This has been validated\nby studying the internal conversions made by libyuv for different\nframe generators.\n\nFor MJPEGToNV12: libyuv validates for sYCC colorspace using JPEG header\ninfo\n\nFor ARGB<>NV12: libyuv operates with BT.601 colorspace (ycbcr encoding\nand range is altered).\n\nThe tricky part is to select color primaries for TestPatterns frame\ngenerators. I have used ColorSpace::Primaries::Rec709 as it is widely\nused/assumed in RGB domain. I don't have answer to why we still can't\nuse the SMPTE color primary for those.\n\nUmang Jain (3):\n  pipeline: virtual: image_frame_generator: Explicitly include libcamera\n    headers\n  pipeline: virtual: Implement colorspace() getter for frame generators\n  pipeline: virtual: Rectify validation of colorspace\n\n .../pipeline/virtual/frame_generator.h         |  3 +++\n .../pipeline/virtual/image_frame_generator.cpp |  9 +++++++++\n .../pipeline/virtual/image_frame_generator.h   |  5 +++++\n .../virtual/test_pattern_generator.cpp         | 18 ++++++++++++++++++\n .../pipeline/virtual/test_pattern_generator.h  |  4 ++++\n src/libcamera/pipeline/virtual/virtual.cpp     |  8 ++++----\n 6 files changed, 43 insertions(+), 4 deletions(-)"
