Emballe médias : à quoi cela sert ?
4 février 2011, parCe plugin vise à gérer des sites de mise en ligne de documents de tous types.
Il crée des "médias", à savoir : un "média" est un article au sens SPIP créé automatiquement lors du téléversement d’un document qu’il soit audio, vidéo, image ou textuel ; un seul document ne peut être lié à un article dit "média" ; -
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.

How to preserve data stream with none codec from a video while compressing it using ffmpeg ?
5 octobre 2022, par rj_7I'm using the following command to compress a video of size 1.5GB to 80 MB.


ffmpeg -i input.mp4 -copy_unknown -map_metadata 0 -c copy -c:v h264 -b:v 5000k -c:a aac -b:a 48k -map 0:v -map 0:a -map 0:d output.mp4



The problem I'm facing is - it doesn't copy the data stream to the output video even when I explicitly mention it via mapping. If I don't use the -map options for each kind of stream, it just process the video and audio as expected. But I also want the data stream in my output video.


The logs for the above command are -

I've also tried mapping the streams via number, that doesn't work either (shows same logs as above).


ffmpeg -i input.mp4 -copy_unknown -map_metadata 0 -c copy -c:v h264 -b:v 5000k -c:a aac -b:a 48k -map 0:0 -map 0:1 -map 0:2 output.mp4



So, essentially my question is - How to preserve data stream (packed) with none codec from a video while compressing it using ffmpeg ?

How do I use FFMPEG to live stream a video to Vimeo ?
9 janvier 2021, par KwixsterI'm attempting to live stream to Vimeo a pre-recorded video using a FFMPEG CmdLine. The following CmdLine works just fine if the video is 1280 x 720 but if the video is 1920 x 1080 it is jerky and unwatchable. I have the Vimeo account that allows live streaming. I know very little about FFMPEG ; the line I'm using is copied from another forum and modified (path to video file, URL, key) for my purposes. I know that my PC and internet speed (24 mbps upload) is more than capable of handling this. It works fine if a stream from Wirecast.


My ultimate goal is to write a program that streams videos to Vimeo and onto my website at a scheduled time without me having to be present to push a button. That part I've got handled. Its the FFMPEG part that I'm having trouble with.


Here's the CmdLine and the FFMPEG report :

FFmpeg filter_complex to merge audio from two files fails without an error due to album cover PNG stream

No errors are reported. But the output fails to run. The result log from FFmpeg looks something like this, which points to an PNG stream in one of the mp3.
