  • 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 (...)

  • Encoding videos locally or through a third party ?

    7 septembre 2015, par JordanDevelop

    We’re in the process on building a view uploading and sharing community right now and we’re currently developing with idea of using a third-party like Zencoder, but what makes Zencoder a better option ?

    I’m sorry if i butcher up what is involved with supporting a local encoding system, so I’ll try to be vague. We plan on releasing with AWS, so why not setup an instance running ffmpeg ? I understand it’s a lot more then simply that, but if is it that difficult to find someone who can put together an instance for encoding ?

    Am I right to assume most third party encoding services seem very unrealistic, price wise, for a web application who specifically focus on encoding large amounts of media ? I did notice Amazon offers an encoding features and would definitely feel more comfortable using them, but even that seems seems redundant.

    I completely understand the cost behind encoding is very real, but I just can’t understand why third-party encoders are so widely accepted.

  • FFmpeg CPU utilization

    9 août 2013, par user2565986

    I have a server running Scientific Linux. I'm trying to convert a large amount of videos and want to maximize cpu usage. My ffmpeg version is git-2013-08-06-a68b6ec.

    FFmpeg command :

    ffmpeg -y -i "$i" -c:v libx264 -preset fast -b:v "$VID_BIT" -threads 0 -c:a libfdk_aac -b:a "$AUD_BIT" -f mp4 /"$OUT_DIR"/"$MD5"

    I'm not sure why user usage is at 0% and the niced usage is all I see, but either way I'm looking for a way to get the usage up to 100%. Is there anyway to bolster the usage or is this the best I'm gonna get ?

  • 24 cores, 25 ffmpeg session - cpu looks good but load average high

    9 août 2012, par thevoipman

    I don't know if it's my script or just the system itself, but I definitely don't want to take anything down.

    I am running a centos 6.3 64bit with about 25 sessions of ffmpeg encoding

    1. I am trying to speed up ffmpeg encoding, but it seems like whatever ram or cpu I have, the encoding process still take very long. I have used -threads 0 or even -threads 16 to see if it speed up but it doesn't.

    2. My load average is very high, how can I lower this without terminating ffmpeg tasks ?
