As previously discussed, the CrystalHD hardware returns exceptionally useless information about interlaced h.264 content - to the extent that it's not possible to distinguish MBAFF and PAFF content until it's too late. This change introduces use of the h264_parser to help bridge the gap; it can indicate if the input data is PAFF fields or not. With this clarity, some of heuristics can be removed from the code, making this less convoluted. Finally, I found an MBAFF clip that acts like non h.264 content so I had to make allowances for that. Note that I still cannot distinguish between two forms of PAFF, where the hardware either returns individual fields or a field-pair. It's not clear that there's even a spec relevant difference between the two forms, as opposed to hardware ideosyncracies.
