This should be fixed in this version.\n\nI came to realize that stride support was broken in qcam when testing\n[1] on Raspberry Pi with the YUV420 format. This patch series fixes it\nfor all RGB and YUV formats, and also adds YUV420 support to the\nsoftware converter.\n\nThe patches apply on top of [1]. I've tested ARGB8888, YUYV, NV12 and\nYUV420, with both viewfinders. Only YUV420 had padding at the end of\nlines, so other formats may not work properly when padding is present,\nbut there should at least be no regression.\n\n[1] https://lists.libcamera.org/pipermail/libcamera-devel/2021-September/024477.html\n\nLaurent Pinchart (5):\n qcam: viewfinder: Pass stride value to viewfinder\n qcam: format_converter: Add configurable stride support\n qcam: format_converter: Rename YUV and NV to YUVPacked and\n YUVSemiPlanar\n qcam: format_converter: Add fully-planar YUV formats support\n qcam: viewfinder_gl: Support configurable stride in shaders\n\n src/qcam/assets/shader/identity.vert | 4 +-\n src/qcam/format_converter.cpp | 187 ++++++++++++++++++---------\n src/qcam/format_converter.h | 14 +-\n src/qcam/main_window.cpp | 3 +-\n src/qcam/viewfinder.h | 3 +-\n src/qcam/viewfinder_gl.cpp | 61 ++++++---\n src/qcam/viewfinder_gl.h | 4 +-\n src/qcam/viewfinder_qt.cpp | 4 +-\n src/qcam/viewfinder_qt.h | 3 +-\n 9 files changed, 195 insertions(+), 88 deletions(-)" }
