[MPlayer-users] PGS, -vf scale and artifacts.

Recently I noticed that PGS subtitle rendering, when used in conjunction
with the scale filter and some, but not all, vo drivers, results in some
highly noticeable artifacts along the right edge of the "bounding box"
that the subtitles are contained in on screen. For example:
mplayer -v -demuxer lavf -sid 0 -nosound -vo xv -vf scale=1280:720 pgs_and_vf_scale_artifacts.m2ts
This works if I change the -vo driver to vdpau or gl, or if I remove the
-vf scale invocation.
The problem also occurs when using mencoder, which is where I first
noticed it. (It took me a while to convince myself that it wasn't
simply a case of the encoder introducing artifacts in the face of hard
subtitles.)
I have a small (less than 100MB) sample file that demonstrates the
problem, but I would prefer not to upload it to a public space. It is
available over http at a URL that I can share in private communication.
Below are some details as requested in
<http://www.mplayerhq.hu/DOCS/HTML/en/bugreports_what.html>. My system
is a semi-up-to-date Debian unstable install, using the proprietary nvidia
driver version 256.53.
I would appreciate any help that anyone can give me. If there is
anything else I can do to investigate the problem, please do let me know.
~Gaute.
