<p style="margin-top:0;margin-bottom:0">I am facing issue in opening the live encoded h264 stream of 8MP resolution over tcp server in Qt Application. To open the stream in ffplay, I give following command in terminal and it is able to play it:</p>
<p style="margin-top:0;margin-bottom:0"><i>ffplay -f h264 -codec:v h264 -probesize 32M <tcp://ipaddress:port></i></p>
<p style="margin-top:0;margin-bottom:0"><i><br>

<p style="margin-top:0;margin-bottom:0">But when I try to open the stream in Qt Application, avformat_open_input() gives error
<i>Invalid data found while processing input</i>.</p>
