Specifically, it allows to map V4L2_PIX_FMT_JPEG\nand V4L2_PIX_FMT_MJPEG to libcamera::formats::MJPEG.\n\nThe series starts by allowing to associate mulitple V4L2 FourCC in\nPixelFormatInfo and re-introduces toV4L2PixelFormat() in V4L2VideoDevice in\norder to select among from the list of V4L2 formats the first one supported\nfrom the video device.\n\nPatch [7/8] adds a multiplanar flag to V4L2VideoDevice::toV4L2PixelFormat() to\nallow selection of the contiguous or non-contiguous format versions.\n\nFinally, the last patches associate V4L2_PIX_FMT_JPEG to formats::MJPEG in\nthe libcamera::formats enumeration and the conversely maps formats::MJPEG to\nV4L2_PIX_FMT_JPEG in the V4L2 formats enumeration.\n\nTested with a UVC camera and on pinephone where the format is correctly mapped\n\nv1->v2:\n- Add a missing conversion using the video device in Simple converter\n- Map formats::MJPEG to V4L2_PIX_FMT_JPEG in v4l2 formats enumeration\n\nJacopo Mondi (8):\n libcamera: formats: Support multiple V4L2 pixel formats\n libcamera: formats: Search PixelFormatInfo on multiple formats\n libcamera: v4l2_pixelformat: Return a format list in fromPixelFormat()\n libcamera: v4l2_videodevice: Reintroduce toV4L2PixelFormat()\n libcamera: v4l2_videodevice: Match formats supported by the device\n libcamera: v4l2_videodevice: Add multiplanar argument to\n toV4L2PixelFormat\n libcamera: formats: Map V4L2_PIX_FMT_JPEG to formats::MJPEG\n libcamera: v4l2_pixelformat: Map formats::MJPEG to V4L2_PIX_FMT_JPEG\n\n Documentation/guides/pipeline-handler.rst | 7 +-\n include/libcamera/internal/formats.h | 4 +-\n include/libcamera/internal/v4l2_device.h | 1 +\n include/libcamera/internal/v4l2_pixelformat.h | 6 +-\n include/libcamera/internal/v4l2_videodevice.h | 9 +-\n src/libcamera/formats.cpp | 262 +++++++++---------\n src/libcamera/pipeline/ipu3/cio2.cpp | 2 +-\n src/libcamera/pipeline/ipu3/imgu.cpp | 2 +-\n .../pipeline/raspberrypi/raspberrypi.cpp | 34 ++-\n src/libcamera/pipeline/rkisp1/rkisp1_path.cpp | 6 +-\n src/libcamera/pipeline/simple/converter.cpp | 10 +-\n src/libcamera/pipeline/simple/simple.cpp | 4 +-\n src/libcamera/pipeline/uvcvideo/uvcvideo.cpp | 6 +-\n src/libcamera/pipeline/vimc/vimc.cpp | 8 +-\n src/libcamera/v4l2_device.cpp | 15 +\n src/libcamera/v4l2_pixelformat.cpp | 20 +-\n src/libcamera/v4l2_videodevice.cpp | 41 ++-\n src/v4l2/v4l2_camera_proxy.cpp | 6 +-\n test/libtest/buffer_source.cpp | 2 +-\n 19 files changed, 261 insertions(+), 184 deletions(-)\n\n--\n2.37.1" }
