[Elphel-support] Record and watch simultaneously?

[Brian Burke]

Great to hear - thanks Sebastian. I figured if there were "problems", it'd
be due to the processor not being able to keep pace, or with two processes
trying to grab images from the circbuf at the same time.

Yes, works very well.

Ethernet is 100Mbit/s and storage media max ~144Mbit/s (also depends on how
fast you can write to your HDD/SSD/CF card)

So if you get near the max. of Ethernet bandwidth with your video stream you
could have short shuttering in your live video but not in your camogm
recording.

If you get over the bandwidth limit of ~144Mbit/s, the circbuffer will
overflow and camogm will have to restart recording loosing a bunch of
frames.


A tool that might be interesting for this is the buffer monitor which helps
monitor the state of the circbuffer:
