Hi @Jason ,
So we did some testing internally and the reason that DepthAI encoding isn't working on Pi Zero is because of this bug:
@GergelySzabolcs has done 1080p recording with DepthAI on Pi Zero.
And actually, if you want to get this going now, our Gen1 API is successfully doing this. So you could actually use it here:
And the instructions for recording the video are here:
(These are the Gen1 instructions.)
So this actually should be able to record full HD to the Pi Zero. You just won't be able to play it back on the Pi Zero. But you can SCP it off and play it elsewhere for example. And you should be able to record as long as the microSD can handle - so you should be able to record hours of footage if you have a decent-sized SD card on the Pi Zero.
We're in the midst of debugging why we have this issue with Pi in general in Gen2. So far we don't have great leads.
I'll try to remember to post here once this is resolved in Gen2 API, but for now can use Gen1 for this and it should work fine. And we'll definitely update the linked Github issue above.
