--- Comment #1 from Vincent Penquerc'h <vincent.penquerch at collabora.co.uk> ---
I found a sample which reproduces that, and the bug comes from filler data
being marked for dropping by h264parse then dropped by baseparse, which returns
GST_FLOW_OK since it doesn't actually push anything, thereby overriding the
flow result ultimately returned.

It's not quite clear how that should be fixed. The obvious way would be to keep
a "last_ret" field in baseparse, and return this when dropping or otherwise not
pushing, instead of OK.
