Added wrapper for the move by command. #103

AndreasAZiegler · 2017-03-31T13:32:54Z

Added wrapper for the move by command in the Parrot SDK. This command moves the drone to a relative position and rotate heading by a given angle.

Thank you @AndreasAZiegler for this PR.

Please see my inline comments.
Please consider updating the documentation (in the docs folder) + add your information as a contributor to it.
Please consider adding unit tests for these two functionalities (check bebop_driver/test folder and this part of the docs)

Do you need the following class to be part of this file? Unfortunately this file is auto-generated and will be overwritten by subsequent SDK updates.

No, shouldn't be needed. I guess I was not enough careful while adding files.

+void Bebop::MoveBy(const float& dX, const float& dY, const float& dZ, const float& dPsi)


Please change float to double in the signature since the twist message fields (that you pass here) are all doubles.

+void BebopDriverNodelet::CmdMoveByCallback(const geometry_msgs::TwistConstPtr& twist_ptr)


Please lint this function (indents, extra blank lines).

I'm not sure, if I understood your comment correctly. Pleas let me know, if it's the case.

I don't think %f is correct here, since the input is of type uint8_t. Please fix.

What if format_ptr->data is not set to a value supported by SetPictureFormat? Please add a guard (or a warning) against this.

+    const uint32_t num_bytes = avpicture_get_size(AV_PIX_FMT_RGB24, codec_ctx_ptr_->width, codec_ctx_ptr_->width);


Could you please explain this change?

The current ffmpeg uses AV_PIX_FMT_RGB24. Older versions of ffmpeg provide PIX_FMT_RGB24.

I applied your feedback and also added a unit test. As for the usage of the event "RELATIVE MOVE ENDED" arsdk version 3.12.6 is required, it would be good, if you can merge the PR "Add support for SDK 3.12.6 #120" before this one. I and then adapt the unit test accordingly.
