.avi File format output

[Stanley Fok]

Hi,

I'm writing a simple Directshow capture program and i would like to
output the recorded stream to an avi file. I can do this fine using
the

ICaptureGraphBuilder2::SetOutputFileName

function as in the samples, however, the output file is always a
32-bit avi when i only need an 8-bit avi. Does anyone know if there's
a way to force the file writer to output an 8-bit avi?

Thanks,

Stanley
