Certain types of sources (display captures, game captures, audio
device captures, video device captures) should not be duplicated. This
capability flag hints that the source prefers references over full
duplication.
Darkest dungeon uses an unusual technique for drawing its frames: a
fixed 1920x1080 frame buffer used in place of the backbuffer, which is
then stretched to fit the size of the screen (whether the screen is
bigger or smaller than the actual texture).
The custom frame would cause glReadBuffer to initially fail with an
error. When this happens, their custom frame buffer is in use, so all
that needs to be done is simply reset the capture and force the current
output size to 1920x1080 while that custom frame is in use.
They presumably did this in order to ensure the game looks the same at
any resolution. Instead of having to use power-of-two sprites and
mipmaps for every single game sprite and stretch/skew each of them
(which would risk the final output "not looking quite right" at
different resolutions), they simply use non-pow-2 sprites with no
mipmaps and render them all on to one texture of a fixed size and then
stretch that final output texture. That ensures that the actual
composite of the game still looks the same at any resolution, while
reducing texture memory by not requiring each sprite to use a
power-of-two texture and mipmaps.
Adds the option of making the media file restart when the source becomes
active (such as switching to a scene with it).
Due to lack of libff features to start/stop/pause/seek media files,
currently this just destroys the demuxer and recreates it. Ideally,
libff should have some functions to allow a more optimal means of doing
those things.
Reactors a bit of code related to starting up FFmpeg and makes it so the
initial view for the media source's properties displays the most
commonly desired settings.
Instead of the media source properties showing the URL mode by default
along with a whole bunch of properties that are confusing to most users,
starts on file mode and changes defaults to be a bit more sensible
related to file input.
Also, as a temporary measure for fixing color format issues (some video
files would display their color information incorrectly), forced format
conversion is now enabled by default, and has been moved to advanced
settings. Ideally, the actual bug causing color format issues in either
media-io or libff should be fixed at some point.
When browsing for a file, it would also just use *.* for the file
filter, which is a pain to use. This has been changed to use a
reasonable file filter related to common video/audio files so you don't
have to wade through non-media files just to select a media file. A
filter to show all files is still available as well.
Prevents it from loading the entire image in the graphics thread, and
allows for animated gifs in the filter (not that anyone would ever do
that. ..right?)
Fixes what is arguably the most annoying feature of the mask/blend
filter, the fact that the image always stretches to the entire source.
It now centers and preserves aspect ratio by default, with an option to
make it stretch and discard aspect ratio to make it operate as it did
before.
Images continually loading/unloading every time transitioning occurs
adds a lot of unnecessary transition lag. The user can always change
this value manually and/or use scene collections, so change the default
setting to make it not unload/reload by default feels a bit more safe.
This is probably not necessary but might fix an issue where errors pass
through to other parts of the program, possibly causing the crash on
exit related to the xcomposite capture.
Some games don't catch GL errors via glGetError, so there's a
possibility that an error will pass through to the capture calls,
causing a false failure.
The most simple solution is to just clear the error flag on each capture
call.
To first render the filter, the width/height values must be set, but
currently they're only set in the render function, which means that the
crop filter can never be rendered when the program first starts up.
This would cause the filter to fail to render at all under those
circumstances.
This patch moves the calculations from render to tick to ensure that
they're always called and the values are always set.
The virtual address table values for Reset/ResetEx can sometimes point
to functions that are in libraries outside of D3D8.dll and D3D9.dll, and
will cause a crash if used. Instead, just hook Reset/ResetEx when one
of the Present* functions are called.
Not calling recv when data is received will accumulate data in the
internal recveive buffer until it's full, in which case is will stop
acknowledging. This can lead to unjustified disconnections.
If there was an attempt to destroy the rtmp-stream output while it was
already connecting and stopping at the same time, it would try to join
with the stop thread rather than with the connect thread. The connect
thread would then continue past destruction.
