Method read_decoded

rustcv-camera/src/camera.rs:133–137

Capture and decode the next frame into a reusable [`Mat`]. 采集并解码下一帧到可复用的 [`Mat`]。 This combines `next_frame()` + decode in a single call. The `Mat` is reused across calls to avoid per-frame allocation. 将 `next_frame()` + 解码合并为单次调用。 `Mat` 跨调用复用以避免每帧分配。

    /// 将 `next_frame()` + 解码合并为单次调用。
    /// `Mat` 跨调用复用以避免每帧分配。
    pub fn read_decoded(&mut self, mat: &mut Mat) -> Result<bool> {
        let frame = self.next_frame()?;
        crate::decode::decode_frame(&frame, mat, None)?;
        Ok(true)
    }
