I'm currently creating a windows app with Tauri and Svelte, but ran into some problem. I have a button which when clicked opens the file system to allow a new video to be selected. When a new video is selected I update the VideoStore with the new path. This all works great, and with the below code the video then updates to show the new video, however I also want to reset time = 0 so that the new video starts from the beginning, but that isn't happening here. So if the previous video was at 20 seconds when a new file is being selected, the new video also starts at 20 seconds.

When clicking the Reset button the time changes back to 0, but I would like it to also happen automatically when VideoStore gets updated and the new video is loaded.

I update the time when $VideoStore changes and time is bound to the video's currentTime:

    $: {
        time = 0;
        video_src = `https://asset.localhost/${$VideoStore}`;
    }

The full code:

Video.svelte

<script>
    import VideoStore from "../stores/VideoStore";

    let video_src = $VideoStore;

    let time = 0;
    let duration;
    let paused = true;

    const skip = () => {
        time += 10;
    };

    function resetTime() {
        time = 0;
    }

    $: {
        time = 0;
        video_src = `https://asset.localhost/${$VideoStore}`;
    }
</script>

<p>{time}</p>
<button on:click={resetTime}>Reset</button>
<button on:click={skip}>Skip 10 seconds</button>
<!-- svelte-ignore a11y-media-has-caption -->
<div class="player">
    {#key video_src}
        <video
            src={video_src}
            width="1280"
            height="720"
            bind:currentTime={time}
            bind:duration
            bind:paused
            controls
        >
        </video>
    {/key}
</div>

OpenButton.svelte

<script>
    import { open } from "@tauri-apps/api/dialog";
    import { documentDir } from "@tauri-apps/api/path";

    import VideoStore from "../stores/VideoStore";

    let filename = "";

    const openfile = async () => {
        const selected = await open({
            directory: false,
            multiple: false,
            defaultPath: await documentDir(),
        });

        filename = selected.replace(/\\/g, "/");
        VideoStore.update(() => {
            return filename;
        });
    };
</script>

<button on:click={openfile}>Open File</button>
