Re: [gst-embedded] Need help to play HD file on Beagle Board

 Judging from your discussion with Felipe this is probably no longer 
relevant, but perhaps somebody else may benefit...

 You need to load the cmem module - it allocates physically contiguous 
memory for use by the hardware (which is actually completely unnecessary 
because the ISP peripheral that does the rendering has an MMU, but that's 
how TI implemented their DMAI...).  When loading the module, you have to 
specify the sizes you want to be able to allocate.  I have this:

# CMEM Allocation
#    1x3317760            Circular buffer
#    3x1843200            720p video buffers
#    3x829440             PAL video buffers
#    1x691200             NTSC video buffer
#    1x345600             Underlying software components (codecs, etc.)
#    1x1                  Dummy buffer used during final flush
modprobe cmemk allowOverlap=1 phys_start=0x86300000 phys_end=0x87300000 \
       pools=1x3317760,5x1843200,3x829440,1x345600,1x691200,1x1459200,1x1


 OpenEmbedded should set up sane defaults, though.
