Hi,
gst-dsp is GStreamer plug-in to utilize Texas Intruments' DSP
algorithms for OMAP3 platforms (using dsp-bridge). It's used in the
official Nokia N900 system, but should work on any platform (has been
tested on beagleboard).
It's time for the next release. There have been a huge amount of
changes, mostly for stabilization, but also some new features:
* dynamic bitrate for venc
* support to force keyfrane on venc
* WMV support
* Improved H.264 decoder support
* New H.264 video encoder
* Improved venc latency
In general it seems almost ready for the 1.0 release... once the WMV3
issues have been solved, and the parsers are finalized.
Thanks to all the people that contributed to this release. Here's the shortlog:
