Implemented useful improvements, the benefits of which were confirmed during testing. We could also reproduce improvements in scores.
Note, that FEC problem itself was possibly fixed in 1273, which lead to even better results.

We expect the contestant to take part in round 3. Suggested priorities:
1. Improving audio quality scores as compared to newunstable.
2. Finding and fixing new thread blocking, deadlock problems etc.
3. Improving latency as compared to the stable version.

This is not an issue, just a request. If there were any specific network conditions which you used to optimize the initally provided library, you are welcome to share test sequences as well as your results. e.g.:

->loss(12)->rateControl('32kbit')->networkType('3g')
Stable version: 3.0
My submission: 3.3

->loss(3)->rateControl('64kbit')->after(3)->loss(20)->rateControl('8kbit')->after(3)->rateControl('64kbit')->networkType('3g')
Stable version: 3.2
My submission: 3.4

We will re-check your results and may use the sequences you provide to test other submissions.
