Get current frame/snapshot

Hi, I was wondering to know how could we get the current frame (by timespan)?
This peace of code will return an IInuptStream of a frame that we can use it.

        public static async Task<IInputStream> GetThumbnailAsync(StorageFile file,TimeSpan duration)
        {
            var mediaClip = await MediaClip.CreateFromFileAsync(file);
            var mediaComposition = new MediaComposition();
            mediaComposition.Clips.Add(mediaClip);
            return await mediaComposition.GetThumbnailAsync(
                duration, 0, 0, VideoFramePrecision.NearestFrame);
        }

but it's not working for HEVC/x265 codec.
Is there be a code or anything to get current frame in FfmpegInterop? or will be available in future?

[Ps: I'm not a c++ programmer]

The issue asks whether FFmpegInterop can retrieve a current video frame by timespan, especially for HEVC/x265, and references MediaComposition.GetThumbnailAsync. Start by reviewing FFmpegInterop's public media and frame-related APIs and codec handling; done should be a clearly scoped implementation or documented answer about supported frame extraction.
