Issue:
|
||
|
|
One can't iterate over a source properties in Lua
|
||
|
|
|
||
|
|
Why it happens:
|
||
|
|
-- obs.obs_get_source_properties always returns nill
|
||
|
|
-- obs.obs_source_get_settings can't be iterated over
|
||
|
|
-- obs_properties_first can be used, but obs_properties_next expects a pointer while Lua bindings operate with objects
|
||
|
|
-- OBS devs ignored issues aimed to fix this for several years
|
||
|
|
|
||
|
|
Solution accepted by the OBS devs:
|
||
|
|
Use FFI to create a second wrapper for something that an already embedded LUa bindings should give access to.
|
||
|
|
|
||
|
|
My solution:
|
||
|
|
Use json-lua by tiye (https://github.com/tiye/json-lua/tree/main) to make JSON dataiteratable
|
||
|
|
|
||
|
|
How to use:
|
||
|
|
- add these lines to any of your scripts to be able to iterate over source properties through lua
|
||
|
|
- work with native Lua tables using 2 new methods
