[DISCO] `Video streaming started` encounters `shared_ptr` error

[weiweikong]

My platform is

- Indigo
- Ubuntu 14.04
- Disco Platform

When running roslaunch bebop_driver bebop_node.launch, we received

which seems that ROS has been correctly connect with Parrot Disco, but after a while, we received the following errors

I googled and found that it might be the boost::shared_ptr error, however, I am not so familiar with boost and bebop_autonomy source code.

Would it be possible to share some information about this issue？

Thanks.

Thanks for this bug report. Unfortunately I do not have access to a Disco FPV and I can not confirm that this driver works (at least without further modification) with the Disco. However, the issue you are facing might be caused by a bug in the driver's code.

Could you please change this line from:

if ((gps_state_ptr->header.stamp - last_gps_time).toSec() > util::eps)

to

if (gps_state_ptr && ((gps_state_ptr->header.stamp - last_gps_time).toSec() > util::eps))

and recompile/test the driver?

[weiweikong]

@mani-monaj Hi, thank you for your kind reply.
I recompiled the whole package as you recommended, and received the similar errors

by running

roslaunch bebop_driver bebop_node.launch 

Should we change all the shared_ptr related codes? Thanks.

[mani-monaj]

Thanks for the update. I think the problem is that the driver's code does not properly guard against all cases of NULL [shared] pointers before accessing them.

Looking at the code and your error report, I guess the problem is from this line:

if ((speed_esd_ptr->header.stamp - last_speed_time).toSec() > util::eps) 

Could you please change it to

if (speed_esd_ptr && ((speed_esd_ptr->header.stamp - last_speed_time).toSec() > util::eps))

Then recompile and test?

Since I do not have access to a Disco, it is helpful if you could run the driver in a debugger such as gdb. This is what I use to run a Nodelet with gdb:

$ rosrun --prefix "gdb --args" nodelet nodelet standalone bebop_driver/BebopDriverNodelet

Prior to running this command, please catkin clean your workspace and recompile it with catkin build -DCMAKE_BUILD_TYPE=Debug [or -DCMAKE_BUILD_TYPE=RelWithDebInfo. When gdb starts, use the run command to execute the code. When it SEGFAULTS, use bt to get the call stack that led to the fault. You may find this tutorial helpful.

@mani-monaj Hi, sorry for my late testing. The camera streams was receivedl, as shown

but there were some warnings related to H264Filter

[mani-monaj]

Thanks @weiweikong for the update.

1. To clarify, does the changes I propose fix the segfault issue? Could you please send a Pull Request with all those changes if that's the case?

2. Could you please run the driver, do a rosbag recored -a and upload/share the resulting bag file with me? It can be huge since it will include non-compressed image topics. The order I suggest to run the commands is:

3. Run roscore

4. rosbag record -a

5. Launch the driver

6. Kill the recored script after 30 seconds or so.

[weiweikong]

Sorry for my late replay.

rosbag record -a failed

When I run the command line

rosbag record -a

there were following warnings and the nodes crashed

it seems that the bag record could not save the data correctly.
However, without rosbag action, we could see the image stream correctly through rqt_gui.

Running the driver again, sometimes encountered following errors.

Other topics information

Would it be possible to access autopilot data such as IMU, gyro raw data through the driver by ROS node?

[weiweikong]

@mani-monaj Any update about other topic information with ROS node?

[weiweikong]

Any update @mani-monaj ?

[mani-monaj]

@weiweikong Sorry for my delayed response. I will be back on the development track very soon. I will update this issue with my answers. Any update on your side?

[weiweikong]

@mani-monaj No more update. : (

[thomas-bamford]

Hello @weiweikong,
Sorry for the late reply. The bebop_autonomy ros driver is currently limited to the information that is provided by the Parrot, so information such as IMU, gyro raw data is not yet available. Here is a link to the list of information that these Parrot drones can provide http://developer.parrot.com/docs/reference/all/index.html. We hope to work towards providing support for the Disco platform (which upgrading to the latest SDK will add some new information for). Please let us know if there have been any updates from your side that you would be willing to collaborate to this project.
Thanks.

[thomas-bamford]

Disco is supported in #168.
