-------------------------------------+-------------------------------------
 The color space that ffmpeg uses on FRAPS videos seems to be wrong or
 mishandled.

 First, running ffplay on a video (color space detected as yuvj420p), the
 output looks washed out (too white).
 Second, when transcoding a video to H264 (which keeps the color space as
 yuvj420p) the output looks too dark. Forcing the color space to yuv420p,
 the output looks fine.
 Third, when transcoding a video to MPEG2 (which changes the colorspace to
 yuv420p), the output looks fine.

 Here is how ffmpeg detects the original file:
