+Subject: pipewiresink: use all the available dest memory when copying buffer
+
+When pipewiresink needs to copy data, it has to resize the destination
+buffer (to a smaller size) in order to send the correct data size to
+pipewire. When this dest buffer is reused later, it will still have
+this smaller size as its total size and the copy may discard data
+from upstream if the new upstream buffer is bigger than the last one
+that was copied on the same dest buffer.

+Subject: pipewiresink: release manually acquired buffers back to the pool
+
+When we manually acquire buffers from the pool, we never release them.
+But because gst_buffer_pool_acquire_buffer() adds a reference to the pool,
+this leaks the pool eventually.
+
+To fix this, just unref the buffer after it has been sent. This releases
+it back to the pool and unrefs the pool.
+
+This has no significant effect to the stream, since the underlying
+pw buffers are actually pooled in the pw_stream. It just prevents leaking.
