When decoding jp2 with palette, [color space] is determined when calling
[opj_decode]. Because of this, [pix_fmt] should be set after decoding.
Otherwise, [pix_fmt] will be set to AV_PIX_FMT_GRAY8 and output an wrong
image.

Starting from Windows 8, users can create SRV from video resource
and bind it to shaders directly. This can avoid unnecessary memcpy
(ID3D11DeviceContext::CopyResource, etc), so create texture with
[D3D11_BIND_SHADER_RESOURCE] as decoder's output if possible.

If we fail to create a decoder specified by ourself, then try to
let VideoToolbox pick a proper one for us.