Sometimes stopping a connection can lock up due to data that still
remains to be sent, and this would lock up the thread requesting the
stop (typically the UI thread). So instead of locking up the calling
thread, spawn a new thread specifically for stopping so the calling
thread can continue uninterrupted. If the user attempts to reconnect,
it will wait for the stop thread to complete in the connect thread
before attempting to connect.
API removed:

API added:
--------------------
gs_effect_t *obs_get_base_effect(enum obs_base_effect effect);
Summary:
--------------------
Combines multiple near-identical functions into a single function with
an enum parameter.
Use explicit UTF-8 byte sequence for the "no-break space" character.
Prevents issues with certain editors, and fixes the following compiler
warning on Visual C++:
warning C4819: The file contains a character that cannot be represented
in the current code page (X). Save the file in Unicode format to prevent
data loss
This replaces the name-based detection of the 4K intensity pro, and
allows other devices to be able to use the BGRA pixel format, if the
user so chooses.
Another thread could be manipulating the active_log_contexts array while the current thread is trying to read it, resulting in an uninitialized memory crash as the da_push_back call was not protected by the mutex.
Polls for file changes like the text plugin does. This is an interim
solution; both the text plugin and image source should use a file
monitoring API, preferably implemented through libobs.
Closesjp9000/obs-studio#482
When using a text file with the source and the font face is changed, it
would cause it to fail to update the glyphs and text accordingly. It
would trigger an error jump at line 392 of text-freetype2.c, ultimately
resulting in the text to render garbled after that.
How to reproduce:
Set the source to get text from a file, then just change the font face
(but not the size or anything else).
When updating text from file periodically, newer glyphs that weren't
already cached would not end up being rendered. This fixes the issue by
calling cache_glyphs after the file has been updated.
How to reproduce the original issue:
Set a text-freetype2 source to load an english-only text file. Then
overwrite the text in the file with non-english characters. The
non-english characters will then fail to render.

Instead of using shell functions to get the windows system directory,
use the kernel32 functions (GetSystemDirectory and
GetSystemWow64Directory). Reduces a bit of unnecessary overhead.
This caches the font list data to a file to minimize load times. Font
data will be refreshed when any font files are added/removed, based upon
a checksum of the font file names and dates (if available).
Microphones and other input devices can often have bad or erroneous
timestamps. Although we handle bad timestamps much better in
obs-studio, there are still lingering issues that can crop up from time
to time with device QPC timestamps that leads to mic data not playing
back properly. It's best if it be off by default rather than on, which
will now cause it to use system timestamps for input devices by default.
This changes it to the same handling as OBS1 for this case.
The new 'offset' value was not being passed back to the caller, which
caused the caller to continue to use the old value and thus would cause
an invalid hook and crash.
The call to CoInitializeEx in the win-mf module caused some sort of
conflict with the decklink module, causing the decklink module to crash
on exit. Instead, let libobs handle COM initialization.
If the GL capture part of the game capture hook fails to initialized for
whatever reason, it will go in to an infinite reacquire loop. If it
fails to initialize shared texture capture, try shared memory capture
instead.
For game capture, if a game is running at for example 800 FPS and limit
capture framerate is off, it would try to capture all 800 of those
frames, dramatically reducing performance more than what would ever be
necessary.
When limit capture framerate is off, instead of capturing all frames,
capture frames at an interval of twice the OBS FPS, identical to how
OBS1 works by default. This should greatly increase performance under
that circumstance.
This also adds the ability to detect whether it stopped due to lack of
space or not -- particularly useful for the FFmpeg output due to
lossless file format support.
For the FFmpeg output, the encoder ids are sort of superfluous. They
really should be optional. If they're not set, it should use the
encoder name string instead to determine the ids automatically.
It seems that certain encoders (quicksync) do not have proper back-end
support in the windows media foundation libraries for certain CPUs.
Quicksync doesn't appear to support CPUs that are not haswell (4xxx) or
above. It's really annoying, but there's not much we can do about it
until we implement our own custom quicksync implementation.
This check simply makes it attempt to spawn an encoder to check to see
whether the encoder can actually be created before registering an
encoder.
