[FFmpeg-devel] [PATCH 1/1] ffmpeg: gnutls: ignore TLS rehandshake requests

[Tristan Matthews]

Log a warning instead of terminating.

TLS does not explicitly require that the client initiate the handshake when
requested by the server, it can be ignored (although the server is free to
break the connection if no handshake is forthcoming).
