• Small discord bot with a set of working music commands, about 6 days ago the play function completely stopped functioning (more below)

  24 février 2021, par TheColoradoKid

  It is a small discord python bot for my server with various features, which had included music commands until they stopped out of the blue without showing any error for the problem.
It uses FFMpeg, and youtubeDl along with pytube to gather the song and store it locally to play it, I have pip updated all of these and they are definitely on the current versions as I have made sure of this online.
Any help or insight anyone could provide would be greatly appreciated. I'm sorry if the code is convoluted in the way it's written I'm still pretty new to coding and this is one of my first proper larger projects.

  


  If you need any information I'm happy to give what I can to help.

  


  Here is the code for the play command :

  


  @client.command()
async def play(ctx, *args):
    global queu
    #global autom
    if not args:
        voice = get(client.voice_clients, guild=ctx.guild)
        if not voice.is_playing():
            server = ctx.message.guild
            voice_channel = server.voice_client
            if queu:
                async with ctx.typing():
                    player = await YTDLSource.from_url(queu[0], loop=client.loop)
                    voice_channel.play(player, after=lambda e: print('Player error: %s' % e) if e else None)

                await ctx.send('**Now playing:** {}'.format(player.title))
                del(queu[0])
                # while autom == True:
                #     try:
                #         a = client.get_command('auto')
                #         await ctx.invoke(a)
                #     except:
                #         print('')
            elif not queu:
                await ctx.send("You can't play if there isn't anything in the queue\nIf auto mode was on it has now been disabled, to use it gain please add to the queue and run ``;auto on``")
                autom = False
    if args:
        global gueu
        search_keywords = ""
        print(args)
        for word in args:
            search_keywords += word
            search_keywords += '+'
        link = "https://www.youtube.com/results?search_query="
        link += search_keywords
        #print(link)
        html = urllib.request.urlopen(link)
        video_ids = re.findall(r"watch\?v=(\S{11})", html.read().decode())
        url = ("https://www.youtube.com/watch?v=" + video_ids[0])
        #print(url)
        queu.append(url)
        #print(queu)
        await ctx.send("``{}`` added to queue!\n If the song doesn't start please either let the current song end and run ``;play``/``;next`` again or run ``;next`` to play now".format(url))
        try:
            p = client.get_command('play')
            await ctx.invoke(p)
        except:
            print('failed')


  


• Fluent-ffmpeg randomly doesn't add the text I want to the video, even though it's in the filters

  15 décembre 2022, par ToborWinner

  I am making a simple script to add some text to a 4 seconds video, it all works fine, but sometimes it randomly doesn't add some of the text.
You can find here the relevant parts of my code :

  


  
const video = ffmpeg('path/to/video.mp4')

let index = 0
let left = true

const filters = [{
  filter: 'drawtext',
  options: {
    //fontfile:'font.ttf',
    text: title,
    fontsize: 30,
    fontcolor: 'white',
    x: '(main_w/2-text_w/2)',
    y: 130,
    shadowcolor: 'black',
    shadowx: 2,
    shadowy: 2
  }
}]

for (let thought of thoughts) {
    if (thought.length == 0) {
      continue
    }
    thought = wrap(thought, {width: 35})
    const strings = thought.split("\n")
    let line = 0
    for (const string of strings
      .filter(string => string.length > 0)
      .map(string => string.trim())
      ) {
      let yoffset = 130+(130*(index+1))+(line*20)
      if (yoffset < 0) {
        yoffset = 0
      }
      console.log(string, yoffset)
      filters.push({
        filter: 'drawtext',
        options: {
          //fontfile:'font.ttf',
          text: string,
          fontsize: 18,
          fontcolor: 'white',
          x: `(main_w${left ? "*0.3" : "*0.7"}-text_w/2)`,
          y: yoffset,
          shadowcolor: 'black',
          shadowx: 2,
          shadowy: 2
        }
      })
      line++;
    }
    index++;
    left = !left
  }


video.videoFilters(filters)
video.noAudio()


video.save('path/to/output.mp4');



  


  The wrap function comes from the package word-wrap (const wrap = require('word-wrap');)
Thoughts is a list of strings that aren't too long (with the wrap function they end up being like 2-4 lines).

  


  This is inside an async function.

  


  For some reason only a few lines appear on the output video.
Sometimes, when it doesn't do that, it also throws an error saying that one of the inputs is invalid (while processing filters).
The wrap function seems to work, and also the yoffset, I have printed them.

  


  If someone has an idea why, please help me solve this.

  


  I tried chasing the text in thoughts, and for example, this works with no problems (shows the title, and the texts right, left, right, left, ...).

  


  const thoughts = ["Nothing is on fire, fire is on things","Nothing is on fire, fire is on things","Nothing is on fire, fire is on things","Nothing is on fire, fire is on things","Nothing is on fire, fire is on things"]


  


• Search pre-defined words in live stream video

  31 janvier 2018, par Brajraj Agrawal

  I want to search for some pre-defined keywords in youtube live stream ( or some other live stream) in my application.
  I have gone through the many articles. I just have a URL that is a live streaming URL and a set of keywords. If any of that keywords appear in the video I just want the user to provide a link to jump to that frame where the keyword appears in as real-time as possible.

  My understanding for that is to use Google Speech API and FFMPEG. But I am confused how can I do playback and which HTML player should I use for that.

  E.g. A video is streaming live and If a word "dog" is spoked in the video then the user should get notify with playback URL from 5 sec behind it appears in the video.

  Please suggest
