[Libav-user] av_interleaved_write_frame doesn't detect failure for TLS output

Dan Allen
I use libavformat to mux H.264 frames and send them out using RTSPS ANNOUNCE over TLS.  When the output is not encrypted and the server becomes unavailable, av_interleaved_write_frame returns an error which allows me to retry the connection (av_interleaved_write_frame failed result=-32 - Broken pipe).

When the output is TLS, av_interleaved_write_frame continues to return success even when the server is unavailable so the application doesn't know to retry (av_interleaved_write_frame st.tb=90000, result=0).

Is there another way I can determine with libavformat that the TLS connection is no longer valid?

FFmpeg version 3.2 + RTSPS patch

This behaviour can also be reproduced with the command line tools (older version that has RTSPS support).
