Notes:
This plugin part can load libltc, a library to encode and decode linear timecode.
Linear (or Longitudinal) Timecode (LTC) is an encoding of timecode data as a Manchester-Biphase encoded audio signal.
The audio signal is commonly recorded on a VTR track or other storage media.
libltc facilitates decoding and encoding of LTC from/to timecode, including SMPTE date support.

Encoder and LTCframe flags
| Constant | Value | Description |
|---|---|---|
| LTC_BGF_DONT_TOUCH | 4 |
Encoder init or re-init does not touch the BGF bits (initial values after initialization is zero) |
| LTC_NO_PARITY | 8 |
Parity bit is left untouched when setting or in/decrementing the encoder frame-number |
| LTC_TC_CLOCK | 2 |
The Timecode is wall-clock aka freerun. This also sets BGF1 (unless LTC_BGF_DONT_TOUCH is given) |
| LTC_USE_DATE | 1 |
LTCFrame <> SMPTETimecode converter and LTCFrame increment/decrement use date, also set BGF2 to '1' when encoder is initialized or re-initialized (unless LTC_BGF_DONT_TOUCH is given) |
TV Standards
| Constant | Value | Description |
|---|---|---|
| LTC_TV_1125_60 | 2 |
30fps |
| LTC_TV_525_60 | 0 |
30fps |
| LTC_TV_625_50 | 1 |
25fps |
| LTC_TV_FILM_24 | 3 |
24fps |
