@@ -103,6 +103,28 @@ OpenGL's GL_RGB on all platforms, and the same goes for BGR - GL_BGR.
Unfortunately, most of the x86 codecs call our BGR to RGB, so it sometimes
confuse developers.
-If you are unsure, try the OpenGL driver (-vo gl:manyfmts). There is at least
-software OpenGL implementation for all major platforms and OS's, but you will
-need OpenGL version >= 1.2 for most formats.
