Libvda Rust wrapper

Warning: This document is old & has moved. Please update any links:

Rust wrapper for libvda. This library is used to enable communication with Chrome‘s GPU process to perform hardware accelerated decoding and encoding. It is currently in development to be used by crosvm’s virtio-video device.

Building for a CrOS board

You can build and run unittests with emerge in chroot.

# Build
(chroot)$ emerge-{BOARD} dev-rust/libvda
# Unit tests
(chroot)$ FEATURES=test emerge-{BOARD} dev-rust/libvda

Building for the host environment

You can also execute cargo directly for faster build and tests. This would be useful when you are developing this crate. Since this crate depends on, you need to install it to host environment first.

# Change host's linker to gold since host environment's default linker GNU ld
# fails to link libraries.
(chroot)$ sudo binutils-config --linker
(chroot)$ sudo emerge chromeos-base/libvda        # Install to host.
# Build
(chroot)$ cargo build
# Unit tests
(chroot)$ cargo test
