[video_player] Playing Multiple videos

[codesniper9315]

Hello, support team!
Hope you are doing well.

I am using video_player package for my video sharing app (like tiktok). To play the video without delay time, I've converted mp4 to HLS(m3u8) and my app plays the HLS videos to users. But still have some delay time on playing each videos.
So I tried to load the next/prev videos when play current video. It looks like working fine for a moment. But the problem is that if I load more than 10 or more videos, videoPlayerController is not able to initialize the video anymore.

Expected results: can load multiple videos at the same time

Actual results: not able to keep 2 or more controllers at the same time

Code sample

==================== Initialize the videoPlayerController =================
class VideoService {
  static final Map<String, VideoPlayerController> _controllers = {};

  static Future<VideoPlayerController> initializeOnlineVideoPlayer(
    String url,
  ) async {
    if (_controllers.containsKey(url)) return _controllers[url]!;
    var a = Uri.parse(url);
    VideoFormat? videoFormat;
    if (a.pathSegments.last.endsWith('m3u8')) {
      videoFormat = VideoFormat.hls;
    } else if (a.pathSegments.last.endsWith('mp4')) {
      videoFormat = VideoFormat.other;
    } else if (a.pathSegments.last.endsWith('mkv')) {
      videoFormat = VideoFormat.dash;
    }
    VideoPlayerOptions options = VideoPlayerOptions(mixWithOthers: true);
    VideoPlayerController _controller;
    _controller = VideoPlayerController.network(
      url,
      formatHint: videoFormat,
      videoPlayerOptions: options,
    );
    _controller.setLooping(true);
    if (AppConfig.getMute) {
      _controller.setVolume(0);
    } else {
      _controller.setVolume(100);
    }
    try {
      await _controller.initialize();
      _controllers[url] = _controller;
    } catch (e) {
      debugPrint('Initialize online video player error: $e');
    }
    return _controller;
  }
}

====================== Request to load video ===========================
PageView.builder(
    key: const Key('timeline'),
    controller: _controller,
    scrollDirection: Axis.vertical,
    itemCount: provider.timelinePosts?.length,
    itemBuilder: (context, index) => VideoWidget(),
    onPageChanged: (index) {
      var isPostInitialized = VideoService.isPostInitialized(
        provider.timelinePosts![index],
      );
      if (!isPostInitialized) {
        _controller.jumpToPage(index - 1);
        return;
      }
      List<Future> futures = [];
      for (var i = 1; i <= 1; i++) {
        var prevIndex = index - i;
        var nextIndex = index + i;
        if (prevIndex > 0) {
          futures.add(VideoService.initializePostVideos(
            provider.timelinePosts![prevIndex],
          ));
        }
        if (nextIndex < provider.timelinePosts!.length - 1) {
          futures.add(VideoService.initializePostVideos(
            provider.timelinePosts![nextIndex],
          ));
        }
      }
      Future.wait(futures);
    },
  )
