Stream start - wrong channel data output #2

Closed keynet closed 4 years ago

keynet commented 4 years ago

Hello again. I've been using ts2shout daily for a couple of weeks now, it's working well, but I've observed an occasional problem with stream startups. Below is an annotated example from a stream start this morning. Data is always correct (and doesn't go wrong) once the stream is fully established. It appears data from another stream is being output during the stream startup process.

(Correct) 14/04/2020 08:55:00 album/stream=BBC Radio 4 (Freeview), artist/title=Today, track/desc=News and current affairs, including Sports Desk, Weather and Thought for the Day
(Partial, but correct) 14/04/2020 08:54:47 album/stream=BBC Radio 4 (Freeview), track/desc=BBC Radio 4
(Data from a different stream + garbage) 4/04/2020 08:54:47 album/stream=BBC Radio 4 (Freeview), artist/title=The Repair Shop, track/desc=3/14. Jay Blades and the team tackle a torn leather armchair, a broken music box, a faded portrait and a shattered stained-glass door panel. Also in HD.

Could you please send me the output of ts2shout (written into the apache error-log). Data from another stream (inside the multiplex) could be possible and would be a bug. Old data (from a run of the software earlier) is very unlikely (because ts2shout just reads from stdin or makes a "fresh" fetch with libcurl).
