The *roAudioPlayerMx* object can generate *roAudioEventMx* messages with the following values:

- 8 EVENT\_MEDIAENDED
- 14 EVENT\_OVERLAY\_MEDIAENDED
- 16 EVENT\_MEDIAERROR
- 17 EVENT\_OVERLAY\_MEDIAERROR

"Media ended" events are sent when a track finishes and there are no more queued tracks for the player, while "Media error" events are sent when a queued file is not found (e.g. when it does not exist).
