Comment (by qyot27):
Building with --disable-yasm = decoding works
Commenting out scalarproduct_float = still silent
Commenting out butterflies_float_interleave = still silent
Commenting out both lines = still silent
Forcing SSE2 by changing line 35 of libavcodec/x86/sbrdsp_init.c from
if (mm_flags & AV_CPU_FLAG_SSE) {
to
if (mm_flags & AV_CPU_FLAG_SSE2) {
makes decoding work, but I don't know if that's the 'ideal' solution here.
