Hi,Apoorv Thapliyal,
Thanks for the suggestions made.
We have tried 1.4.5 SDK on Voxl2 board and we are able to get snapshot in both QGC and also in /data/snapshots folder in the board .If we try to change resolution of snapshot in voxl-camera-server ,it is applied to resolution of snapshot saved in /data/snapshot folder in voxl2 board.
