Jonas Ådahl	f2c4452e8d	stream: Make capability device IDs an JSON object ... Also change the encoding of the byte array to use hexadecimal encoding, i.e. the byte array [100, 200] in becomes "64c8".	2026-01-22 16:08:19 +00:00
Jonas Ådahl	8600721de0	stream: Change PW_CAPABILITY_DEVICE_ID_NEGOTIATION to a version number ... This allows easier evolvement of the negotiation protocol.	2026-01-22 16:08:19 +00:00
Jonas Ådahl	58b958860e	stream: Add DRM device negotiation ... A DMA buffer from a DRM device are typically accessed using API related to a DRM device, e.g. Vulkan or EGL. To create such a context for using with a PipeWire stream that passed DRM device DMA buffers applications have so far usually guessed or made use of the same context as the stream content will be presented. This has mostly been the Wayland EGL/Vulkan context, and while this has most of the time worked, it's somewhat by accident, and for reliable operation, PipeWire must be aware of what DRM device a DMA buffer should be accessed using. To address this, introduce device ID negotation, allowing sources and sinks to negotiate what DRM device is supported, and what formats and modifiers are supported by them. This will allow applications to stop relying on luck or the windowing system to figure out how to access the DMA buffers. It also paves the way for being able to use multiple GPUs for different video streams, depending on what the sources and sinks support.	2026-01-14 08:15:43 +00:00

Wim Taymans	8edb6fc8b2	doc: add some small docs updates ... Note that the sync_timeline metadata might add 2 fds, which are then not part of the dma-buf planes.	2024-08-21 11:01:54 +02:00
Pauli Virtanen	77fad4ee13	doc: reorganize files ... Separate various autogen files from the documentation .dox files. Rename .dox files to match the intended tree structure.	2023-11-19 16:39:15 +00:00
