[MPlayer-users] Greyscale "tricks"

[Meino Christian Cramer]

Hi,

 I have a video stream witch is black and white (grayscaled).

 "From the physical point of view" one would only need one "color"
 instead of three to encode the video stream in greyscale but as I
 understood the documentation all available colorspaces are "three
 dimensional" (but may be I am wrong).

 Are there any more options to mencoder to save file size/to increase
 quality others than the grayscale encoding option for the lavcodec --
 not only concerning colorspace?

 Any help is very appreciated!

 Thank you very much for any hint in advance!

 Kind regards,
 Meino
