Reproduction steps
Using androidx.tv version 1.0.0-alpha06 with the following composable (adding focusable and focusRequester were my attempts to fix it):
@OptIn(ExperimentalComposeUiApi::class)
@Composable
fun VideoPlayer(mediaItem: VideoApi.MediaItem) {
    val (playerFocus) = remember { FocusRequester.createRefs() }
    val context = LocalContext.current
    val exoPlayer = remember {
        ExoPlayer.Builder(context)
            .build()
            .apply {
                addMediaItem(
                    MediaItem.Builder()
                        .setUri(mediaItem.hlsCaptions)
                        .setMimeType(MimeTypes.APPLICATION_M3U8)
                        .build()
                )
                prepare()
                playWhenReady = true
            }
    }
    LaunchedEffect(Unit) {
        playerFocus.requestFocus()
    }
    DisposableEffect(
        AndroidView(
            modifier = Modifier
                .focusable(true)
                .focusRequester(playerFocus),
            factory = {
                StyledPlayerView(context).apply {
                    player = exoPlayer
                    useController = true
                    controllerAutoShow = true
                    setShowBuffering(StyledPlayerView.SHOW_BUFFERING_ALWAYS)
                }
            }
        )
    ) {
        onDispose {
            exoPlayer.release()
        }
    }
}
Expected result
Should be able to interact, i.e. D-pad should bring up video HUD controls.
Actual result
Any key presses (besides back) do nothing.
Media
Any media should show it. I’m using an HLS stream. For example: https://m.wsj.net/video/20230531/eaa54145-d07a-4100-8153-2eaf8d671921/1/hls/manifest-hd-wifi.m3u8

@taschmidt Stream them in a Flow. Inject the flow into the Activity and also in the ViewModel/whatever constructor.
DPAD means you only have a limited set of inputs “events”, which makes it hacky, but “reasonable” (I claim) to pass them down from the Activity if Compose cannot receive them (eg: system keys that come into the app via an Intent instead of a KeyEvent).
