Comment (by Michael Koch):

 I suspect the problem is in line 70 of dshow.c, but I can't make a test
 because I can't compile FFmpeg under Windows.

 "RGB8" is in the Directshow documentation defined as "RGB, 8 bpp,
 palettized".
 "AV_PIX_FMT_RGB8" in FFmpeg is defined in line 86 of pixfmt.h as "packed
 RGB 3:3:2, 8bpp, (msb)2R 3G 3B(lsb)".
 These are two different pixel formats.

 Shouldn't line 70 in dshow.c be changed to AV_PIX_FMT_PAL8, and the
 palette must be loaded from the DirectShow driver?
