gst-plugins-good: matroskamux timestamps

Hi All,

We use gstreamer and matroskamux with application passing buffer and taking
out, here is the pipeline

appsrc name=appsrc block=false is-live=true format=GST_FORMAT_TIME ! queue
name=q !  matroskamux streamable=true ! appsink name=appsink


We pass buffer with PTS -

        GST_BUFFER_PTS(buffer) = timestamp; // in nanos
        GST_BUFFER_DTS(buffer) = GST_CLOCK_TIME_NONE;
        gst_app_src_push_buffer(GST_APP_SRC (m_source), buffer);

we get duplicate PTS on output buffer, though input always has increasing
timestamps, is that possible?
