Hi Philippe,

Thank you for your suggestions. I chose to connect to the "element-added"
signal for further manipulation on the element added to decodebin.

With regard to gst_bin_get_by_interface(), I do not know how to set the
interface. I saw GST_TYPE_URI_HANDLER for filesrc and GST_TYPE_TAG_SETTER
for muxer. What interfaces should be used to look for video decoder, video
decoder, and parser inside decodebin? 

Thanks
