tnewman / pat Goto Github PK

Automate NPM and PyPi Publishing

Need a strategy for safely tagging and updating versions.

As a PAT developer, I want to setup GitHub actions, so that PAT is built automatically and repeatably (reducing my effort).

Publish rustpat to crates.io

As a Mac OSX developer, I want PAT play back audio using Core Audio, so that I can use PAT without setting up third party C libraries.

CI should include a Windows build

The goal of PAT has always been to enable an easy, cross platform, cross language audio playback library. PAT was designed to abstract over the details of decoding and playing back audio, which usually involves interfacing with C APIs. PAT currently provides a C library to provide a simple API that can be integrated with other programming languages easily. The C library uses ffmpeg behind the scenes to provide cross platform playback.

While PAT currently provides cross-platform audio playback for Python and NodeJS, two key issues have come up:

1. Integrating the C library's CMake build system into other programming languages is not straightforward and creates friction during development.
2. The use of ffmpeg makes PAT hard for end users to setup on some platforms. PAT is easy to setup on Linux, but it is difficult to setup on other platforms, specifically Windows. Bundling ffmpeg with PAT is problematic due to its size.

To solve these issues, I am kicking off the PAT Next Gen project with the following goals:

1. Preserve the existing PAT APIs in C, NodeJS, and Python.
2. Build the C library with native language build tools (GYP for Node and setup.py for Python).
3. Provide OS native binaries on package registries, so end users can use PAT without a C compiler. This will require setting up CI/CD for the project.

PAT should support Java through JNI.

Java expects pre-built shared libraries, so these will need to be bundled for every supported platform.

CI should include a Mac OSX build

• How to install on Windows
• How to install on Mac OSX
• Rust README

As a Node developer, I want PAT to use a GYP build, so that I can build the project using the native Node build tools that I am familiar with.

Update the NodeJS example to use modern idioms, such as async/await.

pat_decode.c contains a memory leak on line 51. The decoder should be freed even in the case of error.

rust-ac-ffmpeg provides a safe wrapper around FFmpeg. This library could be greatly simplified if it were ported to Rust.

got the following error when importing pypat using anaconda environment
import _pypat
Exception: Could not open audio device. Audio playback is unsupported on this
when i use normal python3 with terminal i get this:
import _pypat
ImportError: /lib/x86_64-linux-gnu/librsvg-2.so.2: undefined symbol: cairo_tag_end
I have made sure I have SDL2,ffmpeg installed. what could've caused this ?
my code is simply import pypat

Edit: It would be better for me if i can solve this for anaconda.

As a Python developer, I want pat to officially support PyPy, so that I can choose to use a higher performance Python implementation if I choose.

Acceptance Criteria

1. pypat works with pypy3 without modification
2. pypat is tested with pypy3 in CI

Add rustpat to main README.md

As a Python developer, I want PAT to be built with setup.py, so that I do not need to install additional development tools.

As a Windows developer, I want PAT play back audio using Windows Media Foundation, so that I can use PAT without setting up third party C libraries.
