[maemo-developers] [ANN] gst-dsp 0.8.0 released

[From: Felipe Contreras]

Hi,

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

[I forgot to post this on maemo/meego mailing lists, so here it goes,
please CC gst-dsp at googlegroups.com if you reply]

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

 * Refactoring of DMA API
 * Fixes for newer DSP API versions
 * Add JPEG decoder implementation
 * Fix WMV support
 * Reorganize the way EOS is handled
 * Improve H.264 keyframe handling
 * Improve deinitialization on fatal errors (like MMU faults)
 * Fixes for ARMv7 speculative pre-fetching
 * Several improvements for encoding bitrate calculation
 * Add support for I420 color format
 * Correctly propagate aspect-ratio

And the usual bunch of cleanups and reorganization.

Also it's worth noting that this code has been tested on Nokia N900,
beagleboard, and future Nokia hw; with different DSP binaries;
L23.i3.8, L23.i3.3, and 0.3.5; and different DSP bridge driver
versions. For very old binaries, build with DSP_API=0, it's not
necessary to set SN_API yet, as the structures are binary compatible
with all the versions.

Moreover, this time I decided to package, this, and some related
packages in tarballs in order to help some distributions:

This time we have slightly more contributors, including even some
patches from TI. Thanks everyone!

Unfortunately this is still not ready for 1.0, the parsers need to be
cleaned up, fixed, and merged. And once tidspbridge 0.4 is tagged,
move to the new DMA API ioctls.

Finally, most likely the core of gst-dsp will move to a separate
library (not related to GStreamer): libtidsp, in order to be useful in
other projects. A sample of that has been submitted to FFmpeg for
review:

Enjoy ;)
