[MPlayer-dev-eng] MPlayer and raw video

[Mats Peterson]

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.
