• Why does ffmpeg stop recording at midnight ?

  22 septembre 2019, par peter

  I have a shellscript like this under Kubuntu 19.10,

  #!/bin/bash
  
  
  
  while true
  
  do
  
      FILE=/media/petermc/Security5/Camera2/Camera2_.mp4  
  
      FILE=${FILE%.*}`date +%Y-%m-%d_%H-%M-%S-%N`.${FILE#*.}
  
      echo $FILE
  
  
  
      ffmpeg -rtsp_transport tcp -t 00:15:00 -i rtsp://*user*:*password*@192.168.1.60:554/ch02/0 -c copy -map 0 $FILE
  
  done

  It records files like this,

  Camera2_2019-09-21_23-36-57-874602376.mp4
  
  Camera2_2019-09-21_23-51-57-876639147.mp4

  Basically recording 15 minutes at a time from the RTSP feed, then starting a new file.

  However it stops working at midnight, the last few lines from the log file are this,

  frame= 3987 fps= 13 q=-1.0 size=  117760kB time=00:05:06.51 bitrate=3147.3kbits/s speed=1.01x    
  
  frame= 3994 fps= 13 q=-1.0 size=  118016kB time=00:05:07.07 bitrate=3148.4kbits/s speed=1.01x    
  
  frame= 4001 fps= 13 q=-1.0 size=  118016kB time=00:05:07.59 bitrate=3143.1kbits/s speed=1.01x    
  
  frame= 4008 fps= 13 q=-1.0 size=  118272kB time=00:05:08.11 bitrate=3144.6kbits/s speed=1.01x 

  So there doesn’t seem to be any error, it stops recording at 5 minutes into the last file with no error.

  Another piece of information is that I have 6 cameras, and 4 stopped recording, the ones connected to a DVR. I have a couple of IP cameras and they kept recording.

  What could be the cause of this ? Plus, what else could I do to work around this or diagnose this ?

  UPDATE :

  I believe the issue is because the DVR has a maintenance setup to restart once at week at midnight. If this is what happened, is there any way I can configure ffmpeg to restart if it has lost the stream ?

• prevent ffmpeg from opening console window

  10 février 2020, par Yesub

  I have a node/express server which is used to give streams from IP camera to a website. Everything is working well. I run that webserver with PM2 on a windows server.

  The problem : for each stream I have a windows console opening with just nothing logged in. The console reopen when I try to close it.

  Is there a way to prevent those console to open ?

  Here is the related node.js code :

  const { NodeMediaServer } = require('node-media-server');
  
  
  
  private _initiate_streams(): void{
  
      DatabaseProvider.instance.camerasDao.getCamerasList().pipe(
  
        take(1)
  
      ).subscribe(
  
          (databaseReadOperationResult: DatabaseReadOperationResult) => {
  
              if (databaseReadOperationResult.successful === true){
  
                const cameras = databaseReadOperationResult.result;
  
                const tasks = [];
  
                cameras.forEach( camera => {
  
                  tasks.push(
  
                    {
  
                      app : config.get('media_server.app_name'),
  
                      mode: 'static',
  
                      edge: camera.rtsp_url,
  
                      name: camera.stream_name,
  
                      rtsp_transport: 'tcp'
  
                    }
  
                  )
  
                });
  
  
  
                const configMediaServer = {
  
                  logType: 3, // 3 - Log everything (debug)
  
                  rtmp: {
  
                      port: 1935,
  
                      chunk_size: 60000,
  
                      gop_cache: true,
  
                      ping: 60,
  
                      ping_timeout: 30
  
                  },
  
                  http: {
  
                      port: config.get('media_server.port'),
  
                      allow_origin: '*'
  
                  },
  
                  auth: {
  
                      play: true,
  
                      api: true,
  
                      publish: true,
  
                      secret: config.get('salt'),
  
                      api_user: 'user',
  
                      api_pass: 'password',
  
                  },
  
                  relay: {
  
                      ffmpeg: 'C:\\FFmpeg\\bin\\ffmpeg.exe',
  
                      tasks: tasks
  
                  }
  
                };
  
  
  
                var nms = new NodeMediaServer(configMediaServer)
  
                nms.run();
  
              } else {
  
                  // catch exception
  
              }
  
          }
  
      );
  
    }

• Encode videos to send with WhatsApp

  28 avril 2017, par piegames

  I have a series of PNG images of a video I rendered and now I want so send it via WhatsApp. I used to encode my videos with the command from this answer, but apparently the videos can only be played from WhatsApp web ; on the phone I still get an error message. How do I convert them so that they can also be played on phone ?

  Command used :

  %PATH_TO_FFMPEG%\ffmpeg.exe -i paint\out%04d.png -c:v libx264 -c:a aac ./videos/out7.mp4
