• Uncaught SyntaxError : Unexpected token ' ' using videojs - ffmpegjs plugin and multiple plugins issue

  6 octobre 2020, par Muhammad Faheem

  I'm trying to use ffmpegjs plugin into videojs but getting error

  


  


  "Uncaught SyntaxError : Unexpected token '<'".

  &#xA;

  &#xA;

  Also don't know how to use multiple plugins in videojs. Wanna use ffmpeg along with ts-ebml.

  &#xA;

  This is how I'm using in videojs options :

  &#xA;

  options: {
                controls: true,
                bigPlayButton: false,
                loop: false,
                width: 600,
                height: 340,
                fluid: false,
                plugins: {
                    wavesurfer: {
                        backend: "WebAudio",
                        waveColor: "#ffffff",
                        backgroundColor: "#000000",
                        barHeight: 3,
                        progressColor: "white",
                        debug: true,
                        cursorWidth: 1,
                        displayMilliseconds: true,
                        hideScrollbar: true,
                        plugins: [
                            // enable microphone plugin
                            WaveSurfer.microphone.create({
                                bufferSize: 4096,
                                numberOfInputChannels: 1,
                                numberOfOutputChannels: 1,
                                constraints: {
                                    video: false,
                                    audio: true
                                }
                            })
                        ]
                    },
                    record: {
                        audio: true,
                        video: false,
                        maxLength: 3600,
                        debug: true,
                        // enable ffmpeg.js plugin
                        convertEngine: "ffmpeg.js",
                        // convert recorded data to MP3
                        convertOptions: ["-f", "mp3", "-codec:a", "libmp3lame", "-qscale:a", "2"],
                        // specify output mime-type
                        pluginLibraryOptions: {
                            outputType: "audio/mpeg"
                        },
                        // use MP4 encoding worker (H.264 & AAC & MP3 encoders)
                        convertWorkerURL: "../../../../node_modules/ffmpeg.js/ffmpeg-worker-mp4.js"
                    }
                }

• Offline tracking in Matomo JavaScript Tracker – We need your feedback

  16 octobre 2020, par Matomo Core Team — Development, Uncategorized

  As part of our Matomo 4 release we are working on adding support for offline tracking using service workers (SW) and IndexedDB. An early version of this new feature is now available as part of our latest Matomo 4 beta and we now need your feedback to fix any outstanding issues.

  How does it work behind the scenes ?

  • The service worker caches the Matomo JavaScript tracker so if a user becomes offline on subsequent requests the JS tracker will be still loaded.
  • If a user is offline, any tracking request will be put into the local IndexedDB.
  • Once the user becomes online, all requests from the IndexedDB will be retried.

  How do I integrate offline tracking into my website or app ?

  Follow the steps in our FAQ on how to set up offline tracking. 

  We need your feedback

  We’d love to hear your feedback if this new feature is working for you or not. Simply leave a comment on the offline tracking issue and let us know if it worked for you, if something didn’t work, whether you miss any options or any other kind of feedback.

  Are you a service worker or IndexedDB pro ? We’d love if you could help us review our implementation. You can check out the code in the offline tracking pull request. We appreciate any feedback to help us improve this feature !

  Thank you for your help !

• RTSP to RTMP using FFMPEG on Raspberry Pi to YouTube Livestream ends prematurely (and sometimes doesn't start)

  12 mars 2021, par user203875

  I have been running a program from my raspberry pi 4 that converts a RTSP network camera feed to RTMP for YouTube. The stream used to run non-stop every day. I didn't have to do anything. I have a program in place that would restart if the feed died.

  &#xA;

  Nothing has changed with that program in 2 years. About a month ago, the feed stopped working. I just started into trying to figure out why. Maybe someone has some ideas on what is going on ?

  &#xA;

  In order for me to start the feed, I must also start a studio.youtube.com browser session showing the feed information. If that web page is up and running, the live stream will start. While I can't say for certain that it NEVER starts without this session running, it seems that way.

  &#xA;

  Usually the stream lasts for an hour or two. Rarely more than four hours.

  &#xA;

  When I start up a studio.youtube.com session after the stream dies the "Dimiss" or "Edit in Studio" message is on the page. I have to hit "dismiss" before I can start up the stream again.

  &#xA;

  Is there a solution to this ?

  &#xA;

  Again, my program didn't change, so I'm at a loss for what I can do to fix this.
