La sauvegarde automatique de canaux SPIP
1 April 2010, byDans le cadre de la mise en place d’une plateforme ouverte, il est important pour les hébergeurs de pouvoir disposer de sauvegardes assez régulières pour parer à tout problème éventuel.
Pour réaliser cette tâche on se base sur deux plugins SPIP : Saveauto qui permet une sauvegarde régulière de la base de donnée sous la forme d’un dump mysql (utilisable dans phpmyadmin) mes_fichiers_2 qui permet de réaliser une archive au format zip des données importantes du site (les documents, les éléments (...) -

mpeg-dash live streaming can't fetch chunks
27 June 2020, by user1902653I'm trying to create a live stream of mpeg-dash with ffmpeg.


I'm streaming with python the frames to the ffmpeg process.


This is the current command I'm using for creating the mpeg-dash manifest and m4s files:


ffmpeg -re -f rawvideo -pix_fmt bgr24 -video_size 640x360 -i - -vcodec libx264 -preset ultrafast -tune zerolatency -f dash -window_size 10 -use_template 1 -use_timeline 0 -live 1 /srv/http/dash/stream.mpd



I'm using nginx as a server for now and I've created a simple index.html using shaka player, but the problem is I couldn't get it to load and play more then the first chunk. (checked with dev-tools in chrome in the network tab)


This is how I'm using shaka player right now:





 
 <code class="echappe-js"><script src="https://cdnjs.cloudflare.com/ajax/libs/shaka-player/2.1.4/shaka-player.compiled.js"></script>

<script>&#xA; var manifestUri = &#x27;stream.mpd&#x27;;&#xA; function initApp() {&#xA; shaka.polyfill.installAll();&#xA; if (shaka.Player.isBrowserSupported()) {&#xA; initPlayer();&#xA; } else {&#xA; console.error(&#x27;Browser not supported!&#x27;);&#xA; }&#xA; }&#xA; function initPlayer() {&#xA; var video = document.getElementById(&#x27;video&#x27;);&#xA; var player = new shaka.Player(video);&#xA; window.player = player;&#xA; player.addEventListener(&#x27;error&#x27;, onErrorEvent);&#xA; player.load(manifestUri).then(function() {&#xA; console.log(&#x27;The video has now been loaded!&#x27;);&#xA; }).catch(onError);&#xA; }&#xA; function onErrorEvent(event) {&#xA; onError(event.detail);&#xA; }&#xA; function onError(error) {&#xA; console.error(&#x27;Error code&#x27;, error.code, &#x27;object&#x27;, error);&#xA; }&#xA; document.addEventListener(&#x27;DOMContentLoaded&#x27;, initApp);&#xA; </script>

 
 
 
 







For some reason the stream is only playing the first chunk and never requesting for the next chunk. How can I make it load the next chunks?


When tried using dash.js I couldn't get it to load even the first chunk.


Thanks in advance.

Use variance metric for integral projection vector matchThis commit replaces the SAD with variance as metric for the
integral projection vector match. It improves the search accuracy
in the presence of slight light change. The average speed -6
compression performance for rtc set is improved by 1.7%. No speed
