  • 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 to get AVPacket from OSX CMSampleBufferRef

    30 mars 2015, par wao813

    I’m new in AV technology and have been trying to combine FFmpeg with Apple’s CoreVideo framework to process webcam captures.

    First, i have webcam captures from CoreVideo(which could be found from AVCaptureVideoDataOutputSampleBufferDelegate) represented by CMSampleBuffer

    - (void)captureOutput:(AVCaptureOutput *)captureOutput
    
  didOutputSampleBuffer:(CMSampleBufferRef)sampleBuffer 
    
  fromConnection:(AVCaptureConnection *)connection {}

    From that, without store as temporary file, I would like to make it to FFmpeg’s AVPacket so I can process.

    Does anyone know which FFmpeg api I should be looking into ?

  • Conditionally rotate portrait video if landscape with FFmeg

    12 novembre 2019, par Jules

    I need to convert only portrait videos to landscape, some video maybe landscape already.

    I need to achieve this with a shell script on a mac.

    I’ve previously managed to rotate a video with ..

    ffmpeg -i "/Users/jm/Library/Mobile Documents/com~apple~QuickTimePlayerX/Documents/output.mp4" 
    
-strict 1 -metadata:s:v rotate="90" -codec copy "$3"

    $3 is the input file in my shell script

    I’ve found this ...

    ffmpeg -i input.m4v 2>&1 | grep rotate

    From this answer https://stackoverflow.com/a/31683689/450456

    I’m not sure how to combine the two, or have to get and use the height and width in an if statement in a shell script.
