Download video data from robot camera
Hello everyone,
I have collected sensor data from my parot uav model with the following commands
roscore
rostopic list
rosbag record -O subset /drone/imu
rostopic echo -b subset.bag -p /drone/imu > data.csv
When I tried the same method to download camera data as video or image sets, the downlodaded file can not be opened
rosbag record -O subset /drone/front_camera/image_raw/compressed
rostopic echo -b subset.bag -p /drone/front_camera/image_raw/compressed > data.mp4
What can be the reason for that? The image_raw files are being recorded as a .bag file, but I can't download and see it in my computer. Am I making a mistake with the video or image format I am trying to download?
