It's tested in one of the CrOS camera\ntast test: camera.Connector.\nThis patch fixes that by queueing one extra padding frame.\n\nPlease check. Thanks!\n\nBR,\nHarvey\n\nHarvey Yang (1):\n  libcamera: Fix ipu3's issue of first black frame\n\n src/libcamera/pipeline/ipu3/ipu3.cpp | 50 ++++++++++++++++++++++++----\n 1 file changed, 43 insertions(+), 7 deletions(-)"
