PR #1937 (commit b9ad1ce) added QSV target usage options, but there was
a comma missing between two of the array entries. This resulted in
"faster" and "veryfast" becoming "fasterveryfast", which is not valid.
Code style changes were required by .clang-format.
Add the option to enable custom quantization matrix for game streaming
on ICL for better subject quality. Feature is only supported with AVC
high profile, so added function to detect when QSV profile is modified
and hide or show CQM UI option accordingly. Also, increase SPS/PPS
buffer sizes since matrix is stored in SPS/PPS.
Enable B-Pyramid frames to improve quality for high motion content.
B-pyramid allows a B-frame to choose closer frames for reference which
may have higher correlation.
Adjusts packet priority to avoid dropping referable B-frames
A check has been added to ensure feature is enabled only on platforms
with MSDK API 1.8 or higher - addresses crashing issues.
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 patch fixes QSV failing with new DCH graphics drivers. QSV is not
initializing under certain conditions when the graphics adapter 0 is not
set to iGFX due to outdated MSDK dispatcher. Updating to MSDK with new
dispatcher to enable proper initialization of QSV encoder with DCH
drivers.
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.
