode MP3Pro at SlimServer?

Yeah, that's what I was getting at. If it were possible at the server to
simply distinguish between incoming MP3 and MP3Pro, then you could pass the
MP3Pro stream to a transcoder (e.g. Audion) that you purchased. If I
understand the legal issues correctly, the only potential gray area would be
whether the knowledge required in the SlimServer to recognize MP3Pro would
itself require MP3Pro licensing.

Does anyone know what would be required and whether or not the SlimServer
would need to be a licensed MP3Pro app to make it happen?

but if a SB user owned a validly licensed decoder, it would be nice to
give them hooks to use it in this way.

If there were a command-line MP3Pro decoder, support could be added
fairly easily.

just curious, how would the stream be recognized as MP3Pro rather than
standard MP3? are there distinctive file extensions and/or mimetypes,
or is there some header info in the stream itself?

of course, a workaround would be to use the MP3Pro decoder -- which
presumably also is capable of decoding standard MP3 -- for all MP3 work.
but if the desire was to handle MP3 on the device and MP3Pro in
software, then some detection would be required.

I believe that you can inspect the MP3 data to determine if it's an
MP3Pro stream.
