Hello, This patch series adds a color space conversion test to the vsp-tests suite. The aim is to test the "[PATCH 0/6] media: renesas: vsp1: Add colorspace support" series that I have just posted to the linux-media mailing list ([1]). After a small white space cleanup (01/16), the series starts with converting the vsp-tests suit from make to meson, to facilitate cross-compilation. Patch 03/16 is another small cleanup that renames a file to give it the correct extension. The next 6 patches improve the gen-image application to properly handle the color space conversion, implementing a pixel-perfect emulation of the corresponding VSP hardware block. The series then moves on to improving and expanding vsp-lib. Patch 10/16 helped me debug issues by saving RPF input frames upon error for inspection. Patches 11/16 to 14/16 expand the library to support RGB <-> YUV conversion in pipelines. The last two patches add a color space conversion test. Patch 15/16 introduces the new RGB <-> YUV test, without the ability to specify color space parameters, and patch 16/16 then adds the color space parameters. The test requires updates to media-ctl and yavta to support setting colorspace on video capture devices and on subdev source pads. The corresponding patches have been posted to [2] and [3] respectively, I expect them to be merged soon.
