HEVC 4K encoding

Hi,

I have a DSPC-8682 (octal DSP) card and installed Desktop Linux SDK version 1.00.03 and MCSDK Video version 2.2.00.45 on Ubuntu 14.04 (64 bit).

I can run the out of the box HEVC encoding demo available as part of the MCSDK Video (encoding the 720p airshow sequence). I can also encode a 1080p sequence using 4 chips (32 cores in total). But when I try to encode a 2160p sequence (using 64 cores) I get the following message from all nodes: "DSP codec create on node ... failed with error code -4". Using a different number of cores also fails with similar error messages.

Do I need to set specific parameters for 4K encoding?

Best regards,

Jurgen
