So here we go. A bit later than expected but finally done: v0.99d
Again combined change log since last productive release
New
* VR mode
* Start recording automatically on stock flight programs 360, up&out, circle
* Option to start recording on takeoff
* Autopilot for making 360 pano photos (for manual stitching)
Changes
* Circle POI speed more flexible
* Iframe period 0 (not suitable for video recording, only for long distance FPV)
* Bitrate Auto removed
Fixes
* Controller disconnected if user removes one or more stick axis configurations
* Option "Re-encode photos" lost when app closed
* DEMO: RTH failed if minimum altitude was set above the 2m altitude restriction
* Activation of APs silently failed if VPS not active
* Low battery reported as Error Code 13
So the autopilot is an AP that automatically does the pictures required for a 360° panorama. You will find the button I guess.
You can define the number of photos required for stitching under "Menu => Video & Photo => Photo". More photos result in more overlap for better stitching. I think 7 is the absolute minimum to have some overlap, 8 seems to be OK.
When activated
Tello will do a photo, download it (or retry up to 3 times if a download fails / expires), rotate to the next position, do the next photo,download, ... until it has done a full 360°.
It does not stich by itself but it groups the pictures into subfolders for easy stitching using some app. Maybe you want to check if this is suitable for your preferred stitching app. I tried Bimostitch and it worked well. So well that I have no plans of integrating the stitching part into TelloFpv.
This will finally become v1.00 in a couple of days, once manual is updated and any remaining bugs are fixed.
