Automated installation script of MediaSPIP
25 avril 2011, parTo overcome the difficulties mainly due to the installation of server side software dependencies, an "all-in-one" installation script written in bash was created to facilitate this step on a server with a compatible Linux distribution.
You must have access to your server via SSH and a root account to use it, which will install the dependencies. Contact your provider if you do not have that.
The documentation of the use of this installation script is available here.

Creating a transparent video out of an input video
28 juillet 2021, par poldownI'm trying to create a video with a transparent background out of an input video (with the same dimensions, etc.). I tried several strategies (using the
chromakey
filter and others) and none worked... I got this far :

ffmpeg -i input.mp4 -filter_complex "color=color=black@0.0,format=yuva420p[bg],[bg][0:v]scale2ref[bg][0v],[bg]drawbox=x=10:y=10:w=100:h=100:color=pink@0.5;[0v]nullsink" -c:v qtrle -an "alpha.mov"



- 

- creating a video stream with transparency, and setting a transparent background (black@0.0)
- scaling the transparent video according to the input video
- [for testing purposes : drawing a box over the transparent video. I omitted the part in which I embed subtitles onto the video, for simplicity's sake]
- discarding the input video stream
- removing the audio stream












It basically works, but the processing never ends - I can't manage to limit the output video length so it'll match the input video's length...
I've tried using the
-shortest
option anywhere in the command - with no success.

Give a video rounded transparent edges so that it can be overlayed on another video using FFMPEG
15 octobre 2020, par Kevin JastiIm trying to overlay a smaller video (200x200)on top of a bigger video (800x800).



I've used the FFMPEG overlay filter to achieve this



ffmpeg -i big.mp4 -vf "movie=small.mkv[clip2]; [in][clip2] overlay=1:5 [out]" final.mp4




Challenge is that the smaller video needs its edges to be rounded.
I have tried working with alphaextract and alphamerge. The documentation on FFMPEG is sparse and im not sure how to go about it.
