Shaka Player Embedded

Shaka Player Embedded is a framework that runs Shaka Player in native (C++) apps. This gives a cross-platform interface to Shaka Player allowing native apps to use the player. Your native apps can now be built with the same features, behavior, and API as your Shaka-based web apps.

In addition to the C++ API, we provide a high-level wrapper for iOS called ShakaPlayer and ShakaPlayerView which can be used from either Objective-C or Swift.

Platform support

We only support iOS at this time, but other platforms could be added.

Because many on our team use Linux, there is a Linux port included to make it easier to work on non-iOS-specific features. Linux is not, however, a first-class target platform at this time.

API/ABI compatibility

This project follows semantic versioning, meaning we maintain backwards compatibility with all minor releases, including ABI. This means you can drop in a newer version of the compiled library and not have to recompile your main app (you'll need to re-sign it due to Apple requirements).

Minor releases (e.g. v1.1) will add new features in a reverse-compatible way, but major releases (e.g. v2.0) may break any compatibility. We'll mark deprecated features with compiler attributes to give you warnings about features that will be removed later. This may break API compatibility if you compile with -Werror, but you can suppress the warnings. Features will only be removed in major releases.

Widevine support

Widevine support requires the Widevine CDM for iOS, which must be obtained separately from Widevine, under license. The Widevine CDM is not open-source.

Adding Widevine support requires compiling from source; you cannot use the pre-built versions. Follow the instructions in the Widevine CDM repo for how to build it.

This requires the use of at least v15.2.3 of the Widevine CDM.

Setting up for development

1. The source is managed by Git at https://www.github.com/shaka-project/shaka-player-embedded. You will need these tools available on your development system:

• Git v1.7.5+
• Python v2.7
  • Requires installing package enum34
• autoconf 2.57+
  • m4
  • automake 1.7+
  • perl

This does not require a C++ compiler as it uses a pre-compiled version of clang downloaded from Google Cloud Storage. However, it does require a C++11 compatible C++ library (installed with most compilers, e.g. gcc).

2. Install Chromium depot tools, which contains ninja and other required tools. See https://www.chromium.org/developers/how-tos/install-depot-tools for details.

3. Get the source

git clone https://github.com/shaka-project/shaka-player-embedded.git
cd shaka-player-embedded

We use git submodules to manage third-party dependencies. You can run git submodule update (or pass --recurse-submodules to git clone) to download all the submodules; or you can wait and have the configure script download only those you need.

4. Configure and Build

You need to run configure to setup configuration settings. You can pass --help to see some of the options you can use. We don't support in-tree builds; you need to run configure in another directory.

Once configure is done, you can build using build.py. There is a Makefile that will run the script for you if you prefer.

mkdir foo
cd foo
../configure
make

5. Copy the shared library

Once it is built, you can use the resulting shared library.

On iOS, there will be a ShakaPlayerEmbedded.framework folder that you use; there is also a ShakaPlayerEmbedded.FFmpeg.framework bundle that you need to include in your app, but you shouldn't use it directly since we don't maintain ABI for it.

On other platforms, there is a libshaka-player-embedded.dylib or a libshaka-player-embedded.so file you can use. Like iOS, there is a libshaka-player-embedded.ffmpeg.* file you need to include too.

If you are using a custom --eme-impl, you need to copy the respective shared libraries too, if needed.

Running the checks

If you intend to send a pull-request, you need to ensure the code complies with style guidelines. This is done with the shaka/tools/presubmit.py script, which can be run with make check.

To run all the checks, you also have to have clang-tidy installed. It needs to be installed on PATH, or you can pass --clang-tidy to the script to tell it where to find the binary.
