And how can I tell FFMpeg (which I use to play an RTP steam), to look at RTP packets to find payload type? RFC 4566 (5.14), if more than one payload type numbers specified in m= line, first one SHOULD be used as the default format for the session. So, if I specify more than one payload type, and the first payload type number I listed in m= line is not the payload type being used to stream, FFMpeg library just hangs on avformat_find_stream_info() call, waiting for a packet with appropriate payload type.

With my best regards,
