            Bug ID: 788827
           Summary: mxfmux : Mxfmux is not functional with splitmuxsink
    Classification: Platform
           Product: GStreamer
           Version: 1.12.1
                OS: Linux
            Status: NEW
          Severity: major
          Priority: Normal
         Component: gst-plugins-bad
          Assignee: gstreamer-bugs at lists.freedesktop.org
          Reporter: jagadishkamathk at gmail.com
        QA Contact: gstreamer-bugs at lists.freedesktop.org
     GNOME version: ---

There are two issues
1. Pad templates of mxfmux is not generic like that of mp4. Splitmuxsink does't
have support for such pad templates(ex: mpeg_audio_sink_%u). Its good to have
generic pad template such as audio_%d, video_%d etc
2. With workaround for above issue(hardcoding in splitmuxsink), I tried to run
a pipeline to fragment filed and mux them into MXF. Issue happens during the
creation of second fragment. EOS isn't handled properly I guess which is
leading to crash. 

Here is the pipeline
gst-launch-1.0 videotestsrc is-live=1 ! video/x-raw,format=I420 ! x264enc !
splitmuxsink muxer=mxfmux location=/root/out_%d.mxf max-size-time=4000000000

ERROR:mxfmux.c:1571:gst_mxf_mux_handle_eos: assertion failed: (mux->offset ==
body_partition)
