When VDPAU is being used, letterbox detection does not work.

It looks like there was some unfinished support for VDPAU in the attachment detectLetterboxV9.patch on bug #4872.

Letterbox detection does not work with VDPAU because the code, as currently written, only works with video frames in main memory.

If you want it to work with VDPAU, you'll need to write the code to transfer the decoded frames from GPU memory back to main memory for analysis.

This is still a bug as it is unexpected behavior, regardless of implementation details. Perhaps it can be 'fixed' by stating that zoom auto-detect is unsupported with VDPAU on the settings screen.
