Notes that it does nothing if the combination of `signal`,
`callback`, and `data` is already connected to the handler.
Adds missing param `signal` description.
Typo fix
Adds links to release functions for "new/incremented reference".
Extra info on signal handler.
Parameter description on `obs_property_list_add_*` functions, since
their parameter `name` can be confusing and it is unclear which value
is stored in obs_data_t.
Adds clarifications on calldata_ptr.
8dda8d3500 added a few functions to get the last
recording/replay/screenshot path, but it should return allocations
because it's possible for the data to be modified at a later point.
Authors can use :wiki:`PageName` and :source:`libobs/obs.h` to link to
files/pages rather than providing full links. If custom test is needed,
wrap the path in additional <>.
Example: :wiki:`Use the Wiki <Install-Instructions>`
obs_find_modules2 allows the ability to get the module name in the
callback, and the change to obs_find_modules2 also adds the ability to
find out whether any modules failed to load or not.
The function `os_sleepto_ns` has a spin loop so it will consume CPU
resource. The new function has same interface but consumes less CPU
resource with a drawback of less precision.
Allows a frontend the ability to set the maximum audio buffering
latency, and specify whether that audio buffering is either fixed (to
the maximum audio buffering latency), or dynamically increasing from 0.
This will be useful if the user wishes to output audio to devices or
through a virtual audio device at a guaranteed minimal latency.
HLG output uses MovieLabs-recommended procedure.
- If peak luminance is greater than 1000, use maxRGB EETF to 1000.
- Otherwise, don't tonemap.
- Then use normal HLG conversion procedure with gamma 1.2 (1000 nits).
Rec. 2020 is really an SDR spec, but I think HDR10 made it okay to slap
PQ on it, call it an HDR spec. Rec. 2100 came along after and formally
allowed the use of PQ/HLG, so we should use 2100 instead.
The fade transition could benefit by providing NULL to differentiate a
real source texture from the transparent placeholder. This would give it
a chance to fade correctly for source transitions.
