VdpBitstreamBuffer content guarantees
 
Is a VdpBitstreamBuffer guaranteed to contain an entire slice, or does the decoder have to keep track of state and support decoding a slice across multiple buffers and/or decoding multiple slices from a single buffer?

I'm hoping for the former, but if it's the latter does the buffer have to contain complete fields at least, or can a field cross buffers? (By field I mean some multi-bit element from the bitstream of whatever format is being decoded, not an interlaced field or anything like that.)

Thanks.

No, buffer content is completely arbitrary. It's legal, but silly, to have a separate buffer per byte in the bitstream.
