2016-09-16gen-image: Add conversion from RGB to HSV supportLaurent Pinchart
Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
2016-09-13gen-image: Subsample YUV chroma on inputLaurent Pinchart
When the input format is YUV, subsample the chroma during RGB to YUV conversion based on the YUV format parameters. This matches the RGB to YUV conversion performed to generate the test input frame fed to the RPF. A better fix would be to add support for unpacking all RGB and YUV formats instead of converting the .pnm reference frames. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
2016-09-13gen-image: Add -C argument to disable chroma averaging on outputLaurent Pinchart
gen-image averages consecutive chroma values when subsampling chroma horizontally. This matches the hardware behaviour, but isn't desired to produce test input frames in subsampled formats as otherwise the hardware will average the values a second time in the RPF to interpolate missing chroma components. Add a -C argument to disable chroma averaging on output, to be used to generate test input frames. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
2016-09-13gen-image: Add input format configurationLaurent Pinchart
Replace the -y argument with a more flexible -i argument that allows specifying the input format. This is useful to generate reference frames based on an RGB pipeline input format that uses less than 8 bits per pixel. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
