• DiscordJS Music Bot Connects and Then Immediately Disconnects From Voice Channel

  23 janvier 2020, par კΙбthebraɨɴs

  I see that questions similar to this one have been asked, and after following their solutions I still end up the same as I started. Below I have listed my code, a link to test it with a sample bot I created, and the modules you will need to test it using a self-hosted instance.

  My problem is that upon connecting to the specified voice channel, the bot immediately leaves afterwards without any signs of errors or exceptions. I’m not sure if it is a problem with my code, or with one of the libraries I am using. The only console output I receive is as follows :

  Bot Ready For Use
  
  joined channel
  
  left channel

  Thanks !

  My Code

  var voiceChannel = message.member.voiceChannel;
  
  
  
  if (!message.member.voiceChannel) return message.channel.send(`You do realize you have to be in a voice channel to do that, right ${message.author.username}?`)
  
  
  
  if (!message.member.voiceConnection) voiceChannel.join().then(async connection => {
  
  
  
      let streamURL = args.slice(1).join(" ")
  
      let streamTitle = "";
  
      let streamThumb = "";
  
      let streamAuth = "";
  
      let streamAuthThumb = "";
  
  
  
      if (streamURL.includes("https://www.youtube.com") || streamURL.includes("https://youtu.be/") && !streamURL.includes(' ')) {
  
          let results = await youtube.getVideo(streamURL)
  
  
  
          let {
  
              body
  
          } = await snekfetch.get(`https://www.googleapis.com/youtube/v3/channels?part=snippet&id=${results.channel.id}&fields=items%2Fsnippet%2Fthumbnails&key=${ytapikey}`).query({
  
              limit: 800
  
          })
  
  
  
          streamTitle = results.title
  
          streamThumb = results.thumbnails.medium.url
  
          streamAuth = results.channel.title

• ffmpeg.js running extremely slow in iOS cordova (but fine in iOS safari ?)

  14 mai 2019, par PEWify

  I’m trying to create a phonegap app that converts videos into maybe 30 or so jpeg frames..
  This page converts a bigbuckbunny video into 30 frames > https://www.pewify.com/test/ (taken from https://bgrins.github.io/videoconverter.js/demo/)

  It runs fine on an iPhone x running iOS 12 in mobile safari, it takes about 12-15 seconds to complete, but the same code packaged into a iOS cordova app running on the same phone will take almost 160 seconds to complete (both end results the same, but almost 10x as long), it works fine for android browsers or an android cordova app though

  I’m using cordova android 7.0 and cordova ios 4.5.4 (phonegap cli-8.0.0) for the app

  I’ve tried removing all unneeded plugins with just the bare minimum code but to no effect, it still runs just as slow

  From what i understand phonegap is just using a webview similar to safari to render the app but in this case it works but much slower, on top of that the phone starts to get heated up (presumably doing some intensive CPU ?)

  Did read something about using WKWebview being faster in cordova instead but that messes up the app with lots of CORS and ’operation insecure" errors so have decided not to implement that for now (unless that is the solution ?)

  Hopefully someone can point me in the right direction as i’m not exactly sure what is the issue here as it works somewhat flawlessly in android (both chrome and phonegap) but only in iOS safari and not the phonegap app

• How to open a HEIF (.heic) image ?

  14 décembre 2022, par Jean-Milost Reymond

  For a c++ project, I need to open and show a HEIF (.heic) image. What I know (if I'm right) is that the HEIF images are based on the ffmpeg standard, and requires a H265 codec to be read.

  



  I found several open-source H265 codecs :

  



  

  • OpenHEVC (https://github.com/OpenHEVC/openHEVC)

  


  • x265 (https://bitbucket.org/multicoreware/x265/downloads/)

  


  • libde265 (https://github.com/strukturag/libde265)

  


  



  I can open and show H265 encoded video files with each of them, but I'm unable to simply open, show or convert a .heic image. All of them return an error, or just do nothing.

  



  To be honest I'm a little puzzled, because the HEIF standard seem to be a well kept secret. I'm unable to find a relevant info that could allow me to walk to a solution. Those I found are just tricks and workarounds, like e.g. forcing the device (I'm speaking here about the Apple iPhone using the new iOS11) to generate a jpg image instead of a heic, or using a third party application like dr.fone. Of course these solutions are irrelevant for me.

  



  So, somebody can tell me which codec I should use with a .heif image, and how I can use it to open it ? Or are there open source libraries or examples that allow to manipulate this type of image file ? Somebody can point me to the good direction ?
