• Discord 24/7 video stream self-bot crashes after a couple hours

  21 juillet 2023, par angelo

  I've implemented this library to make a self-bot that streams videos from a local folder in a loop 24/7 (don't ask me why). I set up an ubuntu vps to run the bot and it works perfectly fine the first 2-3 hours, after that it gets more and more laggy until the server crashes.
pd : It's basically my first time using javascript and stole most of the code from this repo so don't bully me.

  


  Here's the code :

  


  import { Client, TextChannel, CustomStatus, ActivityOptions } from "discord.js-selfbot-v13";
import { command, streamLivestreamVideo, VoiceUdp, setStreamOpts, streamOpts } from "@dank074/discord-video-stream";
import config from "./config.json";
import fs from 'fs';
import path from 'path';

const client = new Client();

client.patchVoiceEvents(); //this is necessary to register event handlers

setStreamOpts(
    config.streamOpts.width,
    config.streamOpts.height,
    config.streamOpts.fps,
    config.streamOpts.bitrateKbps,
    config.streamOpts.hardware_acc
)

const prefix = '$';

const moviesFolder = config.movieFolder || './movies';

const movieFiles = fs.readdirSync(moviesFolder);
let movies = movieFiles.map(file => {
    const fileName = path.parse(file).name;
    // replace space with _
    return { name: fileName.replace(/ /g, ''), path: path.join(moviesFolder, file) };
});
let originalMovList = [...movies];
let movList = movies;
let shouldStop = false;

// print out all movies
console.log(`Available movies:\n${movies.map(m => m.name).join('\n')}`);

const status_idle = () =>  {
    return new CustomStatus()
        .setState('摸鱼进行中')
        .setEmoji('🐟')
}

const status_watch = (name) => {
    return new CustomStatus()
        .setState(`Playing ${name}...`)
        .setEmoji('📽')
}

// ready event
client.on("ready", () => {

  I've tried running the code with the nocache package, setting up a cron job to clean the cache every 5 minutes, unifying functions in the code, but nothigns works.
I think that the problem has to do with certain process that never really ends after one video finishes playing, probably ffmpeg. I don't know whether is my code, my vps or the library the problem.

  


  I wanted the bot to stay in the voice channel streaming my videos 24/7 (no interruptions), I don't know how to prevent it from getting laggy after a while.

  


  This is the config.json file just in case you wanna test the code and can't find it

• JavaCV Create Compatible MP4

  15 juin 2017, par Hamish258

  Trying to modify JavaCV 3.2.0 sample https://github.com/bytedeco/javacv/blob/master/samples/WebcamAndMicrophoneCapture.java, to produce an mp4 that quicktime on macOS 10.12.5 can use. Output mp4 works fine with VLC but for the software I’m producing I’d like to minimise users having to install additional products.

  The sample code produces the following output

  [libx264 @ 0x7f927794e200] using cpu capabilities: MMX2 SSE2Fast SSSE3 SSE4.2 AVX
[libx264 @ 0x7f927794e200] profile Constrained Baseline, level 3.1
[libx264 @ 0x7f927794e200] 264 - core 148 - H.264/MPEG-4 AVC codec - Copyleft 2003-2016 - http://www.videolan.org/x264.html - options: cabac=0 ref=1 deblock=0:0:0 analyse=0:0 me=dia subme=0 psy=1 psy_rd=1.00:0.00 mixed_ref=0 me_range=16 chroma_me=1 trellis=0 8x8dct=0 cqm=0 deadzone=21,11 fast_pskip=1 chroma_qp_offset=0 threads=4 lookahead_threads=4 sliced_threads=1 slices=4 nr=0 decimate=1 interlaced=0 bluray_compat=0 constrained_intra=0 bframes=0 weightp=0 keyint=60 keyint_min=6 scenecut=0 intra_refresh=0 rc=crf mbtree=0 crf=28.0 qcomp=0.60 qpmin=0 qpmax=69 qpstep=4 ip_ratio=1.40 aq=0
Output #0, mp4, to 'alatest.mp4':
 Metadata:
   encoder         : Lavf57.56.100
   Stream #0:0: Video: h264 (Constrained Baseline) ([33][0][0][0] / 0x0021), yuv420p, 1280x720, q=2-31, 2000 kb/s, 15360 tbn
   Stream #0:1: Audio: aac (LC) ([64][0][0][0] / 0x0040), 44100 Hz, stereo fltp, 192 kb/s

  The constrained baseline to 3.1 should produce usable mp4 according to https://trac.ffmpeg.org/wiki/Encode/H.264

  If I use the command line ffmpeg -i alatest.mp4 -pix_fmt yuv420p alantest.mp4 it produces a usable mo4, even though as you can see above yuv420p is the pixel format in use so there’s something else I don’t understand, the code snippet from the sample link is :

     FFmpegFrameRecorder recorder = new FFmpegFrameRecorder("alatest.mp4",1280, 720, 2);
   recorder.setInterleaved(true);
   recorder.setVideoOption("tune", "zerolatency");
   recorder.setVideoOption("preset", "ultrafast");
