If the aspect ratio flag is unreliable, again, you can always just use
the resolution and calculate it.

If you want to limit the plugin to using only the hardware then I
agree. However, if you want to provide capabilities beyond what the
hardware is capable of then software is the only other place to do it.
This is perfectly fine, although it probably means the user wasted
his money on a hardware decoder if he's just going to do software
decoding anyways. It doesn't hurt to put more consideration into what
you want/need before pouring money into hardware. I know guys that
threw a lot of money at hardware decoders only to replace them with
cheap vdpau-capable video cards. To each his own I suppose. :)
