This breaks compilation with OpenSSL 1.1.1t:

src/libavformat/tls_openssl.c:1019:22: error: no member named 'dtls_eckey' 
in 'struct TLSContext'
  1019 |     EC_KEY_free(ctx->dtls_eckey);
       |                 ~~~  ^

So this change does require some configure checks or source level version 
checks to see if we have a new enough version of OpenSSL to do what this 
does.

probably time to upgrade openssl, too.

Sep 13, 2023 The OpenSSL Project has ended the long-term support for version 1.1.1

Sry about that, I’ve fix this issue in latest patch.
We support openssl versions > 1.0.1k, you can find it in configure checks, I’ll check other openssl versions if works well.

Thanks for your reminder!
