Adjust/Disable Jitter Buffer in WebRTC

Hello,

I am currently experimenting with kurento to get a very low latency webrtc stream. For this I am using the rtp example for my experimentation.

When my network is fine, the latency seems to be okay but when the network quality deteriorates, the stream I am seeing in kurento is lagging. I discovered that kurento is using a jitter buffer to compensate for poor network quality. However in my usecase I would rather drop frames than to buffer frames to ensure the latency stays low.

I checked the documentation to see if there is a configuration parameter. Unfortunately this are still seems to be undocumented.

Can I disable the jitterbuffer in Kurento or at least adjust its value to a place that suits my needs?

Thanks in Advance!

I think this is not possible at the moment.

There is also a jitter buffer inside the web browsers, in my experiences its between 40-60ms.

Why is it not possible? Has the Kurento team considered adopting the adaptive bit rate control used in Chrome?
