Similar to lib32-librtmp0, it looks like librtmp0 is lagging behind the Nettle crypto lib. We could patch the source before building:

prepare() {
  cd rtmpdump
  # Switch to GnuTLS
  sed -e 's/^CRYPTO=OPENSSL/#CRYPTO=OPENSSL/' -e 's/#CRYPTO=GNUTLS/CRYPTO=GNUTLS/' -i Makefile -i librtmp/Makefile

  # Fix Nettle 3.x API mismatch (removes the extra length argument in hmac_sha256_digest)
  sed -i 's/hmac_sha256_digest(&ctx, SHA256_DIGEST_LENGTH, dig)/hmac_sha256_digest(\&ctx, dig)/' librtmp/handshake.h
}

it's failing to build
