Hi，all：

gstreamer commnad is：

gst-launch-1.0 playbin uri=http://192.168.1.160:8080/ts

1.when /usr/lib/gstreamer-1.0/libgstaiurdemux.so exist ， will hold at the first frame

Prerolled, waiting for buffering to finish...
Pipeline is PREROLLED ...
Setting pipeline to PLAYING ...
New clock: GstAudioSinkClock

2.when remove /usr/lib/gstreamer-1.0/libgstaiurdemux.so， it can play ， but not smooth

Prerolled, waiting for buffering to finish...
Pipeline is PREROLLED ...
Setting pipeline to PLAYING ...
New clock: GstAudioSinkClock

Hi，igorpadykov：

Thanks for your reply.

I use greamer's files in fsl-image-qt5-validation-imx-xwayland-imx6qdlsolo.tar.bz2.

----------------------------------

tar jcvf ~/temp/solo_gstreamer_all.tar.bz2 usr/bin/gst* usr/lib/gstreamer-1.0/

----------------------------------

but still stop at the first frame.

command is:

gst-launch-1.0 souphttpsrc location=http://192.168.1.160:8080/ts ! typefind ! aiurdemux name=demux demux. ! queue max-size-buffers=0 max-size-time=0 ! vpudec ! overlaysink

log is :
