Automatic advance does not work, autorepeat does not too. SMPlayer just gets paused at the end of the video or music.
OS: Linux Mint 15 Olivia
SMPlayer: 0.8.3, 0.8.6
Please send the smplayer log (options -> view logs) after that happens.
Does the problem also happen if you use mplayer instead of mplayer2?
No, it doesn't.
From the log it seems that mplayer2 doesn't finish correctly.
SMPlayer expects the line ID_EXIT=EOF or Exiting... (End of file) to know that a file has come to the end, but for some reason it seems in your case that line is not displayed, that makes me think that maybe mplayer2 crashed just before exiting.
It is possible that new MPlayer does not display that line anymore. May be exit status should be analyzed instead?
I've just compiled the very latest versions of mplayer (SVN-r36426) and mplayer2 (9d6b188) and both display the ID_EXIT=EOF string when a file gets to the end.
So, I suppose, this should be closed as third-party problem.
I tested the live DVD of Linux Mint 15. I could reproduce the problem with mplayer2. I noticed that mplayer2 is actually downloaded from the ubuntu raring repository.
If I play a video directly with mplayer2, the mplayer2 window is not closed when the video gets to the end, so it's clearly a bug in mplayer2. Actually the bug is already reported here:
