Bottom Camera Feed about ardrone_autonomy

you have at first to switch with the service to the bottom camera.

Services
Toggle AR-Drone's Camera

Calling ardrone/togglecam service with no parameters will change the active video camera stream.

look in the readme

I have the same problem. Even when toggling the service (as suggested in the documentation) the bottom camera's topics never seem to be published. I haven't looked in the source code, but there might be some bug. Have verified the camera toggle works for you? Are we doing something wrong?

I toggled the camera stream using the service, but still no stream from the bottom camera...only front camera gives a steady video stream...
Is this a bug?

Are you using the latest version of the code? I can confirm that the bottom camera stream works after calling the service.

[ardrone driver running]
rosservice call /ardrone/togglecam 

Setting camera channel to : 1 (output from driver)

rosrun image_view image_view image:=/ardrone/bottom/image_raw
[or]
rosrun image_view image_view image:=/ardrone/image_raw

Do you receive the "Setting camera channel to : 1" from ardrone driver?

Thank you Mani, it works well now..not sure what I did wrong earlier with mmyself's comment...
Will it be possible at some point to receive a simultaneous stream (bottom image embedded in corner of front image) ?

You are welcome.

Drone 1 with firmware 1.X supports Picture in Picture mode, but in Drone 2.0 this mode is not supported anymore.

I am also having the same issue. I can toggle the cams easily with the iPhone app. However, the camera does not change using "rosservice call /ardrone/togglecam". I am using the latest version of the code and I do get the messages saying "Setting camera channel to : 1" or "Setting camera channel to : 0".
I also tried changing the parameter "video_channel" so as to change the default camera view to 1, however it does not have any effect either.
Any help in this regards will be greatly appreciated.
