  • La sauvegarde automatique de canaux SPIP

    1er avril 2010, par

    Dans 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 (...)

  • Automated installation script of MediaSPIP

    25 avril 2011, par

    To 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.

  • x264 Downsides of a high CRF (22) intermediary codec between conversions instead of lossless

    18 décembre 2019, par bobtheencoder

    I have a huge collection of video files that are in the range of CRF 16-20 taking up TB’s of space. The only need I have for these originals is that I have to encode them from time to time but the CRF of these final encodes is very low (CRF 26-28).

    I understand that a lossy to lossy converstion ALWAYS results in some quality loss but my question is what if the intermediate file is almost visually lossless compared to the final output.

    So to sum up, what quality difference should I expect from the following routes ?

    CRF 18 (original) -----> CRF 28 (final)
    
CRF 18 (original) -----> CRF 22 (long-term storage) -----> Lossy  CRF 28 (final)

  • Failing to push mpeg dash segment to webdav server using method PUT

    18 avril 2020, par Safwan Sada

    I am trying to push mpeg dash segments to webdav server.

    



    Here is the command :

    



    ffmpeg -loglevel verbose -re -i /home/SAFWAN/URI.mp4 -codec copy -sc_threshold 0 -b_strategy 0 -use_timeline 0 -use_template 1 -window_size 10 -init_seg_name init-$RepresentationID$.mp4 -strict -2 -f dash -segment_list_flags +live -min_seg_duration 2000000 -method PUT http://192.168.22.112/webdav/SAFWAN5/manifest.mpd

    



    But I am able to push hls segments using sample ffmpeg command :
ffmpeg -loglevel verbose -re -i /home/SAFWAN/URI.mp4 -codec copy -method PUT -f hls http://192.168.22.112/webdav/SAFWAN5/master.m3u8
