我在 nextjs 应用程序中使用 Fluent-ffmpeg，我正在尝试处理视频并指定在我的 s3 存储桶上进行流式传输的格式，但它一直失败。我的终端不断抛出“错误：错误：输出格式 mp4 不可用”。我已经验证了我的 ffmpeg 格式“ffmpeg -format”并确认它支持编码和解码 mp4 文件。我已经尝试过其他论坛的解决方案，但它对我不起作用。

我应该能够将处理后的视频流式传输到我的 s3，但它不断抛出“错误：错误：输出格式 mp4 不可用”
对于那些在 Fluent-ffmpeg 中遇到此问题的人，请检查您的 ffmpeg 版本，新版本 7.0.0 对其格式进行了一些更改，从而导致了一些错误。您可以阅读此link中的讨论。只需将您的 ffmpeg 降级到较低版本即可。
