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.

Why does ffmpeg keep using more and more RAM and crash ?
29 décembre 2022, par József Márton KakasI am using the following command with ffmpeg to encode a video file using the libsvtav1 codec :
ffmpeg -i hevc.mkv -map 0:v:0 -c:v:0 libsvtav1 -preset 8 -crf 22 -format matroska av1.mkv
.

However, ffmpeg is using up all of my available RAM and crashing. I have also tried using the libx264 codec, but the same issue occurs, although it happens more slowly. I have already allocated 12 GB of RAM to ffmpeg, but it still seems to be insufficient. How can I prevent ffmpeg from using all of my available RAM and crashing when using either the libsvtav1 or libx264 codecs ?


I have tried it on another VM, but the same issue occurs. Here is the full output of the program.

MPV -when playing two identical rtsp streams at the same time, one of them stops playing
15 novembre 2022, par xzf361I utilize mpv to play rtsp stream, when I execute the following command for the first time, rtsp plays fine.
mpv rtsp ://192.168.1.217:554/stream1
When I execute the same command above for the second time, the first playback window will stop playing, but the second playback window will play normally.
why is that ?
