HLSMaker

HLSMaker is a library that helps create HLS (HTTP Live Streaming) video segments from a source file. HLS is a protocol for distributing video over the internet.

Installation

Install the library from npm:

npm install hls-maker

Usage

Using Promises

import { HLSMaker, HLSMakerConfig } from 'hls-maker';

const options: HLSMakerConfig = {
    sourceFilePath: 'path/to/source/video.mp4',
    // Other options as per your requirements
};

const hlsMaker = new HLSMaker(options);

// Start the conversion process
hlsMaker.conversion(progress => {
    console.log(`Progress: ${progress.percent}%`);
}).then(() => {
    console.log('Conversion completed');
}).catch(error => {
    console.error('Error:', error);
});

Using async/await

import { HLSMaker, HLSMakerConfig } from 'hls-maker';

const options: HLSMakerConfig = {
    sourceFilePath: 'path/to/source/video.mp4',
    // Other options as per your requirements
};

async function convertVideo() {
    const hlsMaker = new HLSMaker(options);

    try {
        await hlsMaker.conversion();
        console.log('Conversion completed');
    } catch (error) {
        console.error('Error:', error);
    }
}

convertVideo();

Concatenating HLS Streams

You can concatenate HLS streams using the concat method. This method combines multiple HLS streams into a single stream.

Using callback function

import { HLSMaker, ConcatConfig } from 'hls-maker';

const options: ConcatConfig = {
    sourceFilePath: 'path/to/first/video.mp4',
    hlsManifestPath: 'path/to/concatenated/output.m3u8',
    isLast: true // Set to true if this is the last stream in the sequence
};

HLSMaker.concat(options, function (process) {
    console.log("Processing", process);
});

Using async/await

import { HLSMaker, ConcatConfig } from 'hls-maker';

const options: ConcatConfig = {
    sourceFilePath: 'path/to/first/video.m3u8',
    hlsManifestPath: 'path/to/concatenated/output.m3u8',
    isLast: true // Set to true if this is the last stream in the sequence
};

async function concatVideos() {
    try {
        await HLSMaker.concat(options);
        console.log('Concatenation completed');
    } catch (error) {
        console.error('Error:', error);
    }
}

concatVideos();

Insert HLS Streams

You can insert HLS streams using the insert method. This method combines multiple HLS streams into a single stream.

await HLSMaker.insert({
    hlsManifestPath: 'path/to/first/output.m3u8',
    sourceHlsManifestPath: 'path/to/source/input.m3u8',
    spliceIndex: 10 // insert from segment index
    splicePercent: 30// insert from segment percent
});

Options

HLSMakerConfig

• sourceFilePath (required): Path to the source file.
• hlsStartTime: Start time for segmenting in HLS.
• hlsDuration: Duration of the segment for HLS.
• hlsManifestPath: Path to the HLS manifest file after segmenting.
• hlsSegmentDuration: Duration of each segment (in seconds).
• hlsListSize: Manifest list size.
• appendMode (required): Append mode for segments.
• endlessMode (required): Endless mode (no termination).

ConcatConfig

• sourceFilePath (required): Path to the source file of the first segment.
• hlsManifestPath (required): Path to the output manifest file after concatenation.
• isLast (required): Set to true if this is the last stream in the sequence.
