Using userspace buffers

[FallingSnow]

Is it possible to use buffers provided by the user to avoid a copy? Right now it seems that the buffers are allocated by library itself.

linux-video-rs/core/src/impls/buffer.rs

Line 187 in 51dc1b6

let mut buffer = Vec::<u8>::with_capacity(buffer.length as _);

@FallingSnow It's possible by using Linux Video API, but the transferring external buffers to kernel currently hasn't implemented yet.
In other words currently you can use userspace buffers which created by this crate not youself.

Ok I am +1 on this one. I am a refugee from v4l for this different reason but v4l can use DMA + user buffers like I do there

Any good & complete bindings do exist for video for linux at this stage?
