Subject: Skip unnecessary search of identical frames
X-Git-Tag: v0.9.5~110^2~1

Skip unnecessary search of identical frames

vp8_get_compressed_data() was defeating logic in
encode_frame_to_datarate() that determined the reference buffers to
search and forcing all frames to be eligible to search. In cases
where buffers have identical contents, this is unnecessary extra
work.
