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 (...) -

MOV to ACVHD conversion via Spring Boot and FFmpeg leads to file system error
31 décembre 2024, par epicUsernameI am experiencing an issue on a personal project that seeks to convert HEIC to JPG files and MOV files to AVCHD format. The HEIC to JPG conversion works, but the MOV to AVCHD does not, which is where my problems lie.


The intent is to do this with Spring Boot and FFmpeg, using a simple interface done in WindowBuilder.


The relevant bits are the pom file :

A few caveats :


- 

-
I did explore FFmpeg and GStreamer for this project. GStreamer was inconclusive, with available version for it that were too old for use with my current state of STS4.27 and Java 17, even if this version of Java is under long-term support...


-
I've used AI to tell me about the options and suggest ways to build this thing, since multimedia handling is very far away from my skillset. I don't have a good conceptual grasp of video formats and how they transfrom from one to another.








The issue, as I have identified it, occurs at these lines :


// Ensure the destination file is writable
 if (!destinationFile.canWrite()) {
 JOptionPane.showMessageDialog(null, "Output file is not writable.", "File Error", JOptionPane.ERROR_MESSAGE);
 return;
 }


^^ And this, while temporarily commented out for testing, it meant to compensate for an issue that occurs here in the conversion function :


if ((outputFormatContext.oformat().flags() & avformat.AVFMT_NOFILE) == 0) {
 // Ensure the output path has the correct extension
 String outputPath = destinationFile.getAbsolutePath().replace("\\", "/") + ".avchd";
 System.out.println("Normalized output path: " + outputPath);

 // Try opening the output file
 int ret = avformat.avio_open(outputFormatContext.pb(), outputPath, avformat.AVIO_FLAG_WRITE);
 if (ret < 0) {
 BytePointer errorBuffer = new BytePointer(avutil.AV_ERROR_MAX_STRING_SIZE);
 avutil.av_strerror(ret, errorBuffer, errorBuffer.capacity());
 System.out.println("Failed to open output file: " + errorBuffer.getString());
 return;
 }
 }


The idea here is that the avio_open() function requires the use of the a valid file path that it can open to be able to write it.


Padadoxically, the file conversion seems to work, but the project crashes with a fatal error in the console :

If anyone has a perspective on this, it'd be appreciated.


The catch 22 in this project is that pre-creating the file is not a good idea, since avio_open has a purpose in-built method for that (I tried). Error checking everything about Java's File class in terms of setting pathways and creating and deleting files is not problematic. Likewise, permissions are all fine (Full Control in source and target folders) ; I've tested default C drive folders, which have restritions, to a separate volume and removable media, to no effect. Likewise, FFmpeg requires a forward slash, "/" in file paths, whereas Java does the backslash, generally. That's been handled with the replace method in the above conditioning, also to no effect.


The basic contradiction in the project seems to be that the error tries open a file that does not exist, with a valid source and destination file, and if I try to create a placeholder file wiht an acvhd extension at the event handling for the Convert button, it still errors out ; meanwhile, FFmpeg allegedly handles the file creation at its core, but requires a valid path to be passed ; I've tried with and without a filename, with and without an extension. I'm not able to resovle it.


The excessive error handling conditions are in an effort to isolate the problem, which I think I've done.


There also seems to be a compatibility between mpegts and acvhd, which is why I also had that format specified in the conversion function, without result.


I also have the idea to be able to do this without having to install any libraries locally or having to set path variables, which is an aspect that both GStreamer and FFmpeg have.


Nearest suggestion I've found is this : integrate ffmpeg with spring boot


AI remains hopeless for resolving this issue.

15 octobre 2019, par Matomo Core Team — CommunitySelf-hosting web analytics got a whole lot easier ! Introducing Matomo for WordPress
Be the first to try it out ! Your feedback is much needed and appreciated
Get a fully functioning Matomo (which is comparable to Google Analytics) in seconds ! How ? With the new Matomo Analytics for WordPress plugin.
Web analytics in WordPress has never been easier to get, or more powerful. Matomo Analytics for WordPress is the one-stop problem solver. It’ll save you time, money and give you the insights to help your website or business succeed.
Best of all, we get to further the goal of decentralising the internet. Our hope is for Matomo Analytics for WordPress to spread far and wide. We’re so excited that more and more people can now get their hands on this powerful, free, open-source analytics platform, in a few clicks !
Download now and check it out !
What do you get ?
- No more signing up to third party analytics service (like Google)
- No more sending away your valuable data to a third party service (like Google)
- Easy setup – install with a few clicks, no tracking code installation or developer knowledge needed
- 100% accurate data – no data sampling and no data limits
- Full data ownership – all data is stored on your servers and no one else can see your data

