Texas Instruments provides DSP algorithms for the OMAP 3 platform used in a number of devices like beagleboard, Nokia N900, and Nokia N9. The gst-dsp project aims to provide GStreamer elements to take advantage of those algorithms. The list includes video/image decoders and encoders. Unlike other similar projects there are no dependencies (no openmax, no libtidspbridge). The features include: * video decoding (MPEG-4, H.263, H.264, WMV) * video encoding (MPEG-4, H.263, H.264) * image encoding/decoding (JPEG) * zero-copy The advantages over other solutions are: * simpler code (5k vs 50k) * better performance (4x) == building == There are no dependencies, so just: ./configure make If you are using an old version of TI's dspbrdige driver: DSP_API=0 ./configure == tidsp == You'll need a kernel with tidspbridge driver, the DSP firmware in /lib/dsp, and the DSP running a proper baseimage (baseimage.dof). See: http://omapzoom.org/wiki/L23.i3.8_Release_Notes == compatibility == gst-dsp supports multiple versions of DSP socket-nodes, and tidspbridge driver. socket nodes: L23.i3.8: SN_API=2 L23.i3.3: SN_API=1 Note that the jpeg encoder in L23.i3.8 doesn't work (they compiled it wrongly), and the one in L23.i3.3 might hang on some pipelines; you might have to turn off enable-last-buffer, since only one output buffer would be available at any given time. tidspbridge: since staging: DSP_API=2 since ioctl renumbering: DSP_API=1
