IPC_MOTION_START_C mq ?

[floronxt]

Hello roleo,

I am interested in reading the message queue to create a log. I came across IPC_MOTION_START_C “\x04\x00\x00\x00\x02\x00\x00\x00\x09\x70\x09\x70\x00\x00\x00\x00”.
Could you please explain in which situation IPC_MOTION_START_C occurs or what the difference is compared to the normal IPC_MOTION_START event?

If I remember correctly IPC_MOTION_C is the event used by the cams with fw 12.x
But I'm not completely sure, it's a piece of code written many years ago

Thank you very much for your help. I only have cameras with firmware version 9, which would also explain why I could never find an "IPC_MOTION_START_C" event. Thank you!
