我在node.js服务器上使用bitmovin-javascript。我正在尝试为Firebase存储上的视频创建编码，并使用bitmovin-javascript API将输出保存到我的bitmovin帐户中。
我已经从旧的bitmovin api（v1）升级为javascript（现已弃用），并且正在实现当前的api（v2）。但是每次我运行该代码时，它都显示HTTP请求失败：在我的终端控制台中，HTTP响应代码被禁止为403。
我已经进行了交叉检查，并确保我正在从Firebase存储中读取的API密钥（accesss-key和secret-key）是有效密钥，并且bitmovin API密钥也是有效密钥。 bitmovin的输出ID也是有效的ID。
该api生成输入和视频编解码器配置，音频编解码器配置和清单，但不生成输出或编码。
该错误似乎是在api试图创建编码资源的时候发生的。
这是我的代码的样子：
const Bitmovin = require('bitmovin-javascript').default;
const start = async () => {
const bitmovin = Bitmovin({ 'apiKey': 'xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx' });
// create the input

// create the output
const outputId = "XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX";
// create the video and audio codec configurations

我希望该API能够读取我的Firebase存储，对来自该存储的视频进行编码，将其存储在我的bitmovin输出下，为我提供一个到输出的bitmovin链接，以便可以将其保存到我自己的数据库中。
帮助将不胜感激。
最佳答案
到目前为止，我还没有注意到您提供的代码段有任何特定的问题。但是，此问题可能是由另一个因素引起的，例如输入/输出设置或输入文件本身。
请随时与[email protected]取得联系并提供编码ID和输入文件，以便我们对此进行更详细的研究。
