Is it solved now? I have the same problem.

Is it solved now? I have the same problem.

I have been working on it but they have since released more versions so it works somewhat better. Here is the link https://github.com/androidx/media/blob/release/demos/compose/src/main/java/androidx/media3/demo/compose/MainActivity.kt
I have not utilize 1.6.1 yet but I will give it a try today. What I have experienced in 1.6.0 is that setting the Surface to TextureView produces more stable results than SurfaceView however I will see if that has changed in 1.6.1. If you can't get it to work I will help if I have time.

I'm glad to receive your reply. After some efforts, I have optimized it to a state that users can hardly notice it.

I am glad that you have found a solution. If i ever find something that works the best I'll update this for others.

I really hope there will be a perfect solution, rather than using tricks to make users unaware.

For others at the moment. In the link provided earlier https://github.com/androidx/media/blob/release/demos/compose/src/main/java/androidx/media3/demo/compose/MainActivity.kt on approx. line 124, changing the surfaceType to SURFACE_TYPE_TEXTURE_VIEW has help some with scrolling.

// Only use MediaPlayerScreen's modifier once for the top level Composable
    Box(modifier) {
        // Always leave PlayerSurface to be part of the Compose tree because it will be initialised in
        // the process. If this composable is guarded by some condition, it might never become visible
        // because the Player will not emit the relevant event, e.g. the first frame being ready.
        PlayerSurface(
            player = player,
//            surfaceType = SURFACE_TYPE_SURFACE_VIEW,
            surfaceType = SURFACE_TYPE_TEXTURE_VIEW,
            modifier = scaledModifier.noRippleClickable { showControls = !showControls },
        )

There is also a feature called PreloadManager that is being utilized to make other videos preloaded to prepare before being loaded.

[Yyilin001]

The problem comes from calling the prepare function

[lostdawg3]

What’s the issue with it. Is it finding how to call it?

[Yyilin001]

Whenever this function is called, the main thread will be blocked. Especially when calling this function while scrolling the list, you will see obvious interface jumps.

Do you have a set of code I could see on how you are implementing it.
