WebM with audio and video more than 20 seconds latency

Hi,

I stream video and audio in WebM container.
Video: VP8
Audio: Vorbis

gst-launch
videotestsrc ! video/x-raw-rgb,framerate=5/1 ! ffmpegcolorspace ! vp8enc ! queue ! mux. 
audiotestsrc ! audioconvert ! audioresample ! vorbisenc ! queue ! mux.
webmmux name=mux ! tcpserversink port=8555 host=localhost

Client side simple HTML5 video tag <video src="http://localhost:8555"></video>

Problem:

It takes more than 20 seconds to play video with audio on the client side.
Without audio it takes just 1-2 seconds to start.

So what do you think?

Any ideas appreciated.

Thanks, Sam

Stream without audio for now leave note that audio has latency most Vsaas as opposed to kids don't care about audio I think if u say audio stream will load in 20 seconds perhaps adding some animation it's ok
