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.

(no accepted answer) How to merge 2 overlapping videos into one video using ffmpeg or opencv ?
3 janvier 2021, par Muhammad UmerMerging two videos is easy, been answered couple of times. What I have is multiple overlapping videos. A video might have overlaps with video before it. Meaning if video 1 covers 1-5 timeline then video 2 may overlap 1, and cover 3 to 8. Merging them as is would result in 1-5|3-8, when i need 1-8 only.



Videos are alphabetically sorted.



My general idea of solution is...



- 

- grab last frame of the video
- if it's first video continue
- if it's not first video, ie. 2nd, search for frame saved in previous steps frame by frame
- if it reaches to last frame of current video then there is no overlap continue
- if it founds a frame then clip 2nd video up to that frame inclusive and then go to next frame
- once all videos have been analyzed, merge them into one video.















I need to translate this to ffmpeg commands. Or opencv if that's a better tool.



If there is better way of doing that, I'm interested in that too.

This information could be omitted.

But it becomes quite important for correctness of GPS Data stored in Stream #2.

Unfortunately, all the settings I have tried for FFMPEG, do not preserve the duration of Stream #2.
& the output ends up looking like this :

Any ideas how to preserve that real time duration indicator ?

Requirements for using ffmpeg to create mpeg4 files in SaaS solution
25 août 2016, par Paul FlemingMy requirement is :
On upload of a supported video file, convert the file to common formats to maximize web compatibility.
Essentially, I want to take a non-web-supported video file, and converted it to WEBM and MPEG4. This will take place on a Windows Server VM inside Microsoft Azure.
ffmpeg seems to be the de facto standard for video conversion yet it introduces licensing hell, not only with GPL/LGPL but by not offering a commercial license, meaning I now have to worry about paying royalties to MPEG-LA.
Can anyone advise on MPEG-LAs licensing model as it applies to SaaS ? I will not be distributing ffmpeg (runs server side) and the conversion takes place on Windows (Server) OS.
