• how to locate the voice chat that the discord bot is connected to

  10 mars 2019, par SwaggZ ReYan

  I am making a discord bot that is being activated by voice recognition, im at the very beginning right now im making him join a voice channel (which is working), and im trying to make a command to make him leave.

  const commando = require('discord.js-commando');
  
  
  
  class LeaveChannelCommand extends commando.Command
  
  {
  
      constructor(client){!
  
          super(client,{
  
              name: 'leave',
  
              group: 'music',
  
              memberName: 'leave',
  
              description: 'leaves a voice channel'
  
          });
  
      }
  
      async run(message, args)
  
      {
  
          if(message.guild.voiceConnection)
  
          {
  
              message.guild.voiceConnection.disconnect();
  
          }
  
          else
  
          {
  
              message.channel.sendMessage("seccessfully left")
  
          }
  
      }
  
  }
  
  
  
  module.exports = LeaveChannelCommand;

  right now you can type !leave from anywhere in the server and the bot leaves,
  i want to make it possible to control him only from the same voice channel,
  what should i do

• RTSP Feed Screen Cutoff

  25 août 2021, par Jackson Medina

  Recently I have been trying to consume the RTSP stream from a Vivitar Folding Drone. By reverse-engineering the .apk file for the Vivitar Folding Drone app, I was able to find that the RTSP address for the drone is rtsp://192.168.1.1:7070/webcam however, whenever I consume this stream through VLC or FFPLAY, most of the feed gets cut off and replaced with a green screen or gray screen (depends on whether I save to a .mjpeg file or a .dump file). What is the cause of this problem and what steps can I take to fix it ?

  


  

  


  When using FFPLAY, I use the following command :

  


  ffplay -i -rtsp_flags rtsp://192.168.1.1:7070/webcam


  


  I also receive this error when I first start consuming the stream with ffplay :

  


  [swscaler @ 00000240daeadf80] deprecated pixel format used, make sure you did set range correctly


  


  I receive this error message for about every frame of the stream :

  


  [mjpeg @ 00000240d6226b00] mjpeg_decode_dc: bad vlc: 0:0 (00000240d6266050)
[mjpeg @ 00000240d6226b00] error dc
[mjpeg @ 00000240d6226b00] error y=1 x=0


  


  NOTE : I am unsure if this is relevant, but the Vivitar Drone creates its own wifi network that must be signed onto if you want to consume the RTSP stream

  


  Also, the drone feed works perfectly fine when viewed through the Vivitar Folding Drone app. I just can't seem to get it to display properly through FFPLAY, FFMPEG, or VLC.

  


  UPDATE :

  


  Upon further inspection, it seems like the Vivitar Folding Drone may not be sending all of the jpg data for a single frame. Here is an image generated by unaltered byte data sent through the RTSP feed.


  


  I noticed three things from this image :

  


  

  1. The image appears to be missing large chunks of data.

  


  2. The image appears to be redshifted

  


  3. The two visible portions of the image should be sequential (it looks as though the second visual portion lines up with the first). An example of this can be seen below.

  


  


• How can I transform a sequence of images into a playable video using LibVLCSharp ?

  9 février 2021, par adamasan

  I have a sequence of images that I was able to extract from a video using LibVLCSharp. This sample to be more specific. I'm creating a small video library manager for learning purposes, and I would like to extract frames and create thumbnails to play when the user hovers the mouse over the previewer.

  


  Using the aforementioned sample I was able to create a WPF UI around the same loging and extract the frames from a video file. However what I want now is to convert these extracted frames into a video file, using them as preview for the video, just like happens on YouTube.

  


  I wasn't able, however, to find out how to achieve this using LibVLCSharp or just LibVLC. Using this answer on Super User I was able to achieve my goal and put those frames together into a video using ffmpeg.

  


  I haven't taken the time yet to study FFmpeg.Autogen, so I don't know if I would be able to extract the frames from the video files in the same way I can do with LibVLCSharp, but I don't see with good eyes using both libraries on my application, one to export the frames and one to generate these frames into a video.

  


  So, is there a way to get the output frames and convert them into a playable video using LibVLCSharp (or libvlc) itself ?
