This patch\nprovides a converter class (inherited from V4L2M2MConverter).\n\nThe DW100 dewarp engine has scaling capabilites and can be used\nto set crop rectangles in the rkisp1 pipeline handler. Plumbing\nin the RkISP1 pipeline-handler is done in the subsequent patch.\n\nThe ConverterDW100 class can be extended later (as additional\ndevelopment) to support the dewarping by setting a dewarp vertex\nmap as well.\n\nSigned-off-by: Umang Jain \nReviewed-by: Paul Elder \n---\n .../internal/converter/converter_dw100.h | 24 ++++++++++++\n .../libcamera/internal/converter/meson.build | 1 +\n src/libcamera/converter/converter_dw100.cpp | 37 +++++++++++++++++++\n src/libcamera/converter/meson.build | 1 +\n 4 files changed, 63 insertions(+)\n create mode 100644 include/libcamera/internal/converter/converter_dw100.h\n create mode 100644 src/libcamera/converter/converter_dw100.cpp","diff":"diff --git a/include/libcamera/internal/converter/converter_dw100.h b/include/libcamera/internal/converter/converter_dw100.h\nnew file mode 100644\nindex 00000000..dc41f365\n--- /dev/null\n+++ b/include/libcamera/internal/converter/converter_dw100.h\n@@ -0,0 +1,24 @@\n+/* SPDX-License-Identifier: GPL-2.0-or-later */\n+/*\n+ * Copyright (C) 2024, Ideas On Board Oy\n+ *\n+ * i.MX8MP Dewarp Engine integration\n+ */\n+\n+#pragma once\n+\n+#include \"libcamera/internal/converter/converter_v4l2_m2m.h\"\n+\n+namespace libcamera {\n+\n+class MediaDevice;\n+class Rectangle;\n+class Stream;\n+\n+class ConverterDW100 : public V4L2M2MConverter\n+{\n+public:\n+\tConverterDW100(std::shared_ptr media);\n+};\n+\n+} /* namespace libcamera */\ndiff --git a/include/libcamera/internal/converter/meson.build b/include/libcamera/internal/converter/meson.build\nindex 891e79e7..85007a4b 100644\n--- a/include/libcamera/internal/converter/meson.build\n+++ b/include/libcamera/internal/converter/meson.build\n@@ -1,5 +1,6 @@\n # SPDX-License-Identifier: CC0-1.0\n \n libcamera_internal_headers += files([\n+ 'converter_dw100.h',\n 'converter_v4l2_m2m.h',\n ])\ndiff --git a/src/libcamera/converter/converter_dw100.cpp b/src/libcamera/converter/converter_dw100.cpp\nnew file mode 100644\nindex 00000000..eb9906f0\n--- /dev/null\n+++ b/src/libcamera/converter/converter_dw100.cpp\n@@ -0,0 +1,37 @@\n+/* SPDX-License-Identifier: GPL-2.0-or-later */\n+/*\n+ * Copyright (C) 2024, Ideas On Board Oy\n+ *\n+ * i.MX8MP Dewarp Engine integration\n+ */\n+\n+#include \"libcamera/internal/converter/converter_dw100.h\"\n+\n+#include \n+\n+#include \n+\n+#include \"libcamera/internal/media_device.h\"\n+#include \"libcamera/internal/v4l2_videodevice.h\"\n+\n+namespace libcamera {\n+\n+LOG_DECLARE_CATEGORY(Converter)\n+\n+/**\n+ * \\class libcamera::ConverterDW100\n+ * \\brief The i.MX8MP dewarp converter implements the converter interface based\n+ * on V4L2 M2M device.\n+*/\n+\n+/**\n+ * \\fn ConverterDW100::ConverterDW100\n+ * \\brief Construct a ConverterDW100 instance\n+ * \\param[in] media The media device implementing the converter\n+ */\n+ConverterDW100::ConverterDW100(std::shared_ptr media)\n+\t: V4L2M2MConverter(media.get(), Feature::InputCrop)\n+{\n+}\n+\n+} /* namespace libcamera */\ndiff --git a/src/libcamera/converter/meson.build b/src/libcamera/converter/meson.build\nindex 2aa72fe4..175581b8 100644\n--- a/src/libcamera/converter/meson.build\n+++ b/src/libcamera/converter/meson.build\n@@ -1,5 +1,6 @@\n # SPDX-License-Identifier: CC0-1.0\n \n libcamera_sources += files([\n+ 'converter_dw100.cpp',\n 'converter_v4l2_m2m.cpp'\n ])\n","prefixes":["v6","4/5"]}
