I compiled FFMPEG libs which supports for iOS 7 and 8 but since recent release with iOS 9 there is a new feature has issued which called bitcode mode , as a default setting , this setting has set to NO .
But if i set this as yes , following error will execute ,
libavdevice.a(avfoundation.o)' does not contain bitcode. You must rebuild it with bitcode enabled (Xcode setting ENABLE_BITCODE), obtain an updated library from the vendor, or disable bitcode for this target. for architecture arm64
Is there any way to compile FFMPEG which supports FFMpeg in bitcode enabled mode
here is the build script i used
