Video bigger than DirectX Overlay size.

[gilesbathgate@…]

I have this problem when using directx. When I try to view a
video of 950x540 I get the error message: <vo_directx><FATAL ERROR>can't use
overlay mode: please use -vo directx:noaccel

After supplying -v an error code is also spit out which I have googled and
found to be DDERR_TOOBIGSIZE "Size requested by DirectDraw is too large, but
the individual height and width are OK."

(it might be handy to include something like the following code in the dx
driver to give a better clue as to the problem

I can work around the problem by supplying -vf scale=700

Using this option is obviously faster for me than using -vo directx:noaccel

I would welcome code to automatically detect the direct draw overlay size and
scale the video as needed.
