Patch 2/3\nfirst prepares the ViewFinder base class, and patch 3/3 then addresses\nthe GL viewfinder. Only the Y'CbCr encoding and quantization range are\ntaken into account so far, support for the transfer function and primary\ncolor chromaticities is left for later.\n\nLaurent Pinchart (3):\n pipeline: uvcvideo: Add color space support\n qcam: Pass color space to ViewFinder::setFormat()\n qcam: viewfinder_gl: Take color space into account for YUV rendering\n\n src/libcamera/pipeline/uvcvideo/uvcvideo.cpp | 5 ++\n src/qcam/assets/shader/YUV_2_planes.frag | 27 ++++---\n src/qcam/assets/shader/YUV_3_planes.frag | 23 +++---\n src/qcam/assets/shader/YUV_packed.frag | 17 ++--\n src/qcam/main_window.cpp | 6 +-\n src/qcam/viewfinder.h | 2 +\n src/qcam/viewfinder_gl.cpp | 82 +++++++++++++++++++-\n src/qcam/viewfinder_gl.h | 3 +\n src/qcam/viewfinder_qt.cpp | 5 +-\n src/qcam/viewfinder_qt.h | 1 +\n 10 files changed, 134 insertions(+), 37 deletions(-)" }
