Read a timecode source to write fiddle factor?

[mixographer]

Again, not an issue, but it would be a neat feature if we could write the fiddle factor from a timecode source. It's probably a whole new project, but it would be a great feature. For instance, flip a switch and read timecode from a different source, and then write a fiddle.txt that uses that correction to send out the modified timecode.

Maybe it's too hard to read the timecode and then sync to what the NTP time is?

EDIT: To clarify, my interest here would be to jam in some timecode, and then use the NTP + an adjustment to keep running the clock at the new timecode, even if it is not the real time, according to NTP.

Could see that being useful. You would not happen to know of a small/ESP32 suitable SMPTE decoding library by any chance ?
