Comment:

 I was having the same issue.   RTSP has its own timeout handling, not sure
 how it interacts with rw_timeout.  I "fixed" my RTSP by modifying the
 define:

 /* Timeout values for socket poll, in ms,
  * and read_packet(), in seconds  */
 #define POLL_TIMEOUT_MS 100
 #define READ_PACKET_TIMEOUT_S 10
 #define MAX_TIMEOUTS READ_PACKET_TIMEOUT_S * 1000 / POLL_TIMEOUT_MS


 The math in the code is off somehow since the timeout is actually 2 times
 the READ_PACKET_TIMEOUT_S.  I didn't dig any further.
