Apply multiple text filters at once and burn into video for captioning without re-encoding, and fix error [ffmpeg-python wrapper]
13 mai, par BaldiIs there any way to burn text into a video without re-encoding ? I ask this because the re-encoding process goes at around 0.1x speed on my device when writing to WEBM. Alternatively, if there is a faster way to render high quality video quickly while still re-encoding that would be great. I vaguely remember someone writing to a temporary file to solve this problem.


Also small error in program, code attatched

Capturing canvas to video in fastes way
28 novembre 2019, par Julien PlancheI’m capturing canvas which contains things like videos, images and text, but I capture each frame per frame, using the
onseekedevent to capture the next frame after seeking the video to the desired frame.
But it’s taking a long time.Is there a way to capture canvas faster ? e.g. Using GPU acceleration or dedicated software.

Issues with Discord JS Music Bot
5 décembre 2020, par ThresioI am in the process of creating a Discord bot with JS, giving it management, auto role, etc. I just got to the music section of it and I can't quite figure out whats wrong.



I believe I have installed FFmpeg correctly, as I have access to it from within the terminal. I have also used npm to bring ytdl-core and opusscript into my program.



What this should do is make the bot join the chat, then play the Youtube link. Currently, I am not error checking the second argument as I just wanted to get it working initially. I have implemented several different instances of .toString() and String() however it always gives the same error listed below.



. The program still throws this error :



TypeError [ERR_INVALID_ARG_TYPE]: The "file" argument must be of type string. Received type object
TypeError [ERR_INVALID_ARG_TYPE]: The "file" argument must be of type string. Received type object

abort(TypeError [ERR_INVALID_ARG_TYPE]: The "file" argument must be of type 
string. Received type object). Build with -s ASSERTIONS=1 for more info. 



Here is my code for calling play :



case 'play':

 function play(connection, message){
 var server = servers[message.guild.id];

 server.dispatcher = connection.playStream(ytdl(server.queue[0], {filter: 'audioonly'}));

 server.queue.shift();

 server.dispatcher.on('end', function(){
 if(server.queue[0]){
 play(connection, message);
 }else {
 connection.disconnect();
 }
 })
 }

 if(!args[1]){
 message.channel.send('You need to provide a link!');
 return;
 }

 if(!message.member.voiceChannel){
 message.channel.send('You must be in a voice channel to play music!');
 return;
 }

 if(!servers[message.guild.id]) servers[message.guild.id] = {
 queue: []
 }

 var server = servers[message.guild.id];

 server.queue.push(args[1]);

 if(!message.guild.voiceConnection) message.member.voiceChannel.join().then(function(connection){
 play(connection, message);
 })
 break;



If anyone could assist with this, I would be very grateful.



EDIT : I unfortunately never figured out my main issue, but I have now found code that works (unlike mine :/).
For anyone else having this issue, I suggest using the code found here.
Works like a charm !
