title: Gstreamer for Android Buffer has no PTS
body: <p>I created the pipeline <code>gst_parse_launch(&quot;rtspsrc location=rtsp://192.168.0.77:554/user=admin_password_=tlJwpbo6_channel=1_stream=0.sdp?real_stream ! queue !rtph264depay ! h264parse !  splitmuxsink muxer=\&quot;mp4mux name=muxer\&quot; max-size-bytes=20000000  location=/storage/emulated/0/DVR/CameraX/the_file_%d.mp4&quot;,NULL);</code>  and it works fine with Gstreamer version 1.9.1. I want to use newer versions for some other reasons but with above versions 1.10.X and 1.11.X pipeline stops after working for some indeterminate time between seconds to minutes. Logcat output is here:</p>

  <p>I tried for different camera models. I removed splitmuxsink and tried with mp4mux but result did not change. I changed &quot;presentation-time&quot; property of mp4mux but nothing changes.</p>
