  • La file d’attente de SPIPmotion

    28 novembre 2010, par

    Une file d’attente stockée dans la base de donnée
    Lors de son installation, SPIPmotion crée une nouvelle table dans la base de donnée intitulée spip_spipmotion_attentes.
    Cette nouvelle table est constituée des champs suivants : id_spipmotion_attente, l’identifiant numérique unique de la tâche à traiter ; id_document, l’identifiant numérique du document original à encoder ; id_objet l’identifiant unique de l’objet auquel le document encodé devra être attaché automatiquement ; objet, le type d’objet auquel (...)

  • GStreamer encountered a general stream error in Qt5 raspberry pi

    7 juin 2017, par Myanju

    I’m trying to play a video using QtMediaPlayer in Raspberry pi 2 B. The source code is as follows :

    QMediaPlayer *media;
    
QVideoWidget *video;
    
...
    
...
    
media = new QMediaPlayer(parent);
    
video = new QVideoWidget(parent);
    
media->setVideoOutput(video);
    
media->setMedia(QUrl::fromLocalFile("/home/pi/Desktop/test3.mp4"));
    
media->play();

    But the result is a blank video screen and the following error :

    ** (Bus:2148): WARNING **: ffmpegcolorspace-vo: size 1105920 is not a   
    
multiple of unit size 829440
    
Error: "GStreamer encountered a general stream error."

    System Information

    Running latest raspbian Jessie OS,
    Installed Qt5.3,
    Installed gstreamer0.10-plugins-good/bad/ugly/ffmpeg and
    Installed Mpeg-2 License

    Here is the video test3.mp4

    I ran this code in Windows with Qt5 installed ; it is working there. But it’s not working in the Raspberry pi. Please tell me what I’m missing here.

  • Storing high quality video stream (from IP Action Camera) continuously to a Storage Device and issues around Write-Speed bottlenecks

    21 mai 2017, par Aldo

    I am looking to get an Action Camera (Eken H8R, or a GoPro) for a project. Let me explain the scenario I have :

    I will obtain a live stream from the camera on to a Raspberry Pi (over WiFi) as shown here. Next, I want to continuously segment this live stream into 10-15 minute video clips and store them in an external Hard Drive (which is connected to the RPi). I am considering this thread, and the avconvcommand mentioned in the answer by Alexander.

    Now, my concern is write-speed limitations. The video stream would probably have a high bitrate, and might be 4k30fps, in which case file sizes would be huge. Would write speed to disk be a bottleneck ? If so, how will the Pi maintain a buffer to achieve this ? Could I run out of space as the memory stick on the Pi would only be around 8 gigs ? If so, what’s a better alternative ? Please correct me if I’m wrong on these as I’m only a beginner.
