When creating a source, it was possible to create duplicates. That has
now been fixed. I think that perhaps libobs shouldn't even allow for
duplicates in its core code, just to be safe. Will have to consider
doing that in the future.
This patch adds support for multi-screen setups by using xinerama
information if available to determine the screen size and position.
In case xinerama is not available or not active it uses the information
provided for the x screen.
To clean up the code some generic helper functions were moved to a
separate source file.
Add a 'source selection' dialog to replace the 'enter a name' dialog.
This new dialog allows you to make new instances of pre-existing sources
so that you can add a pre-existing source to a different scene, or in to
the same scene more than once.
Also started implementing locale.
Comtemplating switching to JSON-based locale later, so we can add things
like descriptions/disambiguation, and so we can use jansson's built-in
hash table when doing the string lookup.
First, if the private data of the source fails to be created, then do
not destroy the source. If the source is destroyed, all the user's data
associated with that source is lost, which could end up being a
potential problem. Instead, let it linger as a 'dead' source until the
user chooses to fix the problem (though this should never really happen,
the source module functions should be programmed to handle this
scenario)
Secondly, rename new_frame_ready to ready_async_frame, and fix a
potential memory leak with it.
obs_source_output_video can cause cached frames to be freed twice if
called with a partially destroyed source, among other undesirable
effects; freeing the source private data right after the destroy signal
has been processed ensures proper behavior
- Add volume control
These volume controls are basically nothing more than sliders. They
look terrible and hopefully will be as temporary as they are
terrible.
- Allow saving of specific non-user sources via obs_load_source and
obs_save_source functions.
- Save data of desktop/mic audio sources (sync data, volume data, etc),
and load the data on startup.
- Make it so that a scene is created by default if first time using the
application. On certain operating systems where supported, a default
capture will be created. Desktop capture on mac, particularly. Not
sure what to do about windows because monitor capture on windows 7 is
completely terrible and is bad to start users off with.
I had forgotten how constants worked when compiled; constants are
uploaded as constant registers. When constants are used with shaders,
multiple constants are often packed in to a single register when
possible to reduce constant register count.
For example, one 'float' constant and one 'float3' constant will be
packed in to a single register (c0.x for constant 1, c0.yzw for constant
2), but two 'float' constants and one 'float3' constant must inhabit two
registers (c0.xy for constant 1, c1.xyz for constant 2), so it must
start on a new register boundry (every 16 bytes).
I had first instinctively thought it was just a simple case of
alignment like it is on the CPU, but then I realized that it didn't
sound right, so I went back and did some more tests and then ultimately
remembered how constants actually are uploaded.
