Re: libav-tools depends on X11!?

I'm also streaming over the network but not with the performance I expected. I installed the precompiled libav-tools before discovering it includes software-only encoding. I wasn't concerned about the cruft. In searching for tips to compile libav with hardware encoding, I found your post and thought...

Re: VCHIQ Error on Rasberry Pi 2

I have essentially the same problem except for the returned error code. I updated the firmware but that didn't fix the problem. Is that all you had to do to fix yours?

Re: "Wifi Config" icon disappeared

Before using this solution, I saw on the boot screen a message that said "Not running dhcpcd because /etc/network/interfaces defines some interfaces that will use a DHCP client". After commenting two lines in /etc/network/interfaces that contained "d...

Where is the tutorial? I've been looking for something official but have only found anecdotal tips.

Re: Low latency wifi stream possible?

MrBunsy, did you use the commands from the blog instructions on the RPi side? Not quite - I set the server (pi) side up so it was listening...and stuck that in a while loop with bash. I prefer your idea of having the RPi listen so I used a similar command in a while loop but how do you keep it from...
