One way to protect HLS content is by using encryption, which ensures that the content can only be accessed by authorized users. • There are several ways to implement content protection for HLS, including the use of Secure HLS (S-HLS) or DRM (Digital Rights Management) systems. S-HLS is a variant of HLS that adds an additional layer of encryption to the content, using AES (Advanced Encryption Standard) or SAMPLE-AES encryption. This helps to prevent unauthorized access to the content by encrypting it with a secret key that is known only to the authorized users. • AES (Advanced Encryption Standard) is a widely used symmetric encryption algorithm that is used to secure data by encrypting it with a secret key. It is a fast and secure algorithm that has been adopted as a standard by the US government, as well as by many other organizations and businesses around the world. • In the context of HLS (HTTP Live Streaming), AES encryption is often used to secure the content that is delivered over the internet. When HLS content is encrypted with AES, it is encrypted with a secret key that is known only to the authorized users. This helps to prevent unauthorized access to the content, as it can only be decrypted and accessed by users who have the correct key. • SAMPLE-AES is another encryption algorithm that is often used in HLS. It is a variant of AES that uses a similar encryption process, but it is specifically designed for use with HLS. It is designed to be efficient and easy to implement, and it is commonly used to encrypt audio and video content in HLS streams. • Overall, AES and SAMPLE-AES are important encryption algorithms that are used to secure HLS content and protect it from unauthorized access. They help to ensure that only authorized users can access the content, and they provide a high level of security for the data being transmitted. • In this quick tutorial, I tried to explain how content protection works in HTTP live streaming. HLS uses AES 128 symmetric encryption with 16 bites of key. • First we generated a random key with openssl, then segmented the video along with encrypting it. HLS player always need the key to decrypt and play the video. • Excuse me for my bad English. Hope you have learned something new regarding http live streaming form this tutorial. • To learn more about HLS: https://developer.apple.com/streaming/ • https://ffmpeg.org/ffmpeg-formats.htm... • the main command for ffmpeg is as follows. • ffmpeg -y -i 1.mp4 -preset slow -g 48 -sc_threshold 0 -map 0:0 -map 0:1 -map 0:0 -map 0:1 -map 0:0 -map 0:1 -map 0:0 -map 0:1 -map 0:0 -map 0:1 -map 0:0 -map 0:1 -s:v:0 1920*1080 -b:v:0 1800k -s:v:1 1280*720 -b:v:1 1200k -s:v:2 858*480 -b:v:2 750k -s:v:3 630*360 -b:v:3 550k -s:v:4 426*240 -b:v:4 400k -s:v:5 256*144 -b:v:5 200k -c:a copy -var_stream_map v:0,a:0,name:1080p v:1,a:1,name:720p v:2,a:2,name:480p v:3,a:3,name:360p v:4,a:4,name:240p v:5,a:5,name:144p -master_pl_name master.m3u8 -f hls -hls_time 10 -hls_key_info_file enc.keyinfo -hls_playlist_type vod -hls_list_size 0 -hls_segment_filename v%v/segment%d.ts v%v/index.m3u8 • you can customize your command based on your requirement. if you are helped with this video please consider subscribing to the channel. • The link of chrome extension: https://chrome.google.com/webstore/de...
