           Summary: avidemux does not reset its state properly on PAUSED-
                    >READY
           Product: GStreamer
           Version: HEAD CVS
          Platform: Other
        OS/Version: All
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal

Please describe the problem:
gstavidemux.c:gst_avi_demux_reset () does not set several member of GstAviDemux
structure.
in particular it needs
 avi->header_state = GST_AVI_DEMUX_HEADER_TAG_LIST;

Also gst_avi_demux_parse_stream () removes existing pads an replaces
them with new ones for reasons unclear. New pads end up being unlinked.

Steps to reproduce:
1. Build test program:
gcc -o pipelineplayer `pkg-config --cflags-only-I gstreamer-0.10`
pipelineplayer.c `pkg-config --libs gstreamer-0.10`
2. Run the program:
./pipelineplayer 'videotestsrc ! ffmpegcolorspace ! timeoverlay ! ffenc_mpeg4 !
avimux ! avidemux ! ffdec_mpeg4 ! ffmpegcolorspace ! ximagesink'
It outputs the pid of its program, and an X11 client window appears.
3. Send HUP signal
kill -HUP <pid>

Actual results:
The X11 client window disappears

Expected results:
The window should stay and timestamps should restart

Does this happen every time?
yes

Other information:
works for the following pipeline:
/pipelineplayer 'videotestsrc ! ffmpegcolorspace ! timeoverlay ! ffenc_mpeg4 !
ffdec_mpeg4 ! ffmpegcolorspace ! ximagesink'
