Possibilité de déploiement en ferme
12 avril 2011, parMediaSPIP peut être installé comme une ferme, avec un seul "noyau" hébergé sur un serveur dédié et utilisé par une multitude de sites différents.
Cela permet, par exemple : de pouvoir partager les frais de mise en œuvre entre plusieurs projets / individus ; de pouvoir déployer rapidement une multitude de sites uniques ; d’éviter d’avoir à mettre l’ensemble des créations dans un fourre-tout numérique comme c’est le cas pour les grandes plate-formes tout public disséminées sur le (...) -
Ajouter des informations spécifiques aux utilisateurs et autres modifications de comportement liées aux auteurs
12 avril 2011, parLa manière la plus simple d’ajouter des informations aux auteurs est d’installer le plugin Inscription3. Il permet également de modifier certains comportements liés aux utilisateurs (référez-vous à sa documentation pour plus d’informations).

How to merge mp4 audio dash fragment with another audio
18 mars 2019, par mosvovI have 1 audio file from dash stream
Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'file_191282-377206_header.mp4': Metadata:
major_brand : iso6
minor_version : 1
compatible_brands: mp42dashmsdhmsixiso6avc1isom
creation_time : 2016-04-29T11:04:26.000000Z Duration: 00:00:30.02, start: 14.997333, bitrate: 49 kb/s
Stream #0:0(eng): Audio: aac (LC) (mp4a / 0x6134706D), 48000 Hz, stereo, fltp, 48 kb/s (default)Also in exiftool output :
Movie Data Size : 180193
Movie Data Offset : 6388I try to merge with another audio and save metadata info like Movie Data Size/Offset and start/duration time.
I try with ffmpeg/MP4Box commands like :MP4Box -new -add file_191282-377206_header.mp4 -add out000.mp4
ffmpeg -i file_191282-377206_header.mp4 -i out000.mp4 -codec copy -shortest output.mp4
ffmpeg -i file_191282-377206_header.mp4 -i out000.mp4 -filter_complex amerge -ac 2 -c:a aac output.mp4All the time information erased or changed.
So question is how to merge 2 audio files inside mp4 and not change Movie Size/Offset and start/duration time ?

WebM live streaming via DASH
