rust rust-av multimedia video audio examples

examples's Introduction

Rust-AV

Pure-rust implementation of multimedia primitives and eventually some examples of demuxers, muxers and codecs.

Compiling

cargo build --workspace

Running tests

cargo test --workspace

Examples

Examples can be found in the examples repository.

Notes

The code is still in flux and the API is getting slowly fleshed out, please refer to the sub-crates. Until we reach version 1.0 assume that the API could change a lot.

Developing

I suggest to use the cargo paths override to have a local rust-av:

# Clone the trees
$ git clone https://github.com/rust-av/rust-av
$ git clone https://github.com/rust-av/${other package}
# Setup the override
$ cd ${other package}
$ mkdir .cargo
$ echo 'paths=["../rust-av"]' > .cargo/config
# Check it is doing the right thing
$ cargo build

Current master does not build

I am tring to build bca2a6c under Mac OS and see these errors when running cargo build --all. I have similar errors when trying to compile https://github.com/rust-av/avp.

can't build on windows

My Environment:
Windows 10 1809
Visual studio 2022
vcpkg commit 6a29f32
libvpx & opus installed with vcpkg:
libvpx:x64-windows 1.11.0#1

I have tried some ffmpeg binding crates with vcpkg and succeed, so the vcpkg settings would be correct.
when I run "cargo build", it shows
