Sure some codecs are not supported, but I thought this was your intent 
because ::get_format() has to check for it anyway. i.e. the API can 
specify support for a codec but the user has to check the HW actually 
supports it. So, even if we add the HW formats on per-codec, there are 
cases were it wouldn't be supported for real. e.g. VDPAU VC-1 in the past.
