Failed to set remote answer sdp when running in Tablet

[ronbarrera]

I modified this to only received video and audio from the master and android app as viewer, however when running the app in a tablet, I get the following error:

E/KinesisVideoSdpObserver: onSetFailure(): Error=Failed to set remote answer sdp: Failed to set remote video description send parameters.

The offer I'm sending is the following:

I've enabled ENABLE_H264_HIGH_PROFILE to true and false to test, but I get the same error. Anyone have an idea about this issue?

The problem was with the master device not the android client app

@ronbarrera can you tell me what exactly was the issue on the master side? I might be facing a similar problem

[ronbarrera]

@CatsNipYummy, sorry for the late response, honestly not sure, I wasn't working on the master side, but I think they updated webrtc on their end, I will try to find out more info and post it here.
