Noisy screenshot from mplayer -vo xv
On a Broadwell system (X1 Carbon 3rd generation), playing video through the
default xv adaptor "Intel(R) Textured Video" adds piles of green and purple
noise to the image. I can reliably reproduce this by playing back any video
using "mplayer -vo xv". This noise doesn't appear when using some other video
output (such as -vo gl) or when using xv adaptor #1: "Intel(R) Video Sprite"
(though that has other issues).
I'll attach three screenshots of the same video frame: one from mplayer -vo xv
(showing the noise), one from mplayer -vo gl (not showing the noise), and one
dumped via mplayer's internal screenshot mechanism by hitting alt-s (which
turns a frame into a screenshot without sending it to the video output, so it
doesn't include the noise).
The noise doesn't dance around; it's consistent for any given frame, and slight
changes to the frame seem to produce slight changes to the noise rather than
completely different noise.
