From afd7ad5f9dbef7f31162b9a49b9f85c0a309a3a0 Mon Sep 17 00:00:00 2001 From: Daniel Scally Date: Fri, 13 Jan 2023 16:27:10 +0000 Subject: lib/video-source: Add video_source_import_buffers We need to be able to place encoded data into the sink device's bufs. To facilitate that add a video_source operation that allows the source to import buffers from the sink. Add a .import_buffers() callback so that the libcamera-source can access a sink's buffers.
