I ran across some videos from a client that we needed to use in a deposition that would not play in VLC. I got an IMM5 CODEC error. I can't find any information just about anywhere on that CODEC (plenty on IMM4), and I'm wondering if there is such a thing for VLC.
I ended up using the Windows Media Player in WIN10 Pro and turning on captions, as we needed the date/time stamp to display but would like to be able to count on VLC in the future because this would not play in WIN 11 native apps.
