In particular,\nI've switched back to using utils::Duration to store the timeout value in the\nv4l2_videodevice class. However, because of this change, I have to do a slightly\nawkward cast when setting the Timer value:\n\nwatchdog_.start(std::chrono::duration_cast<std::chrono::milliseconds>(watchdogDuration_));\n\nThis is becase the base type of utils::Duration whereas std::chrono::milliseconds\nuses an integer, and you are not allowed an implicit conversion between the two.\nOnce we switch utils::Duration to use an integer base type, implicit conversions\nwill be possible, and we can get rid of the above cast. Does that seem reasonable?\n\nThanks,\nNaush\n\nKieran Bingham (1):\n test: v4l2_videodevice: Verify the Dequeue Watchdog\n\nNaushir Patuck via libcamera-devel (2):\n libcamera: v4l2_videodevice: Add a dequeue timer\n pipeline: raspberrypi: Add a Unicam dequeue timeout\n\n include/libcamera/internal/v4l2_videodevice.h | 10 ++\n include/libcamera/ipa/raspberrypi.mojom | 1 +\n src/ipa/raspberrypi/raspberrypi.cpp | 2 +\n .../pipeline/raspberrypi/raspberrypi.cpp | 15 +++\n src/libcamera/v4l2_videodevice.cpp | 55 +++++++++++\n test/v4l2_videodevice/dequeue_watchdog.cpp | 96 +++++++++++++++++++\n test/v4l2_videodevice/meson.build | 1 +\n 7 files changed, 180 insertions(+)\n create mode 100644 test/v4l2_videodevice/dequeue_watchdog.cpp" }
