I logged the messages below when qcam running.\nhttps://pastebin.linaro.org/view/20d91f21\nIn 1280x800 mode:\nformat convert by CPU is around ~4 fps, rendering by GPU up to ~30.0 fps\nIn 1920x1080 mode:\nformat convert by CPU is around ~2 fps, rendering by GPU still up to ~30.0 fps\n\n The improvement still in progress, including more YUV formats support ... etc.\nAnd some parts I added are not in good shape, I am trying to make it better. \nSo I appreciate any review conments and suggestion.\n\nIt's also available on below.\nhttps://github.com/showliu/libcamera/commits/qcam_opengl_hack2\n\nI tested with kernel 5.5rc5 + Panfrost GPU driver on Rock Pi 4B platform.\n\nShow Liu (3):\n qcam: Added statusbar to show the camera stream configuration\n qcam: Added opengl widget class for qcam\n qcam: added an option to enable rendering via OpenGL shader\n\n src/qcam/glwidget.cpp | 213 +++++++++++++++++++++++++++++++++++++++\n src/qcam/glwidget.h | 76 ++++++++++++++\n src/qcam/main.cpp | 2 +\n src/qcam/main_window.cpp | 36 ++++++-\n src/qcam/main_window.h | 3 +\n src/qcam/meson.build | 4 +-\n 6 files changed, 330 insertions(+), 4 deletions(-)\n create mode 100644 src/qcam/glwidget.cpp\n create mode 100644 src/qcam/glwidget.h" }
