Other interesting software
13 avril 2011, parWe don’t claim to be the only ones doing what we do ... and especially not to assert claims to be the best either ... What we do, we just try to do it well and getting better ...
The following list represents softwares that tend to be more or less as MediaSPIP or that MediaSPIP tries more or less to do the same, whatever ...
We don’t know them, we didn’t try them, but you can take a peek.

How to log unconverted files in FFMPEG due to error ?
10 juillet 2017, par eugenemonI am converting 30,000 video files (each with different number of data/video/audio/subtitle streams) using a single batch file. I do not require data/subtitle streams. This is the code I am using for the batch file :
for %%i in (*.dat *.mpg *.mpeg) do ffmpeg -hide_banner -v info -n -i %%i -map 0 -dn -sn -c:v libx264 -crf 20 -c:a aac -b:a 192k "%%~ni.mp4" >> log.txt 2>&1
pauseThe resulting log file that I get is 1.67gb in file size and is extremely difficult for me to go through to find the errors of files that weren’t converted.
An example of a successfully converted file would look like this in the log file :
Input #0, mpeg, from '571317.mpg':

Announcing Long Term Support in Piwik 2 – The analytics platform for your mission critical projects
11 janvier 2016, par Matthieu Aubry — About, DevelopmentWe are proud to announce our Long Term Support (LTS) for Piwik 2.X !
Why Long Term Support (LTS) ?
Part of our mission is to ready Piwik for the enterprise — and ready the enterprise for Piwik. Our fast release cycle and our ability to quickly innovate has served us well for the past seven years and has lead Piwik to being one of the most popular open source projects, used by over one million websites worldwide. But Piwik’s success today has also shown us that this fast release cycle is not suited for all users and customers. Like most large open source projects (such as Ubuntu, Firefox, Debian, Symfony, Node.js, etc.) at Piwik we now also offer a Long Term Support release which gives users the confidence that Piwik can be used for mission critical projects for months to come.
What does LTS mean for Piwik ?
For the duration of the LTS period, Piwik 2.X will continue to receive the following fixes :
- Critical bugs causing data loss or data corruption.
- Major and Critical security issues.
Our goal is to offer you a Piwik LTS release that you can trust for all your mission critical projects.
How long will Piwik 2.X be supported ?
Piwik 2.X will be supported for at least 12 months after the initial release of Piwik 3.0.0.
Piwik 3.0.0 is expected to be released in the second half of 2016.
This means that Piwik 2.X will be supported at least until the second half of 2017.Which Piwik version is LTS ?
The latest Piwik 2.16.X release is our Long Term Support version.
How do I benefit from the LTS version ?
To get the full benefits of Piwik LTS, please make sure you are using the latest LTS version. First, update to the latest Piwik 2.X version, then Configure Piwik to use the LTS release channel and then update to the latest LTS version.
How do I configure Piwik to use the LTS version ?
By default, Piwik will not use the LTS version. When you use the one-click update your Piwik instance will be updated to the very latest release : when Piwik 3.0.0 will be released, the one click update will update your instance to 3.0.0. It is however possible to configure your Piwik so that you will stay on Piwik 2.X and keep using the LTS Long Term Support version :
- Login Piwik as the Super User,
- Go to Settings > General > Update settings,
- Under “Release channel” click “Latest stable 2.X Long Term Support version”, and click “Save”.
How do I get professional Piwik Support ?
If you need professional support for your Piwik service get in touch with the Piwik PRO experts.
For other questions, feedback or discussion, feel free to join our forums and comment on this LTS forum post.
We wish you all a fantastic year 2016 !

Is there a way to use external filters in ffmpeg ?
26 octobre 2017, par EduardoI want to write a filter that is saved to a shared object or independent executable that can be used as any other ffmpeg filter.
I am using the architecture described here : http://nullprogram.com/blog/2017/07/02/ but it is not ideal as it is not integrated and I have to specify the framerate (even if I am not changing it) in the encoder after the filter has been aplied.
