RTMP h264/speex to HLS h264/aac

I've added h264parse before mpegtsmux and now I'm getting hls segments but
I can't play them.
I'm still getting the gst_caps_can_intersect error.

gst-launch-1.0 -v rtmpsrc name=rtmpsrc
location="rtmp:/localhsot/app/stream" ! \
    flvdemux name=demux \
    demux.video ! h264parse ! mux.  \
    demux.audio ! speexdec ! audioconvert ! voaacenc ! aacparse mux. \
    mpegtsmux name=mux ! hlssink
