• How to close live streaming red5 server command in shell from php

  20 décembre 2016, par vibhor Gupta

  I have live streaming ffmpeg decode streaming streamed to client using red5 server to user browser.
  Now the problem is i have to run the ffmpeg command in ubantu server shell which keeps on streaming constantly to the user .
  So my problem is how to stop this live stream when user request .

  Environment :
  PHP version 5.5.9
  ffmpeg version 3.2.2
  Ubuntu 14.04.5 LTS
  

  The php script I use to execute the shell command is :
  

  $cmd = 'ffmpeg -i rtsp://user:12345@192.168.101.101/Streaming/Channels/101 -f flv -an rtmp://192.168.1.105/live/livestream/1.mp4' ;
  
          shell_exec($cmd);

  The above script never ends so i get the live streaming but if i place any other http request during the live streaming the server puts the request in queue and does not process any other request until the live streaming is closed .

  So how can i handle this condition is there any other function in php .

• ffmpeg how to start encoding at live point (not from beginning)

  9 avril 2021, par Jintor

  Is there a way with ffmpeg to start encoding at "live point" (in other words at last encoded frame...)

  


  let met explain : 2 ffmpeg process

  


  [1] x11grab that is being generated that started a 2:00 pm.... and still continue live (I don't want to stop and continue encoding live)

  


  [2] restream the [1] but at live point (at where it is encoding now) not from start...

  


  If [2] is being triggered at 2:15 pm, it will load the first frame of [1] (start to encode from 2pm)

  


  but I want that it load the last few frames of [1] as a starting point (2:15pm)...

  


  I know that I could ffmpeg -i -ss but I have to specify a x number of seconds after -ss...

  


  is there a better way ?

  


• Streaming jpegs live to iphone app

  14 février 2012, par Raven

  Im progressing through taking the depth camera feed from my kinect and streaming it to my iphone app. I have got to stage of being able save jpegs for every frame created from the kinect depth image (30 fps) and save them to the local disk. I have than been able to convert this to mpeg with ffmpeg.

  My question is now how can I view this live on my iphone ? Basically I want to view it live on the iphone as you are seeing it coming from the kinect.

  Should I use http live streaming and use the segmenter to use apples HttpLiveStreaming functionality ? Or can I stream the raw jpeg image files up in some way as they are saved to disk and than just cycle the images on the phone as they go ?

  Im wondering how video conferencing is achieved on the iphone (facetime/skype etc) ? because I'd prefer that it wasnt played inside the video player, just want to display live content on the screen as it happens.

  Any ideas ? Thanks in advance
