• avcodec/hap : add "compressor" option to Hap encoder to disable secondary compression

  avcodec/hap : add "compressor" option to Hap encoder to disable secondary compression
  The secondary compression in Hap is optional, this change exposes that option to
  
  the user as some use-cases favour higher bitrate files to reduce workload
  
  decoding.
  
  Adds "none" or "snappy" as options for "compressor". Selecting "none" disregards
  
  "chunks" option : chunking is only of benefit decompressing Snappy.

• Error : "libavformat\avformat.h : No such file or directory"

  21 février 2023, par Abdo Daood

  I create a simple c++ file called test.cpp :

  


  #include <iostream>&#xA;#include &#xA;using namespace std;&#xA;&#xA;int main() &#xA;{&#xA;    cout &lt;&lt; "Hello, World!";&#xA;    return 0;&#xA;}&#xA;</iostream>

  


  and using g++ in terminal to compile test.cpp file with the command :

  


  g++ test.cpp -o test


  


  I get this error :

  


  test.cpp:2:10: fatal error: libavformat\avformat.h: No such file or directory
    2 | #include 
      |          ^~~~~~~~~~~~~~~~~~~~~~~~
compilation terminated.


  


  Notes :
libavformat\avformat.h path is : /usr/include/x86_64-linux-gnu/libavformat/avformat.h

  


  and using ffmpeg version is :

• libavcodec/avcodec.h : No such file or directory(ffmpeg with android studio)

  14 avril 2016, par Spartan

  I extracted ffmpeg in ndk’s source folder then compiled it there only for that I followed this :http://www.roman10.net/2013/08/18/how-to-build-ffmpeg-with-ndk-r9/ and successfully generated android folder with arm/lib and arm/include files.

  After that I created one Android.mk file in $NDK/sources/ffmpeg/android/arm and one Android.mk in my android project(src/main/jni folder).

  My src/main/jni/Android.mk is like this :

  LOCAL_PATH := $(call my-dir)
  
  
  
  include $(CLEAR_VARS)
  
  
  
  LOCAL_MODULE    := tutorial01
  
  LOCAL_SRC_FILES := tutorial01.c
  
  LOCAL_LDLIBS := -llog -ljnigraphics -lz
  
  LOCAL_SHARED_LIBRARIES := libavcodec
  
  
  
  include $(BUILD_SHARED_LIBRARY)
  
  $(call import-module,ffmpeg-3.0.1/android/arm)

  and $NDK/sources/ffmpeg/android/arm/Android.mk is :

  LOCAL_PATH:= $(call my-dir)
  
  
  
  include $(CLEAR_VARS)
  
  LOCAL_MODULE:= libavcodec
  
  LOCAL_SRC_FILES:= lib/libavcodec-57.so
  
  LOCAL_EXPORT_C_INCLUDES := $(LOCAL_PATH)/include
  
  include $(PREBUILT_SHARED_LIBRARY)

  I updated my build.gradle like this and successfully generated jniLibs with .so files but I am getting libavcodec/avcodec.h : No such file or directory while building project.

  import org.apache.tools.ant.taskdefs.condition.Os
  
  
  
  apply plugin: 'com.android.model.application'
  
  
  
  model {
  
      android {
  
          compileSdkVersion = 23
  
          buildToolsVersion = "23.0.2"
  
  
  
          defaultConfig.with {
  
              applicationId = "com.example.spartan.hello"
  
              minSdkVersion.apiLevel = 18
  
              targetSdkVersion.apiLevel = 23
  
              versionCode = 1
  
              versionName = "1.0"
  
          }
  
      }
  
      android.buildTypes {
  
          release {
  
              minifyEnabled = false
  
              proguardFiles.add(file('proguard-android.txt'))
  
          }
  
      }
  
  
  
      android.sources {
  
          main {
  
              jni {
  
                  source {
  
                      srcDirs = []
  
                  }
  
  
  
              }
  
  
  
          }
  
  
  
          main {
  
              jniLibs {
  
                  source {
  
                      srcDirs = ['src/main/libs']
  
                  }
  
              }
  
          }
  
  
  
      }
  
  
  
      android.ndk {
  
          moduleName = "tutorial01"
  
          stl = 'gnustl_shared'
  
      }
  
  }
  
  
  
  
  
  task ndkBuild(type: Exec) {
  
      if (Os.isFamily(Os.FAMILY_WINDOWS)) {
  
          commandLine 'ndk-build.cmd', '-C', file('src/main').absolutePath
  
      } else {
  
          commandLine 'ndk-build', '-C', file('src/main').absolutePath
  
      }
  
  }
  
  tasks.withType(JavaCompile) {
  
      compileTask -> compileTask.dependsOn ndkBuild
  
  }
  
  
  
  dependencies {
  
      compile fileTree(include: ['*.jar'], dir: 'libs')
  
      testCompile 'junit:junit:4.12'
  
      compile 'com.android.support:appcompat-v7:23.2.1'
  
  }

  and loading them in my activity like this :

  static {
  
          System.loadLibrary("tutorial01");     
  
          System.loadLibrary("avcodec-57");   
  
      }

  This is the output I am getting(you can see on left side .so files are generated and header error in the right side of the image).
  

  I am new to NDK so, Is it ok if we manually paste header files in jni folder ?
