Subject: [PATCH 06/14] waylandsink: always select dmabuf buffer pool
|
|
|
|
Force usage of dmabuf buffer pool by default, ie
|
|
even if video/x-raw(memory:DMABuf) is not set in caps.
|
|
This allows 0-copy path with software downstream elements
|
|
(use of dmabuf buffers mmapped memory directly instead
|
|
of copying).
|
|
|
|
