La sauvegarde automatique de canaux SPIP
1er avril 2010, parDans le cadre de la mise en place d’une plateforme ouverte, il est important pour les hébergeurs de pouvoir disposer de sauvegardes assez régulières pour parer à tout problème éventuel.
Pour réaliser cette tâche on se base sur deux plugins SPIP : Saveauto qui permet une sauvegarde régulière de la base de donnée sous la forme d’un dump mysql (utilisable dans phpmyadmin) mes_fichiers_2 qui permet de réaliser une archive au format zip des données importantes du site (les documents, les éléments (...) -

libavformat/dashdec : Support negative value of the @r attrbute of S in SegmentTimelin...
13 août 2018, par sanillibavformat/dashdec : Support negative value of the @r attrbute of S in SegmentTimeline element.
The following patch supports parsing negative value of the @r attribute of S in SegmentTimeline element.
Example streams :

FFMpeg command line to create specific MPD Manifest
22 février 2024, par Seth HabermanI have tried to get an FFMpeg command to yield the below manifest. Right below is the FFmpeg command that I have tried to make but it has not created the same manifest file as what I am trying to replicate a stream from a third party system to add my own stream to their system so that it will actually play back.


"$ffmpeg_path" \
 -i "$input_file" \
 -r 30000/1001 \
 -vf "scale=3840:1080" \
 -c:v libx265 \
 -c:a aac -b:a 128k \
 -ar 48000 \
 -f dash \
 -use_timeline 1 \
 -use_template 1 \
 -init_seg_name "init-stream\$RepresentationID\$.m4s" \
 -media_seg_name "chunk-stream\$RepresentationID\$-\$Number%05d\$.m4s" \
 -seg_duration 3 \
 "$output_file"


The code above yields a manifest that is structured like below.


<?xml version="1.0" encoding="utf-8"?>

The problem is that I I need it to create a stream where the manifest looks like the manifest below. If it doesn't look or function as below, it will not playback correctly on this third parties system.
