Got a crash when trying to init encoder on x86 emulator: 04-16 05:49:12.448 20393-20393/?

Try to disable SSE4_1 for x86. Because not all processors support it.

I got SIGILL when running on x86 emulator. My workaround was disabling on x86 SSE4.1 although my CPU has SSE4.1 and 4.2.

Here is the modified part of my Android.mk

ifeq ($(TARGET_ARCH_ABI),x86)
    LOCAL_CFLAGS += \
                    -DOPUS_X86_MAY_HAVE_SSE -DOPUS_X86_PRESUME_SSE \
                    -DOPUS_X86_MAY_HAVE_SSE2 -DOPUS_X86_PRESUME_SSE2 \
                    #-DOPUS_X86_MAY_HAVE_SSE4_1 -DOPUS_X86_PRESUME_SSE4_1 -msse4.2 \
                    -DOPUS_X86_MAY_HAVE_AVX -mavx \
                    -DOPUS_HAVE_RTCD -DCPU_INFO_BY_C
    HAVE_SSE=1
    HAVE_SSE2=1
    #HAVE_SSE4_1=1
endif

ifeq ($(TARGET_ARCH_ABI),x86_64)

could you make a pr with updated *.so libs?

[Rmaan]

There is no *.so file in the repo. Here is compiled library with SSE4.1 disabled for x86. You should remove .zip extension (Github doesn't support .aar extension). You could find .so files inside.

opuscodec.aar.zip
