    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.

  • Why when creating video file with ffmpeg when playing the video file the video is moving very fast ?

    22 août 2013, par user2704319

    This is how I am using the ffmpeg arguments :

    public void Start(string pathFileName, int BitmapRate)
    
        {
    
            try
    
            {
    
                string outPath = pathFileName;
    
                Logger.Write("Output Video File Directory: " + outPath);
    
                Logger.Write("Frame Rate: " + BitmapRate.ToString());
    
                p = new NamedPipeServerStream(pipename, PipeDirection.Out, 1, PipeTransmissionMode.Byte);
    
                b = new byte[1920 * 1080 * 3]; // some buffer for the r g and b of pixels of an image of size 720p
    

    
                ProcessStartInfo psi = new ProcessStartInfo();
    
                psi.WindowStyle = ProcessWindowStyle.Hidden;
    
                psi.UseShellExecute = false;
    
                psi.CreateNoWindow = true;
    
                psi.FileName = ffmpegFileName; // the ffmpegFileName is the ffmpeg.exe !
    
                Logger.Write("psi.FileName: " + psi.FileName);
    
                psi.WorkingDirectory = workingDirectory;
    
                Logger.Write("psi.WorkingDirectory: " + psi.WorkingDirectory);
    
                psi.Arguments = @"-f rawvideo -pix_fmt bgr0 -video_size 1920x1080 -i \\.\pipe\mytestpipe -map 0 -c:v libx264 -r " + BitmapRate + " " + outPath;
    
                Logger.Write("ProcessStartInfo Arguments" + @"-f rawvideo -pix_fmt bgr0 -video_size 1920x1080 -i \\.\pipe\mytestpipe -map 0 -c:v libx264 -r " + BitmapRate + " " + outPath);
    
                //psi.RedirectStandardOutput = true;
    
                process = Process.Start(psi);
    
                process.EnableRaisingEvents = false;
    
                p.WaitForConnection();
    
            }
    
            catch (Exception err)
    
            {
    
                Logger.Write("Exception Error: " + err.ToString());
    
            }
    
        }

    I guess it is something with the arguments command, but I am not sure where the problem is.
    I tried to google and saw that you can use h264 or libx264 only with an mp4 output file ?

    How can I fix this ?

    When I am running the video file on any player I see everything moving very fast.

    This is a screenshot of the ffmpeg cmd window :

    And this is a link for the video file it created 1.37MB size and only 3 seconds length playing it with Media Player Classic :

  • How can I stream mjpeg file as rtsp

    24 août 2013, par Ilya Yevlampiev

    We have an mjpeg video, obtained from the webcam and stored into *.avi file, still encoded as mjpeg.

    We need to restream this file as rtsp (and stil preserve the mjpeg there, i.e. no decoding). The goal is to emulate the webcam this video was obtained from for the software that processes the video. The file can be open with vlc/ffplay with no problems. The ffmpeg behaves like it is streaming it, however, ffplay/vlc can't open this stream.

    We tried to stream if with gstreamer.

    1) we fount no free rtsp sink element for gstreamer pipeline. So, is there a free analogue for rtspsink to launch this pipeline with gst-launch ? we need and only cast, so we don't need so advanced element as rtspsink is.

    2) we also tried to build own simple rtsp server as described in http://weeklybuild.com/2013/01/creating-an-rtsp-stream-with-gstreamer/

    replacing videotestsrc with filesrc ; but what kind of elements we should use there ? usage of an only filesrc doesn't help ; we get the same problem as if we stream with ffmpeg. But what kind of lements we need there, if we dont' wan to decode/encode it, just to stream the file (to reproduce the thing what the webcam actually does).

    What is the problem ?
    this is the ffmpeg code that convert the video :

    Thanks
