I have gotten zero failues and\n2 warnings with a uvcvideo libcamera camera. The two warnings are that\nVIDIOC_S_FMT doesn't work from a second fd (after a different fd has\nalready called it), and that VIDIOC_CREATEBUFS is not supported, which I\nthink are fair to not support.\n\nNote that there are a couple failues when using a vimc libcamera camera,\nas these cameras doesn't support setting frame sizes that are not\nmultiples of 3.\n\nAlso, while trying to comply with v4l2-compliance I lost support for\nfirefox. I'll look into this. qv4l2 still works, though.\n\n\nPaul Elder (15):\n v4l2: v4l2_compat: Support multiple open\n v4l2: v4l2_camera_proxy: Check for null arg values in ioctl handlers\n v4l2: v4l2_camera_proxy: Fix v4l2-compliance support for extended\n formats\n v4l2: v4l2_camera_proxy: Implement VIDIOC_G/S_PRIORITY\n v4l2: v4l2_camera_proxy: Implement VIDIOC_ENUMINPUT, VIDIOC_G/S_INPUT\n v4l2: v4l2_camera_proxy: Implement VIDIOC_ENUM_FRAMESIZES\n v4l2: v4l2_camera_proxy: Fix v4l2-compliance format tests\n v4l2: v4l2_camera: Re-validate configuration after adjusted\n v4l2: v4l2_cammera_proxy: Reset buffer flags on streamoff when already\n off\n v4l2: v4l2_camera_proxy: Call streamoff on reqbufs 0\n v4l2: v4l2_camera: Don't use libcamera::Semaphore for available\n buffers\n v4l2: v4l2_camera_proxy: Add sequence number\n v4l2: v4l2_camera: Clear pending requests on freeBuffers\n v4l2: v4l2_camera_proxy: Check arg->index bounds for querybuf, qbuf,\n dqbuf\n v4l2: v4l2_camera_proxy: Fix v4l2-compliance streaming tests\n\n src/v4l2/v4l2_camera.cpp | 53 +++-\n src/v4l2/v4l2_camera.h | 9 +-\n src/v4l2/v4l2_camera_proxy.cpp | 435 ++++++++++++++++++++++++++-----\n src/v4l2/v4l2_camera_proxy.h | 58 +++--\n src/v4l2/v4l2_compat_manager.cpp | 25 +-\n 5 files changed, 477 insertions(+), 103 deletions(-)"}
