Be that as it may, it still looks like the problem is in hantromp4mux:

gstpad.c:4937:gst_pad_send_event:<mp4mux0:src> have event type latency
gstpad.c:3430:gst_pad_event_default:<mp4mux0:src> default event handler
gstpad.c:3335:gst_pad_event_default_dispatch:<mp4mux0:src> Sending event
0xac860 (latency) to all internally linked pads
gstpad.c:3131:gst_pad_iterate_internal_links_default:<mp4mux0:src> Making
iterator
gstpad.c:3366:gst_pad_event_default_dispatch:<mp4mux0:src> sending event
0xac860 (latency) to one sink pad mp4mux0:audio
gstpad.c:4760:gst_pad_push_event:<mp4mux0:audio> event: latency
gstpad.c:4834:gst_pad_push_event:<mp4mux0:audio> Dropping event because pad is
not linked
gstpad.c:4965:gst_pad_send_event:<mp4mux0:src> sent event, result 0
gstpad.c:4820:gst_pad_push_event:<filesink0:sink> sent event to peerpad
<mp4mux0:src>, result 0

So it tries to forward the event on the unlinked audio pad, and that fails and
so it returns FALSE. So something either needs to accumulate properly and/or
forward the event properly. Or it should use request pads so there aren't input
pads that aren't used hanging around. (And btw, it also should register itself
with GType "GstMp4Mux" btw).



@xiaohui: as Stefan said, it's only a warning, you can ignore it. If it bothers
you, you can feed some audio into hantromp4mux (e.g. ... ! hantromp4mux
name=mux ! filesink location=foo.mp4  audiotestsrc ! audioconvert ! nokiaaacenc
! mux. ), then it will go away.
