Hi,
Kind of late, but here is another comment. EMS, on input side, doesn’t do any buffering at all. As Bryan explained, buffering happens when/where is required. There is no such thing as an "input buffer" because it makes no sense :)” />
The data is already in the brains of EMS so it needs to be put on files or pipes (players). That is when buffering may be-needed/occur. So the buffering always (if) happens on outputs, not inputs. Files will not buffer at all, because they are local and they can be written very fast. of course, the speed of the HDD matters here. but even on a HDD (non SSD) you have around 50MB/s write speed (worst case scenario). That is plenty of bitrate for small or few streams. Larger deployments, obviously, require more advanced pieces of hardware like SSD or more memory (cached mem drives)
Best regards,
Andrei
