Request / response latency dominates the download time of small
files and patches, especially the locale files. Increasing this to
4 doesn't consume many more resources and basically doubles the
download speed, especially on higher latency connections.
Unfortunately WinHTTP doesn't support multiplexing with HTTP2, but there
is still some minor benefit to enabling it. Windows 10 21H1 will enable
TLS 1.3 client support in Schannel, so let's get ready for it.
On a modern Windows OS, you can rename an in-use file despite not being
able to write to it. With the introduction of the virtual camera, it is
now quite common that users will have in-use files when updating. This
commit renames in-use files, allowing the new version to be installed.
Upon a reboot, the previously in-use file will be deleted.
With the queued connection in d68484e7, the "Deselect" signal for
sources which are being deleted is never fired, as the object is gone by
the time the queued signal is processed. This results in the context bar
not updating.
This commit adds a new UpdateContextBarDeferred function, allowing
queuing of only the context bar update instead of the whole signal
handler.
If the user hasn't specifically set a rate control and left OBS at the
default of CBR, the settings loaded by GetDataFromJsonFile will not have
a rate_control parameter present. This causes the replay buffer to think
the user is in VBR mode and use the wrong settings for determining
maximum buffer size. Fixes#2516.
The (de)select signal can come from a obs_scene_enum_items
which locks the scene. The Qt::QueuedConnection makes sure
the (de)select is handled outside of that lock.
Fixes the deadlock from #3673
The vod track in advanced output mode would be overwritten by twitch
soundtrack's vod track. Additionally, simple output mode would overwrite
twitch's soundtrack vod track even when vod track was turned off in
settings.
So instead, if vod track is off, don't clear the secondary encoder
unless it's explicitly our encoder. Additionally, make sure that
advanced output mode's vod track encoder behaves consistently with
simple output mode's vod track so it doesn't get overwritten.
This setting, although technically different from the one in the
streaming section of settings, is superseded by that setting.
The setting can still be used via ini file if an actual custom rate
control or keyframe interval is needed.
The Scene Collection Importer would attempt to set the new filename
using the name property of the scene collection. However, it would
determine an unused filename, and then replace spaces with underscores,
which could cause a name collision. This changes the importer to replace
spaces with underscores first for the base filename, and then determine
an unused filename.
This commit fixes various issues with screen readers in the main OBS
interface. These were tested using NVDA on Windows 10 2004.
Audio track selection in Settings now says Track 1, 2, etc, rather than
just the number.
Various checkboxes that just say "Enable" now have accessible text that
says what the enable is for (since it says "checkbox", the fact it's an
enable should hopefully be clear).
Type in the recording tab of output now has accessible text which says
"Recording Type".
Items in the Advanced Audio Properties window now have accessible text
for what they are for. Currently some do not report correct values, but
that will require an accessible interface in Qt to be written
specifically for that, which will be done at a later date.
Buttons in the filters window now have accessible text for what they do.
All the right side buttons in hotkeys now have tooltips, and by
extension, accessible text.
Speeds up loading with large number of filters and prevents deadlock by
not getting the properties of filters during
OBSBasicFilters::UpdateFilters() which uses the source->filter_mutex
This significantly simplifies the
configuration setting's initial load.
This also fixes as issue where the source toolbar
would initialise as "TextLabel" with enabled
buttons if the user had not yet toggled the setting.
Fixes#3722
The Elgato Streamdeck plugin ships their own Qt5Network.dll on Windows,
which may be ABI incompatible with newer Qt DLLs if we decide to update
our Qt version. So to prevent that plugins (and other plugins) from
using their Qt5Network.dll, we need to explicitly load our
Qt5Network.dll first so that we can prevent it from trying to load
theirs beforehand.
For context on this, previously, we didn't ship Qt5Network on Windows
because we would have to ship OpenSSL with it, but we didn't want to
ship it without SSL support. Because of that, Elgato's Streamdeck plugin
would ship their own Qt5Network.dll library (that didn't have SSL
support anyway). However, Qt recently added support for windows
schannel, which allows SSL support via the Windows API, making it so we
don't have to ship extra libraries to get SSL. So now we can start
shipping Qt5Network without worry.
Detect other instances of the obs by creating an extra dummy thread,
named "OBS runonce". The process of threads enumeration of current user
is guarded by an O_EXLOCK file advisory lock when opening the lock file.
Such file lock would be dropped once the thread name is changed.
This should be usable on FreeBSD and possibly compile on DragonFly BSD.
fixes: #3053
If a service has a maximum resolution and/or maximum framerate, shows
that to the user in the stream section of settings where the maximum
video/audio bitrate are shown.
Allows services to limit and enforce resolution and framerate values the
user can select in the UI if "ignore service recommendations" is not
checked. If the "ignore service recommendations" option is not checked,
the user will not be able to select or use a resolution and/or framerate
in the user interface that the service does not support. If "ignore
service recommendations" is checked, it will work as it normally would,
allowing any value to be used as per normal.
Fortunately, and hopefully for the foreseeable future, there is only one
service that enforces resolutions and framerates.
(This commit also modifies rtmp-services and UI)
Changes the maximum resolution size to a resolution list, and splits the
maximum FPS to its own function.
(Note: ABI has not been modified because the last changes still haven't
been released yet, so it's safe to modify this as long as the changes
haven't been officially released)
