Multilang : améliorer l’interface pour les blocs multilingues
18 février 2011, parMultilang est un plugin supplémentaire qui n’est pas activé par défaut lors de l’initialisation de MediaSPIP.
Après son activation, une préconfiguration est mise en place automatiquement par MediaSPIP init permettant à la nouvelle fonctionnalité d’être automatiquement opérationnelle. Il n’est donc pas obligatoire de passer par une étape de configuration pour cela. -

While transcoding to mpegts ffmpeg creates the first frame after 1.48 seconds delay
15 mars 2018, par Biraj B ChoudhuryI have transcoded a file to mpegts using the following command
./ffmpeg -y -i big_buck_bunny_720p_5mb.mp4 -vcodec libx264 -x264opts "keyint=48:min-keyint=48:no_scenecut" -r 23.976 -c:a copy -f mpegts test.mpegts
When I run ffprobe on it -
./ffprobe -i test.mpegts -select_streams v -show_frames -of csv
I see that the first frame starts at 1.48 seconds why is this so ?

And now I get the following in ffprobe

The first frame is at 0.000 when the output is mp4 so this is something particular to mpegts.

We are hiring engineers to build an awesome product and platform used by millions of people
16 février 2016, par Piwik Core Team — UncategorizedAre you ready for a new challenge ? Or maybe you know someone who is looking for a change ? We have some exciting problems to solve and are looking for senior developers to work with us and our community on our open source Piwik Analytics platform. Piwik is used by more than one million websites all over the world. It is deployed on more than 300.000 servers and some users track more than 1 billion actions per month.
What is it like to work on Piwik ?
We develop this software using modern PHP, MySQL, Redis, AngularJS and more. We provide several kind of APIs and a plugin architecture to allow developers to extend and change Piwik to their needs. However, we would not be Piwik if we stopped at this point ! We want to turn Piwik into an even more awesome product and platform.
You can imagine there is a lot to do and many challenges to face !While one part is to always make Piwik scale better and to improve UI and UX, we also want to provide simple APIs to make the life of developers as pleasant as possible. We aim to solve things the right way and our thousands of unit, integration, system, JavaScript and screenshot tests help us to innovate and to not be afraid of change. We like clean code and constant improvements.
The Piwik team lives in New Zealand and Europe (Germany). We do the vast majority of our collaboration online. Our values include being open, transparent and sharing knowledge. For this we use tools like GitHub and Slack to communicate and Quake servers to take our minds off complex challenges. We are a small, flexible team, so when you come aboard, you will play an integral part in engineering and have a big impact on the product loved by so many people. You’ll help to create a welcoming environment for new contributors and set an example with your development practices and communications skills.
Apply now, or spread the word !
If you have strong skills in PHP send us an email with your CV and tell us a little about yourself and your experience in engineering complex applications.
Apply for a job here http://piwik.org/jobs/ and if you’re maybe not the right candidate, contribute to the project by sharing this blog post and by sending it to your friends !
