obs_encoder_getdisplayname declaration was not changed to match the
definition (obs_encoder_get_display_name) when the API consistency
update occurred.
On i3wm, windows aren't unmapped when switching away from a window's
workspace, but it does cause OBS to lose the capture. Because
switching back will not trigger a MapNotify, the capture fails to
restart unless you resize or move the window (ConfigureNotify). An
Expose event is fired by the wm, however, so catching this correctly
restarts the capture.
Refactor the screen enumeration code a little to make sure xinerama is present
and active before using it. If the extension is present but not active it will
no longer fail.
This adds support for the AverMedia C985 encoder (which is available on
C985 capture cards) as well as the C353 hardware encoder (which is
currently available on the X99S Gaming 9 motherboards).
These encoders have some limitations, such as limited resolutions
(1280x720 and 1024x768), a max GOP size of 30, and the encoder format
only supports YV12, which requires conversion if the current output
format isn't the same. The C985 and C353 encoders seem to be pretty
much identical, although it seems like the C353 has a bit more efficient
encoding.
I don't believe these are really suitable for streaming, as they do not
really have the encoding efficiency needed to stream at lower bitrates,
and seem to only support variable bitrate. However, for recording these
encoders are quite nice to have available, and work quite well.
The main module code was originally all packed in to the win-dshow.cpp
file, which isn't exactly ideal or clean if one wants to add other
things to the module as a whole.
Previously, due to a bug in libdshowcapture, the NV12 format was
actually being used for YV12 erroneously, and no actual support for YV12
existed. This fixes the bug with NV12 and adds support for YV12.
Waiting for the first packet to arrive before sending the headers helps
prevent issues with certain types of encoders that may not get their
header/SEI until the first packet has been received.
If an encoder did not possess any SEI data, it would never send data at
all because the sent_first_packet wasn't set despite the first packet
being sent.
Added obs_avc_keyframe that returns whether an avc packet is a keyframe
or not. This function is particularly useful for when writing custom
encoder plugins.
I encountered some cases where I needed to use these enumerations
outside of the file, so this allows other modules to use AVC
enumerations without having to redefine them each time. Especially
useful for custom encoder modules.
I neglected to surround some files with extern "C", so if something
written with C++ used the files it would cause function exports to not
be mangled by it correctly.
This adds bicubic and lanczos scaling capability to libobs to improve
scaling quality and sharpness when the output resolution has to be
scaled relative to the base resolution. Bilinear is also available,
although bilinear has rather poor quality and causes scaling to appear
blurry.
If the output resolution is close to the base resolution, then bilinear
is used instead as an optimization, as there's no need to use these
shaders if scaling is not in use.
The Bicubic and Lanczos effects are also exposed via exported function
to allow the ability to use those shaders in plugin modules if desired.
The API change adds a variable 'scale_type' to the obs_video_info
structure that allows the user interface to choose what type of scaling
filter should be used.
Copying this binary is kind of unnecessary because it's something that
everyone has as long as they update DirectX, and isn't something we can
distribute because it's a Microsoft DLL.
Remove the update time check from the volume meter since it is no longer
nescessary. The update interval can now be set with the volmeter which has
the added benefit of not loosing data where previously updates had been
skipped.
Remove the calculation of volume levels and the corresponding signal
from obs_source since this is now handled in the volume meter.
Code that is interested in the volume levels can either use the
volmeter provided from obs_audio_controls or use the audio_data signal
to gain access to the raw audio data.
Signal updated volume levels when they become available in the volume
meter. The frequency of the updates can be adjusted by setting a
different update interval.
Remove the the signal handler for the volume_level signal of audio
sources from the volume meter in anticipation of using the levels
calculated in the volume meter itself.
Add a property to the volume meter that specifies the length of the
interval in which the audio data should be sampled before the
audio_levels signal is emitted.
This adds a new signal to (audio) sources which is emitted whenever new
audio data is received from the source. This enables other code that is
interested in the raw audio data to directly access it when it becomes
available.
This causes x264 to use the currently set color space and color range
of the video media. This helps prevent issues with decoding where the
colors wouldn't look right due to the fact that these settings were
never specified to x264, and prevents darkness and brightness from
looking washed out due to a potentially incorrect color range.
This was an important change because we were originally using an
hard-coded 709/partial range color matrix for the output, which was
causing problems for people wanting to use different formats or color
spaces. This will now automatically generate the color matrix depending
on the format, color space, and range, or use an identity matrix if the
video format is RGB instead of YUV.
This adds the windows version of game capture.
New features:
- An option to hook any fullscreen application automatically (that
doesn't have borders) so that no specific window configuration is
required. Definitely a sorely needed feature
- An option to force memory capture for the sake of compatibility with
things such as SLI, multi-adapter setups (usually laptops), as well as
the ability to be used with the OpenGL renderer
- An optimization option to force scaling on the GPU before texture
transfer, reducing the transfer bandwidth (which is especially
important for compatibility capture)
- An optimization option to limit framerate to the current OBS framerate
to improve capture performance (mostly useful for compatibility
capture)
- An option to capture third-party overlays (such as steam)
- Logging improvements, game capture log will now be sent via pipe
instead of written to a separate file, making diagnosing problems a
little bit easier
This library is a completely refactored and rewritten version of the
original graphics hook. The code is more clean, readable, and has a
variety of new features, such as scaling and forcing memory capture.
Currently, only D3D9, 10, and 11 are implemented. (This commit may be
updated on this branch)
Before, game capture would find addresses to important graphics
functions by creating a graphics context for the desired API inside of
the hook, and then find the function addresses that way.
The big problem with that is that the context could often cause the
hooked application to crash, especially if another hook was active.
This bypasses that entire need by a simple console application that
creates the contexts, finds the hook address offsets and then returns
them via console output.
This header contains global defines, structures, and helper inline
functions for the graphics hook that will be shared between game
capture, the hook, and the get-graphics-addrs helper application.
