So, judging from the patch, that is the actual issue?

Yes, in my report, there's output from xvinfo saying that there are no
adaptors present:

mbarsnic at hostname:/tmp/Bui/ffmpeg/ffmpeg-2013-12-25 > xvinfo
X-Video Extension version 2.2
screen #0
 no adaptors present

Darn, I thought I had previously successfully used XVideo on VNC. I
will re-check when I'm back online at work (this was on Real VNC
Enterprise edition).

I just discovered that NoMachine NX has the same issue an said VNC
session. mplayer, with "-vo xv", kindly reports:

[VO_XV] It seems there is no Xvideo support for your video card available.
[VO_XV] Run 'xvinfo' to verify its Xv support and read
[VO_XV] DOCS/HTML/en/video.html#xv!
[VO_XV] See 'mplayer -vo help' for other (non-xv) video out drivers.
[VO_XV] Try -vo x11.

Okay, tough luck for me with the new ffmpeg "xv" output on my display

Thanks anyway!
