These two tables can use uint8_t. Or given that they are only used via
rv60_quants_b[rv60_chroma_quant_[ad]c[qp]] one could replace them with
uint16_t arrays that avoid the indirection.

You do not need full VLC structures, only VLC.table is ever used,
because all VLCs here use nine bits. So you can replace e.g. cbp8_vlc by
static const VLCElem *cbp8_vlc[7][4] and switch to ff_vlc_init_tables()
(replace the int offset by VLCInitState for this).

Don't do this. Just store uint8_t *avg_buf[3] and int
avg_buf_linesize[3] and switch the two functions using avg_buf to accept
the data pointers and linesizes separately (for the output frame, not
for the ref frame).

ff_reget_buffer() might have to perform a full-frame copy. Why do you
use it?

This seems to have been copied from VP8; but the check is always false
here and ff_thread_finish_setup is unnecessary, as this decoder does not
support frame threads.

Why not check for frame->data[0]? Seems clearer to me. And it would work
if one implemented low-delay (i.e. where it is presumed that no b-frames
are present).
