• Trying to compile the FFMPEG libraries for iPhoneOS platform with armv6 and arv7 architecture

  9 octobre 2013, par Er Amit Sachdeva

  I'm trying to compile the FFMPEG Libraries for IOS platform with arm7 architecture. I downloaded the FFMPEG libraries from http://www.ffmpeg.org.

  I'm successfully able to build the static libraries for the i386 architecture for the iPhoneSimulator. But I need the libraries for iPhoneOS. Using the configure command I'm getting an error. Below are my command details.

  For i386(which is error free) :

  ./configure  --enable-cross-compile --disable-debug --disable-ffmpeg --disable-ffplay --disable-ffprobe --disable-ffserver --disable-doc --disable-network  --disable-everything  --enable-protocol=file --enable-demuxer=mov  --enable-muxer=mpegts --enable-bsf=h264_mp4toannexb   --arch=i386 --target-os=darwin --cc=/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/usr/bin/gcc --as='./gas-preprocessor/gas-preprocessor.pl /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/gcc' --sysroot=/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneOS6.1.sdk --cpu=i386 --extra-cflags='-arch i386' --extra-ldflags='-arch i386 -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator6.1.sdk' --prefix="/Users/amit/Desktop/LivuLib-master/LivuLIb/ffmpeg/bin/newLib"

  For armv7 :

  ./configure  --enable-cross-compile --disable-debug --disable-ffmpeg --disable-ffplay --disable-ffprobe --disable-ffserver --disable-doc --disable-network  --disable-everything  --enable-protocol=file --enable-demuxer=mov  --enable-muxer=mpegts --enable-bsf=h264_mp4toannexb   --arch=armv7 --target-os=darwin --cc=/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/gcc --as='./gas-preprocessor/gas-preprocessor.pl /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/gcc' --sysroot=/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS6.1.sdk --cpu=cortex-a9 --extra-cflags='-arch armv7' --extra-ldflags='-arch armv7 -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS6.1.sdk' --prefix="/Users/amit/Desktop/LivuLib-master/LivuLIb/ffmpeg/bin/newLib"

  For above command for Arm7 I'm getting this error :

  /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/gcc is unable to create an executable file.
  
  C compiler test failed.
  
  
  
  If you think configure made a mistake, make sure you are using the latest
  
  version from SVN.

  So please suggest me a possible solution. Why is it not working ? Or do I need to update anything. Thanks.

• How to integrate ffmpeg with gltransition ?

  20 février 2019, par Developer

  I want to build FFMPEG with GLTransition filter. I followed the build instructions from this link

  I also installed all the dependencies for FFMPEG build(GLU & GLEW libs) and configured it with EGL.

  My configured command is :

  ./configure --extra-libs='-lGLEW -lEGL' --enable-filter=gltransition --disable-x86asm

  After executing this command in Enabled Filter log GLTransition filter is there.
  I have checked for GLTransition filter using command :

  ./ffmpeg -v 0 -filters | grep gltransition  

  but it shows nothing.

  Then also cross checked using ffmpeg command below :

  ./ffmpeg -i media/0.mp4 -i media/1.mp4 -filter_complex gltransition -y out.mp4

  but it shows error like,

  [AVFilterGraph @ 0x1febe80] No such filter: 'gltransition'
  
  Error initializing complex filters.
  
  Invalid argument.

  Am I missed something ?

  Unknown option "i386".
  
  See ./configure --help for available options.

  Why Unknown option "i386". ?
