Automated installation script of MediaSPIP

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.

Ffmpeg Error : Error opening output file .output_withsrt.mp4
13 juin 2024, par Priyanshu TiwariI'm building a video caption writer web app, for embedding subtitle in a video I'm using ffmpeg.


But there is a error opening output file, everything is working fine in a cmd, but in VS Code it's not working.


My code :


import ffmpeg from "fluent-ffmpeg";
import { NextRequest } from "next/server";

ffmpeg.setFfmpegPath('C:\\ffmpeg\\bin\\ffmpeg.exe')

export async function POST(req: NextRequest) {
 try {
 const videoWithSubtitlesPath = path.join(
 process.cwd(),
 "public",
 "subtitle_video.mp4"
 );

 console.log(videoWithSubtitlesPath)
 console.log("yaha tak");

 await embedSubtitle(
 "http://res.cloudinary.com/dptgkunzk/video/upload/v1717785028/w8ezkazwhsqbyx7f34rw.mp4",
 "@/public/srtfile/output.srt",
 "./public/srtfile/giveme.mp4"
 );

 console.log("calling")
 } catch (error) {
 console.log("Something went wrong while adding subtitle");
 }

 return Response.json({ message: "done" });
}

async function embedSubtitle(videopath: string, srtFilePath: string, outputPath: string): Promise<any>{
 if(!videopath || !srtFilePath || !outputPath) return false

 try {
 await new Promise<void>((resolve, reject) => {
 ffmpeg()
 .input(videopath)
 .videoFilters(`subtitles = ${srtFilePath} : force_style='Fontsize=24'`)
 .output("./output_withsrt.mp4")

 .on("end", () => {
 console.log("Subtitle added successfully");
 resolve()
 })

 .on("error", (err, stderr) => {
 console.error("Error during conversion and subtitle adding", err)
 console.error("stderr", stderr)
 reject(err);
 })
 .run()
 })
 return true
 } catch (error) {
 console.log("error while embedding subtile in a vidoe")
 }
}
</void></any>

Error :

Moving .wav files from S3 to /tmp folder in AWS Lambda
1er août 2019, par sleepyrobotI am currently trying to overlay two .wav files from S3 in AWS Lambda using FFMPEG. I am using node.js to do this. Here’s my process :
- Retrieve the files from S3, and save it to the Lambda /tmp folder
- Merge the two audio files, and save the output to the /tmp folder
- Upload the output from /tmp folder to S3.
However, I am encountering errors on the first part, since the .wav files being downloaded are corrupted and distorted.
I have tried using streams for this. However, I am still grasping its concept. I would appreciate any help. For my first try, I tried to retrieve an object from S3 and reupload the same
I have tried using function for getting the audio file from S3 :
async function readIn(bucketName, inputFilename, transfer, local) {
console.log('reading in locally?', local);
console.log(`reading from ${inputFilename} to ${transfer}`);
// inputFilename is the key name (object name)
// transfer is the filepath to where the obj will be transferred to (example: /tmp/audio1.wav)
const writeStream = fs.createWriteStream(transfer);
var file;
local? await new Promise((resolve, revoke) => {
file = fs.createReadStream(inputFilename);
writeStream.on('finish', () => {
console.log('file finished reading');
resolve();
});
writeStream.on('error', (err) => {
console.log('things messed up');
revoke();
});
file.pipe(writeStream);
}) : await new Promise((resolve, revoke) => {
writeStream.on('finish', () => {
console.log('file finished reading');
resolve();
});
writeStream.on('error', (err) => {
console.log('things messed up');
revoke();
});
s3.getObject({
Bucket : bucketName,
Key : inputFilename
}, function(err, data) {
if (err) {
console.log(err, err.stack);
} else {
console.log('data got!');
}
}).createReadStream().pipe(writeStream);
});
console.log('returning to main from reading');
return;
}For uploading the file to S3 :
async function writeOut(bucketName, outFile, transfer, contentType) {
console.log('uploading', bucketName, outFile, transfer);
return s3.upload({
Bucket: bucketName,
Key: outFile,
Body: fs.createReadStream(transfer),
//ACL: 'private',
ContentType: contentType
}).promise();
}For merging the files (I haven’t tried this yet) :
async function mergeFile(transfer1, transfer2, output) {
await new Promise((resolve, revoke) => {
console.log('beginning merge');
var outStream = fs.createWriteStream('/tmp/output.wav');
childProcess.exec('cp /var/task/ffmpeg /tmp/.; chmod 755 /tmp/ffmpeg;',
function (error, stdout, stderr) {
if (error) {
console.log('[ERROR]: An error occured in altering FFMPEG permission: ', error);
} else {
console.log("[SUCCESS]: Successfully altered FFMPEG permission!");
// merge audio files
ffmpeg('/tmp/audio1.wav')
.input('/tmp/audio2.wav')
.on('error', function(err) {
console.log('An error occurred with merging: ' + err.message);
})
.complexFilter(
{
filter: 'amix',
inputs: ['0:a','1:a']
})
.on('end', function() {
console.log('Merging finished!');
})
.pipe(outStream, { end: true });
//.save('/tmp/output.wav');
//////
}
})
});}However, the resulting file is corrupted. Is there any error in the functions ? Please help. Thanks !
