sorry, I know nothing about beagle, I can only tell you a little suggestion according to my knowledge about media player of android up to now. I am working on imx27 (from freescale) which integrates hardware codecs, and I am trying to utilize these hardware codecs and I am trying to know more about omx (I think you may need to search for this key words with android on internet), It seems this framework will be help(but I am not a little sure about this), meanwhile I am trying to find whether there is already some patches for android opencore (not kernel ) or to utilize imx27 hardware codec(as long as your hardware can successfully boot and your hardware codec has been successfully driven, the problem should not from the kernel level, so I won't search patches for kernel). I think (just my personal idea)/dev/pmem and /dev/pmem_adsp can't be created, it depends on your hardware whether support it. (once again , I am not so sure about this). best regards.

Any patch available for beagle kernel. Regards, HarishKumar.V 2009/3/11 susanner <[email protected]> Ah, I am not sure but you may need to correct the program: external/opencore/android/android_surface_*.cpp change mEmulation=true to use software codec. 在2009-03-11，"Harishkumar V" <[email protected]> 写道： Dear All, I have android running on beagle board.

Is there anything related with beagle kernel (2.6.27 from git mentioned in beagle wiki) or related with android framework. Using software codec means what, it will open which codec. Also initializing hardware what it means.
