+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.
+
+Upstream-Status: Backport [from master/0.3.28]
