Implementations

impl EditorPreviewState

pub fn open(&self, project: EditProject) -> Result<(), String>

Open or update the preview for project.

Re-opens the decode stream + compose pipeline only when the source clip or the output canvas changed (a new clip, or an aspect-ratio change that reshapes the canvas — AUT-513); otherwise it just swaps the stored project — re-applying the background only when it changed — so edits (zoom / speed / crop / cursor) take effect on the next composed frame without rebuilding wgpu on every keystroke.

Errors

Returns a message if the source can’t be opened or the wgpu compose pipeline can’t be created.

pub fn frame_bytes(&self, frame: u64) -> Vec<u8>

Compose the stored project’s frame frame to BGRA bytes, or an empty Vec when there is no open session or the frame is past the end (the webview skips an empty buffer, exactly like the camera preview poll).
