Flutter video_player 无法在一个页面中加载多个视频
Flutter video_player cannot load multiple videos in one page
我想在 Flutter 中创建一个包含多个循环视频的页面。在我的 phone（三星 Galaxy Note 10 Plus）上，所有视频都可以完美加载，但是当我 运行 在其他 phone 上使用相同的应用程序时（我试过三星 Galaxy S6 和 Galaxy A71) 正在加载 2 个视频，其他视频替换为 black squares。
这是我的 flutter doctor -v 运行:

我在应用程序的调试版本中没有收到任何错误，但视频仍然无法加载。
这是 video_player 控制器的配置：

clipVideo(this.path);

}
class _clipVideo extends State<clipVideo> {

//_controller = VideoPlayerController.network(

_initializeVideoPlayerFuture = _controller.initialize();
_controller.play();
_controller.setVolume(0.0);

super.initState();

@override

我把 video_player 版本换了一个新版本，但是没解决 anything.Is 可能是因为 phone 的问题？视频太大了吗？ （每个 record[number].mp4 有 8 - 10 MB）。
编辑：我尝试将视频的大小减小到 2-3 MB，但仍然不起作用。但是我发现当我进入那个有多个视频的页面时，video_player 插件 freezes/crashes（我在前一页上有另一个视频也冻结了），所以插件在某个地方崩溃了
第二次编辑：flutter runs 之后，我在这里找到了一些东西：
D/MediaCodecInfo(18771): AssumedSupport [sizeAndRate.rotated, 1080x2280x60.19792938232422] [OMX.Exynos.avc.dec, video/avc] [zeroflte, SM-G920F, samsung, 24]

而且我认为这是视频的问题，而不是播放器的问题
第三次编辑：裁剪和调整视频大小后，video_player 仅显示除最后一个视频之外的每个视频的第一帧。我不知道该怎么办
首先改变这个：
flutter:
assets:
- assets/images/
- assets/videos/
重新构建并 运行 应用程序。如果它不起作用，那么 运行 在终端上执行以下命令。
flutter upgrade
flutter config --android-studio-dir="C:\Program Files\Android\Android Studio"
flutter doctor -v
然后，如果问题仍然存在，则只需切换到 Beta 通道，升级 flutter 即可解决。
flutter channel stable
flutter upgrade
我问你 运行 终端命令，因为我注意到这个错误。
[!] Android Studio (version 4.1.0)
• Android Studio at C:\Program Files\Android\Android Studio
X Flutter plugin not installed; this adds Flutter specific functionality.
X Dart plugin not installed; this adds Dart specific functionality.
• Java version OpenJDK Runtime Environment (build 1.8.0_242-release-1644-b01)
让我知道它是否有效..
注意：在 运行 终端命令之后，您需要再次构建应用程序并且 运行。
我终于解决了。降级 video_player 插件并调整视频大小就可以了。
我想在 Flutter 中创建一个包含多个循环视频的页面。在我的 phone（三星 Galaxy Note 10 Plus）上，所有视频都可以完美加载，但是当我 运行 在其他 phone 上使用相同的应用程序时（我试过三星 Galaxy S6 和 Galaxy A71) 正在加载 2 个视频，其他视频替换为 black squares。

而且我认为这是视频的问题，而不是播放器的问题
第三次编辑：裁剪和调整视频大小后，video_player 仅显示除最后一个视频之外的每个视频的第一帧。我不知道该怎么办
首先改变这个：
flutter:
assets:
- assets/images/
- assets/videos/
重新构建并 运行 应用程序。如果它不起作用，那么 运行 在终端上执行以下命令。
flutter upgrade
flutter config --android-studio-dir="C:\Program Files\Android\Android Studio"
flutter doctor -v
然后，如果问题仍然存在，则只需切换到 Beta 通道，升级 flutter 即可解决。
flutter channel stable
flutter upgrade
我问你 运行 终端命令，因为我注意到这个错误。
[!] Android Studio (version 4.1.0)
• Android Studio at C:\Program Files\Android\Android Studio
X Flutter plugin not installed; this adds Flutter specific functionality.
X Dart plugin not installed; this adds Dart specific functionality.
• Java version OpenJDK Runtime Environment (build 1.8.0_242-release-1644-b01)
让我知道它是否有效..
注意：在 运行 终端命令之后，您需要再次构建应用程序并且 运行。
我终于解决了。降级 video_player 插件并调整视频大小就可以了。
