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) (...)

Cannot Play Video Output of Libavcodec (ffmpeg) Encoding Example
29 octobre 2019, par user3707763From FFMPEG’s GitHub, I use the
encode_video.c
to generate a 1 second video. Here is the example in question : https://github.com/FFmpeg/FFmpeg/blob/master/doc/examples/encode_video.cI compile with :
gcc -Wall -o ffencode encode_video.c -lavcodec -lavutil -lz -lm
Clean compile, zero warnings.
I test the program by running :
./ffencode video.mp4 libx264
Lots of stats printed out (expected based on source code) as well as ffmpeg logs, but ultimately no errors or warnings.
However, then the generated output
video.mp4
, can only be played byffplay
, and VLC Player (as well as Google Chrome) fail to play the video.Playing it via
vlc
command line actually prints :[00007ffd3550fec0] main libvlc: Running vlc with the default interface. Use 'cvlc' to use vlc without interface.

how to build built-in video editor using HTML, CSS, JS ? [closed]
29 avril 2021, par Ayca SolmazI'm trying to build a website with a built in video editor where the user would upload a video and the video would just show up on the video editor and from there they can trim the video (let's say from 1:24-2:30)


I have basic knowledge on FFMPEG but I was looking for a way to do this with Javascript. I have a slider where you can select a range, it's just the trimming part I'm struggling with. I have set up UI's as well where there're two sliders to select the range and a trim button. I'd appreciate any help at this point.
