DirectShow 编辑服务可以在多台机器上并行运行吗?
是否可以以任何方式在多台机器上并行处理至少 1 个 DShow 视频项目相同的时间是为了更快的渲染还是只是为了好玩?
任何语言?在任何程序的帮助下?
Is it in any way possible to process at least 1 DShow video project on multiple machines in parallel at the same time for faster rendering or just for fun?
In any language? With help of any program?

简短的答案是肯定的,但这不是一个非常实用的解决方案
假设您确实设法创建了一个系统,该系统可以跨机器分解视频以进行分布式解码。首先,您必须小心如何“分解”视频。您必须始终从关键帧开始并在下一个关键帧之前结束。接下来您必须解码您的剪辑。解码后,解码后的数据必须传输到渲染视频的计算机。未压缩的 1080p @ 30 FPS 流约为 182 兆字节/秒,这超出了千兆位连接的处理能力。
最好通过多个核心和 GPU 进行解码。
The short answer is yes, but it's not a very practical solution
Lets say you did manage to create a system that broke a video up across machines for distributed decoding. You first would have to be careful on how you did "break up" the video. You must always start at keyframe and ending right before the next keyframe. Next you would have to decode your clip. Once decoded, the decoded data must be transfered to the computer rendering the video. An uncompressed 1080p @ 30 FPS stream would be ~182 megaBYTES/s, which is more than a gigabit connection can handle.
You are better off decoding over multiple cores and the GPU.
