When using Coil to load videos from URIs generated with

ContentResolver

, I need to explicitly pass the fetcher to the request builder, otherwise Coil cannot process the video (since the URI does not contain the file type). E.g.:

Image(
    painter = rememberImagePainter(
        data = contentUri,
        builder = {
            fetcher(VideoFrameUriFetcher(LocalContext.current))
        },
    ),
    contentDescription = null,
)

Creating the

VideoFrameUriFetcher

instance for every video seems kind of inefficient. Is there a better Compose way?

Why not hoist the video frame fetcher?

Yeah, probably makes sense. Thanks.

The frame fetcher could live inside your viewmodel too so it won't be recreated on every recomposition, although I am not sure if

builder

already does some caching for you
