This is a reland of f2177f6612079ccce9c320ea7e77bc934c684f5c Original change's description: > PipeWire capturer: implement proper DMA-BUFs support > > Currently both KWin (KDE) and Mutter (GNOME) window managers don't > use DMA-BUFs by default, but only when client asks specifically for > them (KWin) or when experimental DMA-BUF support is enabled (Mutter). > While current implementation works just fine on integrated graphics > cards, it causes issues on dedicated GPUs (AMD and NVidia) where the > code either crashes or screensharing is slow and unusable. > > To fix this, DMA-BUFs has to be opened using OpenGL context and not > being directly mmaped(). This implementation requires to use DMA-BUF > modifiers, as they are now mandatory for DMA-BUFs usage. > > Documentation for this behavior can be found here: > https://gitlab.freedesktop.org/pipewire/pipewire/-/blob/master/doc/dma-buf.dox > > Bug: chromium:1233417 > Change-Id: I0cecf16d6bb0f576954b9e8f071cab526f7baf2c > Reviewed-on: https://webrtc-review.googlesource.com/c/src/+/227022 > Commit-Queue: Tommi <tommi@webrtc.org> > Reviewed-by: Tommi <tommi@webrtc.org> > Reviewed-by: Erik Språng <sprang@webrtc.org> > Cr-Commit-Position: refs/heads/main@{#34889} Bug: chromium:1233417 Change-Id: I308501d86ec18ab6df9bcee569c4b72df7926549 Reviewed-on: https://webrtc-review.googlesource.com/c/src/+/231180 Reviewed-by: Erik Språng <sprang@webrtc.org> Reviewed-by: Tommi <tommi@webrtc.org> Commit-Queue: Tommi <tommi@webrtc.org> Cr-Commit-Position: refs/heads/main@{#35152}
