TMS320C6678: H264 video encoder

Part Number:TMS320C6678

hi,

i use H264 High Profile Encoder Version01.00.03.00  to encode video in HP profile  in multiple core (4 core) and it is work fine.

but when i want to encode my video by BP profile and change the profile from HP(100) to BP(66)   the program fail in all core  " Failed in Control call (XDM_GETBUFINFO) " ?!

in datasheet there is a benchmark table  that use BP and that is faster than HP.
