Arch Linux (from git), cannot start stream

[johnhamelink]

Hey there,

I'm trying to get Tachyon streaming on Linux. I used the PKGBUILDs in this comment (although I had to slightly modify them to make them work): #52 (comment)

Tachyon runs, but when you try to initiate the steam, the following message is displayed: "An unspecified error occurred while recording."

Here are the logs:
