In listen mode with UDP transport, once the sender has sent the TEARDOWN and closed the connection, poll will indicate that one can read from the connection (indicating that the socket has reached EOF and should be closed by the receiver as well). In this case, parse_rtsp_message won't try to parse the command (because it's no longer in state STREAMING), but previously just returned zero. Prior to f6161fccf8c5720ceac1ed1df8ba60ff8fed69f5, this caused udp_read_packet to return zero, which is treated as EOF by read_packet. But after that commit, udp_read_packet would continue if parse_rtsp_message didn't return an explicit error code. To keep the original behaviour from before that commit, more explicitly return an error in parse_rtsp_message when in the wrong state. Fixes: #8840 Signed-off-by: Martin Storsjö <martin@martin.st>
