  • HTML5 audio and video support

    13 avril 2011, par

    MediaSPIP uses HTML5 video and audio tags to play multimedia files, taking advantage of the latest W3C innovations supported by modern browsers.
    The MediaSPIP player used has been created specifically for MediaSPIP and can be easily adapted to fit in with a specific theme.
    For older browsers the Flowplayer flash fallback is used.
    MediaSPIP allows for media playback on major mobile platforms with the above (...)

  • De l’upload à la vidéo finale [version standalone]

    31 janvier 2010, par

    Le chemin d’un document audio ou vidéo dans SPIPMotion est divisé en trois étapes distinctes.
    Upload et récupération d’informations de la vidéo source
    Dans un premier temps, il est nécessaire de créer un article SPIP et de lui joindre le document vidéo "source".
    Au moment où ce document est joint à l’article, deux actions supplémentaires au comportement normal sont exécutées : La récupération des informations techniques des flux audio et video du fichier ; La génération d’une vignette : extraction d’une (...)

  • C# on linux : FFmpeg (FFMediaToolkit) MediaOutput..Video.AddFrame(FrameToImageData(ImageData)) causes program to exit with code 139

    19 mai 2021, par Jan Černý

    In my C# program I have instance of MediaOutput from FFMediaToolkit. It is initialized like this :

    


    MediaOutput buffer = MediaBuilder.CreateContainer(videoPath).WithVideo(new VideoEncoderSettings(width: width,
                height: height, framerate: frameRate,
                codec: VideoCodec.H264)
            ).Create();


    


    When I want to add frame to buffer I use this code :

    


    private static ImageData FrameToImageData(Bitmap bitmap) {
    Rectangle rect = new Rectangle(System.Drawing.Point.Empty, bitmap.Size);
    BitmapData bitLock = bitmap.LockBits(rect, ImageLockMode.ReadOnly, PixelFormat.Format24bppRgb);
    ImageData bitmapImageData = ImageData.FromPointer(bitLock.Scan0, ImagePixelFormat.Bgr24, bitmap.Size);
    bitmap.UnlockBits(bitLock);
    return bitmapImageData;
}

public void AddFrame(Bitmap frame) {
    buffer.Video.AddFrame(FrameToImageData(frame));
}


    


    But when code reaches buffer.Video.AddFrame(); it exits with code 139 without throwing any exception.

    


    I have two test files and only one is causing it. One is .png file 100x100 and it works fine. The other is .png file 1000x1000 and it makes program exit as soon as it reaches this method.

    


    What exit code 139 means in C# ?
    
How can I diagnose this problem when it is not throwing any exceptions ?
    
How can I fix it ?

    


    Thank you for help. If you need any more information, leave a comment and I will add it soon as possible.

  • Python opencv ffmpeg threading exit functions

    29 novembre 2020, par scacchi

    i'm trying to finish the audio/video recording loop by pressing a key (or by other event), if i use the simple time.sleep() in the main loop work perfectly, after 5 second stop video and create file, if i use the function keyboard_pressed() doesnt execute stop_AVrecording() correctly and file_manager().
What's im doing wrong ?
Thanks in advance
