[gst-devel] gst-xmllaunch not working on file created from gst-launch

Here I make a simplest case using Ubuntu, which works for gst-launch, but does not work for gst-xmllaunch:

gst-launch playbin uri="file:///home/nfan/Videos/001.mpg"

This works well, but then try:

1) gst-launch -o test.xml playbin uri="file:///home/nfan/Videos/001.mpg" (result: save of file works)
2) gst-xmllaunch test.xml

Result output of #2 is:

Setting pipeline to PAUSED ...
gst_mpegts_demux_base_init
Pipeline is PREROLLING ...
WARNING: from element /GstPlayBin:playbin0: Invalid subtitle URI "", subtitles disabled.
0:00:00.088855368  2372  0x902b598 ERROR                 ffmpeg :0:: warning: first frame is no keyframe

The execution paused without return, unless issuing a ctrl-C.

Is there something I'm missing with gst-xmllaunch or steps prior to this?
