[Live-devel] windows winsock error 10038

[Andrey]

Hi, Ross. I was able to simulate error WINSOCK 10038. To do this, RTSP 
client must ask the server to send the stream. Accordingly, you should 
set REQUEST_STREAMING_OVER_TCP to True. Then you need to properly shut 
down the client, without sending the command TEARDOWN. Maybe a few 
times. And the next time the client connects, the server returns an 
error when you call select(). The error occurs on the client socket and 
the socket until it actually closes, but then again entered into the 
table socket, then an error occurs. After that there is only a few 
iterations SingleStep(), and then the handler of this problem socket is 
removed from the table and error in the select() no longer occurs. I 
would also like to draw attention to some of the code for the withdrawal 
of additional debugging information in the SingleStep(). In lines
..........
fprintf(stderr, "socket numbers used in the select() call:");
     for (int i = 0; i < 100; ++i) {
..........
i less than a hundred, but the windows usually have handles more than 
100 sets, so it's best to put 10000.


This is my log:

(We use port 80 for optional RTSP-over-HTTP tunneling.)
