• Compile ffmpeg with x264 shows : ERROR : libx264 not found in docker building image

  3 mai 2019, par NKam

  Trying to install ffmpeg from source with libx264 package. When I compile ffmpeg can’t find x264 because it is not installed.
  I followed ffmpeg installation guide.

  Before intention to compile ffmpeg in building docker image I tried to install locally and found out in folder ffmpeg_build/include I don’t have x264 files installed.

  To compile libx264 I used :

  cd /ffmpeg_sources &&

  git -C x264 pull 2> /dev/null || git clone —depth 1 https://code.videolan.org/videolan/x264.git &&

  cd x264 &&

  PATH="$HOME/bin :$PATH"

  PKG_CONFIG_PATH="$HOME/ffmpeg_build/lib/pkgconfig" ./configure —prefix="$HOME/ffmpeg_build" —bindir="$HOME/bin" —enable-static —enable-pic &&

  PATH="$HOME/bin :$PATH" make &&

  make install

  I changed url to https://code.videolan.org/videolan/x264.git, because this url https://git.videolan.org/git/x264 from guide not working

  I want to know what I missed. I want ffmpeg to find x264, if it is not installed how can I find way to install.

• ffmpeg main() function in android studio

  21 avril 2016, par Spartan

  Here I am trying to use ffmpeg with gradle experimental plugin.

  This is how I included all my shared libraries and their headers in repositories

  repositories {
  
      libs(PrebuiltLibraries) {
  
          libavdevice {
  
              headers.srcDir "/home/spartan/AndroidStudioProjects/Hello/app/src/main/jni/include"
  
              binaries.withType(SharedLibraryBinary) {
  
                  sharedLibraryFile = file("/home/spartan/AndroidStudioProjects/Hello/app/src/main/jniLibs/${targetPlatform.getName()}/libavdevice-57.so")
  
              }
  
          }
  
  
  
          libavcodec {
  
              headers.srcDir "/home/spartan/AndroidStudioProjects/Hello/app/src/main/jni/include"
  
              binaries.withType(SharedLibraryBinary) {
  
                  sharedLibraryFile = file("/home/spartan/AndroidStudioProjects/Hello/app/src/main/jniLibs/${targetPlatform.getName()}/libavcodec-57.so")
  
              }
  
          }
  
  
  
          libavutil {
  
              headers.srcDir "/home/spartan/AndroidStudioProjects/Hello/app/src/main/jni/include"
  
              binaries.withType(SharedLibraryBinary) {
  
                  sharedLibraryFile = file("/home/spartan/AndroidStudioProjects/Hello/app/src/main/jniLibs/${targetPlatform.getName()}/libavutil-55.so")
  
              }
  
          }
  
  
  
          libavformat {
  
              headers.srcDir "/home/spartan/AndroidStudioProjects/Hello/app/src/main/jni/include"
  
              binaries.withType(SharedLibraryBinary) {
  
                  sharedLibraryFile = file("/home/spartan/AndroidStudioProjects/Hello/app/src/main/jniLibs/${targetPlatform.getName()}/libavformat-57.so")
  
              }
  
          }
  
  
  
          libswscale {
  
              headers.srcDir "/home/spartan/AndroidStudioProjects/Hello/app/src/main/jni/include"
  
              binaries.withType(SharedLibraryBinary) {
  
                  sharedLibraryFile = file("/home/spartan/AndroidStudioProjects/Hello/app/src/main/jniLibs/${targetPlatform.getName()}/libswscale-4.so")
  
              }
  
          }
  
  
  
          libswresample {
  
              headers.srcDir "/home/spartan/AndroidStudioProjects/Hello/app/src/main/jni/include"
  
              binaries.withType(SharedLibraryBinary) {
  
                  sharedLibraryFile = file("/home/spartan/AndroidStudioProjects/Hello/app/src/main/jniLibs/${targetPlatform.getName()}/libswresample-2.so")
  
              }
  
          }
  
  
  
  
  
  
  
      }
  
  }
  
  
  
  android.ndk {    
  
          moduleName = "video_trim"
  
          ldLibs.addAll(["log", "android","jnigraphics"])
  
      }
  
  
  
  
  
      android.sources {
  
          main {
  
              jni {
  
                  dependencies {
  
                     library "libavdevice" linkage "shared"
  
                     library "libavcodec" linkage "shared"
  
                     library "libavutil" linkage "shared"
  
                     library "libavformat" linkage "shared"
  
                     library "libswscale" linkage "shared"
  
                     library "libswresample" linkage "shared" 
  
  
  
                  }
  
              }
  
          }
  
      }

  I tested one ffmpeg function(without using main function) which is running successfully. So this configuration seems ok.

  No I want to use ffmpeg.c’smain() function to use cmd for that I manually copy pasted ffmpeg.c,cmdutils.c, cmdutils.h, ffmpeg_filter.c, ffmpeg_opt.c,ffmpeg.h in my jni folder along with video_trim.c.( I took refrence from halfninja ).

  Here I am not using Andoid.mk so instead of LOCAL_C_INCLUDES, tried like this(updated android.ndk) to include ffmpeg folder(cppFlags was not working so I used CFlags also) :

  android.ndk {  
  
          moduleName = "video_trim"
  
  
  
          cppFlags.add("-I/home/spartan/ndk/android-ndk-r11c/sources/ffmpeg-3.0.1")
  
          CFlags.add("-I/home/spartan/ndk/android-ndk-r11c/sources/ffmpeg-3.0.1")
  
  
  
          ldLibs.addAll(["log", "android","jnigraphics"])
  
      }

  But I am getting lot of undefined reference to error.
  Ex :

  /home/spartan/AndroidStudioProjects/Hello/app/src/main/none/cmdutils.c
  
  Error:(1086) undefined reference to 'avfilter_version'
  
  Error:(1086) undefined reference to 'avfilter_configuration'
  
  Error:(1621) undefined reference to 'avfilter_pad_get_type'
  
  Error:(1618) undefined reference to 'avfilter_pad_get_name'
  
  Error:(1610) undefined reference to 'avfilter_next'
  
  Error:(1815) undefined reference to 'avfilter_get_by_name'
  
  Error:(1834) undefined reference to 'avfilter_pad_count'

  9 avril 2017, par sdgm

  I was looking for a c++-Instagram API but there was not any complete project. Now,I am using python-Instagram API. whenever I execute my code, too many errors occur. this is my code :

  from InstagramAPI import InstagramAPI
  
  
  
  InstagramAPI = InstagramAPI("no_ideaw", "xs*************#")
  
  InstagramAPI.login()
  
  InstagramAPI.removeProfilePicture()

  Then, these are the errors :

  I tried to install
