大家好, 小弟最近想要用ffmpeg 在iPhone上解H264的frame, compile上没有问题, 但是要放上iPhone run的时候, debugger会出现: dyld: Library not loaded: /usr/local/lib/libavcodec.dylib Referenced from: /var/mobile/Applications/66E93E8A-AA25-4D9A-B69F-F4F040D84E17/xxxx.app/xxxx Reason: image not found 奇怪就奇怪在, 为什麽是dyld... 小弟明明就是用static lib... 以下是有关小弟的ffmp的compile资讯 1. ffmpeg目录放在iPhone xxxx project目录下的ffmpeg 2. configure如下: (为方便阅读, 每个参数断一行) ./configure --enable-gpl --enable-pthreads --disable-encoders --disable-decoders --enable-decoder=h264 --disable-parsers --enable-parser=h264 --disable-protocols --enable-zlib --disable-muxers --disable-demuxers --disable-yasm --enable-shared --disable-doc --disable-ffmpeg --disable-ffplay --disable-ffserver --disable-amd3dnow --disable-amd3dnowext --disable-mmx --disable-mmx2 --disable-sse --disable-ssse3 --disable-neon --disable-vis --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/iPhoneOS4.1.sdk --cpu=cortex-a8 --extra-cflags='-arch armv7' --extra-ldflags='-arch armv7' --enable-pic 以上设定关於系统的部份是参考: http://tinyurl.com/yyptqgd build完後会将 lib*.a copy到 xxxx/ffmpeg/lib/ 3. project target 内的Build设定 (最後放在device上是用armv7) Architectures: Standar(armv6 armv7) Base SDK: iOS Device4.1 Build Active Architecture Only: 没打勾 Valid Architectures: armv6 armv7 Header Search Paths: ./ffmpeg Library Search Paths: $(inherited) "$(SRCROOT)" "$(SRCROOT)/ffmpeg" "$(SRCROOT)/ffmpeg/libavcodec" "$(SRCROOT)/ffmpeg/libavdevice" "$(SRCROOT)/ffmpeg/libavformat" "$(SRCROOT)/ffmpeg/libavutil" "$(SRCROOT)/ffmpeg/libswscale" "$(SRCROOT)/ffmpeg/lib" 以上, 麻烦各位高手指点~ --
