It's a sad day when I realize that I did not add any null pointer
checking to any of the functions in this file. Discovered it while
checking all the different languages, happened when there was a missing
locale file for a certain module that hadn't had the language uploaded
yet.
These macros are used as easy helper functions to load/unload module
locale that's based upon the text_lookup system. You simple place the
OBS_MODULE_USE_DEFAULT_LOCALE macro once in the module, call
OBS_MODULE_FREE_DEFAULT LOCALE in obs_module_unload, and then
call obs_module_text anywhere in your module where you need to look up
text.
By default, it will look for a locale directory in your module's data
directory, and look for language files within it (INI locale format)
This function is used to simplify the process when using the default
locale handling for modules. It will automatically search in the plugin
data directory associated with the specific module specified, load the
default locale text (for example english if its default language is
english), and then it will load the set locale on top of the default
locale, which will cause text to use the default locale if the desired
locale text is not found.
Total bytes, total frames, and frames dropped. Total frames is
generated automatically, but total bytes and total dropped frames are
returned via callbacks.
Before it would assign the encoder/media callbacks directly to the
output's callbacks, so instead of doing that, it now goes through
intermediary functions for the sake of counting the frames.
Usually if you are reconnecting after network outage, it will give a
different code (such as OBS_OUTPUT_CONNECT_FAILED). So, if already
reconnecting, ignore the code unless it's OBS_OUTPUT_SUCCESS.
I was implementing a pushing/popping attributes function like with GL,
but I realized that for our particular purposes (and actually for most
purposes) its usage was somewhat.. niche. I may still implement
pushing/popping of attributes in the future, though right now I feel
using a function to reset the state is sufficient for our purposes.
There was no need to call the context free function in the
initialization function, and it's safer to just initialize the memory to
0 before using (which also negates the need for da_init)
This just ensures that if an obs object is renamed that the pointer to
older names will still be valid. Prevents renames from causing any
invalid memory access.
When the obs object is destroyed, so are the cached names.
The core itself now provides reconnection options (enabled by default, 2
second timeout between reconnects, 20 retries max until actual
disconnection occurs). This will make things easier for both module
developers and UI developers.
Reconnecting treats the stream as though it were still active, and
signals are sent when reconnecting and upon successful reconnection.
Need to implement user interface information for reconnections.
This implements the 'frame skipping' mechanism to forcibly cause frames
to be duplicated in order to reduce encoder complexity so the encoder
can catch up to the video, otherwise it will continue to be
progressively behind and will cause a desync of the video.
Typically, if a user gets this issue, they should turn down their
settings. For the love of god do not tell them that 'frames are
skipping', just tell them that CPU usage is high, and that they should
consider turning down their settings.
MagickCore is provided here as an alternative to FFmpeg in case FFmpeg
is not easily supported (for example, debian-based linux distros).
NOTE: Cmake configuration needs to be changed in order to allow
MagickCore image support.
NOTE: In texture_setimage, I had to move variables to the top of the
scope because microsoft's C compiler will give the legacy C90 error of:
'illegal use of this type as an expression'.
To sum it up, microsoft's C compiler is still utter garbage.
Similar to the shader functions, the effect parameter functions take
the effect as a parameter. However, the effect parameter is pretty
pointless, because the effect parameter.. parameter stores the effect
pointer interally.
...I'm actually concerned that I went a bit overkill trying to prevent
backwards compatibility issues with this abstraction design, because
this is a large number of files that have to be modified just to add a
single graphics subsystem export. Someone's going to strangle me, and
when you know that someone might strangle you, that means that you did
something wrong. We'll have to look in to simplifying this in the
future without killing backward compatibility safety.
The module callback obs_module_set_locale will be called after loading
the module, and any time the locale is manually changed via core API.
When this function is called, the module is expected to load new text
lookup values for all the text it uses based upon the current locale.
The locale parameter was a mistake, because it puts extra needless
burden upon the module developer to have to handle this variable for
each and every single callback function. The parameter is being removed
in favor of a single centralized module callback function that
specifically updates locale information for a module only when needed.
