  • Installation en mode ferme

    4 février 2011, par

    Le mode ferme permet d’héberger plusieurs sites de type MediaSPIP en n’installant qu’une seule fois son noyau fonctionnel.
    C’est la méthode que nous utilisons sur cette même plateforme.
    L’utilisation en mode ferme nécessite de connaïtre un peu le mécanisme de SPIP contrairement à la version standalone qui ne nécessite pas réellement de connaissances spécifique puisque l’espace privé habituel de SPIP n’est plus utilisé.
    Dans un premier temps, vous devez avoir installé les mêmes fichiers que l’installation (...)

  • HTML5 audio and video support

    13 avril 2011, par

    MediaSPIP uses HTML5 video and audio tags to play multimedia files, taking advantage of the latest W3C innovations supported by modern browsers.
    The MediaSPIP player used has been created specifically for MediaSPIP and can be easily adapted to fit in with a specific theme.
    For older browsers the Flowplayer flash fallback is used.
    MediaSPIP allows for media playback on major mobile platforms with the above (...)

  • FFmpeg - frame delays double after the audio was added

    30 septembre 2018, par Franklin Tao

    single video delays 49ms

    ffmpeg -rtbufsize 100M  -f dshow -i video="Logitech HD Webcam C270"  -vcodec libx264 -r 30-g 5  -preset:v ultrafast -tune:v zerolatency -f rtsp rtsp://127.0.0.1:80/live/test

    The delay was 100 ms after adding audio.

    ffmpeg -rtbufsize 100M  -f dshow -i video="Logitech HD Webcam C270":audio="麦克风 (HD Webcam C270)"  -vcodec libx264 -g 5 -r 30  -acodec aac -preset:v ultrafast -tune:v zerolatency -f rtsp rtsp://127.0.0.1:80/live/tao

    Is it normal ? Is there any solution to reduce the delay ?

  • How to share video stream to WSL2 while ffmpeg ? [closed]

    27 octobre 2024, par 笑先生

    Most solutions for using a camera in WSL are to build your own WSL kernel. I have realized it with the steps mentioned in Capturing webcam video with OpenCV in WSL2

    


    However, it's complicated and time-consuming. I want to realize it by sharing video streaming.

    


    Share method

    


    Step1 : Run the command below on Windows to check all the camera devices. I see an integrated camera "Integrated Webcam" (video) in the output.

    


    ffmpeg -list_devices true -f dshow -i dummy


    


    Step2 : Check the IP of Ethernet adapter vEthernet (WSL). In my computer, it's 172.24.176.1

    


    Step3 : Run the command below on Windows to share video streaming.

    


    ffmpeg -f dshow -i video="Integrated Webcam" -preset ultrafast -tune zerolatency -vcodec libx264 -f mpegts udp://172.24.176.1:5000


    


    Test

    


    Run the command to play the video streaming : ffplay udp://172.24.176.1:5000

    


    It can show the video when the command is run with a terminal of Windows (Win10).

    


    But, it cannot show anything when the command is run on with a terminal of WSL (Ubuntu 22.04). Why ?

    


  • FFmpeg : How to get AVPacket from OSX CMSampleBufferRef

    30 mars 2015, par wao813

    I’m new in AV technology and have been trying to combine FFmpeg with Apple’s CoreVideo framework to process webcam captures.

    First, i have webcam captures from CoreVideo(which could be found from AVCaptureVideoDataOutputSampleBufferDelegate) represented by CMSampleBuffer

    - (void)captureOutput:(AVCaptureOutput *)captureOutput
    
  didOutputSampleBuffer:(CMSampleBufferRef)sampleBuffer 
    
  fromConnection:(AVCaptureConnection *)connection {}

    From that, without store as temporary file, I would like to make it to FFmpeg’s AVPacket so I can process.

    Does anyone know which FFmpeg api I should be looking into ?
