I have a broken version of the script to build FLAC library.

Need help!

Thanks! I could build ffmpeg 2.1.1 with your script.
http://stackoverflow.com/a/20064462/827310

This script is working for all ffmpeg versions since 1.0.

is there any possibility that ffmpeg before 1.0 can be compiled by xcode5?
Have you ever try that?
thanks!!!

Thanks! But when I compile ffmpeg2.1.1 use your script ,I still encounter the problem "Unable to identify target architecture at /usr/bin/gas-preprocessor.pl line 82" .
I used iPhoneOS7.0.sdk .
I don't where is wrong .Thanks again.

i had to change line 56: tar zxf ffmpeg-${VERSION}.tar.bz2 -C $SRCDIR to
tar jxf ffmpeg-${VERSION}.tar.bz2 -C $SRCDIR

the z option is for gzip archives and the script downloads bzip2 archive. tar failed every time unless I changed the "z" to "j". now it works fine

On my building environment XCode5/ios7, the "--cross-prefix="${DEVELOPER}/Toolchains/XcodeDefault.xctoolchain/usr/bin/" MUST be added to the configure script, if not the ranlib should be failed when compile armv7/armv7s.

@wumingyun No i didn't. I built only >1.0.
@d370urn3ur Thanks, i will fix it.

Thnx for the script! It saved me a lot of time. Can you also make it compile for x86_64? I want to use ffmpeg on Mac app and i've tried changing the arch to x86_64 but for some reason the library is not working as intended...

wonderful! I just need to use ffmpeg

Thanks very much. This is very useful for me.

This is awesome. Thank you!

Thanks so much. I love you.

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

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!
