I'm getting this error from mpegtsmux:
Oct 22 11:49:53 qt5122 qtec-mediamixer[272641]: 0:00:01.244140161 272641
0x5556a57b51e0 WARN basetsmux
gstbasetsmux.c:811:gst_base_ts_mux_create_pad_stream:<mpegtsmux2> error:
Could not create handler for stream
But I can't figure out what it is about, what is the problem.
If I look at the .dot file from the ERROR all looks fine. All seems
linked and all CAPS seem correct.
Also, when I ran a simplification of my program pipeline using
gst-launch all works:
gst-launch-1.0 udpsrc address=224.1.1.1 port=5000 multicast-iface=eth1 !
application/x-rtp,media=video,payload=33,clock-rate=90000,encoding-name=MP2T
! rtpbin ! queue ! decodebin caps="video/x-h264" ! h264parse !
"video/x-h264,stream-format=byte-stream,alignment=au" ! tee name=t !
queue ! "video/x-h264,stream-format=byte-stream,alignment=au" !
