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, webrtc:13137 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}
WebRTC is a free, open software project that provides browsers and mobile applications with Real-Time Communications (RTC) capabilities via simple APIs. The WebRTC components have been optimized to best serve this purpose.
Our mission: To enable rich, high-quality RTC applications to be developed for the browser, mobile platforms, and IoT devices, and allow them all to communicate via a common set of protocols.
The WebRTC initiative is a project supported by Google, Mozilla and Opera, amongst others.
Development
