This prevents VideoFormat::Any from unintentionally selecting H264 when
MJPEG is the only other format available.
This fixes a bug where certain devices (Logitech C920 with latest
drivers) will only have H264 and MJPEG available, and using
VideoFormat::Any will then select H264 over MJPEG because it's the first
format value and has the same priority as MJPEG. So now, MJPEG will be
prioritized over H264 instead.
Full color range seems to be active when decoding video with FFMmpeg
even when partial is explicitly selected. This should keep the range
synchronized.
Request contexts don't appear to work with relative paths, only absolute
paths. This fixes the bug where when using portable mode,
cookies/session wouldn't save because obs_module_config_path() was
returning a relative path rather than an absolute path.
Browser panels were having their initial visibility state always being
set to false. This fixes that by only setting visibility state on
browser objects which explicitly call the visibility message (i.e. only
browser sources).
In newer CEF builds the http://absolute/ scheme handler factory seems to
never complete when accessing large media files due to an apparent bug
in the Chromium media player (XHR requests complete fine). At the same
time, file:// URLs are working just fine.
file:// URLs will be used where available (CEF 3440+) falling back to
BrowserSchemeHandlerFactory on older CEF versions.
This reverts commit 46c5780a77e761416a990d5680593ff3a47405fb.
This needs to be reverted for now because users who did not set a size
on it (left it at default and just stretched it) will now suddenly have
the source's size change out of nowhere. There needs to be backward
compatibility implementation for this.
Using WasHidden() for the purposes of visibility no longer can be relied
upon due to some sort of bug with OSR in Chromium. This issue does not
happen when using 3440. The browser works fine without WasHidden()
calls, so we must remove its usage or be forced to use 3440. For those
who need the visibility handling, an alternative will have to be used
once it's available.
Additionally, this reverts the failed workaround to use OBS FPS in place
of SignalBeginFrame() because that code is no longer needed due to the
WasHidden() removal.
Before, we were calling DestroyWindow on the browser panel HWND from the
CEF UI thread, which meant that the main program thread had to process
window messages in order for that message to successfully through as
DestroyWindow blocks on the WM_DESTROY/WM_NCDESTROY window messages.
Unfortunately, this also had the side-effect of processing all queued Qt
events, which, when called in the destructor of a window like this, can
result in undefined behavior; specifically crashes, which were occurring
due to this. Especially when browser panels were in docks and docked to
the main window.
So, instead of calling DestroyWindow in another thread and then
processing events in the main thread, call DestroyWindow directly in the
main thread to get WM_DESTROY/WM_NCDESTROY and only those processed on
the spot. This appears to fix the crashes due to the undefined
behavior when closing browser panels.
This fixes crashes that could occur while processing Qt events during a
source's destruction.
Originally the processEvents code was added to make sure that any window
messages being sent to the browsers were being processed by Qt.
However, that was only necessary for browser panels as they are actually
associated with windows/views. Browser sources are OCR, thus they do
not need this.
Fixes same issue as 5c04876de1, but reverts that and changes it so that
external_begin_frame_enabled is not used instead, which seems to fix
that issue.
CEF outputs multiple audio streams at once, and OBS was only able to
handle one at a time. This fixes it by using audio lines for each CEF
audio stream, and mixes them together itself.
The dynamic bitrate operates based upon estimating the current bitrate
output, and then adjusting the bitrate on the fly as necessary when
congestion is detected as a replacement for dropping frames.
This may still need adjustment, as it is difficult to accurately emulate
real-world frame drop scenarios. This does not currently drop frames at
all, and because of that, very high congestion may cause additional
stream delay to viewers (because data will be buffered), but from
limited testing, most congestion will not cause that and it can safely
recover pretty quickly without adding significant delay.
When doing the bitrate limit test, it can be useful to have the ability
to change the current maximum bitrate limit. This adds the ability to
press keys on windows (numpad 0-6) to change between bitrates. Numpad 0
being no limit, 1 being 1000, 2 being 2000, etc.
