I got the following error when I called setRemoteDescription on native IOS.
Failed to set remote video description send parameters
Please help!
The problem comes from this line:
profile-level-id 420029
My solution is simply to replace the "420029" by "42e01f", then everything works just fine. The situation seems related to the RFC 6184 8.2.2. You can visit here for more details.
