But this is still\nwork in progress hence the [RFC] for the last two patches.\n\nChanges in v2 vs v1:\n- added a separate patch to fix the ConverterFactoryBase documentation\n- modified the Converter class to make the '*media' parameter optional\n instead of splitting out ConverterMD from the Converter. This\n also makes it possible to use the same ConverterFactory template\n for converters that rely on MediaDevice, and the software ones.\n- removed the unnecessary header includes\n\n[1] https://patchwork.libcamera.org/cover/18924/\n\nAndrey Konovalov (4):\n libcamera: converter: a few fixes to ConverterFactoryBase\n documentation\n libcamera: converter: make using MediaDevice optional for the\n Converter\n libcamera: converter: add software converter\n libcamera: pipeline: simple: enable software converter for qcom-camss\n\n include/libcamera/internal/converter.h | 9 +-\n .../internal/converter/converter_softw.h | 90 ++++\n .../libcamera/internal/converter/meson.build | 1 +\n src/libcamera/converter.cpp | 66 +--\n src/libcamera/converter/converter_softw.cpp | 410 ++++++++++++++++++\n src/libcamera/converter/meson.build | 3 +-\n src/libcamera/pipeline/simple/simple.cpp | 35 +-\n 7 files changed, 572 insertions(+), 42 deletions(-)\n create mode 100644 include/libcamera/internal/converter/converter_softw.h\n create mode 100644 src/libcamera/converter/converter_softw.cpp" }
