  • Le plugin : Podcasts.

    14 juillet 2010, par

    Le problème du podcasting est à nouveau un problème révélateur de la normalisation des transports de données sur Internet.
    Deux formats intéressants existent : Celui développé par Apple, très axé sur l’utilisation d’iTunes dont la SPEC est ici ; Le format "Media RSS Module" qui est plus "libre" notamment soutenu par Yahoo et le logiciel Miro ;
    Types de fichiers supportés dans les flux
    Le format d’Apple n’autorise que les formats suivants dans ses flux : .mp3 audio/mpeg .m4a audio/x-m4a .mp4 (...)

  • Ajouter notes et légendes aux images

    7 février 2011, par

    Pour pouvoir ajouter notes et légendes aux images, la première étape est d’installer le plugin "Légendes".
    Une fois le plugin activé, vous pouvez le configurer dans l’espace de configuration afin de modifier les droits de création / modification et de suppression des notes. Par défaut seuls les administrateurs du site peuvent ajouter des notes aux images.
    Modification lors de l’ajout d’un média
    Lors de l’ajout d’un média de type "image" un nouveau bouton apparait au dessus de la prévisualisation (...)

  • Emballe médias : à quoi cela sert ?

    4 février 2011, par

    Ce plugin vise à gérer des sites de mise en ligne de documents de tous types.
    Il crée des "médias", à savoir : un "média" est un article au sens SPIP créé automatiquement lors du téléversement d’un document qu’il soit audio, vidéo, image ou textuel ; un seul document ne peut être lié à un article dit "média" ;

  • Is there any possibility to transcode a h264 hls/m3u8 live stream into another HEVC (h265) hls/m3u8 live stream using FFmpeg in real time ?

    2 septembre 2024, par Ghenadie Pripa

    The command I used :

    


    ffmpeg -i  https://tezaurtv.md/wp-content/uploads/live/index.m3u8 -c:v libx265 -b:v 1500k -tag:v hvc1 -c:a aac -b:a 128k -f hls -hls_time 10 -hls_list_size 10 -hls_flags delete_segments+append_list+program_date_time -hls_playlist_type event -hls_segment_type mpegts -hls_segment_filename "D:/BRUT/HLS/test/stream_%d.ts" -vsync 2 -rtbufsize 500M -loglevel debug D:/BRUT/HLS/test/stream.m3u8


    


    I tried a lot of commands and parameters but nothing helps. The experiment is on local Windows. Transcode with ffmpeg and play with FFplay.

    


    The problem is the following : After I start stream.m3u8 to play after a few seconds the picture and sound stops. What is wrong in the FFmpeg command ?

  • Why when using ffmpeg to create in real time avi video file from images the avi file is playing with purple noisy color ?

        {
    
            p.Close();
    
        }
    
    }
    
}

    And i’m using it in form1 in a button click event :

    private void button1_Click(object sender, EventArgs e)
    
        {
    
            timer1.Start();
    
        }

    the directroy screenshots is where i’m taking a screenshot every 100ms in the timer1 tick event :

        ScreenShot shot = new ScreenShot();
    
    public static int counter = 0;
    
    private void timer1_Tick(object sender, EventArgs e)
    
    {
    
        counter++;
    
        shot.GetScreenShot(@"e:\screenshots\", "screenshot");
    
        if (counter == 1200)
    
        {
    
            timer1.Stop();
    
        }
    
    }

    I’m calling the method PushFrame from inside the ScreenShot class where i save the screenshots.

    Ffmpeg fmpeg;

    Then :

    fmpeg = new Ffmpeg();
    
fmpeg.Start(@"e:\screenshots\test.avi", 25);

    And :

    public Bitmap GetScreenShot(string folder, string name)
    
    {
    
        _screenShot = new Bitmap(GetScreen());
    
        System.GC.Collect();
    
        System.GC.WaitForPendingFinalizers();
    
        string ingName = folder + name + Elgato_Video_Capture.counter.ToString("D6") + ".bmp";
    
        _screenShot.Save(ingName);
    
        fmpeg.PushFrame(_screenShot);
    
        _screenShot.Dispose();
    

    
        return _screenShot;
    
    }

    All the images on the hard disk are fine i can edit/open them and watch them no problems.
    They are also same size.

    The result in the end is one big avi file 1.08 GB size.
    But when i play it i see many windows running inside very fast and all painted with noisy purple color.

    Here a screenshot from the video file when playing it :

    avi file playing screenshot

    I think the problem is somewhere in the Ffmpeg class where i give parameters to the ffmpeg.exe

    psi.Arguments = @"-f rawvideo -pix_fmt yuv420p -video_size 1920x1080 -i \\.\pipe\mytestpipe -map 0 -c:v mpeg4 -r " + BitmapRate + " " + outPath;

    Not sure what make this avi file to look like that.

    This is the video file the result i got : https://www.youtube.com/watch?v=fdxPus-Xv1k&feature=youtu.be
