Hi, In the SDP negotiation each agent declares it supported receive capabilities. For H.264 it can be done using the profile-level-id mechanism suggested in RFC 3984. Let's assume that the offerer declared baseline profile level 1.1. As a result he is willing to receive different configuration e.g. up to CIF resolution with 7.5 FPS or up to QCIF with 30 FPS. Is there a method for the offerer to hint the answerer that he would like to receive in a specific configuration (e.g. QCIF 30FPS)? This can be useful if the offerer is a UE that is best suited for QCIF resolutions. Thanks, Shahaf
