FFMPEG iOS 7 Library
提问by Destiny Dawn
I've tried reading many tutorials. I've spent hours on google, and stackoverflow trying answer. So far I've read: Trying to compile the FFMPEG libraries for iPhoneOS platform with armv6 and arv7 architectureFFMPEG integration on iphone/ ipad projectand https://github.com/lajos/iFrameExtractorfew of the many.
我试过阅读很多教程。我在谷歌上花了几个小时，在 stackoverflow 上尝试回答。到目前为止，我已阅读：尝试为 iPhoneOS 平台编译 FFMPEG 库，在 iphone/ipad 项目和https://github.com/lajos/iFrameExtractor 中使用 armv6 和 arv7 架构FFMPEG 集成。
I'm trying to build this library for iOS 7/Xcode 5 compatibility but it's not working. A common error I'd get is:
我正在尝试为 iOS 7/Xcode 5 兼容性构建这个库，但它不起作用。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
[email protected] 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.
I'd also get many more once that is finished. Such as:
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
I've mostly tried using this command to start, but it always crashes on "make clean":
我主要尝试使用此命令启动，但它总是在“make clean”时崩溃：

To use the mooncatventures (our) ffmpegdecoderFramework, go into build settings click on the arch and remove the armv7s.
要使用 Mooncatventures（我们的）ffmpegdecoderFramework，请进入构建设置，单击 arch 并删除 armv7s。
you must also change build active architechure only to no.
您还必须仅将构建活动架构更改为否。

Support universal ffmpeg library for iOS7 and XCode5:
Install gas-preprocessor
Click on the ZIP icon to download https://github.com/mansr/gas-preprocessor. Copy gas-preprocessor.pl to /usr/bin directory. Change permission of gas-preprocessor.pl by setting the privilege to Read & Write for all.
Download my shell script from: https://gist.github.com/m1entus/6983547
Run sh build-ffmpeg.sh.
支持 iOS7 和 XCode5 的通用 ffmpeg 库：
安装气体预处理器
点击 ZIP 图标下载 https://github.com/mansr/gas-preprocessor。将 gas-preprocessor.pl 复制到 /usr/bin 目录。通过为所有人设置读写权限来更改 gas-preprocessor.pl 的权限。
从以下位置下载我的 shell 脚本：https: //gist.github.com/m1entus/6983547
运行 sh build-ffmpeg.sh。
