Thanks! But when I compile ffmpeg2.2.2 use your script ,I still encounter the problem "Unable to identify target architecture at /usr/bin/gas-preprocessor.pl line 82" .
I used iPhoneOS7.1.sdk .
I don't where is wrong .Thanks again.

help me

the libavcodec.a is large than 133.6MB , how can I make a small libavcodec.a

/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/ranlib: archive member: libavformat/libavformat.a(w64.o) cputype (12) does not match previous archive members cputype (7) (all members must match)
make: *** [libavformat/libavformat.a] Error 1

i do not know why？I use xcode 6.

Update for xcode 6.1 with ios 8 ver above. Recommended changes to the script ?
Moreover in the path I${DEVELOPER}/Platforms/${PLATFORM}.platform/Developer/SDKs/${PLATFORM}${SDKVERSION}.sdk/usr/lib - only 5.0sdk is avaialble even though i user xcode 6.1 with ios 8.0. Is sdks path changed , any changes in script? Thanks!
