• Yet another ffmpeg/libx264 issue

  26 décembre 2013, par kerim yucel

  My current situation is ; ffmpeg and libx264 has been compiled for Android, as shared and static libraries respectively. Since I have libx264.a and libffmpeg.so with me, only thing that remains is to link them and obtain a ffmpeg library that would allow me to proceed with my application. However, some questions remain unanswered. I am using Ubuntu with a virtual machine under Windows 7. I am using x264's last version, ffmpeg 0.10.4 release and NDK 7.

  I have tried to adjust flags (extracf and extrald) in order to include libx264 to ffmpeg compilation process as well, however I keep failing. Below you may find my build script for ffmpeg and the errors I have encountered.

  NDK=~/Android_NDK_r7b

  If I basically delete the lines extracf and extrald flags and use other ones (commented outs), it works fine except libx264 not found error. Otherwise, I get the following erros.

  ./buildnew.sh: line 35: --extra-cflags=-I/usr/local/include: No such file or directory 
  
  ./buildnew.sh: line 38: --extra-ldflags=-L/usr/local/lib: No such file or directory 
  
  ./buildnew.sh: line 40: --disable-everything: command not found 
  
  ./buildnew.sh: line 44: --enable-gpl: command not found 

  The compilation process ends with the following.

  make: *** [libavdevice/v4l.o] Error 1 
  
  make: *** Waiting for unfinished jobs.... 
  
  /home/mehmet/Android_NDK_r7b/toolchains/arm-linux-androideabi-4.4.3/prebuilt/linux-x86/bin/arm-linux-androideabi-ar: creating libavcodec/libavcodec.a 
  
  /home/mehmet/Android_NDK_r7b/toolchains/arm-linux-androideabi-4.4.3/prebuilt/linux-x86/bin/arm-linux-androideabi-ld: cannot open output file ./androidIncludeTrialsNDK7/armv7-a/libffmpeg.so: No such file or directory 

  I have x264 installed in my directory /home/mehmet/x264 and I also check whereis x264.a, it shows me as /usr/local/lib. I have tried changing the path $x264 to point out to home/mehmet/x264 folder, but I get the same error.

  Lastly, if I enable both extracf and extrald flags ( both commented ones and the used ones) . I get the same error mentioned above. I am afraid I am doing a simple typo here, but can`t see it and it is driving me crazy. Thanks a lot for your help.

  Best.

  EDIT

  I have deleted the comments and now obtain the following.

  ./buildnew.sh: 4: ./buildnew.sh: function: not found
  
  ERROR: libx264 not found

  Above error is observed from the terminal when I run the script. It build upto some point and finishes the process with the following error.
