Unplayable mjpeg2000 file

Dale Powell
Hi list.

I have this file from one of our video suppliers at work, it is the source file as the video is saved on their servers and comes with an unknown to me .blt extension. I have not managed to get it to play on anything, even changing or removing the file extension to try and get MIME type picked up from header information. Running ffprobe I get the following output. Can anybody let me know if there may be a way to view this file, and eventually probably want to create a batch script to convert to ProRes or similar...

Anyway; the output of: $ ffprobe ~/Desktop/20181118_PUNCHESTOWN_R5_YG

Here I am running Manjaro Linux on my personal laptop but finally we would hope to be converting on OSX.

Kind regards, Dale.
