Mumble 1.2.2 is currently in development. Since we just released version [1.2.1] we are not yet sure which features we want to add for this release.
We rely on your testing and feedback to improve Mumble, if you find any bugs in the current stable or in a recent snapshot please report them using our bugtracker. If you think we lack an important feature take a look at the corresponding feature tracker.
As development of 1.2.2 just started we did not yet implement any new features.
This section takes a peek into the future of Mumble's development. These features are what we would like to implement in future releases. There is no guarantee that we will ever get around implementing them however.
The current overlay texture system is designed for high speed texture transfers in a format that happens to be 60 pixels high. This is no coincidence.
Using H.264 encoding, 80x60 pixels is small enough that we can encode a 15fps video stream with minimal CPU impact. The bitrate will also be low (lower than existing audio streams), and with a bit of filtering the quality is near perfect. I really mean this; what filtering did for the audio quality in Mumble it also does for video quality.
