Unified Streaming media processing source repository

This repository contains the source code for Unified Streaming's open source media processing tools.

Repository contents

• cuti

  A shared library/DLL that provides an asynchronous RPC framework for C++, and a few other utilties for logging, command line parsing and daemonization. Distributed under the terms of the LGPLv2.1.

• usp-builder

  A build tool that is mainly used for managing the dependencies between the projects in the source tree, relying on b2 and GNU make to do the actual work. Distributed under the terms of the GPLv2.

• with_dll_dir

  A small Python-on-Windows wrapper to set the native DLL search directory for a python script. Distributed under the terms of the LGPLv2.1.

• x264

  Our fork of VideoLAN's x264 library. Distributed under the terms of the GPLv2.

• x264_encoding_service

  A daemon/service that provides x264 encoding over a TCP connection. Distributed under the terms of the GPLv2.

• x264_es_utils

  A static library providing some utilities for the x264 encoding service. Distributed under the terms of the GPLv2.

• x264_proto

  A shared library/DLL that implements both the client and server sides of the network protocol used by the x264 encoding service. Distributed under the terms of the LGPLv2.1.

Build requirements

• A recent native C++ compiler toolchain. We use g++ on Linux, and the MSVC command line tools on Windows. Decent support for C++-20 is required.

• A recent native version of b2.

• A recent version of GNU make and a few other POSIX-style command line utilities such as bash, rm, mkdir, GNU sed, and nasm. On Windows, we use a fairly minimal set of Cygwin packages to provide these tools; the resulting binaries do not depend on Cygwin.

Build instructions

From a POSIX-style shell (bash) in the top level source directory:

• type make to build all executables and shared libs/DLLs. By default, debug mode is used. For release mode, type make variant=release

• type make clean to remove all generated artifacts.

• type make unit_tests to run all unit tests.

• type make deploy dest-dir=/some/path to deploy the executables and shared libs/DLLs to the directory tree rooted at /some/path.
