VideoThumbnailImageData
Image request data for a video preview that should be loaded from the server thumbnail when available, and fall back to a frame extracted from the video itself when the thumbnail is missing or fails to load.
Pass an instance of this as the Coil request data (instead of a raw URL) to opt into the fallback handled by VideoThumbnailFallbackInterceptor.
Parameters
thumbnailUrl
The server-provided thumbnail URL, already transformed for CDN resizing if enabled.
videoUrl
The URL of the video asset, used to extract a preview frame when thumbnailUrl fails.
