Then it means, I can't set this property through gst-launch,
but create the element and set it to playbin in programming language (C,
python, etc.).
This is correct.

Thanks.

GST_TYPE_ELEMENT， that means the video-sink is a GstElement, actually
it should be a GstElement pointer and the default value is NULL.
You need to create the videosink element externally, and set the pointer
to this property. You can refer totem sourcecode.

video-sink is GstElement? But I saw the following codes:
gst_play_bin_class_init (GstPlayBinClass * klass)
{
...
g_object_class_install_property (gobject_klass, ARG_VIDEO_SINK,
g_param_spec_object (video-sink, Video Sink,
the video output element to use (NULL = default sink),
GST_TYPE_ELEMENT, G_PARAM_READWRITE));
...
}

The type of Video-sink is GstElement, not string.

My gst version is 0.10.18 (Ubuntu hardy).
I saw that playbin has the property of video-sink, but my try
fails:
gst-launch playbin -v -v
uri=file:///home/halley/media/video/test.avi
video-sink=xvimagesink
The error message is:
WARNING: erroneous pipeline: could not set property video-sink
in
element playbin10 to xvimagesink
Even when I try to use playbin2 and fakesink, it always give the
same
error.
Where is my problem, thanks.

Hi Mke,
Thank you.
So the only way is to use playbin2? what is the difference on
intefaces,
properties and signals between playbin2 and playbin?
I find most of them are same.
The only sensible approach (assuming you want to reuse existing
code,
rather than writing something from scratch yourself) is to switch
to
playbin2.
The documentation can help you with the differences - you're
right,
most things are similar.
