What is xvimagesink?

[jiapei100]

Hi, all:

Sorry for my naive question. I finally have my IP camera successfully viewed by the following "gstreamer" command.

gst-launch -v souphttpsrc location='http://192.168.1.81:80/videostream.cgi?rate=15&user=aaaaa&pwd=bbbbb' do-timestamp=true timeout=5 ! multipartdemux ! image/jpeg,width=640,height=480,framerate=15/1 ! jpegdec ! xvimagesink

Without the last parameter "xvimagesink", the command

gst-launch -v souphttpsrc location='http://192.168.1.81:80/videostream.cgi?rate=15&user=aaaaa&pwd=bbbbb' do-timestamp=true timeout=5 ! multipartdemux ! image/jpeg,width=640,height=480,framerate=15/1 ! jpegdec

always complains

ERROR: from element /GstPipeline:pipeline0/GstSoupHTTPSrc:souphttpsrc0: Internal data flow error.

1) Can anybody help to explain what is "Xv based videosink" as described http://gstreamer.freedesktop.org/data/doc/gstreamer/head/gst-plugins-base-plugins/html/gst-plugins-base-plugins-xvimagesink.html

2) Can anybody help to explain what is the Error message telling?

Thank you very much...

Best Regards

xvimagesink is a Sink which is responsible for handling the
videodata. The xvimagesink opens the XWindow and shows your video data.

Without xvimagesink in your gstreamer pipeline, you would need
another think (filesink for example) which takes your videodata.
Without any sink the data can not flow through your pipeline.
Thats the errormessage "internal dataflow error"
