Maybe you could try to reproduce it in C++? That would make it easier to debug.

@JonasVautherin Thanks for getting back to me, I'm not sure how one would do that on Android.

I was able to get more detailed logs by removing log filters,

I was finally able to grab the Tombstone for the crash,

tombstone_33.zip

JonasVautherin commented 6 months ago

I'm not sure how one would do that on Android.

No need to do it from Android: try to reproduce in C++ from your computer :blush:

rayw-dronesense commented 6 months ago

@JonasVautherin - Hmm...I'm unsure on how to do this on the computer - the camera module only emits with the real drone, as far as I'm aware, and it is connected via this Android-based controller.

JonasVautherin commented 6 months ago

Oh, I see... What controller is that?

julianoes commented 6 months ago

Can you share the xml camera definition file that it parses? Using that we should be able to spot the problem or reproduce it?

This doesn't look right:

Given that the xml looks correct, presumably the type set in param_get_ext or param_set_ext is not correctly set by the camera implementation. Can you check that part?

Hi @julianoes ,

Unfortunately we don't have access to the source code for the drone.

What we do know is, the same logic and drone works using the mavsdk-server-android 1.3.2

julianoes commented 6 months ago

Right, so it could also be a mavsdk regression then... :thinking:

I guess we need to add a bunch of debug output and then try that.

Are you compiling mavsdk_server yourself? In which case you could add some debug things around where std::stoul happens. Otherwise, I need to make a release for it...

rayw-dronesense commented 6 months ago

Are you compiling mavsdk_server yourself?

@julianoes - Nope, this was repro'd with the latest artifacts published on maven.

julianoes commented 6 months ago

Right, well, I need to put this on my todo list. If it's urgent to you, consider github sponsoring.
