  • Installation en mode ferme

    4 février 2011, par

    Le mode ferme permet d’héberger plusieurs sites de type MediaSPIP en n’installant qu’une seule fois son noyau fonctionnel.
    C’est la méthode que nous utilisons sur cette même plateforme.
    L’utilisation en mode ferme nécessite de connaïtre un peu le mécanisme de SPIP contrairement à la version standalone qui ne nécessite pas réellement de connaissances spécifique puisque l’espace privé habituel de SPIP n’est plus utilisé.
    Dans un premier temps, vous devez avoir installé les mêmes fichiers que l’installation (...)

  • How to modify x264 source code to get motion search time [on hold]

    21 octobre 2017, par Yicheng Li

    I am a new member of stack overflow, I hope you guys can help me solve this problem.
    I am now using x264 with ffmpeg to encode some raw video, I was asked how much time the motion search would cost in libx264 video coding. Therefore, I need to modify the code, I tried put the clock around the switch sentence in the encoder/me.c
    clock start

    clock end
    After compiling the source code and run a test,
    it shows that the time is very small and it seems I am actually getting the time each macro block spent on motion search.

    So, how should I modify the x264 source code to get the time duration in motion search.

    Big Thanks.

  • ffmpeg - How do I capture AND rotate a video at the same time ?

    21 août 2019, par A R

    I need to record video from a USB camera using ffmpeg. The issue is that the camera is upside down and can’t be repositioned, so I have to rotate 180°.

    So far I’m using this command to capture :

    ffmpeg -framerate 30 -video_size 1280x720 -t 00:58:00 -i /dev/video0 output.mp4

    And then I rotate it using this other command :

    ffmpeg -i output.mp4 -vf "rotate=180*(PI/180), format=yuv420p" -metadata:s:v rotat=0 -codec:v libx264 -codec:a copy ROTATED_output.mp4;

    Both commands are working perfeclty but it takes me twice the time. Is it possible to capture with the filter enabled so that the frames are rotated before being saved the first time ?

  • trying to create thumbnail per 10 second and scaling them at same time

    25 juin 2014, par user3774884

    i need to convert one video file every 10 second into one image or thumbnail. and at the same time i want to convert image width to 320 pixels and height according to width so that aspect ratio can be maintained.I am using the code written below

    "ffmpeg -i "inputfile" -f image2 -vf fps=fps=1/10,thumbnail,scale=360:trunc(ow/a/2)*2 putputfile%08d.jpg"

    its showing one syntax error near unexpected token ’(’"
