Version 1.0-rc1 is released with new Python SIP, Nokia APS support, and IPP codecs

“Good news, everyone” [Professor Hubert J. Farnsworth, Futurama]

This is an interim release, intended to mark the end of features development in the trunk. From now on, it will be tests and bug fixes only, until we reach 1.0. This will be our first proper stable release, and it will be given a separate branch, to isolate it from bleeding edge developments in the trunk.

Because of that, there has been a bit of “pressure” to stuff in as much features as possible on this release, since this is the last change to include them in 1.0. Here are some of them:

  • Integration of Intel® IPP Codecs.  This brings us with bunch of new codecs into PJMEDIA, such as G.722.1, G.723.1, G.726, G.728, G.729A, AMR NB, and AMR WB. Basically the lot! For more info about this integration, please see here.
  • New Python API. We discussed this on this blog a month ago here, basically it’s a new Python API for PJSUA-LIB, it’s much easier to use, and it also has a more thorough documentation/tutorial. Please check that out.
  • Nokia APS Support. The Nokia Audio Proxy Server is a wrapper to Nokia S60 sound device, it has much lower latency than Symbian MMF API (the traditional sound device that we support), and it also opens up support for device’s native codecs such as AMR, G.729, and iLBC which we can use in the future.  Although this API has been deprecated by Nokia in FP2, still there are lots of S60 and FP1 devices out there, so this is worth supporting.
  • New Echo Suppressor. Good for mobile devices, we discussed this in this blog here.

And some more. For more information regarding this release, please visit the download page.

Enjoy.
