Meaning
MP4 is a media container format used to package timed streams and metadata; it is not the name of one video codec.
A practical example
A handoff can describe an MP4 containing H.264 video and AAC audio rather than simply promising an MP4 file.
What to check
Do not assume every file with the extension plays identically. Inspect codecs, duration, track layout and the intended playback environment.
