Reset timestamp mpegtsmux

[Angel Martin]

Dear all,

I am developing a RTP server over OSSBuild (Gstreamer 0.10 Windows)

The stream hosts a H.264+TS video created from a appsrc with a multiudpsink.

I have a tee to generate 2 paths, 1 mpegtsmux for streaming and 1
mp4mux for local file storage.

I would like to restart mpegtsmux timestamps everytime I change mp4mux
destination file to get coherent timestamps. The different mp4 files
have a reseted timestamp starting from 0 in the VLC (ok for my
purposes) because I: block the pad; move to NULL state mp4mux and
filesink; unlink them; create new ones; link again; and move to state
PLAYING. I suppose that I can not do the same for the streaming bin
because I would disconnect VLC remote players.

In someway is the same scenario explained here:
http://gstreamer-devel.966125.n4.nabble.com/Resetting-base-time-in-part-of-running-pipeline-td970032.html
But I do not have the elements "shift" or "stamp" in the 0.10. In
version 1.0 gst_pad_set_offset fixes it. But I'd like to now if there
is a solution for that in 0.10 to reset timestamps.
A possibility is to include the custom resettime element.

I have explored the following possibilities:

1) Move the pipeline to READY

2) new_segment for the pipeline element

3) new_segment for the appsrc pad

4) new_segment for the caps_src before the mpegtsmux

5) new_segment for the mpegtsmux sink

6) switch "do-timestamp" of appsrc to "false" and set myself the time
buffer (http://cgit.freedesktop.org/gstreamer/gst-plugins-base/tree/gst/videotestsrc/gstvideotestsrc.c?h=0.10)
  GST_BUFFER_TIMESTAMP (outbuf) = src->timestamp_offset + src->running_time;
  GST_BUFFER_OFFSET (outbuf) = src->n_frames;
  src->n_frames++;
  GST_BUFFER_OFFSET_END (outbuf) = src->n_frames;
  if (src->rate_numerator) {
    next_time = gst_util_uint64_scale_int (src->n_frames * GST_SECOND,
        src->rate_denominator, src->rate_numerator);
    GST_BUFFER_DURATION (outbuf) = next_time - src->running_time;
  } else {
    next_time = src->timestamp_offset;
    /* NONE means forever */
    GST_BUFFER_DURATION (outbuf) = GST_CLOCK_TIME_NONE;
  }
 checking right timestamps with:
g_printerr("timestamp %" GST_TIME_FORMAT "\n",
GST_TIME_ARGS(GST_BUFFER_TIMESTAMP (buf)));
(http://gstreamer-devel.966125.n4.nabble.com/Trying-to-reset-the-pipeline-whithout-closing-it-td3814702.html)
However mpegtsmux seems to use running-time instead of taking the
stream-time from the buffers.

Any tip or idea?
