Currently the configuration\nsupports test patterns and images.\n\nIt passed the gitlab pipeline:\nhttps://gitlab.freedesktop.org/chenghaoyang/libcamera/-/pipelines/1278799\n\nI've also checked that it works on qcam.\n\nI failed to pass multi_stream_test when trying to enable multiple\nstreams though. Please give me some hints what it tests and what I\nmissed:\n```\n[295:43:43.910237144] [1441841] INFO IPAManager ipa_manager.cpp:137 libcamera is not installed.
