  • Déploiements possibles

    31 janvier 2010, par

    Deux 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 amerge Error while filtering : Cannot allocate memory

    21 mars 2019, par Recessive

    This seems to be a recurring problem, as seen here : ffmpeg Error while filtering : Cannot allocate memory . I ask this only because that question has no answer.

    I get a memory error every time I try to use amerge to combine music and a video (with audio). I am at a loss as to how to get around this, so if there are any other command line alternatives that do the same thing (combining audio with video, merging the new audio and the current audio on the video) any suggestions would be much appreciated.

    FYI, here is the ffprobe information for the two files I am trying to combine :

  • Where can I find my output video file after execution of ffmpeg command

    7 août 2019, par Giri Aakula

    I run this command to capture my screen

    ffmpeg -video_size 1366x768 -framerate 60 -f gdigrab -i desktop -c:v libx264 -crf 0 -preset ultrafast output.mp4

    I didn’t find the output.mp4 file anywhere in my HDD. I checked in the bin folder of ffmpeg it is not there.
    I searched the whole PC I didn’t find it anywhere. Can anyone please help me out to find the file.
    The console output is

    C:\Users\USER>ffmpeg -video_size 1366x768 -framerate 60 -f gdigrab -i desktop -c:v libx264 -crf 0 -preset ultrafast output.mp4
