  • 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" (...)

  • How can I create a side-by-side live video stream output from two separate live webcam feed using ffmpeg ? [duplicate]

    10 août 2021, par shudfht85

    I would like to combine two live webcam feeds of same resolution (say 1280 X 1024) into one side-by-side live video feed output (2560X1024) using ffmpeg.
I found some code from here : https://ffmpeg.org/ffmpeg-filters.html#overlay

    


    ffmpeg -i left.avi -i right.avi -filter_complex "
nullsrc=size=200x100 [background];
[0:v] setpts=PTS-STARTPTS, scale=100x100 [left];
[1:v] setpts=PTS-STARTPTS, scale=100x100 [right];
[background][left]       overlay=shortest=1       [background+left];
[background+left][right] overlay=shortest=1:x=100 [left+right]
"


    


    However, I do not know how I can change the input video from MP4 to a live webcam feed. Any help would be appreciated. Thanks.

    


  • How to avoid stopping or record all dynamic videos in the process of capturing screen video with ffmpeg from a python program ?

    3 décembre 2020, par fengnix

    I have many robotframework test cases and in the first case, a ffmpeg command like the following is invoked to record the whole running process :

    


    ffmpeg -framerate 30 -f gdigrab -i desktop -c:v libx264rgb -crf 0 -preset ultrafast output.mkv


    


    Whenever I firstly run all cases and then manuually run the above command from an addition command console, the recorded video always looks fine, it looks like all contents on the screen can be correctly captured.

    


    However, once I execute the command the same as the above one in the first case by call the following code :

    


    p=subprocess.Popen(cmd, shell=True, stdin=subprocess.PIPE, stdout=subprocess.PIPE, stderr=subprocess.PIPE)


    


    and then in the final test case the record process is stopped by calling the following code to tell ffmpeg that we want to stop the recording :

    


    p.stdin.write(bytes("q",'UTF-8'))  


    


    the final result video only contain correct contents of the "start" and the "end" of the whole process, but all other contents no longer changed and seemd just a static image, which means all the dynamic effects on the screen cannot be captured.

    


    Could anyone be so kind as to let me know what the matter is and how to solve it ?
