Meaning
A video codec defines how visual information is encoded and decoded for storage or transmission.
A practical example
Two MP4 files can use different video codecs even though their filename extensions match.
What to check
Container and codec are separate choices. Check the actual stream metadata and intended decoder instead of using the extension as a compatibility test.
