Currently, this is broken for thumbnail\nencoding as the thumbnail generated is directly passed as a single\nplane.\n\nHence, piece the thumbnail data as planes if the parent Framebuffer is\nmulti-planar. This fixes the encoding of the corresponding thumbnail.\n\nFixes: 894ca69f6043(\"android: jpeg: Support multi-planar buffers\")\nSigned-off-by: Umang Jain <umang.jain@ideasonboard.com>\n---\n src/android/jpeg/post_processor_jpeg.cpp | 17 +++++++++++------\n 1 file changed, 11 insertions(+), 6 deletions(-)", "diff": "diff --git a/src/android/jpeg/post_processor_jpeg.cpp b/src/android/jpeg/post_processor_jpeg.cpp\nindex 68d74842..d896581f 100644\n--- a/src/android/jpeg/post_processor_jpeg.cpp\n+++ b/src/android/jpeg/post_processor_jpeg.cpp\n@@ -66,13 +66,18 @@ void PostProcessorJpeg::generateThumbnail(const FrameBuffer &source,\n \tint ret = thumbnailEncoder_.configure(thCfg);\n \n \tif (!rawThumbnail.empty() && !ret) {\n-\t\t/*\n-\t\t * \\todo Avoid value-initialization of all elements of the\n-\t\t * vector.\n-\t\t */\n-\t\tthumbnail->resize(rawThumbnail.size());\n+\t\tstd::vector<Span<uint8_t>> thumbnailPlanes;\n+\t\tfor (int i = 0; i < source.planes().size(); i++) {\n+\t\t\tunsigned int thumbnailSize =\n+\t\t\t\ttargetSize.height * targetSize.width;\n+\t\t\tSpan<uint8_t> plane{\n+\t\t\t\trawThumbnail.data() + (i * thumbnailSize),\n+\t\t\t\tthumbnailSize\n+\t\t\t};\n+\t\t\tthumbnailPlanes.push_back(plane);\n+\t\t}\n \n-\t\tint jpeg_size = thumbnailEncoder_.encode({ rawThumbnail },\n+\t\tint jpeg_size = thumbnailEncoder_.encode(thumbnailPlanes,\n \t\t\t\t\t\t\t *thumbnail, {}, quality);\n \t\tthumbnail->resize(jpeg_size);\n \n", "prefixes": [ "libcamera-devel" ] }
