From 9217f274f64f690b768d332663e1731a3ee5ef15 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Niklas=20S=C3=B6derlund?= Date: Fri, 22 Nov 2019 16:22:56 +0100 Subject: libcamera: Switch to FrameBuffer interface MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Switch to the FrameBuffer interface where all buffers are treated as external buffers and are allocated outside the camera. Applications allocating buffers using libcamera are switched to use the FrameBufferAllocator helper. Follow-up changes to this one will finalize the transition to the new FrameBuffer interface by removing code that is left unused after this change.
