  • Piwik 2 reaches end of life soon (December 2017), update now !

    7 décembre 2017, par Piwik Core Team — Community

    In less than three weeks, Piwik 2 will be no longer supported. This means that no further (security) updates will be released for this version. As per our Long Term Support announcement, Piwik 2.X is supported for 12 months after the initial release of Piwik 3.0.0 which was on December 18th 2016. Therefore, Piwik 2 will no longer receive any updates after December 18th 2017.

    It has been almost a year since we released Piwik 3 and we highly recommend updating to Piwik 3 ASAP. The major new release came with a new UI, performance and security improvements. If you are still on Piwik 2, the security improvements alone should be worth updating your Piwik to Piwik 3 now. We cannot recommend this enough.

    The update to Piwik 3 should be smooth, but may take a while depending on the amount of data you have.

    • If you have any problem with the update, feel free to get in touch with us, or ask in the forums.
    • If you are currently using Piwik self-hosted and would like to be upgraded, plus your Piwik managed in the official Cloud-hosted service, contact InnoCraft Cloud and they will migrate your database.

    At Piwik and InnoCraft, the company of the makers of Piwik, we have seen many thousands of Piwik installations upgraded over the past year and look forward to an exciting future for Piwik 3 and beyond !

  • Real time livestreaming - RPI FFmpeg and H5 Player

    29 avril 2022, par Victor

    I work at a telehealth company and we are using connected medical devices in order to provide the doctor with real time information from these equipements, the equipements are used by a trained health Professional.

    


    Those devices work with video and audio. Right now, we are using them with peerjs (so peer to peer connection) but we are trying to move away from that and have a RPI with his only job to stream data (so streaming audio and video).

    


    Because the equipements are supposed to be used with instructions from a doctor we need the doctor to receive the data in real time.

    


    But we also need the trained health professional to see what he is doing (so we need a local feed from the equipement)

    


    How do we capture audio and video

    


    We are using ffmpeg with a go client that is in charge of managing the ffmpeg clients and stream them to a SRS server.
This works but we are having a 2-3 sec delay when streaming the data. (rtmp from ffmpeg and flv on the front end)

    


    ffmpeg settings :

    


    ("ffmpeg", "-f", "v4l2", `-i`, "*/video0", "-f", "flv", "-vcodec", "libx264", "-x264opts", "keyint=15", "-preset", "ultrafast", "-tune", "zerolatency", "-fflags", "nobuffer", "-b:a", "160k", "-threads", "0", "-g", "0", "rtmp://srs-url")


    


    My questions

    


      

    • Is there a way for this set up to achieve low latency (<1 sec) (for the nurse and for the doctor) ?

      • &#xA;

    • Is the way I want to achieve this good ? Is there a batter way ?

    Note : The nurse and doctor use HTTP-FLV to play the live stream, for low latency.

  • Ubuntu ffmpeg command -i not found

    12 avril 2016, par Gerwin

    I’m a beginner with Ubuntu and I need to setup a streaming server for my company, I’ve installed NGINX and FFMPEG, but when I call ffmpeg -i in the ~/ffmpeg/ffmpeg directory it returns an error command not found but when I call ./ffmpeg -i it returns a list with configurations.. why does ffmpeg -i not work and how can I fix it ?

    I think that the Path Enviroment Variable is incorrect but how would I go abouts changing said variable ? I’m not that experienced with Ubuntu / CMD programming / FFMPEG configuration.
