ReplayGain

[simoncn]

This all makes sense to me. To answer your questions:

Quote:Is it technically possible for a UPnP server to supply ReplayGain info to the control point when the latter is browsing the media tree?

I don't think there is any UPnP standard property for passing this information.

Quote:When the renderer plays the audio file, does it get the complete audio file including the ReplayGain info (provided that transcoding is not used) or does it only get the audio data? In the latter case, would it be technically possible to supply the ReplayGain info in a different way?

If transcoding is not used, the ReplayGain information is available by reading the file's tag metadata.

If transcoding is used, the metadata is removed by MinimStreamer and the ReplayGain information is not available. In theory, MinimStreamer could insert the ReplyGain information but this would be a significant amount of work and could only be justified if there is some significant probability that it might be used by the renderer.
