  • ffmpeg_kit_flutter_full : Video created from ffmpeg not showing in the web

    16 December 2024, by Đoàn Thanh Thảo

    I am implementing a screen capture widget to create a video. The video was successfully created in MP4 format and I can view it in my app and then I posted it to my web. However, on the web, I cannot see the video preview, only when I download the video and view it on my phone can I see it. I think the problem is that there is some missing format that makes the video not playable on Https. Here is my code:

    


        final command = '-y -f image2 -i $imagesPath '
    '${fps != null ? "-r $fps" : ""} '
    '-vf "scale=2000:5000" '
    // '-vf "scale=iw*$scaleMultiplier:ih*$scaleMultiplier" '
    '-c:v mpeg4 -q:v $qValue -pix_fmt yuv420p -movflags +faststart $outputVideoPath';

  • launch ffmpeg on Maui Android

    4 December 2024, by lolveley

    I have an Maui app which is deployed on an Android tablet, a Samsung tab S9 FE.
I have copied the ARM8 version of the ffmpeg executable in the AppDataDirectory of my deployed app. The executable, named "ffmpeg", has the rights _rwxrwxrwx (the underscore means this is a file, and not a directory).

    


    I try to execute the file with the command Process.Start:

    


    private void GetThumbnail(string inputFile, string imageFullPath, string ffmpegFullPath)
{
        ProcessStartInfo startInfo = new ProcessStartInfo();

        string arguments = $"-i {inputFile} -ss 00:01:00.000 -vframes 1 {imageFullPath}";

        startInfo.FileName = ffmpegFullPath;
        startInfo.CreateNoWindow = false;
        startInfo.UseShellExecute = false;
        startInfo.RedirectStandardError = true;
        startInfo.RedirectStandardOutput = true;
        startInfo.Arguments = arguments;

        try
        {
            Process process = Process.Start(startInfo);
            process.WaitForExit(5000);
            process.Close();
        }
        catch(Exception ex)
        {
            Console.WriteLine(ex.Message);
        }
}


    


    There is an exception saying the access is denied:

    


    


    System.ComponentModel.Win32Exception (13): An error occurred trying to
start process '/data/user/0/sxb.explorateur.de.fichiers/files/ffmpeg'
with working directory '/data/data/sxb.explorateur.de.fichiers/files'.
Permission denied

    


    


    The error message doesn't say more, and I do not see what to do, the directory usually is dedicated to the application, and the file is executable.

    


    I know that Android has restricted policies with file execution, and maybe it's even harder for the Samsung operating system, namely One UI 6.1.1 and Android 14.

    


    thank you.

    


  • How to share video stream to WSL2 while ffmpeg? [closed]

    27 October 2024, by 笑先生

    Most solutions for using a camera in WSL are to build your own WSL kernel. I have realized it with the steps mentioned in Capturing webcam video with OpenCV in WSL2

    


    However, it's complicated and time-consuming. I want to realize it by sharing video streaming.

    


    Share method

    


    Step1: Run the command below on Windows to check all the camera devices. I see an integrated camera "Integrated Webcam" (video) in the output.

    


    ffmpeg -list_devices true -f dshow -i dummy


    


    Step2: Check the IP of Ethernet adapter vEthernet (WSL). In my computer, it's 172.24.176.1

    


    Step3: Run the command below on Windows to share video streaming.

    


    ffmpeg -f dshow -i video="Integrated Webcam" -preset ultrafast -tune zerolatency -vcodec libx264 -f mpegts udp://172.24.176.1:5000


    


    Test

    


    Run the command to play the video streaming: ffplay udp://172.24.176.1:5000

    


    It can show the video when the command is run with a terminal of Windows (Win10).

    


    But, it cannot show anything when the command is run on with a terminal of WSL (Ubuntu 22.04). Why?
