[Mp4-tech] MPEG format test

[Anil Gupte]

Re: [Mp4-tech] MPEG format testWe are looking to write a software that encrypts/decrypts MPEG files.  During decryption, we want to make sure that a valid MPEG file is created, so we want the software to do a simple test or something that validates that the decryption was successful.
Thanx,
Anil Gupte

    Is there a test to determine if a file/stream is in MPEG format?  Is there a standard header?  Where can I find out more about this?
  There are various verification tools (ISMA has one) and also the reference software, for the file format.  The elementary streams have their own tools.  Which are you looking for?
    Thanx for the help.
