Hi again, I have been doing some follow-up experiments going under the assumption that I should do less work in the EOF callbacks. This has lead me to a different problem: The EOF callback is actually getting called before playback is finished, and there appears to be a fraction of a second of media left over in a buffer somewhere. For some reason, that extra 'blip' is sticking around (even if I destroy or just disconnect the current player), without being played, and it is getting mixed in with the next player that I start (even if the player is created several seconds after the EOF has returned). Is this a bug? Or am I just using PJSIP incorrectly? I should also point out that I don't have the option of using a Playlist instead of multiple players because I need to know when individual players have completed. Obviously, the EOF callbacks are not giving the exact behavior that I desire. Is there some other way I could find out when playback is completely finished? Or at least a point that won't result in interference from another player? One player playing at a time, would be nice.
