FFMPEG iOS 7库

Question

我试过阅读很多教程.我在google上花了好几个小时,而stackoverflow尝试回答.到目前为止,我已经读过:尝试使用armv6和arv7体系结构 在iphone/ipad项目和https://github.com/lajos/iFrameExtractor中集成一些用于iPhoneOS平台的FFMPEG库.

我正在尝试为iOS 7/Xcode 5兼容性构建此库,但它无法正常工作.我得到的一个常见错误是:

Configured with: --prefix=/Applications/Xcode.app/Contents/Developer/usr --with-gxx-include-dir=/usr/include/c++/4.2.1
yasm/nasm not found or too old. Use --disable-yasm for a crippled build.

If you think configure made a mistake, make sure you are using the latest
version from Git.  If the latest version fails, report the problem to the
ffmpeg-user@ffmpeg.org mailing list or IRC #ffmpeg on irc.freenode.net.
Include the log file "config.log" produced by configure as this will help
solving the problem.

一旦完成,我还会得到更多.如:

rm: illegal option -- .
usage: rm [-f | -i] [-dPRrvW] file ...
       unlink file
make: *** [clean] Error 64

我大多尝试使用此命令启动,但它总是在"make clean"崩溃:

./configure \
--cc=/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/gcc \
--as='/usr/local/bin/gas-preprocessor.pl /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/gcc' \
--sysroot=/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS7.0.sdk \

--extra-ldflags='-arch armv7 -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS7.0.sdk' \

要使用mooncatventures(我们的)ffmpegdecoderFramework,请进入构建设置,单击拱门并移除armv7s.

您还必须将构建活动架构更改为否.
