It depends a bit where your choke points are at those speeds. If you
process things at 8x, 16x or 32x, you might find that the
demuxer/parsers start using way too much CPU, or that data can't be read
fast enough from storage/network, or that all those unaligned memcpys
are really starting to bite. In those cases, the demuxer might need to
avoid unnecessary processing to make things work at all.
