我正在尝试使用此处描述的 Google Transcoder API 裁剪视频：https ://cloud.google.com/transcoder/docs/how-to/crop-videos

转码成功运行，但没有发生裁剪，并且转码作业详细信息实际上缺少裁剪请求。

我正在使用 npm @google-cloud/video-transcoder 1.5.0 版

这是 json 请求：

有人在使用 Google Cloud Transcoder API 裁剪视频方面有运气吗？

我安装了 NodeJS 模块并尝试使用相同的配置运行作业，并且可以确认这可以重现。

问题可能是客户端库的 v1beta1 原型自最初创建以来尚未同步。

我们已经创建了一个修复并部署到 prod。它现在应该可以工作了。
