Since there for some reason hasn't been any response to my previous posting, here we go again: MPlayer naively assumes that 'rawvideo' raw video from libavcodec (whether it's contained in AVI, QuickTime or something else) contains 24-bit RGB triplets. It *can*, for pixel formats like rgb24 and bgr24, but it can also be less than 24 bits (palettized, grayscale or monochrome). Anything that's not compressed/encoded. What's more, MPlayer misinterprets a negative height in the BITMAPINFOHEADER for AVI files as being a very large unsigned value, rather than the indication of the video data being arranged top-to-bottom rather than bottom-to-top. The files below with raw video will play without video in MPlayer.
