I am new to the Raspberry Pi so I apologize in advance if I am missing something totally obvious.
I am trying to play video on my LED WS2812 array. Currently, the array has 89 pixels per strip and 64 strips. In the past, I have used an old laptop to run this display using Paul Stoffregen’s Movie2Serial script.
That laptop was so old that I decided to try it on a Raspberry Pi and got a smaller array working with this version of Paul’s script:
[https://forum.processing.org/two/discussion/26295/movie2serial-video-format-problem-i-think](https://forum.processing.org/two/discussion/26295/movie2serial-video-format-problem-i-think)
My problem is that I can get my array to work if the script thinks there are only 48 rows, but as soon as I increase to 56 (or 64), it freezes up before it can display anything on the array. 48 rows is 4,272 LEDs, am I hitting some type of limit on the capabilities of the Pi?
Here is the console error I sometimes get when it freezes:

Is anybody out there? Has anyone else tried this?
