Finding out mpeg format

[DEmberton]

Hi,

Does anyone know of a free tool, library, bit of code that will give me format info of an MPEG2 file? Basically this is for a bit of software and I want to check to see if an existing file is compatible with my output format to decide if it needs re-encoding.

Thanks.

Thanks, but that's a GUI tool. I need either a command line program with a simple output, or a library.

mpgtx has an information mode. It is an opensource tool, so you should be able to look to see how it retrievies its information.

Which programming language?
I could give you some VB6 code if you are interested...

Also some code can be found in Project X (in java)

[DEmberton]

Well C++, but I can probably figure it out from other stuff.

Is there not a simple header in a .mpg file?

Well you can use MediaInfo:

DLL, library etc.

or DirectX, depending on what your application target is, which has lots of interfaces for this.

More or less, yes. It depends on the information you need. Actually mpeg is stream data, therefore it can be started or interrupted more or less at any place. There are different headers spread over the file.
Send me a PM with your e-mail, I can send you my VB6 code and some add Info.

Or have a look here (in the Source code section):
