  • Supporting all media types

    13 avril 2011, par

    Unlike most software and media-sharing platforms, MediaSPIP aims to manage as many different media types as possible. The following are just a few examples from an ever-expanding list of supported formats : images : png, gif, jpg, bmp and more audio : MP3, Ogg, Wav and more video : AVI, MP4, OGV, mpg, mov, wmv and more text, code and other data : OpenOffice, Microsoft Office (Word, PowerPoint, Excel), web (html, CSS), LaTeX, Google Earth and (...)

  • Open .avi with OpenCV 2.4 & Ubuntu 11.04

    25 juin 2012, par CTZStef

    I try to open and read video files in .avi format using OpenCV. Here is my code :

    void MainWindow::on_actionOuvrir_fichier_triggered()
    
 140    +   {
    
 141    +    //mettre a -1 streamId
    
 142    +    streamId = -1;
    
 143    +    //ouvrir fenetre navigation fichiers pour recuperer path vers .avi
    
 144    +    QString fileName = QFileDialog::getOpenFileName(this,tr("Ouvrir fichier video"),"/home",
    
 145    +    tr("Videos (*.avi)"));
    
 146    +    std::string utf8_text = fileName.toUtf8().constData();
    
 147    +    //ouvrir .avi
    
 148    +    capture = new VideoCapture(utf8_text);
    
 149    +    //check ouverture
    
 150    +    if(!capture->isOpened())
    
 151    +    cout << "probleme ouverture fichier video" << endl;
    
 152    +    //calculer delay between each frame in ms
    
 153    +    rate = capture->get(CV_CAP_PROP_FPS);
    
 154    +    delay = 1000 / rate;
    
 155    +    //demarrer timer recordId
    
 156    +    recordId = startTimer(delay);
    
 157    +    //capture premiere frame
    
 158    +    if(!capture->read(in))
    
 159    +    cout << "probleme lecture frame fichier video" << endl;
    
 160    +   }

    I get no problem at compilation time, but I can't open a video file. While in debug mode I saw that string utf8_text had the good absolute path to my video, so obviously the problem comes from the constructor of the VideoCapture object. Then, I tried to install every codec pack I could or thought was relevant. But the problem is still there, capture->isOpened() still returns false, and in debug mode I can see that capture contains nothing.

    I am lost here, don't know what to try next. Any idea ??

    Thanks !!!

    thanks

    [EDIT 2]

    I have just read this in the book OpenCV 2 Computer Vision Application Programming Cookbook by R. Laganiere :

    It is important to note that in order to open the specified video
    file, your computer must have the corresponding codec installed,
    otherwise cv::VideoCapture will not be able to understand the input
    file. Normally, if you are able to open your video file with a video
    player on your machine (such as the Windows Media Player), then OpenCV
    should also be able to read this file.

    Well, on my machine it is not that easy mister Laganiere... I hate this book.

  • FFmpeg copying from udp to rtsp

    28 décembre 2014, par ladi2000

    So I have a (live)video stream on udp ://10.5.5.100:8463 and I copy it to udp ://localhost:1000.

    ffmpeg -f mpegts -i "udp://10.5.5.100:8554?fifo_size=10000" -f mpegts -vcodec copy udp://localhost:1000/go

    And it works fine in VLC but Wirecast doesn’t accept udp ://..., but it accepts rtsp ://...

    but I don’t now much about ffmpeg, so I only changed udp to rtsp

    ffmpeg -f mpegts -i "udp://10.5.5.100:8554?fifo_size=10000" -f mpegts -vcodec copy rtsp://localhost:1000/go

    But it doesn’t work and outputs this

    rtsp://localhost:1000/go: Protocol not found

    Thank you for answers !!
