As Intel continues to add discrete graphics cards, maintaining a long
list of discrete device IDs to check against isn't wise. When i+I
platforms are detected, default to integrated graphics.
Enables a pipeline for texture-based encoding with QSV. Utilizes OBS
NV12 output for encode to avoid offloading them from GPU, which will
increase performance. The option to select old QSV pipeline still
remains and will fallback if new pipeline fails.
Code submissions have continually suffered from formatting
inconsistencies that constantly have to be addressed. Using
clang-format simplifies this by making code formatting more consistent,
and allows automation of the code formatting so that maintainers can
focus more on the code itself instead of code formatting.
This reverts commit 3c22cf35c9, reversing
changes made to c7dab6c92b.
This is being reverted due to many people being unable to start up the
QSV encoder with these changes.
- Allow user to change # of B frames. New Default -> 1
- Allow user to enable Content Adaptive Quantization (MBBRC) if CPU is Skylake or newer.
- Allow user to choose LA_CBR as a rate control.
- LA depth: New Default -> 15, only when LA rate control is used.
Allow multiple QSV encoders, usefull for live + recorded parallel
sessions. The first QSV encoder will create a DirectX device and return
a handle / pointer. Any additional QSV encoder will use that same
pointer to the DirectX device. We keep track of the number of open
QSV encoders so that we wait to close the DirectX resources after all
encoders are closed.
Closesobsproject/obs-studio#1341
Currently, multiple QSV encoders cannot be active at the same time
(otherwise it will crash). This is a temporary solution to prevent
crashes from occurring when more than one QSV encoder tries to start up
at the same time.
Additionally, in the future there should be a way for encoders to be
able to communicate with the front-end when an error such as this
occurs.
