• How do I get videoshow (or any other js package) to merge image and sound files to the length I specify rather than a constant length of 5 seconds ?

  5 décembre 2023, par Bragon

  I’m trying to take an image file and a sound file and merge them together into an mp4 file. To this end, I use videoshow.js which is basically a wrapper for fluent-ffmpeg.js. For some reason, videoshow always sets the duration of the output file to 5 seconds regardless of what I set the loop parameter to. And to top it all off, it fades out the sound towards the end of the clip.

  


  I’m happy for any solution to this even if it doesn’t include the use of videoshow or fluent-ffmpeg.

  


  const url = require('url');
const { smartLog } = require('../services/smart-log');
const { getFile, getDuration } = require('../services/file-service');
const videoshow = require('videoshow');
const path = require('path');
const FFmpeg = require('fluent-ffmpeg');
const fs = require('fs');

const imgToMP4 = (caption, sound, image, duration, output) => {
  smartLog('info', `Converting ${image}`);
  const images = [image];

  const videoOptions = {
    fps: 10,
    loop: duration,
    transition: false,
    videoBitrate: 1024,
    videoCodec: 'libx264',
    size: '640x?',
    audioBitrate: '128k',
    audioChannels: 2,
    format: 'mp4',
    pixelFormat: 'yuv420p',
  };

  videoshow([
    {
      path: image,
    },
  ])
    .audio(sound)
    .save(output)
    .on('start', function (command) {
      smartLog('info', `ffmpeg process started: ${image}`);
    })
    .on('error', function (err) {
      smartLog('error', err);
    })
    .on('end', function (output) {
      smartLog('info', `Video created: ${output}`);
    });
};



  


• How do I make my discord.py bot play a sound effect ?

  15 mai 2024, par Kronik71

  My bot is supposed to be some sort of jeopardy quiz show type of bot. /joinvc makes the bot connect to the call, however, I cant seem to make the bot make noise when its in a vc. Here's some of the code :

  


  @interactions.slash_command(
    name="press",
    description="Press the button"
)

async def press(ctx: interactions.ComponentContext):
    await ctx.send(f"{ctx.author.mention} has pressed the button")
    vc = ctx.author.voice.channel
    player = vc.create_ffmpeg_player('audiopath', after=lambda: print('done'))
    player.start()


  


  But whenever I use the /press command, I get this error AttributeError: 'GuildVoice' object has no attribute 'create_ffmpeg_player'

  


  Is it something I did wrong with ffmpeg ?

  


  I tried using a different way to write the code, basically grabbing the ffmpeg.exe path and the audio path, didn't work either. I just want the bot to play a small noise whenever someone uses /press command.

  


• Delay Issue in Screen Recording with Sound Using FFmpeg

  17 novembre 2023, par Vasilis B.

  I'm currently facing a puzzling issue with FFmpeg during screen recording sessions where I've noticed a small but noticeable delay when adding sound. I'm hoping to tap into the community's expertise to understand what might be causing this and how to resolve it.

  


  Here's the command I'm using :

  


  ffmpeg -f dshow -thread_queue_size 1024 -rtbufsize 100M -i "video=screen-capture-recorder:audio=virtual-audio-capturer" -f dshow -c:v h264_nvenc -g 30 -qp 10 -preset llhq -tune ull -pix_fmt yuv420p -vsync vfr -acodec libmp3lame -f rtsp "rtsp://rtsp-server:8554/stream"
This setup is intended to capture both video and audio for streaming purposes. However, I've noticed a small delay (output latency) in the audio when I add the sound component.

  


  


  q=9.0 size=N/A time=00:00:14.36 bitrate=N/A speed=0.998x

  


  


  Here are some specifics :

  


  The delay isn't present when recording video only.

  


  It's a consistent issue regardless of the streaming destination.

  


  The hardware and software environment hasn't shown similar issues with other applications.

  


  Could this delay be related to the way FFmpeg handles the audio and video synchronization, or might it be a hardware-related issue ?

  


  Are there specific FFmpeg flags or settings that could help mitigate this delay ?

  


  Has anyone else experienced similar issues and found workable solutions ?

  


  Any insights, suggestions, or shared experiences would be greatly appreciated. Thanks in advance for your help !

  


  P.S. : If additional details about my setup or configuration are needed, I'm happy to provide them.

  


  I've experimented with different -thread_queue_size and -rtbufsize values but haven't seen significant improvements.
