# Date Author Comment
fe2ff6d2 02/04/2011 02:08 AM Justin Ruggles

Separate format conversion DSP functions from DSPContext.

This will be beneficial for use with the audio conversion API without
requiring it to depend on all of dsputil.

Signed-off-by: Mans Rullgard <>
(cherry picked from commit c73d99e672329c8f2df290736ffc474c360ac4ae)

a35d782d 02/04/2011 02:08 AM Alex Converse

Fix ff_imdct_calc_sse() on gcc-4.6

Gcc 4.6 only preserves the first value when using an array with an "m"
constraint.

Signed-off-by: Mans Rullgard <>
(cherry picked from commit 770c410fbb8e1b87ce8ad7f3d7eddaa55e2b8295)

baffa091 02/02/2011 02:40 AM Ronald S. Bultje

Implement a SIMD version of emulated_edge_mc() for x86.

From ~550 cycles (C version) to 170 (SSE/x86-64), 206 (MMX/x86-32)
and 196 (SSE2/x86-32) cycles.
(cherry picked from commit 81f2a3f4ffcc6935b8b8ada4954700b3f333ae4f)
