Struct PreviewMediaRequest 

pub struct PreviewMediaRequest {
    pub items: Vec<PreviewMediaItem>,
    pub start_index: i32,
    pub advance: PreviewMediaAdvance,
    pub show_index_indicator: bool,
    pub callback_id: u64,
    pub presented_callback_id: u64,
}

Fields

items: Vec<PreviewMediaItem>

start_index: i32

advance: PreviewMediaAdvance

show_index_indicator: bool

callback_id: u64

Callback_id for the final preview result. Fires once when the session ends (manual/auto/interrupted/error). Payload: serialized PreviewMediaResultObj ({reason, lastIndex}).

presented_callback_id: u64

Callback_id for the “first frame composited” signal. Fires once when the first pixel of the underlying media has been painted to screen. Native MAY skip on degenerate paths (abort before any item rendered, process tear-down, etc.) — the JS-side presented Promise is also woken by a fallback when completed settles, and by a total timeout after that, so it never hangs. The callback payload, when fired, is an empty JSON object {}.
