Commit ad2c7bffe7d94c79184904b14101cbc93eeb9ebd breaks the unit tests.
If I interpret the problem correctly, the old logic sent a newsegment, and then
flushed any data in the adapter (presumably because it comes from the old
segment).
The new logic flushes the adapter whenever there is a pending newsegment event,
but doesn't send the newsegment until there is a complete frame. This leaves it
in a state where until there is a single input buffer containing a full frame,
the parser continuously flushes the adapter (containing part of a frame), and
never pushes the newsegment event.
See gstbaseparse.c:886 for the offending gst_adapter_clear() code.
I would guess that the fix is to move the gst_adapter_clear() to a better
location, possibly when the pending newsegment event is enqueued in the first
place - as presumably any data after then comes from the new segment and needs
to be separated from the old, incomplete, frames.
