How to transfer GstBuffer from one pipeline to other pipeline

[Anton Pryima]

Hello Shiva.

In the appsink callback, you're not own reference for GstBuffer. You need
to perform gst_sample_copy/gst_buffer_copy_deep on the receiver side to get
a new object, before pushing it to appsrc. Do not forget to unref it after
using.

Best regards,
Anton.
