Supporting q264 format

[DrumSergio]

This issue comes from this old topic https://forum.qnap.com/viewtopic.php?t=90200

Our QNAPs are recording in q264 format, but in fact it's h264 format. It's simply a programming line: ie. if "q264" then use "h264", so we can play it, instead of changing headers for every file!

Thank you!
