Struct WgpuFilterStats 

pub struct WgpuFilterStats {
    pub frames: u64,
    pub upload_secs: f64,
    pub gpu_secs: f64,
    pub download_secs: f64,
    pub hw_import_frames: u64,

}

Cumulative per-stage timings, readable while the filter runs via crate::wgpu_filter::WgpuFrameFilter::stats_handle.

Fields

frames: u64

Number of frames fully processed (readback completed).

upload_secs: f64

CPU time spent uploading planes/uniforms and encoding GPU passes.

gpu_secs: f64

Wall time the pipeline thread spent blocked waiting for GPU results. With frames_in_flight > 1, GPU work overlaps the next frame’s CPU work, so this is typically much smaller than the actual GPU time.

download_secs: f64

CPU time spent copying mapped readback bytes into output frames.

hw_import_frames: u64

Hardware input frames imported zero-copy (dmabuf).

hw_download_frames: u64

Hardware input frames downloaded to system memory instead — with hw_zero_copy_input enabled, a nonzero count reveals the import fallback engaging (a large per-frame perf cliff that a log line alone cannot make visible mid-stream).

hw_download_secs: f64

Wall time spent in av_hwframe_transfer_data downloads (previously folded into upload_secs, which hid the fallback’s cost).
