Ajouter notes et légendes aux images
7 février 2011, parPour pouvoir ajouter notes et légendes aux images, la première étape est d’installer le plugin "Légendes".
Une fois le plugin activé, vous pouvez le configurer dans l’espace de configuration afin de modifier les droits de création / modification et de suppression des notes. Par défaut seuls les administrateurs du site peuvent ajouter des notes aux images.

Mediabox : ouvrir les images dans l’espace maximal pour l’utilisateur
8 février 2011, parLa visualisation des images est restreinte par la largeur accordée par le design du site (dépendant du thème utilisé). Elles sont donc visibles sous un format réduit. Afin de profiter de l’ensemble de la place disponible sur l’écran de l’utilisateur, il est possible d’ajouter une fonctionnalité d’affichage de l’image dans une boite multimedia apparaissant au dessus du reste du contenu.
Pour ce faire il est nécessaire d’installer le plugin "Mediabox".

ffmpeg produces "is_avc" = false with h264_nvenc & tee muxer
14 août 2018, par Areeb111I am using ffmpeg for encoding MKV (Matroska Video files) to 2x MP4 (H264 - 720p Main@L4) & (H264 - 360p Baseline@L3.1).
Having really strange problem when using
-c:v h264_nvenc
andtee muxer
then the produced output file is havingis_avc=false
even i have checked the same input matroska file with another server running with Intel QuickSync-c:v h264_qsv
with the same command then the produced output file isis_avc=true
.The main goal that i want the
is_avc=true
is because the files must be played usingnginx-vod-module
which requires the AVC video format to be streamed.Steps to reproduce the problem :
- Custom ffmpeg build with NVENC support
ffmpeg version N-91182-gbdf1bbd Copyright (c) 2000-2018 the FFmpeg developers built with gcc 4.8.5 (GCC) 20150623 (Red Hat 4.8.5-28)
- ffprobe
version 4.0.2-static https://johnvansickle.com/ffmpeg/ Copyright (c) 2007-2018 the FFmpeg developers
- Running ffmpeg command line with NVENC and tee muxer
/root/ffmpeg -y -t 00:00:50 -i "testinput.mkv" -filter_complex "[0:v]split=2[s0][s1];[s0]scale=-2:720[v0];[s1]scale=-2:360[v1]" -map "[v0]" -map "[v1]" -map 0:a -c:v h264_nvenc -b:v:0 1100k -b:v:1 600k -profile:v:0 main -profile:v:1 baseline -level:v:0 4 -level:v:1 3.1 -ac 2 -c:a aac -b:a 128k -af "aresample=async=1000:first_pts=0" -f tee "[select=\'v:0,a\']testoutput.mp4|[select=\'v:1,a\']testoutput-360.mp4"
- Running ffprobe for the output file to check "is_avc" :
./ffprobe -v quiet -print_format json -show_format -show_streams testoutput.mp4
-
My current ffprobe output results are :
./ffprobe -v quiet -print_format json -show_format -show_streams testoutput.mp4

Syntax error : "(" unexpected — with !(*.sh) in bash script [duplicate]
25 janvier 2023, par Jmv JmvI want to run a sh file :



#!/bin/bash
for f in !(*.sh); do
 ffmpeg -i "$f" -vf yadif=0:-1 -threads 0 -c:v libx264 -pix_fmt yuv420p \
 -r 29.97 -b:v 3000k -s 1280x720 -preset:v slow -profile:v Main \
 -level 3.1 -bf 2 -movflags faststart /mnt/media/out-mp4/"${f%.mxf}.mp4"
 rm $f
done




However, I get the following error :



2: task1.sh: Syntax error: "(" unexpected




If I try directly on the command line it works perfectly.





the path and permissions are already reviewed





Any idea what might be happening ?
