dec parameter set

billy david

hi all ,now when i create the dec link ,i set the below parameter

decPrm.chCreateParams[i].algCreateStatus = DEC_LINK_ALG_CREATE_STATUS_DONOT_CREATE;

so i can call the function Vdec_createChn() to create a dec channel direactly

then now i found the i can disable a dec channel ,but if i call the enable function to enable the disable dec channel ,that can not enable dec?so why?

On enabling a previously disabled decode channel , the decode will search for a key frame (IDR) before resuming decode.

For this application should set isKeyFrame frame flag for IDR frame in the Bitstream buffer structure fed vi Vdec_putFullBitstreamBuffer.

you mean that if i want to enable the dec channel successly,i must confirm that the first frame to send the enable channel is IDR frame?
