enables the picture width rounding up: in this case the resolution will be 854x480.
Vertical video aspect ratio calculation
Since build 5.2.1911, WCS detects a stream published orientation by picture width and height and keeps aspect ratio as follows:
1. For horizontal (landscape) video (a picture width is greater than or equal to height) the height
value of transcoding profile will be applied to picture height, a picture width to transcode will be calculated by picture height. For example, a source stream with 1920x1080 (16:9) resolution will be transcoded to 640x360 resolution by profile with height: 360
.
2. For vertical (portrait) video (a picture width is less than height) the height
value of transcoding profile will be applied to picture width, a picture heignht to transcode will be calculated by picture width. For example, a source stream with 1080x1920 (9:16) resolution will be transcoded to 360x640 resolution by profile with height: 360
