I'm using a Raspberry Pi 2 with an image from this thread. Here's my configuration file. I'm using WS2812B-type LEDs. The problem is that it works fine grabbing frames from an HDMI input for ~4 minutes, but then suddenly all the LEDs stop responding to the image and turn off except the left side. The Raspberry Pi is connected to the data pin on the strip at the bottom of the left side. Any ideas on what could be happening?
