Question about usage of `videorate` plugin

[David Ing]

I want a gstreamer element that will limit the maximum frame-rate of a video stream to 25 fps.  The frame-rate can dip below 25 fps, but it should not go above that.

Can I use the videorate plugin, as follows?

• max-rate = 25
• drop-only = true

If not, what approach can I take to accomplish this?

It's more usual to have a caps filter for the framerate.

• drop-only = true

Drop only does what you want. Lower framerate should not cause duplicates.

If not, what approach can I take to accomplish this?

It's more usual to have a caps filter for the framerate.

The reason I don't want a caps filter is because I don't want the frame-rate to be increased when it is below 25 fps.

videorate is the plugin to use for what you are describing

If you use drop-only it will never be increased. I am not certain what purpose is for this new max-rate, but it's likely niche.
