nvc0/nvc0_video.c: In function 'nvc0_decoder_begin_frame':
nvc0/nvc0_video.c:39:17: error: 'struct pipe_video_buffer' has no
member named 'base'
    assert(target->base.buffer_format == PIPE_FORMAT_NV12);

Oops? I'm guessing you didn't build this with --enable-debug -- don't
worry about fixing this up for now, I'll probably have more comments
later...
