添加播放的第三方库出现的bug
1、添加 ** FFmpeg-iOS-build-script ** 出现的报错信息
I am able to compile ffmpeg library but when integrate static library of ffmpeg its still giving undefined symbol error for various architecture.
I have tried with http://sourceforge.net/projects/ffmpeg-ios/postdownload?source=dlp too but this is giving same error
Undefined symbols for architecture armv7:
"_BZ2_bzDecompressInit", referenced from:
_matroska_decode_buffer in libavformat.a(matroskadec.o)
"_iconv", referenced from:
_avcodec_decode_subtitle2 in libavcodec.a(utils.o)
"_BZ2_bzDecompress", referenced from:
_matroska_decode_buffer in libavformat.a(matroskadec.o)
"_BZ2_bzDecompressEnd", referenced from:

"_iconv_open", referenced from:

"_iconv_close", referenced from:

_avcodec_decode_subtitle2 in libavcodec.a(utils.o)
ld: symbol(s) not found for architecture armv7
clang: error: linker command failed with exit code 1 (use -v to see invocation)
2、添加 MobileVLCKit.framework出现的报错信息

ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
解决方法
1、Targets -> General -->Linked Frameworks and Libraries 中，添加 libbz2.dylib,libiconv.dylib两个文件
2、 添加之后如果出现
**duplicate symbols for architecture x86_64 **
处理方法是：
Targets -> Build Setting -->Other Linker Flags 中，找到，并删除
-ObjC
