Play MP4 in Media PLayer


I am using mp4 files myself. Rather heavily. The files I have use the native h264 codecs for video and also something pretty standard for audio and they work. MP4 is a container format and I vaguely remember I once had a file, that did not play.

I am not a real expert here, but you can try this:

Download the static Windows version of ffmpeg and check your mp4 file with ffprobe.exe. It will output a bunch of information about that file, including the codecs used inside it. Knowing these codecs is a first step on the way to a solution.
