/** * After successfully configuring the component, call {@code start}. * <p> * Call {@code start} also if the codec is configured in asynchronous mode, * and it has just been flushed, to resume requesting input buffers. * @throws IllegalStateException if not in the Configured state * or just after {@link #flush} for a codec that is configured * in asynchronous mode. * @throws MediaCodec.CodecException upon codec error.

这是 MediaCodec 类中的一个注释，说明了该类中的 start() 函数的作用。该函数的作用是启动媒体编解码器实例，以开始对媒体数据进行编解码操作。在成功配置媒体编解码器实例之后，需要调用该函数才能开始编解码操作。

该注释还指出，如果媒体编解码器实例是在异步模式下配置的，并且刚刚刷新过，请调用 start() 函数以恢复请求输入缓冲区。如果媒体编解码器实例处于 Configured 状态之外的其他状态，或者在异步模式下配置的编解码器刚刚刷新过，则会抛出 IllegalStateException 异常。如果在调用 start() 函数时发生编解码器错误，则会抛出 MediaCodec.CodecException 异常。

这段代码看起来是一个方法的注释，它描述了一个分布式系统中的锁的获取方法。该方法会在尝试一定时间后，如果没有获取到锁，就返回 false；如果获取到了锁，锁会一直保持到 unlock 方法被调用，或者到指定的时间 leaseTime 到期。在这个过程中，如果线程被中断，该方法会抛出 InterruptedException 异常。

The VS Code Server failed to start.

The VS Code Server failed to start usually occurs when there is an issue with the server-side component of Visual Studio Code. This can happen due to various reasons, such as incompatible extensions, corrupted installation, or insufficient system resources.

To troubleshoot this issue, you can try the following steps:

1. Restart Visual Studio Code: Sometimes, a simple restart can resolve the issue. Close all instances of VS Code and open it again.

2. Disable extensions: In some cases, incompatible or faulty extensions can cause the server to fail. Try disabling all extensions and see if the server starts successfully. If it does, you can enable the extensions one by one to identify the problematic one.

3. Update Visual Studio Code: Make sure you are using the latest version of VS Code. Updates often include bug fixes and improvements that can resolve such issues.

4. Check system requirements: Ensure that your system meets the minimum requirements for running Visual Studio Code. Insufficient system resources can cause the server to fail.

5. Reinstall Visual Studio Code: If none of the above steps work, you can try reinstalling VS Code. Uninstall it completely from your system and then download and install the latest version from the official website.

If the issue persists after trying these steps, you may need to seek further assistance from the VS Code community or support channels.
