It's always helpful to post the complete command output to see what's going

please do not top-post on this mailing list.

Done encoding or done playing/streaming?

I see two possibilities right off-
First is that the second video is added to the playlist -after- the first 
has completed (and the player stops because it's hit the end of the list).

Second is that the player only reads the playlist at start and never sees 
that it's been appended to.

You could easily test this manually by pre-encoding the videos and 
hand-editing the playlist at different points in the timeline.

What's the timeline of when entries are made on the play list, when videos 
start and stop, and when they're encoded?

Later,
