FFMPEG Binary in OSX Package

Hiiiiii All,
Spent my last working day to solve issue related to packaging of FFMPEG binary in OSX release build.Every time i made a package its build correctly but the moment when FFMPEG binary is invoked i get error :

CMSampleBufferGetImageBuffer signalled err=-12731(kCMSampleBufferError_RequiredParameterMissing)

So the way to avoid this error we have to do following steps :

• Project Settings

• Click Target

• Click Capabilities

• Enable App-Sandbox

• A file is added in project named Target.entitlements

Inside Entitlements file add following info :

• com.apple.security.inherit [Boolean] YES

• App Sandbox [Boolean] YES

Also add a RunScript in Target's Build Phase:

codesign -f -s "your certificate" 

--entitlements ./ffmpeg.entitlements 

./Build/Intermediates/ArchiveIntermediates/App\ Store/InstallationBuildProductsLocation/Applications/<my app>/Contents/MacOS/ffmpeg

Hope it hepls :)
