Hi Carl,

I don't know how to force 1 core only...

By the way, I'm trying to build again without network connected and it seems to work better. I only get warnings about "swp{b} use is deprecated for ARMv6 and ARMv7".

Yet another idea: we will not use RPi2 to encode DCPs as a master computing node, only as an encoding server. Would it be possible to modify compilation scripts to process the relevant source files only?

Thanks for your help,

Fred

Hi Fred,
Maybe there's a bug with DCP-o-matic on ARM... can you try with 1
processing thread to see if the memory usage remains stable?
Regards,
Carl
