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

  20 December 2016, by 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 .

      $library_data = [
  
          'library_title' => request()->input('title'),
  
          'library_short_text' => request('short_text'),
  
          'library_body' => request('body'),

      $new_library_object = Library::create($library_data);
  
      if (count($request->file('fileItem')) > 0 && is_array($request->file('fileItem')) ){
  
          foreach ($request->file('fileItem') as $file){

                  $file_data['file_name'] = $new_file_name;
  
                  $file_data['file_title'] = $new_file_name;
  
  
  
                  $new_file_object=$new_library_object->files()->create($file_data);
  
  
  
              }
  
          }
  
      }elseif (count($request->file('fileItem')) > 0 && !is_array($request->file('fileItem'))){
  
  
  
          $file_data=[
  
              'file_type'=> $request->file('fileItem')->getMimeType(),
  
              'file_size'=> $request->file('fileItem')->getClientSize(),
  
          ];
  
  
  
  
  
          $new_file_name = str_random(45).'.'.$request->file('fileItem')->getClientOriginalExtension();
  
          $result = $request->file('fileItem')->move(public_path('files'),$new_file_name);

              $file_data['file_name'] = $new_file_name;
  
              $file_data['file_title'] = $new_file_name;
  
  
  
              $new_file_object=$new_library_object->files()->create($file_data);
  
  
  
          }
  
      }

  then I dont know how use this codes to Create a frame from a video

  FFMpeg::fromDisk('videos')
  
  ->open('steve_howe.mp4')
  
  ->getFrameFromSeconds(10)
  
  ->export()
  
  ->toDisk('thumnails')
  
  ->save('FrameAt10sec.png');

  whate is ’videos’ in fromdisk and in my codes how use this parametrs

  I use this code `

  $new_file_object=$new_library_object->files()->create($file_data);
  
              $start = \FFMpeg\Coordinate\TimeCode::fromSeconds(5);
  
              $clipFilter = new \FFMpeg\Filters\Video\ClipFilter($start);
  
              FFMpeg::fromDisk('files')
  
                  ->open($new_file_object->file_name)
  
                  ->addFilter($clipFilter)
  
                  ->export()
  
                  ->toDisk('files')
  
                  ->inFormat(new \FFMpeg\Format\Video\X264)
  
                  ->save('short_steve.mkv');

  but I have this erroe

  Non-static method Pbmedia\LaravelFFMpeg\FFMpeg::fromDisk() should not be called statically

• ffmepg Low latency destkop mirroring with quicksync

  21 February 2016, by Alan Aasmaa

  I have tried to figure out long time how can i stream my Main PC to Secondary PC.

  I’d like to use QuickSync or NVENC
  https://github.com/illuspas/ffmpeg-hw-win32 ?

  I found something like this.
  ffmpeg \
  -f x11grab -s 1280x720 -framerate 60 -i :0.0 \
  -c:v mpeg2video -q:v 20 -pix_fmt yuv420p -g 1 -threads 2 \
  -f mpegts - | nc -l -p 9000

  I know x11grab is for linux so i should use dshow ?

  What would be best client to watch this ? I need also low CPU usage.

  Right now i got best latency 0.5sec by Streaming with action and reciving with vMix (I use vMix becose i stream back into OBS).

  My purpose is to Get CSGO from one PC to another and do a PiP stream. I don’t have capturecard and i dont have streaming PC. Also i don’t have money to buy neither of these.
