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.

FFmpeg 3.3.4 avfoundation to record only a specific section of the screen on macOS Sierra using the command line
16 octobre 2017, par antedeskI’m using FFmpeg version 3.3.4 (installed via brew) through the command line to record my desktop during some automated tests on my macOS Sierra (10.12.6).
I would like to record only a specific section of the screen but, unfortunately, I’m not able to find the proper options in the documentation to reach my goal.
According to the FFmpeg documentation for avfoundation, this is the command I use :
ffmpeg
-f avfoundation // avfoundation
-pix_fmt uyvy422 // pixel format
-i 1 // input: desktop
-r 30 // framerate for output
[PATH]/test.mp4 // filenameWhen I run this command I have the following output :

FFMPEG avi to streaming mp4
29 mai 2013, par VprnlI'm trying to get ffmpeg to encode various AVI files to mp4 for streaming purposes but my inexperience with the subject matter is making me doubt I'll ever get this to work.
I use this commandline :
ffmpeg -i test.avi -vcodec libx264 -r 24 -ac 2 -acodec ac3 -ab 128k -bt 240k -preset fast -strict -2 -b:v 320K -bufsize 62000 -maxrate 62000 -movflags frag_keyframe+empty_moov test.mp4
I use the " -movflags frag_keyframe+empty_moov" to make it possible to serve a fragmented mp4
And this is the log I get :

Thanks ![EDIT]
Sorry if I'm being unclear. I have two issues. First FFMPEG gives me an error (as you can see in the log) but I'm uncertain why I get this error and secondly, the stream does not actually work. The tanscoding starts, but the player never receives the video
