Example code for sending extra data along with GstBuffer

[salahgafoor]

Hi,

I have created a gstreamer plugin, I have to send some arbitrary data from my plugin to the succeeding element (which is also created by myself) in addition to the GstBuffer data.

I have referred following links, but I failed in implementing this functionality.
Link1

Link2

Please provide some example code or links which would suite me.
Thanks in advance!

If data has to be sent along with the buffer then Metadata is better option.

You need to write small piece of code to insert and retrieve the metadata.

Note: Elements in pipeline should pass through the metadata
