• fatal error : libavcodec/avcodec.h : No such file or directory

  18 février 2014, par Piterwilson

  

  The tooltip is over the line

  #include <libavcodec></libavcodec>avcodec.h>

  I'm new to JNI development. After managing to compile FFMPEG i fail to be able to use it on a project.

  On the screenshot you can see that the folder with the libs and includes is referenced under includes (via Project/properties/C/C++ general/paths and symbols)

  To me it looks like it should find it but i get the error.

  What extra place do i have to specify this folder for the build to work ?

  Edit : contents of Android.mk

  LOCAL_PATH := $(call my-dir)
  
  
  
  include $(CLEAR_VARS)
  
  
  
  LOCAL_MODULE    := FFMpegTest
  
  LOCAL_SRC_FILES := FFMpegTest.cpp
  
  LOCAL_LDLIBS := -llog
  
  
  
  LOCAL_SHARED_LIBRARIES := libavformat libavcodec libswscale libavutil
  
  
  
  include $(BUILD_SHARED_LIBRARY)
  
  include $(call all-subdir-makefiles)

  Thanks

• Error while build ffmpeg for iOS

  30 avril 2014, par AntonD

  I’m trying to build fmmpeg for iOS with the following config :

  ./configure --prefix=build/armv7 --disable-ffmpeg --disable-ffplay --disable-ffprobe --disable-ffserver --enable-avutil --enable-avresample --enable-cross-compile --sysroot="/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS7.0.sdk" --target-os=darwin --cc=gcc  --extra-cflags="-arch armv7 -mfpu=neon -miphoneos-version-min=6.0" --extra-ldflags="-arch armv7 -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS7.0.sdk -miphoneos-version-min=6.0" --arch=arm --cpu=cortex-a9 --enable-pic

  when i try to make it i’m receiving the follow error :

• Compile FFMpeg for Xcode 5 without GCC ?

  9 janvier 2014, par Joseph Toronto

  I'm trying to compile FFMpeg to add to my iOS app project in Xcode5, however since GCC is no longer included the ./configure script included with FFMpeg doesn't work. Unix/Linux is NOT my strong suit so I'm pretty much at a loss as to what to do next. I know I can install GCC manually, but if FFMpeg is compiled with GCC and the rest of my project is compiled with LLVC/Clang/whatever won't it cause problems. I did manage to install FFmpeg with Brew but I'm not sure what that even accomplished since it wasn't done using options flags like below :

  ./configure --prefix=armv7 --disable-ffmpeg --disable-ffplay --disable-ffprobe --disable-ffserver --enable-avresample --enable-cross-compile --sysroot="/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS7.0.sdk" --target-os=darwin --cc="/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/gcc" --extra-cflags="-arch armv7 -mfpu=neon -miphoneos-version-min=6.1" --extra-ldflags="-arch armv7 -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS7.0.sdk -miphoneos-version-min=6.1" --arch=arm --cpu=cortex-a9 --enable-pic

  None of the scripts/fixes I've tried work, even if they're advertised as working in IOS7/Xcode 5, because they all use GCC. What should I do ?
