From c54b8d2fc79c684deacc81a94f6baa1cb56c62be Mon Sep 17 00:00:00 2001 From: Tomi Valkeinen Date: Wed, 27 Sep 2023 17:18:09 +0300 Subject: [PATCH] media: rp1: cfe: Dual purpose video nodes The RP1 CSI-2 DMA can capture both video and metadata just fine, but at the moment the video nodes are only set to support either video or metadata. Make the changes to support both video and metadata. This mostly means tracking both video format and metadata format separately for each video node, and using vb2_queue_change_type() to change the vb2 queue type when needed. Briefly, this means that the user can get/set both video and meta formats to a single video node. The vb2 queue buffer type will be changed when the user calls REQBUFS or CREATE_BUFS ioctls. This buffer type will be then used as the "mode" for the video node when the user starts the streaming, and based on that either the video or the meta format will be used. A bunch of macros are added (node_supports_xxx()), which tell if a node can support a particular mode, whereas the existing macros (is_xxx_node()) will tell if the node is currently in a particular mode. Note that the latter will only work correctly between the start of the streaming and the end of the streaming, and thus should be only used in those code paths. However, as the userspace (libcamera) does not support dual purpose video nodes, for the time being let's keep the second video node as V4L2_CAP_META_CAPTURE only to keep the userspace working.