- Powerful features – segmenting, comparing reports, different visualisations, real-time reports, visit logs and visitor profiles, Matomo Tag Manager, dashboards, data export, APIs, and many more
- Compared to other WordPress solutions we don’t charge you extra for basic features that should work out-of-the-box
- Just like Matomo On-Premise, Matomo Analytics for WordPress is free
We need your feedback !
We all know and love the versatility of WordPress – with over 55,000 plugins and all the different ways of hosting it. However, with this great versatility comes the potential for things to be missed, so we’re keen to hear your feedback.
- Is our plugin breaking anything on your WordPress, or, not compatible with something ? Please create an issue on our repository.
- Is something not working ? If so, what ? Please create an issue on our repository.
- How does running Matomo impact the performance of your WordPress server ? Also, if you have any other feedback for us – whether good or bad – please email us at wordpress@matomo.org. We’d love to hear what you think !
- Can you perform a security review of the plugin ? Security issues are best reported to security@matomo.org
- Do you have any questions ? Questions are best asked in our forum
Thank you ! We really appreciate your help on this ❤️
How do you get Matomo Analytics for WordPress ?
Log in to your WordPress and go to “Plugins => Add New”, search for “Matomo Analytics – Ethical Stats. Powerful Insights”, click on “Install” and then “Activate”.
All you need is at least WordPress 4.8 and PHP 7.0 or later. MySQL 5.1+ is recommended.
The source code is available at : https://github.com/matomo-org/wp-matomo/.
In perfect harmony : Matomo and WordPress
The idea for this started two years ago when we realised the similarities between the Matomo and WordPress project.
Not only from a technological point of view – where both are based on PHP and MySQL and can be extended using plugins – but also from a philosophical, license and values point of view. We both believe in privacy, security, data ownership, openness, transparency, having things working out-of-the-box, simplicity etc.
WordPress is currently used on approximately 30% of all websites. Many of them use the self-hosted open-source WordPress version. Giving everyone in this market the opportunity to easily get a powerful web analytics platform for free, means a lot to us. We believe WordPress users get a real choice besides the standard solution of Google Analytics, and it furthers our effort and goal of decentralising the internet.
We’re hoping more people will be empowered to protect user privacy, have access to a great free and open-source tool, and keep control of data in their own hands.
We hope you feel the same. Help us spread the word to your friends and get them in on this awesome new project !

Isn’t there already a WP-Matomo plugin for WordPress available ?
Yes, the existing WP-Matomo (WP-Piwik) plugin is an awesome plugin to connect your existing Matomo On-Premise or Matomo Cloud account with WordPress. The difference is that this new plugin installs Matomo Analytics fully in your WordPress. So you get the convenience of having a powerful analytics platform within your WordPress.
We highly recommend you install this new plugin if you use WordPress and are not running Matomo yet.
If you are already using Matomo on our Cloud or On-Premise, we’d still highly recommend you use WP-Matomo (WP-Piwik). So that you get an easier way of inserting the tracking code into your WordPress site and get insights faster.
I have a high traffic website, will it be an issue ?
If you have a lot of traffic, we’d advise you to install Matomo On-Premise separately. There’s no specific traffic threshold we can give you on when it’s better to use Matomo On-Premise. It really depends on your server.
We reckon if you have more than 500,000 page views a month, you may want to think about using Matomo On-Premise with WP-Matomo instead, but this is just an estimate. In general, if the load on your server is already quite high, then it might be better to install Matomo on a separate server. See also recommended server sizing for running Matomo.
How do I report a bug or request a new feature in Matomo for WordPress ?
Please create an issue, on our repository whenever you find a bug or if you have any suggestion or ideas of improvement. We want to build an outstanding analytics experience for WordPress !
Have another question you’re dying to ask ? The Matomo for WordPress FAQ page might have the answer you need.

How do you get Matomo Analytics for WordPress ?
You can then upload it in your WordPress by going to “Plugins => Add New”. During the upload, if you get an error like “Are you sure you want to do this ?”, we recommend you upload the extracted zip file on to your server and into your ‘wp-content/plugins’ folder manually using ftp or ssh. Make sure the plugin name is ‘matomo’.
All you need is at least WordPress 4.8 and PHP 7.0 or later. MySQL 5.1+ is recommended.

Not only from a technological point of view – where both are based on PHP and MySQL and can be extended using plugins – but also from a philosophical, license and values point of view. We both believe in privacy, security, data ownership, openness, transparency, having things working out-of-the-box, simplicity etc.
WordPress is currently used on approximately 30% of all websites. Many of them use the self-hosted open-source WordPress version. Giving everyone in this market the opportunity to easily get a powerful web analytics platform for free, means a lot to us. We believe WordPress users get a real choice besides the standard solution of Google Analytics, and it furthers our effort and goal of decentralising the internet.
We’re hoping more people will be empowered to protect user privacy, have access to a great free and open-source tool, and keep control of data in their own hands.
We hope you feel the same. Help us spread the word to your friends and get them in on this awesome new project !

Isn’t there already a WP-Matomo plugin for WordPress available ?
Yes, the existing WP-Matomo (WP-Piwik) plugin is an awesome plugin to connect your existing Matomo On-Premise or Matomo Cloud account with WordPress. The difference is that this new plugin installs Matomo Analytics fully in your WordPress. So you get the convenience of having a powerful analytics platform within your WordPress.
We highly recommend you install this new plugin if you use WordPress and are not running Matomo yet.
If you are already using Matomo on our Cloud or On-Premise, we’d still highly recommend you use WP-Matomo (WP-Piwik). So that you get an easier way of inserting the tracking code into your WordPress site and get insights faster.
I have a high traffic website, will it be an issue ?
If you have a lot of traffic, we’d advise you to install Matomo On-Premise separately. There’s no specific traffic threshold we can give you on when it’s better to use Matomo On-Premise. It really depends on your server.
We reckon if you have more than 500,000 page views a month, you may want to think about using Matomo On-Premise with WP-Matomo instead, but this is just an estimate. In general, if the load on your server is already quite high, then it might be better to install Matomo on a separate server. See also recommended server sizing for running Matomo.
How do I report a bug or request a new feature in Matomo for WordPress ?
Please create an issue, on our repository whenever you find a bug or if you have any suggestion or ideas of improvement. We want to build an outstanding analytics experience for WordPress !
Have another question you’re dying to ask ? The Matomo for WordPress FAQ page might have the answer you need.
