Arguments in ReceiveProc equate to one byte per pixel?

I am using the ReceiveProc method in a callback filter:
Width = 352, Height = 240, Bitcount = 8, Size = 84480 (bytes). If my math is correct (352x240=84480), this equates to one byte per pixel. This is a high color video image, and I would think there would a minimum of one byte per channel, or a size of at least 337920 bytes. The resultant image's colors are quite flattened out. I am using the Microsoft MPEG-4 v2 filter. Could this be causing the size argument to be so small?

If the Bit Count parameter of
the callback filter's ReceiveProc is 8, this means the image is actually one byte (8 bits) per pixel.

If you want to see how the
toolkit builds the filter graph internally, and which filters are used exactly,
by adding a call to our EditGraph() function after the filter graph has started
running. This could tell you how and where the image got converted from 24-bit to 8-bit.

 

To see the graph, you'll need
the Microsoft DirectShow GraphEdit utility. If you don't have it, you can get it from the following post on our forum:
