Rust-Written Stateless Codec Drivers Make A Lot Of Sense
![MULTIMEDIA](/assets/categories/multimedia.webp)
Daniel Almeida with Collabora plead the case for Rust stateless codec drivers in V4L2 at the FOSDEM conference this past weekend in Brussels. He's been working on Rust bindings for the V4L2 kernel code and as an initial proving grounds for the benefits of Rust in this space he's been working toward bringing the VISL virtual codec driver from C to Rust.
The VISL virtual driver as-is is beneficial for working on new user-space features, fixing user-space bugs, testing, and prototyping new codec APIs. This virtual stateless decoder driver should also be rather simple in writing a Rust implementation compared to a real and complex hardware driver.
Those wanting to learn more about this effort on getting Rust code happening within Linux's V4L2/codec space can see the FOSDEM presentation for more details.
