You tried to play media file in Parole Linux media player, but it says:
"GStreamer backend error"
"Could not initialise Xv output"
It is many years known bug. Solution is mentioned at https://leo.unglaub.at/howto/openbsd/parole-could-not-initialise-xv-output/
It is to click "Tools" menu, select Preferences, go to "Display" tab and change Video output to other option.
