<div dir="ltr">Hello,<div><br></div><div>I'm having some trouble getting Opus to work in an ARM64 iOS application and I'm wondering if anyone here has any guidance. Maybe I am missing something simple. </div><div><br></div><div>Specifically, the problem is that Opus running on ARM64 outputs different data than other architectures -- ARMv7, ARMv7s, i386, and x86_64. On all other platforms except ARM64, encoding a 1280 byte slice of audio data returns an encoded result of between roughly 50 and 100 bytes. On ARM64, it always returns an encoded result of 1275 bytes.</div><div><br></div><div>Configure arguments:</div><div><br></div><div><div>./configure --disable-shared --enable-static --with-pic --disable-extra-programs --disable-doc --host=arm-apple-darwin --prefix="/Users/cconover/Projects/Opus-iOS/build/built/iPhoneOS8.2-arm64.sdk" LDFLAGS=" -flto -fPIE -miphoneos-version-min=7.0 -L/Users/cconover/Projects/Opus-iOS/dependencies/lib" CFLAGS=" -arch arm64 -Ofast -flto -g -fPIE -miphoneos-version-min=7.0 -I/Users/cconover/Projects/Opus-iOS/dependencies/include -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS8.2.sdk" </div></div><div><br></div><div><div>What's also interesting is that the decoder doesn't seem to have any problem decoding the data on ARM64. It happily decodes it from 1275 back to the original 1280 bytes of audio data.</div><div><br></div><div>Also of note, I'm calling into Opus from C# using PInvokes. Again, it seems to work fine on everything but ARM64.</div><div><br></div><div>Thoughts? I can provide whatever other information is needed.</div><div><br></div>-- <br><div class="gmail_signature"><div dir="ltr"><div><div dir="ltr">Chris Conover<div>Mobile Team Lead/Sports Product Manager, Curse Inc.</div><div>Skype: cconover-skype</div><div>Cell: 954-258-8274</div></div></div></div></div>
