Ubuntu creates zero byte audio mux files

[jasonsf]

foggycam2.log videos.txt

I'm compiling in windows using

dotnet build --runtime ubuntu.16.04-x64

Then moving the output to a docker container running on my NAS. It creates the video-only file correctly then creates a zero byte audio mux. Eventually crashed with a websocket io error. Attached is the log file (with ffmpeg logs too) and the directory listing of files created.

Thanks for the report, @jasonsf - I haven't tested this yet on Ubuntu. Will get to it shortly and see if there are any issues with the code where I am missing something.
