ABComposer Sample for PallyCon DRM CLI Packager

This app is a sample program that composes DASH / HLS / CMAF streams to enable Pallycon Forensic Watermark.

Requirements

This app is implemented to support the following cases:

• Input media
  • preprocessed by the PallyCon Forensic Watermark Preprocessor SDK or FFmpeg Preprocessor Filter
  • packaged by the PallyCon DRM CLI Packager
• CDN Embedder
  • Akamai Adaptive Media Delivery Watermarking
    • Notice: It does not support CMAF.
  • AWS CloudFront CDN and AWS CloudFront Embedder by PallyCon

The other cases are not considered.

Environments

Python 3.6

Usage

Simply run it as follows:

python3 ABComposer.py <stream dir 0> <stream dir 1> <target dir> [--remove_src] [--overwrite]

As a default, it copies the sources to the target and keeps the sources. If you want to remove the sources after composing, you can use --remove_src option. It moves the sources instead copying and removes remainings.

And if the <target dir> already exists, it exits without composing. If you use --overwrite, it overwrites the <target dir>.
