sensor_msgs/Image Issue about rosintegration

[tsender]

Hi @jonathanembleyriches ,

I can tell you this is the line triggering that error message:

ROSIntegration/Source/ROSIntegration/Private/rosbridge2cpp/TCPConnection.cpp

Line 194 in 46dd966

if (!bson_init_static(&b, binary_buffer.GetData(), bson_msg_length)) {

I am not quite sure what is causing this to occur on the little info you provided. Can you please provide more details about your rosbridge setup? Can you subscribe successfully to other types of messages in UE4? Is it just the sensor_msgs/Image message causing a problem? What happens if you lower the camera resolution, will ROSIntegration parse the BSON message then?

Just throwing out some ideas to help narrow down the problem.

Hi,

I manually changed the ros bridge suite code (not this plugin) which was encoding and sending over TCP. It appears that it was encoding the message twice and therefore creating issues on the receiving end. I'm not entirely sure why it was doing this. Closing this issue as it appears to be due to this. Thanks for your response!
