When creating a large number of MediaPlayers, I get this exception:

MediaException: PLAYBACK_HALTED : Could not open audio device for playback.

REPRODUCIBILITY :
This bug can be reproduced often.

CUSTOMER SUBMITTED WORKAROUND :
I found a workaround by remove the audio from the file. This will not allocate any OS audio resources. This actually works better than muting the file, but it's still worth reporting this bug.

ffmpeg -i [in-file] -c:v copy -an [outfile].mp4
