    MediaSPIP platforms can be installed as a farm, with a single "core" hosted on a dedicated server and used by multiple websites.
    This allows (among other things) : implementation costs to be shared between several different projects / individuals rapid deployment of multiple unique sites creation of groups of like-minded sites, making it possible to browse media in a more controlled and selective environment than the major "open" (...)

  • ffmpeg is not capturing udp output

    30 octobre 2020, par Dzidas

    I'm trying to capture UDP output with ffmpeg, but the stream looks empty. Just for background, the output is produced by GoPro camera and I'm connecting to its Wifi. I can see with wireshark a lot of udp packets sent to my ip from GoPro IP, but nothing appears in ffmpeg.

  • USB webcam streaming in ARM board (i.MX6)

    5 septembre 2017, par Titus

    I want to streaming the camera via NETWORK. I have connected the USB webcam to i.MX6 board and want to stream in Ubuntu14.04/16.04 via network.

    Incidentally, I have installed the gstreamer and ffmpeg tools for this in i.MX6 board.

    Also I am able to stream USB webcam within Ubuntu14.04 PC using the following ffmpeg commands. But it’s also not working if I use ffplay in other Ubuntu16.04 and I am not sure why (both are same ffmpeg versions).

    ffmpeg -f v4l2 -i /dev/video0 -preset ultrafast -vcodec libx264 -tune zerolatency -b 900k -f mpegts udp://192.168.0.37:1234

    Finally I want to stream with different ARM boards. Am also not able to build ffplay command. Same issue with raspberry pi too. I am doing something wrong or misunderstood something here ?

    I'm not trying to record this, just trying to directly play from the Elgato Cam Link 1:1 output to my computer screen. When this is played in the Elgato Game Capture software, the video and audio are 1:1, no issues. So I know it's not the console or the capture device.
