Comment:

 The issue of deinterlacers no longer working after falling back to
 software decode should be fixed with the changes to the deinterlacer
 setup.

 Falling back to an entirely different profile is something I'm aware of.
 It is currently complicated by the need to coordinate between the decoder
 and videooutput classes i.e. if hardware decoding fails, the code could
 fallback (fallthrough) to the next profile but it is not clear how that
 would be interpreted for rendering - and might produce unexpected results.

 Realistically there are few situations where an alternate hardware decoder
 is a useful option (VDPAU to NVDEC perhaps being one exception) - although
 falling through to a clearly defined software decoding profile is
 preferable (as this will allow e.g. deinterlacing preferences to be set
 properly).
