[gst-devel] downstream allocated buffers

[Thirupathiah Annapureddy]

Hi All,
How can a downstream element can enforce the upstream peer to use its
own buffers. For example, in the following pipeline
filesrc -> custom decoder -> file sink
I want the file src to read the data into the buffers allocated by the
custom decoder. custom decoder allocates mmaped dmable buffers from
the driver. This technique can reduce the memory copy overhead. how
can we ensure that the filesrc always reads the data into the buffers
allocated by the custom decoder?

Thanks in advance,
A. Thirupathi Reddy.
