 Summary of the bug:

 When live streaming (HLS) with a persistent HTTP connection, if the web
 server closes the connection ffmpeg shuts down.

 How to reproduce:

 For example, when streaming to an Apache web server (2.4.29/Ubuntu) with
 "!KeepAlive On" and "!MaxKeepAliveRequests 10" ffmpeg will fail on the
 11th PUT request when Apache closes the TCP connection.
