as far as I know the only chipset supported by a raspberry pi SPI is ws2801
All the others have clock constrains too strict to work

Meby you can use this: https://www.adafruit.com/product/1689
Works good with WS2801 & WS2811 i am not sure if its wil work wiht the WS2813
You can select the output in ola (then its possible to controll them with qlc)

You can get a nice python/C package from gitHub. rpi_ws281x I have tested it with both WS2812 and WS2813 strips. Here is the link: https://github.com/jgarff/rpi_ws281x

If the ws8213 is compatoble with 8212/8211, I have a solution for this:

I built a 300px LED matrix last week and put together a python script that recieves data over ArtNet thus controlling the matrix.

I posted instructions in my blog: https://keawe.de/en/led-matrix
