1. The latest libsrtp release is 2.5 (released 2 months ago), while fedora ships 2.3 (3 years old) 2. Crypto backend in use is NSS which is ~10x slower than the OpenSSL backend when encrypting RTP packets using this benchmark: https://gist.github.com/Sean-Der/7a42bd70edfe1324ccc6ab399d653c0e. On my machine, nss backend takes 12s, built-in crypto lib takes 4.5s, openssl takes 1.6s. 3. Using openssl also allows using hardware cryptography using /dev/crypto 4. Using openssl enables usage of AES-GCM and AES-NI 5. You can also switch from autotools to meson (or cmake) with newer libsrtp
This bug appears to have been reported against 'rawhide' during the Fedora Linux 39 development cycle. Changing version to 39.
