Hi all,
I want to run JPEG and MPEG4 encode on DM355 board, and I wrote a
demo referencing the code in ../DVSDK_1_00_30_xx/demo/encode/* and the
code in ../DVSDK_1_00_30_xx/examples/jpegenc/*. After I run the demo,
it said on the terminal:
/*********************************************************/
r...@21:/opt/dvsdk# ./encode_test_jpeg -v 1.mpeg4 -r 640x576 -b 384000
Encode demo started.

CMEMK Error: GETPHYS: Failed to convert virtual 0x4001cbe0 to physical.
CMEM Error: getPhys: Failed to get physical address of 0x4001cbe0
Don't know much about applications, but 0x400xxxxx seems more like a
physical rather than virtual address to me. Just a thought...
no, 0x4001cbe0 is a virtual address
I doubt you can run JPEG and MPEG4 at the same time, I think they share the HW.
but, in any case, run with CE_DEBGU=2
