La file d’attente de SPIPmotion
28 novembre 2010, parUne file d’attente stockée dans la base de donnée
Lors de son installation, SPIPmotion crée une nouvelle table dans la base de donnée intitulée spip_spipmotion_attentes.
Cette nouvelle table est constituée des champs suivants : id_spipmotion_attente, l’identifiant numérique unique de la tâche à traiter ; id_document, l’identifiant numérique du document original à encoder ; id_objet l’identifiant unique de l’objet auquel le document encodé devra être attaché automatiquement ; objet, le type d’objet auquel (...) -

Introducing Updates to the Funnels Feature
29 mai 2024, par ErinWe’ve made improvements to the Funnels feature to be more user-friendly and offer you greater flexibility.
<script type="text/javascript"><br />
if ('function' === typeof window.playMatomoVideo){<br />
window.playMatomoVideo("FunnelsProductUpdate2024", "#FunnelsProductUpdate2024")<br />
} else {<br />
document.addEventListener("DOMContentLoaded", function() { window.playMatomoVideo("FunnelsProductUpdate2024", "#FunnelsProductUpdate2024"); });<br />
}<br />
</script>Here’s what’s changing :
Setting up and managing funnels is now easier than ever
Previously, creating funnels was tedious and required going through the Goals feature. But we’ve changed that with the introduction of a separate page to configure funnels.
Create funnels with greater flexibility—no longer tied to goals
Funnels is now a standalone feature, providing you with more flexibility. Before, you could only create a funnel if it was tied to a goal, in other words, the final step in the funnel had to be a goal. What’s more, you also couldn’t use goals for steps in the funnel.
Previous configuration requirements of Funnels Now, funnels are independent of goals, and goals can serve as steps within the funnel. This means you have the freedom to configure any combination of steps in a funnel :
- All steps can be goals
- No steps need to be goals
- Or some steps can be goals, some steps can be events
No matter what your customer journey looks like, funnels now offer the versatility to meet your business’s specific needs.
Find friction points faster with intuitive visuals
One of the most significant improvements is the visual upgrade of the Funnels feature. The new Funnels graph is now visually in line with industry standards and intuitive.
The new visual provides a clearer view of your drop-off and conversion rates so you can instantly find points of friction in your funnel to improve the user experience and overall conversion rate.
This visualisation also provides a detailed overview of the number of visitors who enter, exit, skip, or proceed at each step of your funnel by using different coloured bars for visual clarity on each step’s performance.
With this update, we’ve also replaced ‘backfilled visits’ with ‘skipped steps’ to avoid misinterpretation of the data.
New data table for more granular insights
Accompanying this visual improvement is a new data table, allowing for more granular insights, segment comparison, and easy data export.
We’ve also increased Funnel analysis limits. You can now compare funnel data for 2 date periods and 6 segments (up to 12 compared datasets in total).

Discord bot stop playing music in random time of song
25 janvier 2021, par JusmejtrI have a discord to let me play a random song from the list.


How bot works :
Bot IS connected to firestore Cloud (firebase) where i have economy data from my server. Price for playing random song is 75 coins.


Everything worked as it should, but yesterday I used command, the bot started playing and after a while it stopped playing music and also no other commands worked, bot probably get freezed.


I have no errors in the console until after a minute it showed me this error.




The bot is hosted on Heroku and I also added this buildpack to ffmpeg in the settings.


https://github.com/jonathanong/heroku-buildpack-ffmpeg-latest


This is my code :


module.exports = {
 name: "buy-music",
 description: "buy a music",

 async execute(message, config, db){
 const PREFIX = (config.prefix);

 if(message.content === PREFIX + "buy music"){
 const ytdl = require("ytdl-core");
 message.delete();
 let uzivatel = message.author.tag;

 let voiceChannel = message.member.voice.channel;
 if(!voiceChannel) return message.reply("Musíš byť vo voice roomke");

 let cena = 75;
 
 db.collection('economy').doc(uzivatel).get().then(async (q) => {
 if(!q.exists) return message.reply("Nemáš vytvorený účet");
 var hodnota = q.data().money;
 if(hodnota < cena) return message.reply("Nemáš dostatok financií");

 db.collection('statusy').doc('music').get().then(async (asaj) => {
 let stav = asaj.data().stav;
 if(stav == "off"){
 db.collection('statusy').doc('music').update({
 "stav": "on",
 "autor": message.author.tag,
 });
 hodnota -= cena;
 db.collection('economy').doc(uzivatel).update({
 'money': hodnota
 });
 function randomhraj(){
 var pole = [
 My YT links

 ]
 let rnd = Math.floor(Math.random() * pole.length);
 let output = pole[rnd];
 return output;
 }
 
 try{
 var pripojenie = await voiceChannel.join();
 message.reply(`Úspešne si si kúpil chuťovečku`);
 }catch(error){
 console.log(`Error pri pripajani do room (music join) ${error}`);
 }
 
 const dispatcher = pripojenie.play(ytdl(randomhraj())).on("finish", async() => {
 await voiceChannel.leave();
 await db.collection('statusy').doc('music').update({
 "stav": "off",
 "autor": "nikto",
 });
 }).on("error", error => {
 console.log(error)
 })
 dispatcher.setVolumeLogarithmic(5 / 5)
 }else{
 message.reply("Momentálne si hudbu kúpil niekto iný alebo ak si hudbu kúpil a chceš ju zastaviť použi príkaz *stop");
 }
 
 });
 });
 
 }else if(message.content === PREFIX + "stop"){
 message.delete();
 db.collection('statusy').doc('music').get().then((n) => {
 let kto = n.data().autor;
 let meno = message.author.tag;
 if(!message.member.voice.channel) return message.channel.send("Musíš byť vo voice roomke pre stopnutie hudby");
 if(kto == meno){
 message.member.voice.channel.leave();
 message.channel.send("Úspešne odpojený");
 db.collection('statusy').doc('music').update({
 "stav": "off",
 "autor": "nikto",
 });
 }else{
 message.reply("Zastaviť hudbu môže len ten kto si ju kúpil");
 }
 });
 }

FFMpeg C++ encoder fails with hardware acceleration quick sync intel
28 août 2022, par tealsI am trying to debug an issue I have with a simple C++ encoder using FFMmpeg. The following code below works correctly on these other hardware acceleration systems/platforms :


- 

- Mac/VideoToolbox,
- Cuda/NVEnc
- Raspberry pi/h264_v4l2m2m.








It fails on intel quick sync at
avcodec_open2. I'm using Ubuntu 22.04. I built FFMpeg from source with the Intel Media SDK installed and configured. I verified that the QuickSync install works. I also have a corresponding decoder implementation that works correctly using intel quick sync. So I know everything properly installed. I am also running this on an 11th Gen Intel CPU.

[hevc_qsv @ 0x564b0d34f0c0] Low power mode is unsupported (This sometimes shows up)
[hevc_qsv @ 0x563691234000] some encoding parameters are not supported by the QSV runtime. Please double check the input parameters.
Error initializing output stream 0:0 -- Error while opening encoder for output stream #0:0 - maybe incorrect parameters such as bit_rate, rate, width or height


This is the only error that I get and I haven't found any helpful resources. I tried playing around with different parameters but nothing seems to work. Any help or insight would be extremely helpful.
