• Compiling x264 on a Mac : "No working C compiler found" and "arm-linux-androideabi-gcc : command not found"

  29 novembre 2014, par Xavi Gil

  I am trying to compile the x264 library for Android, following this post.

  I have cloned the x264 project git clone git://git.videolan.org/x264.git and tried to compile with the following configuration :

  NDK=~/development/android-ndk-r10c    
  
  TOOLCHAIN=$NDK/toolchains/arm-linux-androideabi-4.6/prebuilt/linux-x86_64
  
  PLATFORM=$NDK/platforms/android-21/arch-arm
  
  
  
  ./configure \
  
  --cross-prefix=$TOOLCHAIN/bin/arm-linux-androideabi- \
  
  --sysroot=$PLATFORM \
  
  --host=arm-linux \
  
  --enable-pic \
  
  --enable-static \
  
  --disable-cli

  The problem is that I get a No working C compiler found. error.

  The conftest.log output :

  $ cat conftest.log 
  
  ./configure: line 153: arm-linux-androideabi-gcc: command not found

  But the arm-linux-androideabi-gcc is the toolchain’s bin folder !!

  Looking at this other question it looks like for some reason, even though the file exists, since it is a 64bit Mac, it won’t execute the arm-linux-androideabi-gcc file and will return this weird error and log.

  $ xcode-select -p
  
  /Applications/Xcode.app/Contents/Developer

  $ gcc --version
  
  Configured with: --prefix=/Applications/Xcode.app/Contents/Developer/usr --with-gxx-include-dir=/usr/include/c++/4.2.1

  Can anyone tell me how to fix this please ?

• Combine Two Video using Go - FFmpeg

  11 mai 2017, par JosephCenk

  I have two videos, Video A && Video B. I want to combine both video to a new Video C using golang. I tried FFmpeg but unable to cross compile it for ARM devices and getting error message.
  /usr/local/ffmpeg/lib/libavdevice.so : file not recognized : File format not recognized collect2 : error : ld returned 1 exit status

  Please advise.
  Opening two media player at once is not an option. With amd64 I compile without having any issue.

• FFmpegKit in Flutter fails with configuration output on Android

  15 décembre 2024, par ashvin jadav

  I am using ffmpeg_kit_flutter in my Flutter app to add a text overlay to a video. However, when I try to execute the FFmpeg command, I get an output similar to this :

  


  configuration : --cross-prefix=aarch64-linux-android- --sysroot=/Users/sue/Library/Android/sdk/ndk/22.1.7171670/toolchains/llvm/prebuilt/darwin-x86_64/sysroot --prefix=/Users/sue/Projects/arthenica/ffmpeg-kit/prebuilt/android-arm64/ffmpeg --pkg-config=/opt/homebrew/bin/pkg-config --enable-version3 --arch=aarch64 --cpu=armv8-a --target-os=android --enable-neon --enable-asm --enable-inline-asm --ar=aarch64-linux-android-ar --cc=aarch64-linux-android24-clang --cxx=aarch64-linux-android24-clang++ --ranlib=aarch64-linux-android-ranlib --strip=aarch64-linux-android-strip --nm=aarch64-linux-android-nm --extra-libs='-L/Users/sue/Projects/arthenica/ffmpeg-kit/prebuilt/android-arm64/cpu-features/lib -lndk_compat' --disable-autodetect --enable-cross-compile --enable-pic --enable...

  


  Here is my code :

  


  final command = '-i $_videoPath -vf "drawtext=text=\'Live Score: 10 - 5\':fontcolor=white:fontsize=24:x=10:y=10" $_processedVideoPath';

await FFmpegKit.execute(command).then((session) async {
  final returnCode = await session.getReturnCode();
  final output = await session.getOutput();
  final errorOutput = await session.getFailStackTrace();

  print('Return Code: $returnCode');
  print('Output: $output');
  print('Error Output: $errorOutput');
});
