[dsp-flac] Dsp flac released

Ixonos Plc is proud to present a dsp accelerated flac audio codec for N800/N810 tablets. It should be possible to compile the code for 770 too but I don't have one so can't test it. The codec is based on libFLAC library by Josh Coalson. It uses dsp gateway for communication between arm and dsp. I have tested the codec with multiple music albums and when measuring the processing time with time command it seems to reduce the arm load almost 50%. In real time it seems to be slower than the arm only library but that is not a problem because it is still fast enough for audio playback. The release includes 2 files: 1) A quick and dirty debian package for making installation easier. I have tested it with N800 and N810 and it worked ok but you are using it at your own risk. The package is based on the ogg-support debian package by Tuomas Kulve. The debian package also includes an unmodified GStreamer flac plugin compiled from gst-plugins-good package. 2) a tar.gz package containing sources for arm and dsp code and the debian package. See README for installation and compilation instructions. For more details see release notes. This is the first release of the dsp flac codec. If there are some problems with the files, copyrights, licenses etc. please let me know. All comments are welcome!
