• Server side video merging with FFmpeg through oline form

  1er août 2017, par San007

  I have a difficult problem and not enough knowledge to solve it, therefore I am hoping you guys can give me some advice or redirect me to a professional or professional software which can solve my problem.

  I want something fairly simple but I simply do not know how to begin. I Googled extensively but didnt find any related topics.

  What do I want ?
  I want an online form on my website where people can select different options, which are videos, for example
  Question 1
  1 (1.mp4) / 2 (2.mp4) / 3 (3.mp4)
  Question 2
  X (X.mp4) / Y (Y.mp4) / Z (Z.mp4)
  Question 3
  Email adres :
  Generate

  When the visitor clicks the generator button it should merge the video’s the customer has selected. e.g. 1 and X will result in one video file of 1.mp4 and X.mp4 merged. The system should then after succesfully merging the videos send a download link to the users e-mail adres and ideally delete the video from the server afterwards.

  I know I have not done a whole lot of research because my knowledge simply is not enough to create my own solution, but I hope you guys can send me in the right direction, I do not mind any commercial solution.

• FFMPEG Jar Library and Executable [on hold]

  27 juillet 2017, par NPE

  Currently working on FFMPEG library to create timelapse-based video creator application. Our application build on Java Environment (*.jar) and will be running on server side.

  I used FFMPEG for video compression because JMF doesn’t support for video compression.

  After reading several question on SO and doing some research, I know FFMPEG can do video compression through this command

  ffmpeg -i a.mp4 -s 640x480 -b:v 512k -vcodec mpeg1video -acodec copy b.mp4

  Our FFMPEG version

  ffmpeg version N-86848-g03a9e6f Copyright (c) 2000-2017 the FFmpeg developers
  
  built with gcc 7.1.0 (GCC)
  
  
  
  windows environment (*.exe)

  My question,

  1. Is there any FFMPEG jar file or library so we can call inside from our application (our code) instead of using ProcessBuilder to call exe ?
  2. Is FFMPEG provide jar executable version ? After doing some research here I not found any executable jar. We need call executable jar like this java -jar FFMPEG.jar
  3. How to packed all jar on library so when we build application will not produce any lib folder.

  Anyway, thanks.

• Discord slash command music bot stops playing unexpectedly

  29 juillet 2023, par Shelby

  This is a bot I am using to play music and it worked just fine for a while until it didn't. Simply loaded the bot and played for about a minute and quits. From what I see it destroys the entire queue of songs, no matter how many are there. And after that it won't respond to any command and it needs to be reloaded. I don't get any error in the terminal and all the other commands seem to work just fine. Also, this happens to whatever query I use, whether it's 'search', 'url' or 'playlist'.

  


  const { SlashCommandBuilder } = require("@discordjs/builders")
const { EmbedBuilder } = require("discord.js")
const { QueryType } = require("discord-player")

module.exports = {
    data: new SlashCommandBuilder()

                .addStringOption((option) => option.setName("url").setDescription("url-ul melodiei").setRequired(true)))
        .addSubcommand((subcommand) =>

            }
            if (!queue.playing) await queue.play()
            await interaction.editReply({
                embeds: [embed]
            })
                
        }
}


  


  This is the code for the [play] command. No change was done since it worked perfectly.

  


  After some research I found out that there might be a problem with the ffmpeg or the ytdl. I tried updating or reinstalling them, but the problem still remains. I would like to know if I'll need to rework the bot to find an alternative to these two.
