Loading thumbnails for videos in device gallery about accompanist HOT 4 CLOSED

Ah, turns out that Coil has support for this: https://coil-kt.github.io/coil/videos/

I haven't tried this, but it should then work as:

CoilImage(
    data = videoUri,
    requestBuilder = {
        videoFrameMillis(1000)
    },
    contentScale = ContentScale.Crop,
)

Thank you, this perfectly solves my problem. I only had to write my own VideoFrameUriFetcher to always return true in handles as the uri's last path segment does not indicate that it is a video (uri.toString() looks rather like this: 'content://media/external/video/media/15383').

Hmmm, do you're not really using Coil here at all, as you're just displaying a Bitmap. You could replace CoilImage with Image and it would work the same.

You should look at our Asynchronous operations in Compose doc to get an idea of how to do this (specifically the bit about LaunchedEffect)

Hi Chris, thank you for your rapid reply. Indeed, I was thinking about using Image directly. Because I have a very large grid displaying thumbnails of all videos of the device, I thought using the build in caching and asynchronous loading of CoilImage instead of writing it myself. Also, because CoilImage can be used to display the images of the device, I thought I can use it to display video thumbnails.

I'll take a look at your links and think about how implementing it using Image.

Edit: I know the solution above fetches the bitmap directly and passes it to CoilImage. That was only a first attempt, and I looked for a way to delegate the call to Uri.thumbnailFromVideoAt to some suspend function of CoilImage.
