nailer not working with vo=vdpau

[Julian Sikorski]

Hi list,

due to the fact that a particular totem bug [1] is not getting fixed I
have decided to give nailer a spin. I have found 1 bug in the rpmfusion
package, but even after fixing it the thumbnailer was not working. It
turned out that it did not like that I had
vo=vdpau:hqscaling=1,
set in my ~/.mplayer/.config. Thubnail generation would fail with the
following message:

$ nailer -v
file:///media/realcrypt1/tv/Two%20and%20a%20Half%20Men/Two.and.a.Half.Men.S11E20.720p.HDTV.X264-DIMENSION.mkv

The selected video_out device is incompatible with this codec.
Try appending the scale filter to your filter list,
e.g. -vf spp,scale instead of -vf spp.

Too many buffered pts

Can something be done to work this problem around? It seems strange that
-vo null from command line is getting overridden by vdpau from the
command line.

Best regards,
Julian

Please excuse me answering to myself, but it is vc which is the problem
and not vo. This means nailer needs to ensure potential vc entries are
overridden.
