Image::crop_scale_window would do the wrong thing if we then applied a crop of greater than 128 in either direction; though cropped_size is correctly clamped, the crop value itself was not and is used to calculate the input data pointers. This would result in random frames, usually at the end of DCPs, often made up of blurry colour washes. Fix cropping of subsampled images. 2020-11-16T23:16:58Z Carl Hetherington cth@carlh.net 2020-11-16T23:00:50Z urn:sha1:17959746895a04bd20cc20cd8bdde91d71570b53 The calculations for how to crop subsampled components of YUV images were wrong, causing strange effects like misregistration of colour components in cropped images. Should fix #1872. Add some lrintf() calls to be sure. 2020-11-16T23:16:58Z Carl Hetherington cth@carlh.net 2020-11-16T22:58:53Z urn:sha1:40339285d62d136c4f87c8c7e030ff4f2bdb55b9 Use 64-byte alignment for aligned image memory. 2020-11-16T23:16:58Z Carl Hetherington cth@carlh.net 2020-11-16T22:56:11Z urn:sha1:fcc0515087a0b2bf9af5043af1c324367f1c152c FFmpeg uses this values if AVX512 is available, and with only 32-byte alignment I am seeing strange scaling effects whereby crop_scale_window_test7 gives black bars down the right side of cropped images (when run on an i7 7700). Make sure we use limited ("video") range data when exporting. 2020-11-16T00:40:36Z Carl Hetherington cth@carlh.net 2020-11-15T19:47:42Z urn:sha1:b057363e69b77119137c0c8b07402828096e03aa Our export formats all currently use limited range but we weren't making sure data fed to the encoders was limited range. Should fix #1832. Remove pointless comment. 2020-11-16T00:40:36Z Carl Hetherington cth@carlh.net 2020-11-08T21:37:34Z urn:sha1:0a599a0f32da02358d1caac11e7c61a2d5bd0aa0
