Does your input sequence of NAL units (that you pass to "H264VideoStreamDiscreteFramer") contain SPS and PPS NAL units (either at the start of the sequence, or periodically within it)? If so, then the "H264VideoStreamDiscreteFramer" will automatically record these when they appear, and this will cause the proper "auxSDPLine()" to get generated. Alternatively, if you know the SPS and PPS NAL unit data in advance, you can pass them as parameters to the "H264VideoRTPSink" constructor (see "liveMedia/include/H264VideoRTPSink.hh").
