gstreamer error

[sdarktemplar]

I could use rkmpv to play mp4 by hw decoder,

but when I use gstreamer I got error as below:

rock64@rock64 # gst-launch-1.0 playbin uri=file:///home/rock64/Videos/TEST.mp4 video-sink=kmssink
Setting pipeline to PAUSED ...
ERROR: Pipeline doesn't want to pause.
ERROR: from element /GstKMSSink:kmssink0: Could not open DRM module (NULL)
Additional debug info:
gstkmssink.c(709): gst_kms_sink_start (): /GstKMSSink:kmssink0:
reason: No such file or directory (2)
Setting pipeline to NULL ...
Freeing pipeline ...


do I miss anything?

Thanks

regards,
Yui
