[Xine-vdpau] software equalizer (Gamma correction) not working with vdpau

[Christian Neumair]

Dear xine-vdpau developers,

using the Ubuntu Karmic the-vdr-team svn build based on xine-vdpau svn
revision 284, I was unable to get xine's software equalizer to work.

mplayer -vo vdpau -vf eq2=2.0 <somefile.avi>
xine -V opengl --post eq2:gamma=2.0 <somefile.avi>

correctly sets the Gamma correction to 2.0. On the other hand,

xine -V vdpau --post eq2:gamma=2.0 <somefile.avi>

does not seem to work, i.e. the xine vdpau video output ignores the
Gamma correction - the software filter chain does not seem to be
applied.

My use case involves vdr-sxfe which is based on xineliboutput, for
applying Gamma correction for a presentation beamer that was not made
for movies and TV. I'd also be happy if the xgamma setting was applied
on the vdpau window, but this does not seem to be the case. Any ideas?

best regards,
 Christian Neumair
