Support de tous types de médias
10 avril 2011Contrairement à beaucoup de logiciels et autres plate-formes modernes de partage de documents, MediaSPIP a l’ambition de gérer un maximum de formats de documents différents qu’ils soient de type : images (png, gif, jpg, bmp et autres...) ; audio (MP3, Ogg, Wav et autres...) ; vidéo (Avi, MP4, Ogv, mpg, mov, wmv et autres...) ; contenu textuel, code ou autres (open office, microsoft office (tableur, présentation), web (html, css), LaTeX, Google Earth) (...)

Data Privacy in Business : A Risk Leading to Major Opportunities

FFMPEG does not add images to audio
20 février 2018, par GooglebotI want to create a slideshow with a background music by
ffmpeg
, and use the commandffmpeg -f concat -safe 0 -i map.txt -i audio.flac -vsync vfr -pix_fmt yuv420p -strict -2 video.mp4
and map.txt is like
file '1.jpg'
duration 15
file '2.jpg'
duration 60The result is a video with the audio and blank background. If I run the above command without audio as
ffmpeg -f concat -safe 0 -i map.txt -pix_fmt yuv420p -strict -2 video.mp4
a perfect video of the images (the intended slideshow) is generated (but obviously without audio).
I reckon the problem is related to synchronising the audio and images.
This is the terminal output for the first command
ffmpeg -f concat -safe 0 -i map.txt -i audio.flac -vsync vfr -pix_fmt yuv420p -strict -2 video.mp4

How to keep transparency when scale webm file with ffmpeg
5 octobre 2022, par Sonia KidmanI'm using ffmpeg to scale my WEBM file, by using below command : 
ffmpeg -i in.webm -c:v libvpx -vf scale=100:100 out.webm
The output has correct resolution as I expected but the problem is transparency become black background.



Could someone give me a solution for this.



Thank you so much.
