In the media source, do not pre-cache frames if the source is set to
close the file when inactive because that setting is designed to allow
the file to be replaced by the user. If it's replaced, it can
unintentionally keep the old precache frame, playing the frame from the
older video when it starts up.
When the statistics window starts up for the first time, it reset values
at that very moment so that stray lagged frames due to OBS' startup
wouldn't be displayed. However, that's really a bad place to reset
those values because the user could want to view the stats window after
a long stream, and having those values reset when he/she views the
window for the first time would sort of make the point of viewing your
stats moot.
Instead, reset the values only when applicable, such as after OBSInit or
when video is reset.
I believe the issue with the next to impossible frame count to be an integer underflow, as in order to achieve those you'd have to have recorded for at least 345 days with 144 fps. So this commit fixes them by using a normal integer first and then deciding on the result if it should be used or be replaced with a 0.
When hooking DXGI-based graphics programs in the hook, the first hook
point is IDXGISwapChain::Present. To be able to initiate a capture, a
pointer to the device context that created the swap chain is required,
which can be retrieved via IDXGISwapChain::GetDevice. Determining
whether the device context was D3D10 or D3D11 has always been somewhat
of an issue due to D3D10 and D3D11 being nearly identical, as well as
their interoperability/interchangeability. The GetDevice function would
first be called with the UUID of ID3D10Device, then if that failed,
the UUID of ID3D11Device.
However, with certain specific D3D11 games, GetDevice would for some
unknown reason succeed with the UUID of ID3D10Device, which would cause
capture to fail. (Conversely, attempting to call GetDevice with the
UUID of ID3D11Device on a device that's actually ID3D10Device would
always succeed, so reversing the order of the test was not an option).
There were originally three known D3D11 games that would erroneously
succeed when querying a D3D10 device interface: Call of Duty: Ghosts,
Just Cause 3, and theHunter: Call of the Wild. All other known D3D11
games would work correctly. Because it was only these three games, a
hack was originally implemented in the form of an executable exception
list that would force them to capture D3D11.
Unfortunately, Oculus games are now failing under the same circumstance
as well, so a simple hack will no longer work. To fix this, a more
reliable method of detecting which context it is had to be discovered:
simply check the feature level using ID3D11Device::GetFeatureLevel. If
the feature level is D3D_FEATURE_LEVEL_11_0 or D3D_FEATURE_LEVEL_11_1,
the device is definitely a D3D11 device. Otherwise, continue the tests
as they were before. Successfully tested with many D3D10 games, many
D3D11 games, and especially those three D3D11 games that previously were
detected as D3D10 erroneously.
VS2017 supports this natively.
VS2015 and earlier can use this with the editorconfig extension.
Most other popular IDEs support this natively or via a plug-in.

Preloading is designed to overwrite the current internal render texture
of the source so it'll be ready to play the first frame right when the
source is first displayed.
However, When the media source is set to pause on the last frame, it
keeps that current render texture visible, so preloading it with the
first frame will essentially overwrite the current render, causing it to
inadvertently show and pause on the first frame rather than the last
frame. So instead, just disable preloading when the user has it set to
pause on the last frame.
The recent changes in 88ae9af causes av_read_frame to check for
m->stopping, and fail with AVERROR_EXIT if true, which would happen
after each reset. Moving mp_media_prepare_frames to a line after
m->stopping is reset to false fixes the issue.
With certain media files (wmv in particular), the very last frame will
have a timestamp of AV_NOPTS_VALUE. This could cause the media to stick
on that frame indefinitely. Instead, use the estimated next timestamp
that was calculated in the previous frame.
Media files that have a very low framerate or very long interval between
frames would cause the media playback to stall indefinitely until the
next frame is played. This adds a 200ms timeout to ensure that the
media can be destroyed without being forced to wait indefinitely for the
next frame.
I have always felt that the out of the box themes for OBS were quite
lacking, and have spent a lot of time going through and sorting out the
difficulties with the current setup. I've added a new themeID parameter to
several elements that were otherwise impossible to target with QSS in a
theme. Since Qt has pushed for the use of QML over QSS at this point,
these should be considered workarounds. Included is the theme I was
working on that can serve as a base. I'm hoping to encourage others to
make their own themes, so we can grow the available themes for OBS.
I am happy for any feedback on the theme itself, or other updates that
can me made to make creating new themes easier overall.
Certain functions such as avformat_open_input and av_read_frame can
block, causing the program to someone wait very long periods of time
when a network URL is used with the media source. The
interrupt_callback member variable in AVFormatContext allows safely
canceling IO operations when trying to shut down or stop the
media-playback interface.
(Note: This commit also modifies deps/media-playback)
Allows buffering network-based media sources where supported. Default
is two megabytes of buffering.
Currently, when media-playback is used with a network address, video has
to wait for the first keyframe before it starts decoding. This is
probably not wise because the first packet of video may contain
additional header information, and because audio is forced to wait and
buffer while waiting for a keyframe, potentially causing a lot of audio
to get backed up unnecessarily which could inadvertently cause sync or
audio playback issues.
So, instead of waiting for a keyframe before decoding starts, decode
right away, and make it wait for a keyframe before calling the video
callback instead.
When using the full installer, there'll be a section where you can
choose what to install -- one section is a tree view with a "plugins"
section, and in that section there's "Browser plugin" and "Realsense
plugin". Instead of superfluously saying "plugin" for each of those,
replace with "source" instead -- so browser source and realsense source.
Also somewhat helps prevent the user from getting confused and thinking
we're installing a browser or something.
Rename "Processor" to "CPU Name" and place it before the number of
cores. Log free RAM for *nix. Log CPU Speed on Linux and FreeBSD. Unify
processor logging on Linux and FreeBSD. Get physical and logical cores
on *nix.
Use the new os_get_logical_cores and os_get_physical_cores function from
commits 6fc74d6 and e4a64f0 to get CPU core counts on *nix systems.
When custom server is used, it would still use the "common" RTMP service
to cap its bitrate. So if Twitch was selected and you changed over to
custom RTMP server, it would still cap to Twitch's bitrate limits even
though you're not using Twitch anymore.
There's no need to reset vertex buffers like this anymore. This would
unintentionally cause certain things (such as the freetype text source
on windows) to stop rendering properly.
