• The Mystery of the No such file or directory exception

  22 avril 2022, par JohnWick

  No idea what's going on here. Set a breakpoint after the for of loop in the following function. temp/concat.txt exists but the following exception is thrown :

  


  


  Uncaught Error Error : ffmpeg exited with code 1 : temp/concat.txt : No
such file or directory

  


  


  Outputting stderr gives a bit more info :

  


  


  [concat @ 000001e2e30124c0] Impossible to open
'temp/concat.txt#voiceover #funny #fall #lol.mp4' index.js:19
temp/concat.txt : No such file or directory

  


  


  And here is the contents of concat.txt, standard ffmpeg concat demuxer format :

  The function throwing the exception.

  


  async function makeCompilation(paths, outPath) {
  for (const filePath of paths) {
    await fs.appendFile(
      "temp/concat.txt",
      `file '${path.basename(filePath).replace("'", "\\'")}'${os.EOL}`
    );
  }
  return new Promise((resolve, reject) => {
    ffmpeg("temp/concat.txt")
      .inputOptions(["-f concat", "-safe 0"])
      .outputOption("-c copy")
      .on("stderr", (line) => console.log(line))
      .on("end", async () => {
        await fs.rm("temp/concat.txt");

• How do I make my discord bot play music by using youtubedl's search function instead of url ? (Python)

  28 septembre 2021, par PypypieYum

  I want it to search for the video and play it, how can i change the following code to achieve that ? Every time I use the ytsearch function in ytdl, I notice that it only searches for the first word of the title and download it, however, it causes error later on and do nothing.

  


  @commands.command()
    async def play(self, ctx, url):
        if ctx.author.voice is None:
            await ctx.send("You are not in a voice channel!")
        voice_channel = ctx.author.voice.channel
        if ctx.voice_client is None:
            await voice_channel.connect()
        else:
            await ctx.voice_client.move_to(voice_channel)

        ctx.voice_client.stop()
        FFMPEG_OPTIONS = {'before_options': '-reconnect 1 -reconnect_streamed 1 -reconnect_delay_max 5', 'options': '-vn'}
        YDL_OPTIONS = {'format':"bestaudio", 'default_search':"ytsearch"}
        vc = ctx.voice_client

        with youtube_dl.YoutubeDL(YDL_OPTIONS) as ydl:
            info = ydl.extract_info(url, download=False)
            if 'entries' in info:
              url2 = info["entries"][0]["formats"][0]
            elif 'formats' in info:
              url2 = info["formats"][0]['url']
            source = await discord.FFmpegOpusAudio.from_probe(url2, **FFMPEG_OPTIONS)
            vc.play(source)


  


  And this is the error message :

  


  Ignoring exception in command play:

    self.pid = _posixsubprocess.fork_exec(

The above exception was the direct cause of the following exception:

  Issue is that the program needs to be restarted every X minutes so that the list of media will update on it’s own. However, upon a restart, ffmpeg goes crazy and starts to spam a batch window under it’s name repeatedly over and over again without stopping. The only way out of it is to restart my computer.

  I’ve tried to use PM2, Forever, Supervisor. Nodemon afaik won’t auto restart.
