Hi,

gst-dsp is a GStreamer plug-in to utilize Texas Intruments' DSP
algorithms for OMAP3 platforms using the tidspbridge driver.

This is a major release, many features have been implemented:

 * Huge reorganization
 * Support for IPP (image post-processor)
 * Support for AAC decoder
 * Support for VPP (video post-processor)
 * Huge optimization for video encoders
 * Improvements on caps negotiation
 * Improvements on H.264 keyframe generation
 * Improvements on hang detection
 * Memory leaks fixed
 * Fixes for WMV
 * H.264 encoder tuning
 * Support for gtk-doc
 * Fix for JPEG encoder

Again, we have a lot of contributors. Thanks to everyone!
