  • How do I properly use Flutter FFmpegKit to convert video file formats to H.264?

    21 August 2024, by Spencer

    I've been using GPT and publications from Medium to help with my how I'm supposed to use the FFmpeg kit for Flutter but they have been no help. Perhaps I need clarification on what the tool is supposed to do because links like these below have not been of any help and are very outdated:

    


    https://dev.to/usp/flutter-live-streaming-a-complete-guide-2634

    


    https://medium.com/itnext/how-to-make-a-serverless-flutter-video-sharing-app-with-firebase-storage-including-hls-and-411e4fff68fa

    


    https://github.com/arthenica/ffmpeg-kit/blob/main/flutter/flutter/README.md

    


    This is the code i've been trying to run to convert a video file before I upload to Firestore Database.

    


    Future convertToH264(Uint8List bytes) async {
  try {
    final filename = const Uuid().v4();
    final tempDir = await getTemporaryDirectory();
    final tempVideoFile = File('${tempDir.path}/$filename.mp4');
    await tempVideoFile.writeAsBytes(bytes);
    final outputPath = '${tempDir.path}/$filename-aac.mp4';

    await FFmpegKit.execute(
      '-i ${tempVideoFile.path} -c:v libx264 -c:a aac $outputPath',
    );
    return await File(outputPath).readAsBytes();
  } catch (e) {
    rethrow;
  }
} 


    


  • Ways to create animations in python?

    21 May 2017, by Allison123

    What is the best way to create a small animation in python?
    So far, I have tried: tkinter and FuncAnimation (from animation in matplotlib- this is what is used in A Student’s Guide to Python for Physical Modeling).

    The goal is to make a set of simple animations, but FuncAnimation is having me install apt-get so that I can get ffmpeg so I can run the animation. It seems like a lot of downloading, which I don’t prefer if there is a similarly powerful alternative.

    If possible, I was hoping to integrate these animations into Pygame at a later time. Will that be possible?

    YES, this is a subjective question, but I am looking for guidance from experienced python animators. What are the objective strengths and weaknesses of different methods of animating in Python?
