If i do 'mpv -v -vo vdpau --vd=ffh264vdpau,ffvc1vdpau, movie.m2ts' , i get a high cpu usage. So indeed hardware acceleration does not work. However, if i use 'mpv -v -vo vdpau --hwdec=vdpau movie.mt2s' , i get a nice low cpu usage. So mpv is not affected as long as one uses the new way of choosing hardware acceleration. I believe mplayer2 is no longer in active development. The website 'mplayer2.org' is dead. So chances are small this (i.e. the API changes in libav) will ever be repaired in mplayer2.
