[Release] ssadecrypt - Tool for SAMPLE-AES Decryption of MPEG-TS File

[Yesterday17]

Hi everyone,

I’d like to introduce ssadecrypt, a simple tool to decrypt MPEG-TS files encrypted using SAMPLE-AES.

Why ssadecrypt

As far as I know, there is currently no tool for this situation:

• mp4decrypt – It doesn’t support MPEG-TS inputs and only supports encrypting with SAMPLE-AES when using mp42hls.
• shaka-packager – It doesn’t support SAMPLE-AES decryption.
• ffmpeg – Although it supports SAMPLE-AES decryption, it is tied to HLS and cannot be used separately.

So, I created this tool for my own needs and hope it can help others with similar requirements.

Usage

You can download the release from GitHub Release. After downloading the tool for your platform, run a command like this:

ssadecrypt --key 1234567890abcdef1234567890abcdef --iv 1234567890abcdef1234567890abcdef input.ts output.ts

And you'll get the decrypted output.

Hope you like it.

what advantages using this new tool instead N_m3u8DL-RE ?

N_m3u8DL-RE doesn't support decrypting SAMPLE-AES, while ssadecrypt can handle decrypting the encrypted blocks downloaded by it.

If you're talking about iori - which shares its repo with ssadecrypt - it's more like a toolkit for developers to build CLI tools similar to N_m3u8DL-RE and Minyami. So if you want to customize or create your own downloader, iori is designed exactly for that.

yes i talk about ssadecrypt.
RE can't support aes encryption ? are you sure ?

Yes. There is an open issue about it.
