  • 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" (...)

  • Python - How to trim black boarder from video (top, bottom, sides)

    18 décembre 2022, par perry_the_python

    If I have a .mp4 video file with black boarders on the top, bottom, and/or sides, How can I trim these boarders off with python ?

    


    I do not want to replace the boarders with anything, I just want to trim the video.

    


    For example, if I run magically_trim_black_boarders_from_vid(in_vid) on a video that looks like the frame below, the video's height would not change, but its width would be reduced.

    


    enter image description here

    


    Thanks !

    


  • Using GDIgrab in FFmpeg with dshow Audio produces black screen

    16 mars 2016, par Spreadys

    here is my command :

    ffmpeg -f gdigrab -framerate 25 -offset_x 10 -offset_y 10 -show_region 1 -draw_mouse 1 -video_size 1280x720 -i desktop -f dshow -i audio="Microphone (2- ATR USB microphone)" -r 25 -threads 4 -c:v libx264 -pix_fmt yuv422p -preset superfast -tune fastdecode -x264opts keyint=25:min-keyint=1 -crf 4 -c:a aac -profile:a aac_low -async 25 "C:\Users\david\Desktop\%output%.mp4"

    The gdigrab video works great when it is on its own (no audio). The audio works fine when it is on its own (no video). When I join the two commands to capture both together, as soon as I move a window within my capture area, the area goes black.

    In Windows 7, I used to get around this by stopping the desktop composition service prior to capture, (SC stop uxsms), but this is now not possible in Win10.

    I thought it may be something graphics card related.
    My main monitor is on an Nvidia card, with my second running from the onboard Intel. This is setup for Quicksync H264 playback and encoding with my NLE.

    I know that I could use a dshow screen capture driver such as UScreen but am trying to avoid that as I need the capture area to be specified each time from a simple batch.

    Any help appreciated to solve this black area problem- its driving me crazy !

  • ffmpeg how to end video with a black frame/solid color

    10 mai 2021, par request

    I'm scaling 2 videos of different sizes and hstack them side by side together.

    


    If the length of the two videos is different and for example the first one is over, then it shows the last frame of that video the whole time. I want it to show nothing / a black frame until the other video is over

    


    My code so far :

    


    ffmpeg -i vid1.mp4 -i vid2.mp4 -filter_complex "[1][0]scale2ref[2nd][ref];[ref][2nd]hstack" -vsync 0 output.mp4


    


    How could this be achieved ? (something with tpad or stop_mode maybe ?)

    


    Here are two sample videos to test with :

    


    testvid1
