  • 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.

  • Mix additional audio file with video(+audio) in ffmpeg

    21 mai 2019, par Serg

    I’m trying to mix additional audio file with video which has also audio within. But the problem is that I already have complex ffmpeg command and don’t know how to combine them together.

    This is my existing ffmpeg command which uses some offsets and replaces additional audio file with embedded one (audio inside video) and also overlays few gauges and watermark to the video.

    ffmpeg -y
    -ss 00:00:01:213 -i videoFile.mp4
    -ss 00:00:03:435 -i audioFile.wav
    -i watermark.png
    -framerate 6 -i gauge1_path/img-%04d.png
    -framerate 1 -i gauge2_path/img-%04d.png
    -framerate 2 -i gauge3_path/img-%04d.png
    -framerate 2 -i gauge4_path/img-%04d.png
    -framerate 2 -i gauge5_path/img-%04d.png
    -framerate 2 -i gauge6_path/img-%04d.png
    -filter_complex [0][2]overlay=(21):(H-h-21)[ovr0];
    [ovr0][3]overlay=(W-w-21):(H-h-21)[ovr1];
    [ovr1][4]overlay=(W-w-21):(H-h-333)[ovr2];
    [ovr2][5]overlay=(W-w-21):(H-h-418)[ovr3];
    [ovr3][6]overlay=(W-w-21):(H-h-503)[ovr4];
    [ovr4][7]overlay=(W-w-21):(H-h-588)[ovr5];
    [ovr5][8]overlay=(W-w-21):(H-h-673)
    -map 0:v -map 1:a -c:v libx264 -preset ultrafast -crf 23 -t 00:5:10:000 output.mp4

    Now I would like to use ffmpeg's amix in order to mix both audios instead of replacing them, if possible with ability to set volumes. But official documentation amix says nothing about volume.

    Separately both seems to work ok.

    ffmpeg -y -i video.mp4 -i audio.mp3 -filter_complex [0][1]amix=inputs=2[a] -map 0:v -map [a] -c:v copy output.mp4

    and

    ffmpeg -y -i video.mp4 -i audio.mp3 -i watermark.png -filter_complex [0][2]overlay=(21):(H-h-21)[ovr0] -map [ovr0]:v -map 1:a -c:v libx264 -preset ultrafast -crf 23 output.mp4

    but together

    ffmpeg -y -i video.mp4 -i audio.mp3 -i watermark.png -filter_complex [0][1]amix=inputs=2[a];[a][2]overlay=(21):(H-h-21)[ovr0] -map [ovr0]:v -map [a] -c:v libx264 -preset ultrafast -crf 23 output.mp4

    I’m getting an error :

  • FFMPEG Steam Stream stop after a few min

    24 novembre 2022, par Fabian Boulegue

    I try set a video stream to STREAM via FFMPEG so far everything works fine but after a few min it just seem to timeout (at last the stream stops but ffmpeg still send everything)

    



    Here is the ffmpeg string

    



    OUTRES="1920x1080"
GOP="60"
GOPMIN="15"
THREADS="4"
CBR="2500k"

    /Users/livvy/Desktop/help.MOV: Invalid data found when processing input
    Livvys-MacBook-Air:~ livvy$

    I have tried to install ubuntu, - to try and generate a new moov atom for the file by using a working video taken on the same device - it tells me I need to install a JVD, tried that and can’t export the file.
    Basically, I do not code and trying to do this off of various google searches.
    Is there an easier way to install a moov atom to this video without accidently effing up my computer with faulty code ? Or should I just give up and lose the videos ?

    Any help appreciated - sorry for lack of knowledge/hopelessness
