crash in exitEvent when using player argument to get info about the player that just exited

[Gillissie]

Issue Report

Description

The exitEvent callback takes two arguments: player and exit_status. If you call something like player.get_filename(), the program crashes with an OMXPlayerDeadError.

It seems to me that the player is cleaning everything up before calling the exitEvent, making the player argument pretty useless to find out info about what just exited.

Problem reproduction

from omxplayer.player import OMXPlayer

def video_exited(player, exit_status):
    print("video exited: {}, status: {}".format(player.get_filename(), exit_status))

VIDEO_PATH = "Your Video File Here.mov"

videoPlayer = OMXPlayer(VIDEO_PATH,
                  args="--win 0,0,1024,768 --layer 1",
                  dbus_name="org.mpris.MediaPlayer2.omxplayer1")

videoPlayer.exitEvent = video_exited

# Press return to force the video to exit before it ends naturally.
input("Press Enter to continue...")

videoPlayer.quit()
