Ronald S. Bultje	844799b033	vp9: invert order of two conditions. This makes it equal to row-based loopfilter code, and also makes the chroma/luma code identical.	10 years ago

Ronald S. Bultje	ed45edb2f6	vp9: use aligned size to write segmentation map into cache. The unaligned size is not handled in setctx_2d(), causing edges of images to have improper segmentation prediction, which causes visual artifacts at image edges a few frames later.	10 years ago

Ronald S. Bultje	c82e870c12	vp9: maintain lf_delta values if feature is turned off. This is required if it's subsequently re-enabled with no value updates (which means, use values that were previously set). Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	10 years ago

Di Wu	162b521108	vp9: enable multi-thread decoding when refreshctx is equal to 0 In vp9_decode_frame function, ff_thread_finish_setup is not called when refreshctx is equal to 0, and the next decoding thread can not start work until the cunrrent frame has been decoded completely. So ff_thread_finish_setup needs to be called to enable Multi-thread decoding in this condition. Signed-off-by: Di Wu <di1028.wu@samsung.com> Signed-off-by: Reynaldo H.

Ronald S. Bultje	21a0451167	vp9: split decode_coeff_b loop inside txsz branch. The advantage of this is that the is32x32 division branch in decode_coeffs_b is removed from the inner loop to outside the block coef decoding loop in decode_coeffs. Also, it allows us to merge the txsz branches from the block coef decoding loop, the context merge and the context split.	11 years ago

Ronald S. Bultje	0d4d223353	vp9: invert order in l[] intra prediction array. The directional intra predictors either don't care about order (dc, h, dc_left, tm), or they prefer inverted order (vr, dr, hd). This allows more efficient SIMD implementations.	11 years ago
