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.

Reduce ffmpeg CPU usage with h265 [closed]
23 septembre 2024, par NeskelogthI have a video file to convert using
ffmpeg
on Ubuntu 22.04. The input uses the codech264
and I want to convert it toh265
(mainly for storage capacity reasons). The output offfmpeg -version
is

ffmpeg version N-113725-g37702e2066 Copyright (c) 2000-2024 the FFmpeg developers

I saw online that one of the options of
ffmpeg
is-threads
, but apparently it does not work, since usingffmpeg -i input.mp4 -c:v libx265 -c:a copy output.mp4
andffmpeg -i input.mp4 -c:v libx265 -c:a copy -threads 2 output.mp4
seem to be exactly the same in terms of CPU usage as shown byhtop
. Is there something wrong in my usage of-threads
?

ffmpeg does not respect the -t option and keeps recording [closed]
21 juillet 2024, par Naman MuleyThe command I use is :


ffmpeg -f avfoundation -framerate 30 -i "2:0" -vcodec libx264 -pix_fmt yuv420p -acodec aac -strict experimental -t 10 ./recordings/tmp.mp4



With the above command, I expect the recording output to stop after 10 seconds. But the ffmpeg command keeps running and does not stop.
Feels like I am missing something basic but I have now spent 3 hours debugging and cannot figure out why.


Usecase :
I need to record my screen's video as well as audio for a specifiable amount of time.


According to the manual, putting
-t
before-i
limits the input recording and putting it after-i
limits the output recording. I believe after the-i
is the correct way to go.

- 

- I tried using different codecs and pix_fmt options.
- Tried moving the
-t
before the-i
option and after. no change.






Works with only audio input :
The below command that records only the audio works out just fine.


ffmpeg -f avfoundation -i ":0" -acodec libmp3lame -t 10 ./recordings/tmp.mp3
