dash2dash

Description

This repository serves as a proof of concept for real-time watermarking technology. It includes a simple pseudo-DASH server that resolves a local DASH manifest. A proxy server intercepts video segments and overlays text using ffmpeg to demonstrate the watermarking function.

Requirements

go1.22.1: Required for the watermarking proxy server written in Go. It may work with other versions of Go.
ruby 3.3.2: Needed to run the pseudo-DASH server. In reality, any Ruby version should suffice as it runs a basic WEBrick server.
foreman: Used to execute the Procfile, which in turn starts the demonstration.
abema/go-mp4: Go library for parsing MP4 files.
u2takey/ffmpeg-go: Go bindings for ffmpeg.
ffmpeg (version 6.1.1): Installed separately, used by the watermarking proxy server to overlay text on video segments.

Usage

To run the demonstration:

Setup:
- Clone the repository.
- Install necessary dependencies.
Download DASH Segments:
- Download the DASH segments from this Dropbox link.
Extract and Place Files:
- Unzip the downloaded file.
- Place the extracted files into the project directory under testdata/example_1/. For example, the files should be structured as follows:
```
<repo_dir>/testdata/example_1/chunk-0-00001.m4s
<repo_dir>/testdata/example_1/chunk-0-00002.m4s
...
```
Start Servers:
- Run the pseudo-DASH server:
```
ruby bin/simple_http_server.rb
```
- Start the watermarking proxy server:
```
go run cmd/cli/main.go
```
OR Run the Demonstration:
- Execute Foreman to start both servers simultaneously:
```
foreman start
```
Access the Demo:
- Open a browser or media player that supports DASH streaming and navigate to the demo URL (http://localhost:8000/manifest.mpd)
