Really thinking using the rock64 as the board for my homemade dashcam setup. I can use USB cam modules for both rear and front, with ffmpeg combining the two. Using one of my spare 500GB m.2 boards I have laying around in my rig not doing anything I can use as the storage and could probably record entire journeys no problem. I could also then add a mic too and have an in-car recording setup. The cherry on top would probably be using it as a bluetooth sink to send audio via the aux cable in the speakers.
