Well, because I didn't know about this field and someone would  
probably say why not PixFmtInfo.pixel_type == FF_PIXEL_HWACCEL? This  
could also make sense considering the actual pixels are in GPU/VPU/ 
whatever memory. The other reason why I will stick to is_hwaccel:1 is  
because I already had a patch lying around, it's just a matter of re- 
applying it. ;-)

So, if someone really objects against my new bit-field proposal,  
please say specifically what to use and I will write the new patch
