I'm writing a DirectShow application using the lencmpga2.dll encoder. Can you tell me how to modify the filter settings from a .NET application? As far as I can tell, the DLL doesn't expose any COM interfaces.

Thanks,
Jeff

Jeff,

If you are
using the LEAD MPEG-2 Encoder, you can access its programming COM interface by
adding it as a reference in your .NET application. The interface is documented
in the help topic named "LEAD MPEG-2 Encoder" in our LEAD Multimedia Filters help file.

Adnan,

Thank you for the reply. I have been successfully using the MPEG-2 Video encoder COM interface. It's the MPEG-2 Audio encoder that I'm unable to configure. Attempting to add it as a reference to VS fails, and the documentation lists N/A for interfaces.

If you mean the LEAD MPEG Audio Encoder (2.0),
this is not an MPEG-2 encoder to be exact, and the help file is correct. There are no options you can set, and therefore, there is not programming interface.

Yes, I was referring to the MPEG Audio Encoder 2.0. Pardon the typo.

Just to confirm, is there really no way to set the bitrate or frequency of the audio when using this codec?

Yes, it
will not be possible for you to modify the Bitrates or frequency since the MPEG Audio does not have a programming interface.
