Is there a good solution for playing a compressed video in OpenGL?
It needs to
- Be cross-platform (Windows and MacOSX)
- Render to a texture (preferably but not 100% needed)
- Cost less than Bink
Any ideas?

A:
Qt can be used to render widgets (including a video player) in an OpenGL scene. It has a multimedia framework called phonon that can play video and audio.
See this demo video.
Qt is cross-platform and is now licensed under LGPL.

Good answer, impressive demo, but our company is looking to avoid QT.

I know this question is old but : Why do you try to avoid Qt? Nothing prevents you to use it freely in commercial products since version 4.5 is published under LGPL.

A:
I recommend the Theora video format.
Here are the benefits:
- Totally open, free and patent-unencoumbered specification
- Free working library implementation (encoder/decoder) and source-code examples, available under a BSD-style license
- Not too shabby documentation.
- Portable
The decoder lets you decode to R'G'B', which can easily be uploaded with an OpenGL buffer object and fetched in a shader via a sampler.

A:
if you mean by solution that you can build/code it, i can suggest quicktime (easy on mac with cocoa, strange on windows but it works) or you can checkout mplayer/vlc sources and try to integrate that. there are a lot of demos about this on the web.
since you need cross platform, i guess gstreamer, video4linux and directshow are nothing for you. but there are video players that support different backends on different platforms - like openFrameworks
