    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 (...)

  • Live Video Encoding and Streaming on a Webpage

    9 mars 2016, par Ockhius

    I am trying to show live webcam video stream on webpage and I have a working draft. However, I am not satisfied with the performance and looking for a better way to do the job.

    I have a webcam connected to Raspberry PI and a web server which is a simple python-Flask server. Webcam images are captured by using OpenCV and formatted as JPEG. Later, those JPEGs are sent to one of the server’s UDP ports. What I did up to this point is something like a homemade MJPEG(motion-jpeg) streaming.

    At the server-side I have a simple python script that continuously reads UDP port and put JPEG image in the HTML5 canvas. That is fast enough to create a perception of a live stream.

    Problems :

    • This compress the video very little. Actually it does not compress the video. It only decreases the size of a frame by formatting as JPEG.

    • FPS is low and also quality of the stream is not that good.

    • It is not a major point for now but UDP is not a secure way to stream video.

    • Server is busy with image picking from UDP. Needs threaded server design.

    Alternatives :

    • I have used FFMPEG before to convert video formats and also stream pre-recorded video. I guess, it is possible to encode(let say H.264) and stream WebCam live video using ffmpeg or avconv. (Encoding)

    Is this applicable on Raspberry PI ?

    • VLC is able to play live videos streamed on network. (Stream)

    Is there any Media Player to embed on HTML/Javascript to handle
    network stream like the VLC does ?

    • I have read about HLS (HTTP Live Stream) and MPEG-DASH.

    Does these apply for this case ? If it does,how should I use them ?

    Is there any other way to show live stream on webpage ?

    • RTSP is a secure protocol.

    What is the best practice for transport layer protocol in video
    streaming ?
