"Buffer has no PTS" with this H264 IP Camera

>> In my experience, qtmux reports "buffer has no PTS" if two consecutive buffers have the same timestamp. This can occur if h264parse receives a frame with invalid timestamp e.g. CLOCK_TIME_NONE it then guesses a timestamp. You could insert a pad-probe which checks the timestamps before h264parse and checks that the timestamp is plausible.

This bug could be related

https://bugzilla.gnome.org/show_bug.cgi?id=788777

if your issue does not happen in gstreamer 1.10.2 and lower is the same
