Romain Beauxis updated LS-318:
------------------------------
Summary: harbor/http/..? buffer consistency after overruns. (was: some
strange things while using 2 harbor sources at once)
Ok, I think I finally understood this one..
The problem is that the harbor for the playlist keeps receiving data while the
first harbor is broadcasting.
The result should be consistent audio in the buffer after an overrun.
Should be easy to test and fix. Are there any other sources that could have
similar issues? I can think of input.{http,lastfm}.

> Hi, Savonet Team!
> I have 2 harbor sources that can be used together. one for external playlist
> stream generator, another for live performances.
> this 2 sources joins into one source using swhitch operator. it is very
> useful for me, as i can make transitions between live and playlist, and if
> live doesn't starts at time playlist continues to play.
> now about stranges: after live connect-play-disconnect i can hear a short
> parts of a tracks that were streamed to playlist during live was on air. just
> about 10 - 30 secs per track. the closer it gets to current time the longer
> part is. this sounds very interesting as listeners can hear a "review" of all
> tracks that were played in playlist during live, but this is not the thing
> that i expect to get.
> well commented log and config are attached
