How to use splitmuxsink with multiple pipelines?

[pisymbol .]

Here is what I was using:




matroskamux name=muxer streamable=true ! multifilesink name=mfsink post-messages=true next-file=5 max-file-duration=\"{}\" location=\"{}\"

.. ! h264parse ! queue ! muxer.video_0

.. ! h264parse ! queue ! muxer.video_1




Which works fine. But If I translate this to splitmuxsink, gst-launch complains that it can't connect queue to muxer:




splitmuxsink name=muxer send-keyframe-requests=10000000000 muxer=matroskamux muxer-properties="properties,streamable=true" max-size-time=\"{}\" location=\"{}\"

.. ! h264parse ! queue ! muxer.video_0

.. ! h264parse ! queue ! muxer.video_1




I've Googled extensively but I can't find an example of using splitmuxsink with two different pipelines (this thread came the closest: http://gstreamer-devel.966125.n4.nabble.com/record-H264-stream-use-multifilesink-td4684985.html)

After looking at some debug output and then gst-inspect-1.0:

Pad Templates:
  SINK template: 'video'
    Availability: On request
      Has request_new_pad() function: gst_splitmux_sink_request_new_pad
    Capabilities:
      ANY

  SINK template: 'audio_%u'
    Availability: On request
      Has request_new_pad() function: gst_splitmux_sink_request_new_pad
    Capabilities:
      ANY

Only one video stream, huh? Bummer

splitmuxsink in git master supports multiple video streams. The pad for
the main stream (which will be used to determine where things get
split) is called "video" and the ones for the other video streams is
called "video_aux_0" etc. then.

Am I dreaming ?

splitmuxsink template:
    SINK template: 'video'
    Availability: On request
    Capabilities:
      ANY

Only 1 video stream allowed !?!

sorry about that,
Nicolas

I think Tim's answer solves the mystery! Unfortunately, that is a non-starter given the platform (Jetson).

Thanks Tim! Much appreciated. Give me a little credit for researching it (I didn't dive into the code on master though).
