OBS Source code parsing one

OBS Source code parsing one OBS Overall Engineering Obs
OBS Program Interface, program entry, QT based Libobs
Core integrated encapsulation of OBS, integrated encapsulation of all third-party libraries Blake2
Hash algorithms are said to be faster and safer than sha-1 Coreaudio-encoder
Audio capture, encapsulation of CoreAudio calls Ffmpeg-mux
For FFmpeg encapsulation, re-use File-updater
Automatic upgrade Frontend-tools get-graphics-offsets
In the case of inbound, the D3D8,D3D9,DXGI function is obtained by the virtual table offset, which implements the API redirection, that is, replacing the original function with its own function.
Of course, there is also the need for inter-process communication, which is implemented using pipe in win-capture.
Two graphics rendering implementations, using the GPU, freeing up CPU pressure while improving rendering efficiency and quality. Using shader language rendering (fixed-point and slice shaders, controlling position vectors and color values separately, interested students can learn more about them). GPU Mapping Glad
OpenGL Package Graphics-hook
Hook graphics API for capturing software windows Image-source
Picture resource, motion diagram, multi-map slide show Inject-helper
Inject graphices-hook into other processes. Ipc-util
Inter-process communication, mainly encapsulates the pipe pipeline implementation, used in the hook game process, the transmission of raw picture data, so used. Jansson
