Déploiements possibles
31 janvier 2010, parDeux types de déploiements sont envisageable dépendant de deux aspects : La méthode d’installation envisagée (en standalone ou en ferme) ; Le nombre d’encodages journaliers et la fréquentation envisagés ;
L’encodage de vidéos est un processus lourd consommant énormément de ressources système (CPU et RAM), il est nécessaire de prendre tout cela en considération. Ce système n’est donc possible que sur un ou plusieurs serveurs dédiés.

syncing a video file with audio using ffmpeg is returning a video without audio
31 juillet 2019, par abboodWhen I attempt to sync a .mov video with an .m4a audio file using ffmpeg like so
ffmpeg -ss 00:00:2 -i test.m4a -i test.mov -c:v copy -c:a aac -strict experimental output.mp4
it works like a charm. But right now I’ve recorded a usability test video using adobe XD, and it returned an .mp4 (MPEG-4) video and I manually recorded the audio using quicktimre returning a .m4a audio file.
Trying to merge them using ffmpeg is returning a video without any audio :
ffmpeg -i video.mp4 -i audio.m4a -c:v copy -c:a aac -strict experimental output.mp4

Anomalie #4369 (En cours) : YQL n’est plus actif
7 août 2019, par Ybbet SPIPBonjour tout le monde,
J’ai envoyé un message sur la liste SPIP-Dev. Je crée un ticket pour traçabilité.
SPIP offre depuis la boucle DATA la source YQL. Cf. code ici : https://core.spip.net/projects/spip/repository/entry/spip/ecrire/iterateur/data.php#L642
Malheureusement, le service est fermé depuis le 3 janvier 2019. cf. https://news.ycombinator.com/item?id=18785255Je n’ai pas trouvé de solutions alternatives équivalentes en ligne. Que du Desktop "freemium" quand une solution existe.
Il existe https://vespa.ai/ qui est à installer sur une machine.
Autre élément trouvé https://www.pipes.digital/
Je ne suis pas sûr qu’on retrouve une souplesse telle que l’était YQL.Bien à vous,

FFMPEG Incredibly Slow On Windows Server 2016
1er août 2019, par Ben GardnerI have a t2.small (2GB RAM, 1 vCPU) Amazon EC2 instance running a process using FFMPEG. It runs just fine ( 30 fps) on my computer (i7, 12GB RAM), but at around 2 fps on the server. Here’s the command :
rescale_command = f'ffmpeg -i {srcVideo} -filter_complex \"scale={owidth}:{oheight}, setsar=1:1, pad={dim[0]}:{dim[1]}:{oofx}:{oofy}\" {destVideo}'
I’ve tried uninstalling and reinstalling ffmpeg/ffprobe
Edited per llogan’s request, I’ve also discovered that it’s relatively speedy towards the beginning (I’m rescaling 100 times over the course of the program) and slows down towards the end.
It utilizes 100% of the CPU even from the beginning, though.
Example command/output :
ffmpeg -i media/8-1-2019/hi/dl-107.mp4 -filter_complex "scale=607:1080, setsar=1:1, pad=1920:1080:656:0" media/8-1-2019/hi/sl-107.mp4
