Ronald S. Bultje	c742ab4e81	vc1parse: call vc1_init_common(). The parser uses VLC tables initialized in vc1_common_init(), therefore we should call this function on parser init also. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org	13 years ago

Mashiat Sarker Shakkhar	d51d6ae9c4	vc1dec.c: Don't use uninitialized values of dmv_[x, y] MVDATA may or may not be transmitted. If it is not, both dmv_x and dmv_y is to be assumed zero. This may not trigger wrong picture in all systems, but it's a bug nevertheless. Fixes SA10116.vc1 on my 64-bit Windows 7. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	13 years ago

John Brooks	d209c27b09	vc1dec: fix invalid memory access for small video dimensions For small video dimensions, these calculations of the upper bound for pixel access may have a negative result. Using an unsigned comparison to bound a potentially negative value only works if the greater operand is non-negative. Fixed by doing edge emulation when the upper bound is probably negative, everywhere that this pattern appears. Signed-off-by: Kostya Shishkov <kostya.shishkov@gmail.com>	13 years ago

shahriman AMS	4344ce08f1	vc1dec: Partial rewrite of vc1_pred_mv() The current code is a generalization of the earlier progressive MV prediction code. This was supposed to predict MVs for both interlaced and progressive pictures. But the interlaced MV prediction is buggy and works mostly by luck. This partially fixes interlaced MV prediction.
