• I want to get subtitles of images with CLI

  30 avril 2018, par user3387068

  I have movie data that BD has riped, with subtitles inside.
  Just that subtitle is saved as an image.
  So I’d like to get that subtitle image with CLI.
  Is there a good tool ?

  I will also post movie information from ffmpeg.

  Stream #0:0: Audio: flac, 48000 Hz, stereo, s32 (24 bit) (default)
  
  Stream #0:1: Subtitle: hdmv_pgs_subtitle (default)
  
  Stream #0:2: Subtitle: hdmv_pgs_subtitle

• issue with ffmpeg (not loading song ?) - ffmpeg stream : write EPIPE

  15 novembre 2020, par super

  issue : with some songs that i play through the StreamDispatcher from the discord.js module (seems to be ones that have silences at the beginning), the dispatcher will almost immediately finish and throw an error. i use the ffmpeg-static module.

  


  from what i've seen, these are the two errors that i'm receiving from calling the "debug" and "error" events of the dispatcher

  


  Error: ffmpeg stream: write EPIPE

  


  Error [ERR_STREAM_DESTROYED]: ffmpeg stream: Cannot call write after a stream was destroyed

  


  reproducible code sample (requires ytdl-core) :

  


  /**
* @param {Discord.VoiceConnection} connection 
* @param {String} url 
*/
async function run(connection, url) // assuming these two variables aren't null
{
    const video = ytdl(url, { highWaterMark: 5242880 });
    video.on("error", (err) => console.log(err));
    let dispatcher = connection.play(video);
    dispatcher.on("finish", () => console.log("finished"));
    break;
}
// recommended url: https://www.youtube.com/watch?v=Auk1oVI2Icw
// (this is one i've been using to test this issue)


  


  original code from my project plus some comments from guiding :

  


  async play() // this is my function for playing music on the bot
{
    if (this.queue.length === 0) return;
    if (!this.guild.me.voice || !this.guild.me.voice.channel) return;
    let connection = this.guild.me.voice.connection;
    if (!connection) return;
    if (connection.dispatcher) return;
    let track = this.queue[0];
    let channel = this.guild.channels.cache.get(track.channelID);
    switch (track.type)
    {
        //case "soundcloud" omitted
        case "youtube":
        {
            const video = ytdl(track.url, { highWaterMark: 5242880 });
            video.on("error", (err) => console.log(err));
            channel.send(`playing: **${track.name}** // requester: **${track.requester.tag}**`);
            let dispatcher = connection.play(video); // dispatcher will begin
            dispatcher.setVolume(this.volume);
            dispatcher.on("finish", () => this.finish()); // almost immediately the following will be called
            // fyi: there isn't anything special in the function called, just some code to shift the queue
            break;
        }
    }
}
