videorate: Make it possible to only duplicate frames
Submitted by Joe Palmer
Link to original bug (#774099)
Description
Currently there is a option for frames to drop-only. We have a requirement to only duplicate frames where there are gaps and never to drop any. With the current set of options, we cannot find a configuration that results in duplicated frames only without any being dropped. It would therefore seem sensible to add an duplicate-only option to compliment drop-only.
