Nodejs ffmpeg "The input file path can not be empty" error, but files exist
29 octobre 2022, par 0sziI'm trying to merge an audio file with a video file from the same source (Youtube)


In the following code I first read in the console parameters wirh commander then i define the videoOutput dir and download the highset res. video from youtube with node-ytdl-core. After that I download the audio for the video. and in the callback of the video.on("end", ....)
i call the function merge()


const path = require('path');
const fs = require('fs');
const readline = require("readline");
const ytdl = require('ytdl-core');
const { program } = require('commander');
const ffmpeg = require('ffmpeg');

program
 .option("--url, --url <url>", "Youtube video url")
 .option("--name, --name <name>", "Name of the video in hard drive")

program.parse(process.argv);


const options = program.opts();
let url = options.url;
let name = options.name;

let videoOutput = path.resolve(`./video${name}.mp4`);

let video = ytdl(url, {
 quality: "highestvideo"
});

let starttime = 0;

video.pipe(fs.createWriteStream(videoOutput));

video.once('response', () => {
 starttime = Date.now();
});

video.on('progress', (chunkLength, downloaded, total) => {
 const percent = downloaded / total;
 const downloadedMinutes = (Date.now() - starttime) / 1000 / 60;
 const estimatedDownloadTime = (downloadedMinutes / percent) - downloadedMinutes;
 readline.cursorTo(process.stdout, 0);
 process.stdout.write(`${(percent * 100).toFixed(2)}% downloaded `);
 process.stdout.write(`(${(downloaded / 1024 / 1024).toFixed(2)}MB of ${(total / 1024 / 1024).toFixed(2)}MB)\n`);
 process.stdout.write(`running for: ${downloadedMinutes.toFixed(2)}minutes`);
 process.stdout.write(`, estimated time left: ${estimatedDownloadTime.toFixed(2)}minutes `);
 readline.moveCursor(process.stdout, 0, -1);
 });

 video.on('end', () => {
 process.stdout.write('\n\n');
 });


// repeat for audio
video = ytdl(url, {
 quality: "highestaudio"
});
 
starttime = 0;

let audioOutput = path.resolve(`./audio${name}.mp3`);

video.pipe(fs.createWriteStream(audioOutput));

video.once('response', () => {
 starttime = Date.now();
});

video.on('progress', (chunkLength, downloaded, total) => {
 const percent = downloaded / total;
 const downloadedMinutes = (Date.now() - starttime) / 1000 / 60;
 const estimatedDownloadTime = (downloadedMinutes / percent) - downloadedMinutes;
 readline.cursorTo(process.stdout, 0);
 process.stdout.write(`${(percent * 100).toFixed(2)}% downloaded `);
 process.stdout.write(`(${(downloaded / 1024 / 1024).toFixed(2)}MB of ${(total / 1024 / 1024).toFixed(2)}MB)\n`);
 process.stdout.write(`running for: ${downloadedMinutes.toFixed(2)}minutes`);
 process.stdout.write(`, estimated time left: ${estimatedDownloadTime.toFixed(2)}minutes `);
 readline.moveCursor(process.stdout, 0, -1);
 });


function merge(){
 ffmpeg()
 .input("./videotest.mp4") //your video file input path
 .input("./audiotest.mp3") //your audio file input path
 .output("./finished.mp4") //your output path
 .outputOptions(['-map 0:v', '-map 1:a', '-c:v copy', '-shortest'])
 .on('start', (command) => {
 console.log('TCL: command -> command', command)
 })
 .on('error', (error) => console.log("errrrr",error))
 .on('end',()=>console.log("Completed"))
 .run() 
}

video.on('end', () => {
 process.stdout.write('\n\n');
 merge();
});

</name></url>

But even though the files are there ffmpeg throws me this error :



I also tried this in the video-end callback, because maybe the audio is finished downloading before the video, still doesn't work. I've also tried to rename the outputDirs for the files and keep the old files and rerun the script so the files are 100% there. Still doesn't work.


I have also tried absolute paths ("C :/..." also with backslash "C :\...") but I still get the error message that the input file path can't be empty.


Appreciate any piece of advise or help !

Python yt-dlp and ffmpeg error "merging of multiple formats but ffmpeg is not installed"
27 mai, par T Tea TieI am using the latest version of
yt-dlpwith Python 3.9.

I am trying to download a youtube video in mp4 format with outputname as the
youtubeid.mp4and with best resolution not more than 4K.

This is my Python code :


ytid = '4cDqaLxrt6Q'
url = 'https://www.youtube.com/watch?v='+ytid
output_filename = ytid+".mp4"
 
with YoutubeDL({'format': 'bestvideo[height<=?4K]+bestaudio/best', 'output': output_filename}) as ydl:
 ydl.download(url)`#TODO debug FFmpeg and check if outputname is ok


I expected to have an
.mp4file in my current working directory.

Then I installed the latest version of
FFmpegfromffmpeg-master-latest-win64-gpl.zipand putffmpeg.exe,ffplay.exeandffprobe.exein Scripts python folder (whereyt-dlp.exeis). I also installedffmpegusingpip install.

The

FFMPEG Kit issue in Banuba Video SDK : "FFmpegKit failed to start on brand"
10 mai 2023, par Vivek MakwanaI am trying to integrate Banuba Video Editor sdk in flutter.


The issue i am facing is as below


Banuba sdk works with native code for Android in Flutter


So Banuba requires FFMPEG dependency to define in Native Android


And I am already using 'ffmpeg_kit_flutter' plugin for flutter.


So both the FFMPEG kits are conflicted and some of the functions are not found. due to that I am receiving the below error.


When the app is launched I am receiving this Crash as mentioned


**java.lang.Error: FFmpegKit failed to start on brand: google, model: sdk_gphone_x86, device: generic_x86_arm, api level: 30, abis: x86 armeabi-v7a armeabi, 32bit abis: x86 armeabi-v7a armeabi, 64bit abis: .
