FFMPEG iOS 7图书馆 [英] FFMPEG iOS 7 Library

问题描述

我已经尝试阅读了很多教程。
我在google上花了几个小时，stackoverflow尝试回答。
到目前为止，我已经阅读：尝试使用armv6和arv7架构为iPhoneOS平台编译FFMPEG库 在iphone / ipad项目上的FFMPEG集成和 https://github.com / lajos / iFrameExtractor 几个。

我正在为iOS 7 / Xcode 5兼容性构建此库，但它不起作用。
我会得到的一个常见错误是：

 配置为：--prefix = / Applications / Xcode.app / contents / Developer / usr --with-gxx-include-dir = / usr / include / c ++ / 4.2.1 
 yasm / nasm未找到或太旧。使用--disable-yasm作为一个瘫痪的构建。 
 
如果您认为配置错误，请确保您使用Git中最新的
版本。如果最新版本失败，请将问题报告给irc.freenode.net上的
 [e-mail]邮件列表或IRC #ffmpeg。 
包含由configure生成的日志文件config.log，因为这将帮助
解决问题。 
  

我还会得到更多的一次完成。例如：

  rm：非法选项 - 。 
用法：rm [-f | -i] [-dPRrvW]文件... 
取消链接文件
 make：*** [clean]错误64 
  

我大部分尝试使用这个命令来启动，但它总是在make clean上崩溃：

  ./ 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 \ 
 --target-os = darwin \ 
 --arch = arm \ 
 --cpu = cortex-a8 \ 
 --extra-cflags =' -  arch armv7'\ 
 --extra-ldflags =' -  arch armv7 -isysroot / Applications /Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS7.0.sdk'\ 
 --prefix = compiled / armv7 \

 --disable-ffmpeg \ 
 --disable-ffplay \ 
 --disable-ffprobe \ 
 --disable-ffserver \

解决方案

要使用mooncatventures（我们的）ffmpegdecoderFramework，进入构建设置
点击拱门并删除armv7s。

你还必须更改构建img src =https://i.stack.imgur.com/mFowQ.pngalt =enter image description here>

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 architecture FFMPEG integration on iphone/ ipad project and https://github.com/lajos/iFrameExtractor few of the many.

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:

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
[e-mail] 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:

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":

./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 \
--target-os=darwin \
--arch=arm \
--cpu=cortex-a8 \
--extra-cflags='-arch armv7' \
--extra-ldflags='-arch armv7 -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS7.0.sdk' \
--prefix=compiled/armv7 \
--enable-cross-compile \
--enable-nonfree \
--enable-gpl \
--disable-armv5te \
--disable-swscale-alpha \
--disable-doc \
--disable-ffmpeg \
--disable-ffplay \
--disable-ffprobe \
--disable-ffserver \
--disable-asm \
--disable-debug

解决方案

To use the mooncatventures (our) ffmpegdecoderFramework, go into build settings click on the arch and remove the armv7s.

you must also change build active architechure only to no.
