Deinterlace element and "fields=bottom" causes framerate to disappear (0/1)

[Graham Leggett]

Hi all,

I have the deinterlace element within a pipeline, and have noticed that when "fields=bottom” is added to the deinterlace element the framerate of the rest of the pipeline disappears and becomes 0/1.

Take the "fields=bottom” out again, and the framerate returns to 25/1.

Is this a bug or expected behaviour?

Regards,
Graham
