I want to make a live video streaming API and send the video buffer chunk data to an HTML. I am using rtsp URL. The chunk logic does not work. The video only plays for 5 seconds then stops.
index.js file
const express = require('express');
const ffmpeg = require('fluent-ffmpeg');
const fs = require('fs');
const path = require('path');
const app = express();
const port = 3000;
app.get('/', (req, res) => {
res.sendFile(__dirname + "/index.html");
});
const rtspUrl = 'rtsp://zephyr.rtsp.stream/movie?streamKey=64fd08123635440e7adc17ba31de2036';
const chunkDuration = 5; // Duration of each chunk in seconds
app.get('/video', (req, res) => {
const outputDirectory = path.join(__dirname, 'chunks');
if (!fs.existsSync(outputDirectory)) {
fs.mkdirSync(outputDirectory);
}
const startTime = new Date().getTime();
const outputFileName = `chunk_${startTime}.mp4`;
const outputFilePath = path.join(outputDirectory, outputFileName);
const command = ffmpeg(rtspUrl)
.inputFormat('rtsp')
// .inputOptions(['-rtsp_transport tcp'])
.videoCodec('copy')
.output(outputFilePath)
.duration(chunkDuration)
.on('start', () => {
console.log(`start ${outputFileName}`);
})
.on('end', () => {
console.log(`Chunk ${outputFileName} saved`);
res.setHeader('Content-Type', 'video/mp4');
res.sendFile(outputFilePath, (err) => {
if (err) {
console.error('Error sending file:', err);
} else {
fs.unlinkSync(outputFilePath); // Delete the chunk after it's sent
}
});
})
.on('error', (error) => {
console.error('Error: ', error);
});
command.run();
});
app.listen(port, () => {
console.log(`API server is running on port ${port}`);
});
