Within the last week I've noticed that my MKV and MP4 files will either not play at all or play with no sound. Any file over 3gb is where this problem is happening. The frustrating part is I've had these files for awhile and they used to play but now I'm having problems. I experience this problem playing via WMP and streaming to TV which again use to not be a problem. Any help to get things back on track would be appreciated!
honestly it's been so long I can't remember the codecs I originally downloaded to get it working. Is there anyway I can look that up? I can't understand why they all of sudden stopped working when they used to work.
Could also try mpc-hc. It is self contained, so if it works you know it is a codec issue within your media foundation. Best thing in that case is try a restore point or uninstall every codec you have and start over. Worse case, a reinstall.
