  • 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.

  • Les vidéos

    21 avril 2011, par

    Comme les documents de type "audio", Mediaspip affiche dans la mesure du possible les vidéos grâce à la balise html5 .
    Un des inconvénients de cette balise est qu’elle n’est pas reconnue correctement par certains navigateurs (Internet Explorer pour ne pas le nommer) et que chaque navigateur ne gère en natif que certains formats de vidéos.
    Son avantage principal quant à lui est de bénéficier de la prise en charge native de vidéos dans les navigateur et donc de se passer de l’utilisation de Flash et (...)

  • Dump WebRTC stream to a file

    20 novembre 2014, par Mondain

    I’d like to capture the audio and video from a WebRTC stream to a file or pair of files, if audio and video require their own individual files. The audio and video are not muxed together and are known to be available on a set of server udp ports :

    Port   Encoding
5000 - VP8 video
5001 - RTCP (for video)
5002 - Opus audio @48kHz 2 channels
5003 - RTCP (for audio)

    The SDP file / data is not available and DTLS may be used.

    I would prefer to use avconv or ffmpeg to capture the stream, unless a better tool is suggested.

    Edit : I’ve found that this as inquired will most likely not work. Until I hear otherwise, none of these tools support the initial DTLS handshake followed by the data transmission via SRTP.

  • ffmpeg video stream to app c# [on hold]

    3 septembre 2014, par Alexey Medvedev

    I am trying to make a video mixer for online broadcasts. To do this, I use ffmpeg and C #. I had a problem with the transfer of the video stream from ffmpeg to my program. I would like to receive a stream of ffmpeg using network protocols (e.g. TCP, UDP or others) or capturing if from ffplay window, but I don`t how I can do it. Can you give me some ideas ?

    For example, I have command for ffmpeg : "ffmpeg -i video1.mp4 -f mpegts udp:127.0.0.1:5000" or same command with other output formats or network protocols. How i can read video stream from the port and convert it to Bitmap ?
    I need to send video stream from my program from computer A to my program to computer B. I write program on C#. I dont know how I can compress video which I must send between my computers and I decided to use Ffmpeg. Now, I can streaming video from my program in computer A to ffmpeg and compress it with parameters which I need.
    On second computer I can read this steam using ffmpeg or ffplay, but I don`t know how I can get this stream into my program.
    1) How can I get this stream in my program ? Which libraries can you recommend me ?
    2) Do you know any libraries which can compress video, instead of using ffmpeg ?

  • Gstreamer errors when streaming on windows

    19 juillet 2014, par user2656632

    I tried to streaming video by gstreamer using this :

    Sender :

    gst-launch ksvideosrc ! ffmpegcolorspace ! ffenc_mpeg2video gop-size=1 ! mpegtsmux ! rtpmp2tpay ! udpsink host=127.0.0.1 port=5000

    Receiver :

    gst-launch udpsrc port=5000 caps="application/x-rtp, media=video, clockrate=90000, encoding-name=MP2TS" ! rtpmp2tdepay ! ffdemux_mpegts ! ffdec_mpeg2video ! ffmpegcolorspace ! directdrawsink

    It works, but wrong. I got very low fps and I got this output :
