• FFMPEG move source video up inside overlay image frame box

  1er juin 2022, par Salem

  I'm trying to put video inside frame box like this one


  


  I tried to use overly filter, but the video edges, were covered by the frame , I want at least the lower edge of the video to be moved up (e.g 20px or y=-90) to match with the frame inside border, but I didn't know what code to used to change the source video coordinates .
this is my command

  


  ffmpeg -y -i source.mp4 -i 480_border.png -filter_complex "overlay=x=0:y=0" effict0.mp4


  


• stop or kill node media server

  9 juillet 2019, par user_66663333

  I am trying to implement stop feature for live video streaming using node-media-server.

  Basically I want to stop node-media-server completely, restart it later.

  const NodeMediaServer = require("node-media-server");
  
      let config = {
  
        logType: 3,
  
        rtmp: {

• Revision 8dd466edc8 : Changes to use of rectangular partitions. Changes to allow more use of rectangu

  24 juin 2015, par paulwilkins

  Changed Paths :
   Modify /vp9/encoder/vp9_encodeframe.c

  
   Modify /vp9/encoder/vp9_rdopt.c

  
   Modify /vp9/encoder/vp9_rdopt.h

  
   Modify /vp9/encoder/vp9_speed_features.c

  
  
  Changes to use of rectangular partitions.

  Changes to allow more use of rectangular partitions at
  speeds 1 and 2 for content classed by the first pass as
  animation and for blocks near the active image edge.

  This has quite a big impact in quality for the animated
  test sequence but also hurts encode speed for speed 2.

  For other content types the impact on both speed and
  quality is small.

  Added some plumbing for detection of internal vertical
  image edges.
