@asherAbecasiss thanks for posting the full log.

Regarding the crash, it should be gone with the latest commit (67198cc).

Regarding support for the camera, the problem is that the camera is advertising an AAC track with the cpresent attribute set to "0" and no configuration:

a=control:track2
a=rtpmap:97 MP4A-LATM/16000/1
a=fmtp:40 profile-level-id=1709392648;cpresent=0;config=
a=sendonly

The RFC6416 specification says that

"cpresent": a boolean parameter that indicates whether audio payload configuration data has been multiplexed into an RTP payload (see Section 6.1). A 0 indicates the configuration data has not been multiplexed into an RTP payload, and in that case, the "config" parameter MUST be present

Therefore, the RTSP implementation of the server you're interacting with is wrong - is it a camera or a custom server? if it's a custom server, change the code. Otherwise, if it's a camera and nothing can be touched, provide the model and we'll see what we can do about it.
