Can you please also share with us how to run the video playback use case? I believe the readme located here: http://code.entropywave.com/git?p=ew-leonora-beagle-demo.git;a=blob_plain;f=README;hb=master has instructions on prerequisites, build process, installation but the command line used to run the actual use case was missing. Thanks a lot for this!

Thanks. Can someone please confirm that the released N900 device from Nokia running Maemo is actually using this gst-dsp software stack? If not, can you please let me know what other gstreamer release it might be using? Pretty neat! Thanks.

The '6467, for example, uses 2.5 W for "typical" usage (I imagine transcoding 1080p is higher), whereas the OMAP3430 is rated for 540 mW for a video encoding application. I did not measure these numbers, so I can't vouch for their accuracy, but 5x the power for 5x the performance seems reasonable. anonymous:
