Hi, I just had a simple idea for "dynamic cross-fading": use metadata.
Every file comes from a request, which resolution is done by user-definable protocols, which can by the way add some metadata to the request. We actually already have a special protocol named "annotate" which does only this. The URI <annotate:foo="bar":OtherURI> will become OtherURI but will have the extra metadata foo set to "bar". RadioPi's liq script uses this feature in the following way: they have a request.dynamic which calls an external script to get next tracks, but this script does more than just giving a local path, it adds some custom metadata using annotate (name of the scheduling rule in their system which produced the track) and use this custom metadata field in a rewrite_metadata() so that the listeners see the info as part of the title. When the cross-fading works, I could easily make it use the metadata to change its parameters. And you could easily define a protocol for extracting this info, or just use <annotate:..> like at RadioPi. Cheers. -- David
