exact=1 crop filter for nv12-format video seems to swap color components (when specifying odd crop coordinates)

[nijikilling]

Summary of the bug: when crop filtering any video in nv12 format with exact=1, it works good for even (x, y), but for odd (x, y) the resulting video has strong color mismatch as if two color components were swapped in process.

How to reproduce: decode video using h264_cuvid, in video filter specify "hwdownload,format=nv12,crop=...:x=(even):y=(even):exact=1".

In the report below, video ​https://sample-videos.com/video123/mp4/720/big_buck_bunny_720p_10mb.mp4 was used, but it seems to happen on every video I checked.
