2011-08-15 v0.9.7-p1 "Cayuga" patch 1 This is an incremental bugfix release against Cayuga. All users of that release are strongly encouraged to upgrade. - Fix potential OOB reads (cdae03a) An unbounded out of bounds read was discovered when the decoder was requested to perform error concealment (new in Cayuga) given a frame with corrupt partition sizes. A bounded out of bounds read was discovered affecting all versions of libvpx. Given an multipartition input frame that is truncated between the mode/mv partition and the first residiual paritition (in the block of partition offsets), up to 3 extra bytes could have been read from the source buffer. The code will not take any action regardless of the contents of these undefined bytes, as the truncated buffer is detected immediately following the read based on the calculated starting position of the coefficient partition. - Fix potential error concealment crash when the very first frame is missing or corrupt (a609be5) - Fix significant artifacts in error concealment (a4c2211, 99d870a) - Revert 1-pass CBR rate control changes (e961317) Further testing showed this change produced undesirable visual artifacts, rolling back for now.
