The `MediaEntity` class was\nnever meant to handle the cases required for e.g. libusb. Additionally\nthe current way matching is handled is insufficient for (future)\n`MediaDevices` in which a specific key/value relationship exists\nfor properties (e.g. USB vid and pid).\n\nTo solve these two problems I've abstracted away the requirements for\nentities that `DeviceMatch` requires in `DeviceMatchEntityInterface`\nand extended `DeviceMatch` to handle key/value pairs. Using \"*\" as a\nkey is currently a catch all for the presumably keyless property of\nV4L2 `MediaEntity`.\n\nSophie Friedrich (1):\n libcamera: enumeration: Generalize DeviceMatch\n\n .../libcamera/internal/device_enumerator.h | 16 +--\n include/libcamera/internal/device_match.h | 46 +++++++\n include/libcamera/internal/media_device.h | 1 +\n include/libcamera/internal/media_object.h | 7 +-\n include/libcamera/internal/meson.build | 1 +\n src/libcamera/device_enumerator.cpp | 73 ----------\n src/libcamera/device_match.cpp | 126 ++++++++++++++++++\n src/libcamera/meson.build | 1 +\n 8 files changed, 183 insertions(+), 88 deletions(-)\n create mode 100644 include/libcamera/internal/device_match.h\n create mode 100644 src/libcamera/device_match.cpp" }
