Stop synchronized video encoding/recording of the video group
#include <camera/camera_api.h>
camera_error_t camera_stop_video_group(camera_video_group_id_t group_id)
After having called camera_start_video_group() to start the video recordings and encodings, call this function to simultaneously stop the recording and encoding of video associated with the video group. After having called this function, you will then need to call camera_stop_video() or camera_stop_encode() for all of the cameras associated with the video group to finalize the video recordings and encodings.
CAMERA_EOK when the function successfully completes, otherwise another camera_error_t value that provides the reason that the call failed.
