hlsdl's Introduction

HLS downloader

This is a library to support downloading a m3u8 file. All TS segments will be downloaded into a folder and then joined into a single TS file. The default file name is video.ts

Features:

Concurrent download segments with multiple http connections
Decrypt HLS-encoded segments
Auto-retry download
Display downloading progress bar
Record a live stream video

Todo:

Allow adding http headers

How to integrate this library into your code

Get the library

go get github.com/canhlinh/hlsdl

then import it to your code.

import "github.com/canhlinh/hlsdl"

Sample:

package main

import (
	"fmt"

	"github.com/canhlinh/hlsdl"
)

func main() {
	hlsDL := hlsdl.New("https://bitdash-a.akamaihd.net/content/sintel/hls/video/1500kbit.m3u8", nil, "download", 64, true, "")
	
	filepath, err := hlsDL.Download()
	if err != nil {
		panic(err)
	}

	fmt.Println(filepath)
}

How to build a console application

Build for linux

make build-linux

Build for windows

make build-windows

Run the application

./bin/hlsdl --help

./bin/hlsdl -u https://bitdash-a.akamaihd.net/content/sintel/hls/video/1500kbit.m3u8 -d download -w 10

Record a live stream video

./bin/hlsdl --url "http://cdn1.live-tv.od.ua:8081/bbb/bbbtv-abr/bbb/bbbtv-720p/chunks.m3u8?nimblesessionid=62115268" --record true

hlsdl's Issues

Error: Get data:text/plain;base64,xxxxxxxxxx=: unsupported protocol scheme "data"

All the segments seemed to download successfully but got an error during merging.

Downloading... 2m35s 269 / 269 100.00% 2m35s
Joining segments
Error: Get data:text/plain;base64,xxxxxxxxxx=: unsupported protocol scheme "data"

The xxxxxxxxxx is a long string of alphanumeric characters. I'm not sure if it contains sensitive information so I redacted it for now.
Hoping someone can help. Thank you!

Multiple stream playlist support

The library does not work with multiple stream playlists, raising "No support the m3u8 format" error

Default value for IV should be Media Sequence Number

In section 5.2 of RFC8216, it states that

An EXT-X-KEY tag with a KEYFORMAT of "identity" that does not have an
IV attribute indicates that the Media Sequence Number is to be used
as the IV when decrypting a Media Segment, by putting its big-endian
binary representation into a 16-octet (128-bit) buffer and padding
(on the left) with zeros.

However, in decrypt.go,
the IV is simply set to the key, instead of the Media Sequence Number of the segment.

Help me, Please, to have hlsdl binaries (executables for Windows)!!!

Please, could someone tell me where I can find regularly updated binaries (windows executables versions) (like source files are regularly updated), of this perfect program?

Please, HELP me!!!!!

Not able to specify raw AES key value (hexstring) while downloading

I want to download a video file having m3u8 file content

Here AES Decryption key is hidden in the site code so I want to pass that decryption key explicitly so is it possible to do that.

Please I would request you if it is not possible than can you please provide me reference of other tools that provide this functionality. Thanks a lot for the help @canhlinh
