asr

Adaptive Stream Recorder (asr) is a simple recorder for adaptive media streaming protocols.

Features

At the moment only HTTP Live Streaming (HLS) is supported. If a master playlist is passed to the program, the stream with the highest bandwidth is chosen.

asr is a simple alternative to a FFmpeg command line such as:

ffmpeg -i <URL> -c copy <output file>

Getting Started

Prerequisites

To build asr, the minimum software version requirements are CMake 3.18.0, Boost 1.80.0, OpenSSL 3.0.0, and a C++17 compiler. In addition, liburing 2.1 is required on Linux, while on Windows Boost must be compiled with the _WIN32_WINNT macro set to 0x0A00.

The runtime operating system requirements are Linux 5.15, macOS 12.5 (Monterey), or Windows 11.

Building

Often it is sufficient to run:

mkdir build
cd build
cmake ..
cmake --build .

If CMake is unable to find any dependency, refer to CMake's (and possibly the compiler's) documentation for the necessary options to specify the location.

Installing

To install, continue with:

cmake --install .

Usage

Run asr without any parameters to obtain the usage information.
