Avidemux: Where are OpenGL filters?..

[Marco Bux]

Hi.
I installed Avidemux 2.6.10 Windows 7 32bit.
In the filter menu I can't find any OpenGL entry.



I also tried to enable OpenGL support but when I restart Avidemux the flag is still disable and the OpenGL filter list is empty.



Can anybody help me to unravel the mystery?...

Thanks in advance.
