mpeg-4 filter   

Hello,

I am looking for a free mpeg-4 DirectX filter which is capable of
getting the duration of a selected mpeg4 file.

the k-lite codec pack and ffd-show pack are capable of playing an
mpeg-4 file but don't give a correct answer for the IMediaSeeking-
>GetDuration().

I found that the 3ivx filter does the job, but it is not free...

Any help on getting such a free filter is highly appreciated.

Thanks

What is the file container format?  AVI, MP4, MPEG-2 TS, MKV ...

It is the parser that responds to the GetDuration() request, not the
decoder.

What do you mean the parser? then what shall I do in order to solve
this?
How can I learn what is the container format?
Thanks

A parser filter, also known as a splitter filter, takes the original
container format and splits the streams into two or more streams on
separate output pins.

From "About DirectShow Filters" in the docs:

"A splitter filter splits an input stream into two or more outputs,
typically parsing the input stream along the way. For example, the AVI
Splitter parses a byte stream into separate video and audio streams."

First, answer Chris' question about the container format.

Also, are you writing a commercial project or a free one?

It's usually indicated by the extension on the original file (.avi, .mp4,
.mp2, etc.).
