  • 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" (...)

  • Fix mismatched oc_mb_fill_cmapping11 signature.

    31 octobre 2014, par Tim Terriberry
    Fix mismatched oc_mb_fill_cmapping11 signature.
    

    oc_mb_fill_cmapping11() was defined without the last two parameters
    of its fellow mapping functions, meaning it got called with extra
    undeclared parameters.

    This could confuse the emscripten JavaScript cross-compiler's asm.js
    optimizations, as it's very picky about function signatures.

    Fixes #2068.
    Patch by Brion Vibber <brion@pobox.com>.

  • How to Crop the visible portion of landscape video in android ?

    30 août 2016, par Deepak
    1. I am working on Panning and cropping the landscape video using Texture View.I am in a half way that I can pan the landscape video from left to right vice versa by using this example
      https://github.com/crust87/Android-VideoCropView.

    enter image description here

    enter image description here

    1. FFMPEG can crop the particular portion of the video by using this command
      ffmpeg -i /sdcard/videokit/in.mp4 -filter:v crop=720:1088:0:0 -c:a
      copy /sdcard/videokit/out.mp4

    How can I crop only the video which is visible in Texture View and save it local storage in Android.

    crop=720:1088:0:0 is a hard coded width and height of the video and it is cropping fine.But how can I get the width and height of the visible video in Texture View to crop the visible video and Save it to the local storage in android.
