Replay - Record your LedBorg, then play it back later

This is an old driver based LedBorg script
We recommend using the new driver free based scripts for LedBorg.
The new driver free examples can be found here, the installation can be found here.

We love to record things, music videos, and now LedBorgs!
It seemed a great idea to be able to record a sequence from one script and play it back by another.


So here we present Replay, our script for recording your LedBorg, and another to play it back later.
Replay comes in two parts:

• ReplayRecord.py
  This script records the actions of an attached LedBorg to a named file whilst running
• ReplayPlay.py
  This script plays back a named recording file at the rate it was recorded

There is only one variable you may wish to change, interval on line 9 of ReplayRecord.py defines the granularity of recording, smaller means a more accurate recording but a larger file is generated.

Here's the code, you can download the ReplayRecord script file as text here,
and you can download the ReplayPlay script file as text here.
Save the text files on your Raspberry Pi as ReplayRecord.py and ReplayPlay.py respectively.
Make the scripts executable using
chmod +x Replay*.py
record using
./ReplayRecord.py myvidname
and play using
./ReplayPlay.py myvidname
