Today, I’ve released a new version of libnice : 0.0.11.
This is an important milestone for libnice because this is the first version that has support for a reliable transport.
As I explained in my previous post, this version uses a TCP over UDP implementation that is compatible with libjingle’s pseudotcp (it’s actually a copy of it).
The change is very minimal, all you need to do is call nice_agent_new_reliable instead of nice_agent_new and libnice will take care of making your components reliable. You will also need to pay close attention to the return value of the nice_agent_send as well as the reliable-transport-writable signal. But everything else should stay the same.
If you’re interested in the TCPoUDP implementation, you can also use it directly in your application, outside of libnice, as it is now provided as its own class.
The documentation has now been updated, and you can read more about it here.
Let me know if you will be using this much requested feature!
First news I’d like to share is about libnice!
I’ve been working lately on adding reliability to libnice. This means that you could be using libnice as a reliable socket.. This is accomplished using some form of TCP over UDP, which is compatible with google’s libjingle implementation.
The API doesn’t change much, you only need to call nice_agent_new_reliable, and there’s a new signal ‘reliable-transport-writable’ in case you fill in the internal buffer and nice_agent_send starts returning -1. That’s all!
I know a lot of people were waiting for a reliable transport with libnice. I’ve discussed with many people during GCDS and most of them said that they’d like to see some kind of TCP over UDP in libnice, so I’m happy to say that I finally got around to doing it.
I also decided to make this TCPoUDP algo into its own GObject and make it available through libnice, which means that you could use the TCPoUDP implementation directly yourself, outside of libnice, in your own applications, if you ever wanted to!
Expect this new exciting feature to become available to you in the next release of libnice!
