Subject: [PATCH 2/2] loader/dri3: import prime buffers in the currently-bound
|
||
|
|
screen
|
||
|
|
|
||
|
|
This tries to mirrors the codepath taken by DRI2 in IntelSetTexBuffer2()
|
||
|
|
and fixes many applications when using DRI3:
|
||
|
|
- Totem with libva on hw-accelerated decoding
|
||
|
|
- obs-studio, using Window Capture (Xcomposite) as a Source
|
||
|
|
- gstreamer with VAAPI
|
||
|
|
|
||
|
|
v2:
|
||
|
|
- introduce get_dri_screen() in the dri3 loader's vtable (krh)
|
||
