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.

How to use FFmpeg and GeForce Hardware to decode and encode 4K MKV movie to 1080p [closed]
27 janvier 2023, par slyfox1186I am struggling with the instruction provided to convert a 4k Movie to 1080p so I can run it easier on my plex server.


I have a Geforce 1080Ti and have enable cuda and all the necessary options when building ffmpeg.


I keep getting a weird error and I am stuck at the below point.


Here is my code that I am working on currently


REM @ECHO OFF
SETLOCAL ENABLEDELAYEDEXPANSION
COLOR 0A
TITLE CONVERT 4K TO 1080P USING GEFORCE HW

PUSHD "%~dp0"

SET "FF=C:\MAB\local64\bin-video\ffmpeg.exe"

FOR /R %%G IN (*.mkv) DO (
 "%FF%" -hide_banner -hwaccel cuda -y -i "%%~dpnG.mkv" -c:v h264_nvenc -preset slow -pix_fmts yuv420p10le -vf scale='1920:-1' -c:a copy "%%~dpnG(1080p).mkv"
 )

ECHO.
PAUSE
EXIT



below is the error output I get when running the above command

Maximize FFMpeg performance
23 octobre 2020, par DudeI'm trying to copy the video and convert the audio to EAC3 while dropping the subs, so I'm using this command


E:\ffmpeg\ffmpeg.exe -y -i "E:\source.mkv" -map 0 -vcodec copy -threads 6 -sn -acodec eac3 -b:a 640k -metadata:s:a:0 title="EAC3 5.1" "E:\destination.mkv"


but on my Windows 10 6-core i7 (3.5GHz) it's only outputting an average of 13x, 295 FPS, while CPU utilization is at 15%. How can this be improved so I can get closer to 100% CPU utilization ?

dca : change the core to work with integer coefficients.
17 décembre 2015, par Alexandra Hájkovádca : change the core to work with integer coefficients.
The DCA core decoder converts integer coefficients read from the
bitstream to floats just after reading them (along with dequantization).
All the other steps of the audio reconstruction are done with floats
which makes the output for the DTS lossless extension (XLL)
actually lossy.
This patch changes the DCA core to work with integer coefficients
until QMF. At this point the integer coefficients are converted to floats.
The coefficients for the LFE channel (lfe_data) are not touched.
This is the first step for the really lossless XLL decoding.
