  • Support de tous types de médias

    10 avril 2011

    Contrairement à beaucoup de logiciels et autres plate-formes modernes de partage de documents, MediaSPIP a l’ambition de gérer un maximum de formats de documents différents qu’ils soient de type : images (png, gif, jpg, bmp et autres...) ; audio (MP3, Ogg, Wav et autres...) ; vidéo (Avi, MP4, Ogv, mpg, mov, wmv et autres...) ; contenu textuel, code ou autres (open office, microsoft office (tableur, présentation), web (html, css), LaTeX, Google Earth) (...)

  • Convert youtube video files with ffmpeg to a format that can be playable on ios devices

    26 décembre 2018, par Amin

    I’ve created a telegram robot that downloads YouTube files and sends them to the user. Since most of our users use ios devices, Our first priority is ios.
    Videos files play on Windows and Android but not broadcast on ios.
    I convert format with ffmpeg after download from youtube :

    ffmpeg -i input.mp4 -strict -2 -vcodec mpeg4 output.mp4

    But in addition to prolonging the processing time, the file size increases and eventually the file will not run again in ios.

  • FFmpeg live stream to Youtube with Raspberry Pi & USB Camera — What command to use for better quality ?

    4 août 2023, par qwet142

    I am currently streaming to Youtube live with the following command :

    


    ffmpeg -re -f s16le -i /dev/zero -f v4l2 -thread_queue_size 512 -codec:v mjpeg -s 1920x1080 -i /dev/video0 -c:v libx264 -preset ultrafast -acodec aac -b:v 3500k -g 30 -f flv rtmp://a.rtmp.youtube.com/live2/key

    


    The frame rate is great, and the speed is 1x. However, the quality is very poor, improved only slightly after increasing the bitrate to 3000k. Changing the resolution doesn't help, and using veryfast makes things worse. How can I fix the quality ?

    


    Note : there is no audio and this is a USB camera.

    


  • c# pipe using youtube-dl to ffmpeg

    1er janvier 2017, par lilscarecrow

    I am trying to pipe the audio stream from youtube-dl into ffmpeg for a program using discord.NET. I am not sure exactly how to achieve this in c#, though. Currently, I can play ffmpeg with a url or path from this code on the docs for discord.NET :

    var process = Process.Start(new ProcessStartInfo
    
        {                                                      
    
            FileName = "ffmpeg",
    
            Arguments = $"-i {outLine.Data}" +                                              
    
                        " -f s16le -ar 48000 -ac 2 pipe:1",                                         
    
            UseShellExecute = false,
    
            RedirectStandardOutput = true                                                                                   
    
        });
    
        Thread.Sleep(2000);                                                                                                                     
    
        int blockSize = 3840;                                                                                                         
    
        byte[] buffer = new byte[blockSize];
    
        int byteCount;
    

    
        while (!playing)                                                                                                  
    
        {
    
            byteCount = process.StandardOutput.BaseStream                                                  
    
                    .Read(buffer, 0, blockSize);                                                                          
    

    
            if (byteCount == 0)                                                                                                             
    
                break;                                                                                                                          
    

    
            _vClient.Send(buffer, 0, byteCount);                                                                    
    
        }
    
        _vClient.Wait();

    So, I am trying to pipe the youtube-dl audio to this I assume. I just have no idea how to achieve piping in this format and for the file while it is downloading. Also, the program works on async if that helps.
