RTSP streaming - FFMPEG question

[LegioX 2]

I am using IPTV to stream video from my IP cameras to Emby via WMC. When I increase the resolution on the camera I start seeing a lot of artifacts. A common resolution for this seems to be forcing the RTSP to use TCP instead of UDP. Normally you'd put this command into the ffmpeg string but I can't figure out how to do that with Emby or IPTV... I've tried to add the syntax (?tcp or ?svforcetcp) to the URL field in IPTV but this doesn't seem to have any affect...

 

Is it possible to append something to the string that is used to make the RTSP call?

Actually, I've figured out (via netstat) that those options are forcing the stream to TCP, but not fixing the issue.

 

This is what I'm experiencing: http://blog.quindorian.org/2013/03/fixing-rtsp-stream-corruption-guide-for.html

The issue is definitely related to displaying HD content.

 

I want to try increase the buffer but can't figure out where this is set. I assume it's in Emby Server somewhere but can't find an option on the server config pages.

Is there a way to set the packet buffer size?
