Comment (by tpol):

 It looks like FFmpeg incorrectly parses the SDP information in case of
 MPEG-2 transport stream.

 When payload type is 33, it uses the Session control url instead of the
 Media control url in RTSP SETUP request.

 ''a=control:rtsp://..:8554/''
 vs
 ''a=control:rtsp://..:8554/trackID=0''

 I was able to receive the stream with the following fix:
 {{{
 diff --git a/libavformat/rtsp.c b/libavformat/rtsp.c
 index c153cac..b8c7128 100644
 --- a/libavformat/rtsp.c

          break;
      case 'a':
          if (av_strstart(p, "control:", &p)) {
 -            if (s->nb_streams == 0) {
 +            if (rt->nb_rtsp_streams == 0) {
                  if (!strncmp(p, "rtsp://", 7))
 }}}
