Display flir rtsp camera streaming in Dashboard

I have found a temporary solution. I'm conventing rtsp stream into a http stream using VLC. Once I have found the proper transcoder format (VP80 and Vorbis (Webm) and VP8 video codec), it works fine. But this is not yet satisfying because VLC has to run in parallel and need to be launched manually. Is there a way to make it run with a control fonction. I did try but didn't manage.
VLC suggest this flux code : ":sout=#transcode{vcodec=VP80,vb=2000,scale=Automatique,acodec=vorb,ab=128,channels=2,samplerate=44100,scodec=none} :no-sout-all :sout-keep"
