title: ffmpeg Live Streaming Error : av_interleaved_write_frame(): Broken pipe
body: <p>I am trying to stream video live using ffmpeg, Input is from a UDP Source. Most of the time it works fine, but I could see the following log lines and ffmpeg stop's the conversion/feed push to the rtmp server. Few log lines below for reference. Is this issue related to network on reaching the destination or source or something that i need to change in the ffmpeg command?</p>
