[vlc-devel] [PATCH 3.0 2/4] direct3d11: don't lock the ID3D11VideoContext when waiting for the query to finish

[Steve Lhomme]

This leaves some time for the decoder to do things.

This is how it was before 42011b9fb105b4b5de832fdafd097b86c8154eda.

Fixes #25728

(cherry picked from commit 4cb73cccce3a413263b697b88acafe172978c325) (edited)
edited:
- the display callback is in a different location
- the d3d_dev is not a pointer
