Description Matej Knopp 2013-07-14 11:48:01 UTC 
When there is no framerate in caps gstdeinterlace seems to be outputting same timestamps on duplicate frames, i.e.

Input:
frame with PTS 10
frame with PTS 20
frame with PTS 30

Output:
frame with PTS 10
frame with PTS 10
frame with PTS 20
frame with PTS 20
frame with PTS 30
frame with PTS 30
Comment 1 Sebastian Dröge (slomo) 2013-07-15 06:04:44 UTC 
It probably should wait for the next frame then and use its timestamp as the duration. Not that urgent though, in interlaced streams you are supposed to have a framerate usually.
Comment 2 Matej Knopp 2013-07-15 08:31:09 UTC 
Well, for now I just don't add the filter if framerate is missing/variable. But it's not very nice, I think it should be able to handle the situation more gracefully, even if just doing passthrough.
