+Subject: PipeWire capturer: fix fcntl call when duplicating a file descriptor
+
+The fcntl() call has variable arguments, therefore we need to pass 0 to
+specify there are no other arguments for this call, otherwise we might
+end up with an argument that is random garbage.

+Subject: PipeWire capturer: increase buffer size to avoid buffer overflow
+
+Recently added framerate option can cause a buffer overflow and make
+PipeWire to fail on negotiation, which effectively makes screen sharing
+not to work.
