1.mov格式解析

2。mov解析的开源工程:bento4和ffmpeg,其中bento4直接有xcode的工程文件,和比较详细的test代码
3。ffmpeg如何解析帧图像,可以看看extracting-frames-from-movies-on-iphone

4。ffmpeg iphone编译

1. 下载:
git clone git://github.com/lajos/iFrameExtractor.git
2. 编辑:
build_armv6和build_armv7,修改./configure后面的参数,主要是SDK版本.我的是4.3,修改为:
./configure --disable-doc --disable-ffmpeg --disable-ffplay --disable-ffserver --enable-cross-compile --arch=arm --target-os=darwin --cc=/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/gcc --as='gas-preprocessor/gas-preprocessor.pl /Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/gcc' --sysroot=/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS4.3.sdk --cpu=arm1176jzf-s --extra-cflags='-arch armv6' --extra-ldflags='-arch armv6'
3. 编译:
出错,提示:
/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/gcc is unable to create an executable file.
C compiler test failed.
Undefined symbols for architecture armv7:
"_BZ2_bzDecompressInit", referenced from:
_matroska_decode_buffer in libavformat.a(matroskadec.o)
"_BZ2_bzDecompressEnd", referenced from:
_matroska_decode_buffer in libavformat.a(matroskadec.o)
"_BZ2_bzDecompress", referenced from:
_matroska_decode_buffer in libavformat.a(matroskadec.o)
添加库libbz2.1.0.dylib,再次编译,OK通过.
7. 修改了ffmpeg版本到最新版(0.7),编译的时候需要把common.mak复制到新版本目录.
编译的时候遇到错误:
ERROR: .endm without .macro at /usr/local/bin/gas-preprocessor.pl line 83, <ASMFILE> line 55
用老版本的libavcodec/arm/asm.S和libavcoec/arm/dsputil_arm.S覆盖新版本(实际上我怀疑只覆盖asm.S即可),重新编译即可.
