title: Cocoa app with ffmpeg dylibs crashes on Mac OSX 10.5 (but not 10.6 or 10.7)
body: <p>I've built a Cocoa project in Xcode that integrates the ffmpeg dylibs. It runs fine on Mac OSX 10.6 and 10.7 but it crashes on 10.5. I'm compiling on 10.6. Any suggestions? Thanks!</p>
  
  <p>Here's how I've compiled it:</p>
  
  <blockquote>
    <p>./configure --disable-static --enable-shared --disable-outdev=sdl
    --enable-runtime-cpudetect --disable-bzlib --disable-libfreetype --disable-libopenjpeg --enable-zlib --arch=x86_64 --sysroot=/Developer/SDKs/MacOSX10.6.sdk --extra-cflags="-isysroot /Developer/SDKs/MacOSX10.6.sdk -DMACOSX_DEPLOYMENT_TARGET=10.5
    -mmacosx-version-min=10.5"</p>
