[libav-devel] [PATCH 19/19] aarch64: vp8: Optimize vp8_idct_add_neon for aarch64

The previous version was a pretty exact translation of the arm version. This version does do some unnecessary arithemetic (it does more operations on vectors that are only half filled; it does 4 uaddw and 4 sqxtun instead of 2 of each), but it reduces the overhead of packing data together (which

[libav-devel] [PATCH 18/19] aarch64: vp8: Skip saturating in shrn in ff_vp8_idct_add_neon

The original arm version didn't do saturation here. This probably doesn't make any difference for performance, but reduces the differences. --- libavcodec/aarch64/vp8dsp_neon.S | 8 1 file changed, 4 insertions(+), 4 deletions(-) diff --git a/libavcodec/aarch64/vp8dsp_neon.S

[libav-devel] [PATCH 09/19] aarch64: vp8: Move the vp8dsp makefile entries to the right places

Even if NEON would be disabled, the init functions should be built as they are called as long as ARCH_AARCH64 is set. These functions are part of a generic DSP subsytem, not tied directly to one decoder. (They should be built if the vp7 decoder is enabled, even if the vp8 decoder is disabled.)
