Hi,

We've been using resolvePlayAlias (by implementing IMediaStreamNameAliasProvider) to map an alias to an actual feed. It works as expected when calling the alias directly but if we use a SMIL file that references the alias, resolvePlayAlias() is not called at all. As a result, the alias does not get mapped to the actual feed and playback fails.

Here's the log output for an HLS request for the alias 'feedalias' which should map to the actual feed 'feed':

And here's the log output for an HLS request for the SMIL file feedalias.smil which contains a single entry for the alias 'feedalias':

As you can see from the logs, resolvePlayAlias() is called multiple times for a direct feed request but is skipped completely for a SMIL file request. According to the post here: http://www.wowza.com/forums/content....der2-interface, this should work for SMIL files as well.

Is this a known issue? We're running Wowza 3.6.4.01.

Thanks.
