[MPlayer-dev-eng] [PATCH] Stereo3D: Basic Row-Interleave Output Support

[Steaphan Greene]

I finally picked up a passive 3D display (I can't tolerate the flicker
of active-shutter glasses), and found it really handy for mplayer to be
able to output 3d images in its native, row-interleave (every-other-row
for each eye) format.  The stereo3d video filter was 99% there, so I
added the attached hack (a patch based on current SVN).  This adds two
more stereo modes for 3d output (only, not input):

	"irl" or "interleave_rows_left_first"
	"irr" or "interleave_rows_right_first"

I didn't implement these for input, and I didn't do anything beyond this
filter (so, no documentation changes, and, for example, to show a 720p
side-by-side stereo movie full-screen on a 1080p 3D display, you have to
scale it to 1080 lines with the "scale" filter first, or the interleaved
lines won't line up after scaling to full-screen.


Note, I am not suggesting this patch be applied to the mplayer SVN.
This patch it not that mature, it's just a quick hack (and not well
tested).  I am providing it here in case it might prove useful to
others, as it does to me.

Of course, you are more than welcome to include it, or a derivation of
it in mplayer, if you still feel it is appropriate to do so.


Thanks to all who've helped provide mplayer/mencoder to us all!
