During destruction of the QSV_Encoder_Internal the response may not be
initialized and we can segfault. Add a check for this similar to the
Windows implementation.
Pass down texture/host memory choice for fallback encoders. During
fallback we don't (can't) initialize a shared texture pool and should
use the regular host memory path.
This fixes usage on multi-GPU systems, and enables texture encoders.
On Windows 10 and up, D3D11 should never fail, so the D3D9 code should
no longer be possible to hit and should no longer be needed.
Revert "obs-qsv11: Use d3d9 allocator on Win7"
This reverts commit b276b1633e.
This reverts the changes to Windows where Release() was called every
time, since we need share a single DX context across multiple encoders.
Instead introduce a ReleaseSessionData() function and some platform
specific session data that will be passed to it. We use this to track
the VA-API display and fd to release them at the right time. Leaking
displays will also lead to cache pollution in the intel-media-driver
crashing users so we cannot do that.
fixes#9611
Trying to use the display server as the QSV device was found to be
generally wrong in beta, so instead lets save defaults from the earlier
device enumeration similar to obs-ffmpeg-vaapi which is known to work
well.
VPL does not have a consistent initialization process for the various
backends it dispatches to. So this resolves the new VPL dispatcher
failing to initialize the video session when it dispatches to
intel-mediaSDK backend. On the oneVPL-intel-gpu backend VA-API sessions
are correctly initialized so this wasnt noticed when tested on newer
hardware.
This moves the existing adapter checking into the platform layer and
moves the Windows implementation to its platform implementation and adds
a Linux implementation based on directly querying VA-API.
Unlike Windows, this check takes ~1ms so we have no need to spin out
another thread to perform the work. This also fixes up some of the CPP/C
mixing going on in common_utils."h" to allow us to call common functions
from C files.
