• Live Video Encoding and Streaming on a Webpage

  15 juin 2018, 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 ?

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

  7 décembre 2017, par Matomo Core Team — Community

  In less than three weeks, Matomo (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, Matomo 2.X is supported for 12 months after the initial release of Matomo 3.0.0 which was on December 18th 2016. Therefore, Matomo 2 will no longer receive any updates after December 18th 2017.

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

  The update to Matomo (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 Matomo (Piwik) self-hosted and would like to be upgraded, plus your Matomo managed in the official Cloud-hosted service, contact InnoCraft Cloud and they will migrate your database.

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