@zhaitianduo @miruna-craciun Another problem with KV. It appears that the images are rotated when processed in KV. My device is a Fire HD 2019 and has Android 9 https://kartaview.org/details/7728793 https://kartaview.org/details/7728521 https://kartaview.org/details/7724585 https://kartaview.org/details/7724569 https://kartaview.org/details/7724553 https://kartaview.org/details/7724521 https://kartaview.org/details/7724489 https://kartaview.org/details/7724473 https://kartaview.org/details/7703369 https://kartaview.org/details/7703353 The camera is positioned on the bottom right when recording the images. Any way this can be fixed?

Hi, Bryce.

Could this be related to the Android version? Wondering if you could flash a more modern version of Android? That's purely a guess, by the way.

Cheers,

Chris

https://kartaview.org/details/7841865/ FIXED! All I had to do was this copy files from sd card (Android/data/com.telenav.streetview/files/OSV/SEQ-replace-this-with-hex) to a folder on your computer get ffmpeg and perform the following step per folder for %i in (*.mp4) do ffmpeg -i "%i" -vf "rotate=PI:bilinear=0,format=yuv420p" -metadata:s:v rotate=0 "%~ni-out.mp4" get bulkrename utility and drop the last 3 digits from the file (omitting out from the filename) EXCEPT the tracks.txt.gz! place files back on sd card, placing them in Android/data/com.telenav.streetview/files/OSV folder. Follow steps to upload data from card to KV's servers. If you dont have a sd card, its pretty cheap (around $5 for a 16gb one) or you can use a DATA transfer cable that is USB Type C! Closing issue.
