Picture width alignment while preserving a picture aspect ratio
Since build 5.2.1842 it is possible to set a picture width alignment when aspect ratio preserving is enabled. By default, a picture width will be rounded down:
| Code Block | ||
|---|---|---|
| ||
video_transcoder_round_ratio=0 |

| Code Block | ||
|---|---|---|
| ||
video_transcoder_round_ratio=1 |
enables the picture width rounding up: in this case the resolution will be 854x480.
