• Android App Bundle build error : File 'root/lib/x86/ffmpeg' uses directory name 'lib'

  7 septembre 2020, par Patel Pinkal

  I have used FFmpeg Android in the project from this repo FFmpeg-Android-Java and implement only the FFmpegAndroid module in the project.

  


  FFmpeg library is working fine when we run directly from Android Studio or we make APK file (debug or Signed).

  


  But When I try to generate the app bundle from Android studio I get the below error.

  


  Execution failed for task ':app:packageReleaseBundle'.
> A failure occurred while executing com.android.build.gradle.internal.tasks.Workers$ActionFacade
  > File 'root/lib/x86/ffmpeg' uses reserved file or directory name 'lib'.

• Rendering video by ffmpeg.wasm in browser occured an error

  15 septembre 2022, par James Bor

  When a local video renderer uses the ffmpeg.wasm library in the Chrome browser, very often an error with the SBOX_FATAL_MEMORY_EXCEEDED code occurs during the rendering process. The standard command set is used. The code below is half fake because it is very long, but describes an approximate action algorithm. Computer performance and RAM capacity do not affect the video, files used - minimal size. Has anyone experienced this and how can we solve it ?
Error screen

  


  const videoGenerate = async (project) => {
  const ffmpeg = createFFmpeg({
      corePath: 'ffmpeg/ffmpeg-core.js',
      workerPath: 'ffmpeg/ffmpeg-core.worker.js'
  });
  await loadFfmpeg(ffmpeg);
  project.projectName = "Default";
  project.fileType = "video/mp4";

  const resultVideo = {
    title: `${project.projectName}ConcatenatedVideo.mp4`,
  };
  // *For fetchFile method and ffmpeg.FS('writeFile', title, file);
  await uploadObjects(project.projectName, ffmpeg);
  // *
  const command = ['-i', project.video, resultVideo.title];
  await ffmpeg.run(...command);
  await ffmpeg.FS("unlink", resultVideo.title);
  resultVideo["blob"] = ffmpeg.FS('readFile', title);
  return resultVideo.blob;
};


  


  These dependencies are used : "@ffmpeg/core" : " 0.8.5", "@ffmpeg/ffmpeg" : " 0.9.7". Upgrading the library to the latest version does not work either.

  


• Create video vom rendered OpenGL frames

  10 mai 2012, par MrMuh

  i am searching for a way to create a video from a row of frames i have rendered with OpenGL and transfered to ram as int array using the glGetTexImage function. is it possible to achieve this directly in ram ( 10 secs video) or do i have to save each frame to the harddisk and encode the video afterwards ?

  i have found this sample http://cekirdek.pardus.org.tr/ ismail/ffmpeg-docs/api-example_8c-source.html in an other SO question but is this still the best way to do it ?
