Description Daniel F 2018-04-13 09:01:52 UTC 
I see this in logs repeatedly when DTLS handshake is performed:

0:00:00.404539920 19083      0x130ead0 WARN          dtlsconnection gstdtlsconnection.c:737:openssl_poll:<GstDtlsConnection@0x137dde0> do_handshake encountered BIO error

Here are additional details:
SSL_do_handshake() returned -1
SSL_get_error() returned 5 (SSL_ERROR_SYSCALL)
errno is 0 (Success)
ERR_error_string() returned "error:00000005:lib(0):func(0):DH lib"

Real sockets do not return EOF when there is no data available. Your custom BIO does this when buffer is empty. I suspect that it should not do this, to match way how sockets operate:

Do you want to make a patch for this?
