• librsvgdec : Fix frame clearing code

  1er février 2018, par Calvin Walton

  librsvgdec : Fix frame clearing code
  The existing code attempts to clear the frame by painting in OVER
  
  mode with transparent black - which is a no-op. As a result if you
  
  have many input frames (e.g. you're using a sequence of svg files),
  
  you'll start to see new frames drawn over old frames as memory gets
  
  re-used.
  Switch the code to paint using the CLEAR compositing operator,
  
  which fills every channel with 0 values (setting a source colour
  
  is not required).

• PHP and FFMPEG Remove Code in Video [on hold]

  6 janvier 2015, par user580950

  I have set of videos where i need to remove the code ( check below screen grab as an example ), you can see the code in RED .NOt sure if its possible to do it using PHP & ffmpeg or similar to detect a black box or hash key or serial no and blur out.

  It must be able to use mpeg-ts file input and output with mpeg-ts.

  Detection must be done and blurring must start 5 (configurable) seconds before the black box appears, this means we have to buffer the video and blur out the position where it will appear before it does.
