Ces scripts sont installés automatiquement par le script d’installation automatique si une installation de munin est détectée.

How to download/convert multiple streams to multiple outputs with FFmpeg ?
16 avril 2016, par Website NewbieLet’s say I have 20 different online stream videos (playlist.m3u8) and I want every video to output to their own .avi files. How can I do that in single file, so I don’t have to download and convert every single one separately ?
I found a -map command online, but didn’t get straight answer to this.
Will this be a working code ?
ffmpeg -i 1playlist.m3u8 -vf scale=768:-1 -vcodec libx264 -crf 24 -acodec copy -map 0 1.avi \
-i 2playlist.m3u8 -vf scale=768:-1 -vcodec libx264 -crf 24 -acodec copy -map 1 2.avi \
-i 3playlist.m3u8 -vf scale=768:-1 -vcodec libx264 -crf 24 -acodec copy -map 2 3.avi -
Download only a part of the video in the server
19 août 2013, par whiteletters and blankspacesI am building a web application for creating animated gif from youtube videos. These animated gifs will be fews seconds long, but may come from very long videos hosted in Youtube.
After reading and reading, It looks like I should first download the whole video in server, then cut the required part, ( probably convert it), then process it to generate the gif using ffmpeg for example.
Could you please tell me :
Does the whole video should be necessarly downloaded in server ? Or there is a way to ask my server and Youtube Server to exchange only the requested (very small) part of the video ? I think that downloading the whole video will result in bad resources usage, especially in concurrency environnement which will affect performance in my one-server infrascrucure.
What are the alternatives of downloading the video (or part of video) to achieve such goal ? Is there a client side solution for storing data and using similar ffmpeg functionalities ?
