Video_player 崩溃 Android Flutter 中的模拟器
Video_player Crashes Android Emulator in Flutter
我正在尝试使用 video_player，但出现以下错误。我还添加了一个 MRE（最小可重现示例）。
我在 Android Studio Beta 中使用了模拟 Pixel 4、模拟 Pixel 4 XL 和模拟 Pixel 5，但其中 none 有效。
以下错误是我使用 Pixel 4 XL 时出现的，但所有这些错误都一样。
错误：

确实，这可能是那个 Flutter 包的错误。您是否尝试在该软件包的 GitHub 中创建问题？
其次，在我的开发过程中，我看到好几次模拟器都失败了，而真实设备总是能正常工作。我使用的解决方案是 - 只是 而不是 在模拟器上测试它们。真正的用户从不使用模拟器，不是吗？
在 x86 arch（arch 模拟器使用）上 运行 时可能是库的错误。那么，任何拥有真实设备（arm arch）的人都不会看到这个错误。
第三，尝试使用“云真实设备”来测试它们是否可以在您担心的真实 Pixel 设备上运行如何。有许多平台托管一些真实设备，您可以通过网页连接到它们并测试您的应用程序。
此错误与抖动无关，而与 exoplayer 本身内部的媒体支持有关。
I/VideoCapabilities( 5318): Unsupported profile 4 for video/mp4v-es
这表明从服务器流式传输的视频是mp4v-es。这表明格式与平台不兼容 android.
这已经在 Github 上向 google exo-player 报告了。
https://issueexplorer.com/issue/google/ExoPlayer/9388
这似乎是直播 URL，您需要从服务器端将它们转换为 android 和 IOS 视频播放器支持的格式，或者您可以在平台端解决这个问题。
我也遇到了这个问题，在我的模拟设备上播放任何视频（不仅仅是在 Flutter 应用程序中）都会崩溃并终止模拟器的进程。
为防止出现此问题，我执行了以下操作：
- 关闭您的模拟器设备。
- 转到 Android Studio 中的设备管理器。
- 单击模拟器设备上的编辑按钮。
- 在虚拟设备配置对话框中单击显示高级设置。
- 在仿真性能部分，将图形设置为软件-GLES 2.0，而不是默认 Automatic.
- 启动您的模拟器设备。
有一点需要注意，由于将图形切换到软件，模拟器设备上的性能很慢，如果您 运行 使用的系统功能强大，那么您不会注意到这种性能下降。
我正在尝试使用 video_player，但出现以下错误。我还添加了一个 MRE（最小可重现示例）。
我在 Android Studio Beta 中使用了模拟 Pixel 4、模拟 Pixel 4 XL 和模拟 Pixel 5，但其中 none 有效。
以下错误是我使用 Pixel 4 XL 时出现的，但所有这些错误都一样。

确实，这可能是那个 Flutter 包的错误。您是否尝试在该软件包的 GitHub 中创建问题？
其次，在我的开发过程中，我看到好几次模拟器都失败了，而真实设备总是能正常工作。我使用的解决方案是 - 只是 而不是 在模拟器上测试它们。真正的用户从不使用模拟器，不是吗？
在 x86 arch（arch 模拟器使用）上 运行 时可能是库的错误。那么，任何拥有真实设备（arm arch）的人都不会看到这个错误。
第三，尝试使用“云真实设备”来测试它们是否可以在您担心的真实 Pixel 设备上运行如何。有许多平台托管一些真实设备，您可以通过网页连接到它们并测试您的应用程序。
此错误与抖动无关，而与 exoplayer 本身内部的媒体支持有关。
I/VideoCapabilities( 5318): Unsupported profile 4 for video/mp4v-es
这表明从服务器流式传输的视频是mp4v-es。这表明格式与平台不兼容 android.
这已经在 Github 上向 google exo-player 报告了。 https://issueexplorer.com/issue/google/ExoPlayer/9388
这似乎是直播 URL，您需要从服务器端将它们转换为 android 和 IOS 视频播放器支持的格式，或者您可以在平台端解决这个问题。
我也遇到了这个问题，在我的模拟设备上播放任何视频（不仅仅是在 Flutter 应用程序中）都会崩溃并终止模拟器的进程。
为防止出现此问题，我执行了以下操作：
- 关闭您的模拟器设备。
- 转到 Android Studio 中的设备管理器。
- 单击模拟器设备上的编辑按钮。
- 在虚拟设备配置对话框中单击显示高级设置。
- 在仿真性能部分，将图形设置为软件-GLES 2.0，而不是默认 Automatic.
- 启动您的模拟器设备。
有一点需要注意，由于将图形切换到软件，模拟器设备上的性能很慢，如果您 运行 使用的系统功能强大，那么您不会注意到这种性能下降。
