 Summary of the bug:
 When built with OpenSSL, FFmpeg is unable to negotiate a TLSv1.2 session
 with servers that use certain cipher suites. I haven’t narrowed it down to
 anything in particular, but 0x0.st uses ECDHE with ECDSA rather than RSA.

 Other software that uses OpenSSL works fine.

 How to reproduce:
