The only real restriction at vim2m is that width should be multiple of two, as the copy routine always copy two pixels each time. However, Bayer formats are defined as having a 2x2 matrix. So, odd vertical numbers would cause color distortions at the last line. So, it makes sense to use step 2 for vertical alignment on Bayer. With this patch, the reported formats for video capture will be: [0]: 'RGBP' (16-bit RGB 5-6-5) Size: Stepwise 32x32 - 640x480 with step 2/1 [1]: 'RGBR' (16-bit RGB 5-6-5 BE) Size: Stepwise 32x32 - 640x480 with step 2/1 [2]: 'RGB3' (24-bit RGB 8-8-8) Size: Stepwise 32x32 - 640x480 with step 2/1 [3]: 'BGR3' (24-bit BGR 8-8-8) Size: Stepwise 32x32 - 640x480 with step 2/1 [4]: 'YUYV' (YUYV 4:2:2) Size: Stepwise 32x32 - 640x480 with step 2/1 [5]: 'BA81' (8-bit Bayer BGBG/GRGR) Size: Stepwise 32x32 - 640x480 with step 2/2 [6]: 'GBRG' (8-bit Bayer GBGB/RGRG) Size: Stepwise 32x32 - 640x480 with step 2/2 [7]: 'GRBG' (8-bit Bayer GRGR/BGBG) Size: Stepwise 32x32 - 640x480 with step 2/2 [8]: 'RGGB' (8-bit Bayer RGRG/GBGB) Size: Stepwise 32x32 - 640x480 with step 2/2 Signed-off-by: Mauro Carvalho Chehab <mchehab+samsung@kernel.org> |
