Automated installation script of MediaSPIP
25 avril 2011, parTo overcome the difficulties mainly due to the installation of server side software dependencies, an "all-in-one" installation script written in bash was created to facilitate this step on a server with a compatible Linux distribution.
You must have access to your server via SSH and a root account to use it, which will install the dependencies. Contact your provider if you do not have that.
The documentation of the use of this installation script is available here.

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 !

Ffmpeg x265 error : "Color Primaries must be", "ransfer Characteristics must be", "Matrix Coefficients must be" [closed]
16 septembre 2022, par Mister SirI'm trying to do the following conversion :

This works fine except for a specific video. I'm getting the following output :

I'm not an expert at video encoding, so I don't really know what this all means. Probably something with the source file. How to get around this ? Thanks in advance ! If I need to upload the video, let me know how I can do that.

how to remux/fix video file saved with testdisk that reports error "Invalid NAL unit size"
18 août 2022, par LukaI have deleted a video file from an SD card and then 'undeleted' it with tool called testdisk for Linux. It saved complete file (6Gb), but video seems broken (can't be played by any video players) and ffprobe reports :

I'm no programmer, but have used ffmpeg a lot. How can I remux (or even re-encode) such file to fix this and make the file usable for further work ?


I have created a 10seconds snippet with
ffmpeg -i MVI_1399.MP4 -t 00:00:10 -c copy MVI_1399_10sec.mp4for anyone to check. I also created a ten second snippet from a functioning clip from the same camera (I presume same codec parameters etc) :
