• Compiling FFMPEG with x265 has ERROR : x265 not found using pkg-config

  23 mars 2023, par timweiliu

  At first, I have a project with ffmpeg build support x264 for android in Mac OS.

  



  Now, I want to add x265 support.

  



  I have compiled the x265 with make & make install like this :

  



  [ 81%] Built target x265-static
[100%] Built target cli
Install the project...
-- Install configuration: "Release"
-- Up-to-date: /usr/local/lib/libx265.a
-- Up-to-date: /usr/local/include/x265.h
-- Up-to-date: /usr/local/include/x265_config.h
-- Up-to-date: /usr/local/lib/pkgconfig/x265.pc
-- Up-to-date: /usr/local/bin/x265


  



  and then, I run this shell script :

  



  make distclean 

NDK_PATH=$NDK_HOME
NDK_ARM_PATH=${NDK_PATH}/platforms/android-9/arch-arm
NDK_ARM_BIN_PATH=${NDK_PATH}/toolchains/arm-linux-androideabi-4.9/prebuilt/darwin-x86_64/bin

CC=${NDK_ARM_BIN_PATH}/arm-linux-androideabi-gcc

chmod +x configure
chmod +x version.sh

if [ $APP_ABI = "armeabi-v7a" ]; then
LOCAL_CFLAGS="-O3 -DANDROID -fpic -I/usr/local/include -march=armv7-a -mfloat-abi=softfp -mfpu=neon"
ABLES="--enable-asm --enable-thumb --enable-hwaccels --cpu=armv7-a --enable-neon"
elif [ $APP_ABI = "armeabi" ]; then
LOCAL_CFLAGS="-O3 -DANDROID -fpic -I/usr/local/include"
ABLES="--disable-neon"
fi
echo $LOCAL_CFLAGS
echo $ABLES
echo $PKG_CONFIG_PATH

echo "开始configure"
./configure \
--disable-yasm \
--disable-debug \
--disable-doc \
--disable-ffmpeg \
--disable-ffprobe \

--disable-encoders \
--enable-encoder=libx264 \
--enable-encoder=libfdk_aac \
--enable-libx265 \
--pkg-config-flags="--static" \
...

echo "开始make"
make -j4

echo "开始install"
sudo make install


  



  It results in an error :

  



  -O3 -DANDROID -fpic -I/usr/local/include -march=armv7-a -mfloat-abi=softfp -mfpu=neon
--enable-asm --enable-thumb --enable-hwaccels --cpu=armv7-a --enable-neon
/usr/local/lib/pkgconfig
开始configure
ERROR: x265 not found using pkg-config


  



  I looked at the config.log :

  



  use_pkg_config x265 x265.h x265_api_get
check_pkg_config x265 x265.h x265_api_get
false --exists --print-errors x265
ERROR: x265 not found using pkg-config


  



  but, the file of x265.pc is existing on the path. Its content is :

  



  prefix=/usr/local
exec_prefix=${prefix}
libdir=${exec_prefix}/lib
includedir=${prefix}/include

Name: x265
Description: H.265/HEVC video encoder
Version: 0.0
Libs: -L${libdir} -lx265
Libs.private: -lstdc++ -lm -lgcc -ldl -lgcc -ldl
Cflags: -I${includedir}


  



  and the x265.h is in include path too.

  



  I run

  



  pkg-config --list-all


  



  It also finds x265 :

  



  TIMWEILIU-MC0:libSrc timweiliu$ pkg-config --list-all
libecpg_compat libecpg_compat - PostgreSQL libecpg_compat library
fdk-aac        Fraunhofer FDK AAC Codec Library - AAC codec library

libpcreposix   libpcreposix - PCREPosix - Posix compatible interface to libpcre
libiodbc       iODBC - iODBC Driver Manager


  



  Now, I don’t know why it does not work.
Why does pkg-config still not find the x265 ?

  


• I can't use immediately converted video with FFmpeg (Android)

  26 juin 2019, par Jose Q

  I’m using this lib to turn a video with a watermark into a corner : https://github.com/WritingMinds/ffmpeg-android-java

  To detect when the video conversion is ready I’m using this :

  try {
  
          ffmpeg.execute(command, new ExecuteBinaryResponseHandler() {
  
              @Override
  
              public void onFailure(String s) {
  
              }
  
  
  
              @Override
  
              public void onSuccess(String s) {
  
              }
  
  
  
              @Override
  
              public void onProgress(String s) {
  
              }
  
  
  
              @Override
  
              public void onStart() {
  
              }
  
  
  
              @Override
  
              public void onFinish() {
  
  
  
                  //outpath is: /storage/emulated/0/drawable/share1561561063811.mp4
  
                  Uri u = Uri.parse(outpath);
  
  
  
              }
  
          });
  
      } catch (FFmpegCommandAlreadyRunningException e) {
  
          // do nothing for now
  
      }

  Well, everything goes perfect so far, I can find the video through the file manager, but what I can’t do is use it immediately after onFinish() in my app.

  I can’t play the video or upload it. I’ve tried using outpath directly and also tried this method that works for other videos and I get null. :

  private String getRealPathFromURI(Uri contentUri) {
  
      String[] proj = { MediaStore.Images.Media.DATA };
  
      CursorLoader loader = new CursorLoader(this, contentUri, proj, null, null, null);
  
      Cursor cursor = loader.loadInBackground();
  
      int column_index = cursor.getColumnIndexOrThrow(MediaStore.Video.Media.DATA);
  
      cursor.moveToFirst();
  
      String result = cursor.getString(column_index);
  
      cursor.close();
  
      return result;
  
  }

• Video Processing in background using ffmpeg

  20 juin 2019, par Mehran

  The problem comes when during the video processing user closes the application himself from the task manager then its processing stops.

  I am working on video file processing in android using FFMpeg, which is working perfectly but when I do close the application during processing from task manager then video processing has stopped working even I added all the work in work manager.

  @Override
  
  public Result doWork() {
  
      shellCommand = new ShellCommand();
  
      ffmpegBinary = new String[] {
  
          FileUtils.getFFmpeg(context).getAbsolutePath()
  
      };
  
      command = concatenate(ffmpegBinary, command);
  
      CommandResult commandResult = getCommandResult(command);
  
      if (command`enter code here`Result.success) {
  
          onSuccess(videoPath);
  
      } else {
  
          onFailure(videoPath);
  
      }
  
  }
  
  //getCommandResult
  
  private CommandResult getCommandResult(String[] command) {
  
      try {
  
          process = shellCommand.run(command, null);
  
  
  
          if (process == null) {
  
              return CommandResult.getDummyFailureResponse();
  
          }
  
          checkAndUpdateProcess();
  
          return CommandResult.getOutputFromProcess(process);
  
      } catch(Exception e) {} finally {
  
          Util.destroyProcess(process);
  
      }`enter code here`
  
      return CommandResult.getDummyFailureResponse();
  
  }

  As far as I can tell, when the application closes from the background then the parent process destroys it and is destroying all of its sub-process too, FFMpeg is using the android process to execute the command and check the video file status during video processing.
