• FFmpeg lagging issue in android

  5 septembre 2012, par Balwant Kumar Singh

  I'm using FFmpeg using dolphin player. I'm getting video lagging issue and also Audio/Video synch issue for big files.

  Is there any solution to get rid of it ? I'm pretty new in this and don't have the knowledge FFmpeg code.

  I've gone through this FFmpeg tutorial site, http://dranger.com/ffmpeg/ffmpeg.html.

  With this I can understand about a little about implementing internal audio/video clock.
  I'm not able to understand, in which part of FFmpeg I should do alteration for solving this problem.

  Kindly reply with a solution...

• 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 path from 'path';

const client = new Client();

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

setStreamOpts(
    config.streamOpts.width,

    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;

  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

• VLC snytax to transcode & stream to stdout ?

  4 octobre 2016, par Will Tower

  Goal : I am trying to use VLC as a local server to expand the video capabilities of an app created with Adobe AIR, Flex and Actionscript. I am using VLC to stream to stdoutand reading that output from within my app.

  VLC Streaming capabilities
  VLC Flash Video

  Status : I am able to launch VLC as a background process and control it through its remote control interface (more detail). I can load, transcode and stream a local video file. The example app below is a barebones testbed demonstrating this.

  Issue : I am getting data in to my app but it is not rendering as video. I don’t know if it is a problem with my VLC commands or with writing to/reading from stdout. This technique of reading from stdout in AIR works (with ffmpeg for example).

  One of the various transcoding commands I have tried :

  -I rc  // remote control interface  
  
  -vvv   // verbose debuging  
  
  --sout  // transcode, stream to stdout 
  
  "#transcode{vcodec=FLV1}:std{access=file,mux=ffmpeg{mux=flv},dst=-}"

  This results in data coming into to my app but for some reason it is not rendering as video when using appendBytes with the NetStream instance.

  If instead I write the data to an .flv file, a valid file is created – so the broken part seems to be writing it to stdout. One thing I have noticed : I am not getting metadata through the stdout`method. If I play the file created with the command below, I do see metadata.

  Hoping someone sees where I am going wrong here.

  ---

  // writing to a file
  
  var output:File = File.desktopDirectory.resolvePath("stream.flv");
  
  var outputPath:String = output.nativePath;
  
  "#transcode{vcodec=FLV1}:std{access=file,mux=ffmpeg{mux=flv},dst=" + outputPath + "}");

  ---

  Note : In order to get this to work in AIR, you need to define the app profile as "extendedDesktop"
