That's fine, may work for your case. Note that in GStreamer, PTS may
start at any point in time. So to be complete, you actually need two
pad probes, one that saves the GstSegment, and then in your BUFFER
probe, you can convert the PTS to stream time using that segment
information. This should work, if it returns TIME_NONE (max uint), it
would mean this buffer is outside the segment, and should be ignored
(like decode only buffers).

cheers,
Nicolas
