If the audio subsystem was buffered to any extent, the audio of a raw
output would start off at a negative offset, requiring each raw output
to implement a "prepare_audio" function (as seen in the FFmpeg output)
in order to ensure proper synchronization with video. This did not
apply to encoded outputs because it was already being performed by the
obs-encoder code.
Fix ternary test to use BGRX render targets for YUV to RGB
conversions. The previous behavior may have been fine though since
the shaders fill the alpha channel with 1.0 anyway.
Code submissions have continually suffered from formatting
inconsistencies that constantly have to be addressed. Using
clang-format simplifies this by making code formatting more consistent,
and allows automation of the code formatting so that maintainers can
focus more on the code itself instead of code formatting.
The cache coherency of rasterization for full-screen passes is better
using an oversized triangle that is clipped rather than two triangles.
Traversal order of rasterization is GPU-specific, but will almost
certainly be better using an undivided primitive.
A smaller benefit is that quads along the diagonal are not evaluated
multiple times, but that's minor in comparison.
Redo format shaders to bypass vertex buffer, and input layout. Add
global shader bool "obs_glsl_compile" to make API-specific decisions,
i.e. handle upside-down UVs. gl_ortho is not needed for format
conversion because the vertex shader does not use ViewProj anymore.
This can be applied to more situations, but start small first.
Testbed full screen passes, Intel HD Graphics 530:
RGBA -> UYVX: 467 -> 439 us, ~6% savings
UYVX -> uv: 295 -> 239 us, ~19% savings
Similar to item_visible, this event fires whenever a scene item is
locked or unlocked. This allows the UI and libobs to remain in sync
regarding scene elements' statuses.
Fixes a bug where if the user gave a custom color to a source list item,
the edit box used with renaming the item would also have that
background color while editing the name, awkwardly.
If the user gave the source list item a custom color, the "background"
stylesheet value would apply to children of the item widget, causing the
lock/eye checkboxes to also have that background color added on top of
the chosen color. This is fixed by explicitly settings the background
value to none on the lock/eye checkboxes.
Apparently certain versions of Qt have a bug where the tray icon's
internal "visible" variable is set to false despite the fact that it
still shows. Calling show() first before calling hide() sets the
internal boolean value and fixes the issue with the hide call.
