  • Creating farms of unique websites

    13 avril 2011, par

    MediaSPIP platforms can be installed as a farm, with a single "core" hosted on a dedicated server and used by multiple websites.
    This allows (among other things) : implementation costs to be shared between several different projects / individuals rapid deployment of multiple unique sites creation of groups of like-minded sites, making it possible to browse media in a more controlled and selective environment than the major "open" (...)

  • 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 ?

  • 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.
