For AV1, decoder frame threading is related to encoder (bitstream encoded) too.
CDF tables can be updated (or not updated) at the end of decoding for a frame, depending on a frame header syntax element in the bitstream.
If the CDF tables need to be updated at the end of the decoding for a frame, then frame threading should be impossible.
