Re: [webrtc-stats] which qp range is used for AV1? (#799)

It's a little strange to me that we chose the 0-63 as input, as that's not a range at all defined by the bitstream spec - rather it's a "convenience" feature of the libvpx/libaom implementations in order to keep parameters similar between codecs. For a raw interface like WebCodecs I think the bitstream spec would have made more sense (and allowed more granular bitrate control), but I fell it's too late to update that specific part of the API...

Also I wonder how many implementations _actually_ support the QP = 0 level, as that implies the highly specialized lossless encoding mode.
