Better handling for orphan ffmpeg processes?

[tjdans1114]

Hello. Thanks for the wonderful package in advance.

I have problems with orphan ffmpeg processes (similar to https://github.com/k-yle/rtsp-relay/issues/196) which consume quite amount of hardware resouces. So...

Are there plans to handle this problem? Possible solutions I think are

1. remove the cause of non-killing of the process (which I am not aware of)
2. provide another kill-method other than killAll (as killAll basically also kills active processes)
3. or provide ways to manipulate Inbound directly
