安装MMP和gstreamer-rockchip后不能正常运行

如图所示，已经安装好MMP库和gstreamer-rockchip插件，本来想执行
#sudo gst-launch-1.0 v4l2src device=/dev/video0 ! "image/jpeg,width=1280,height=720,framerate=30/1" ! jpegdec ! videoconvert ! queue ! mpph264enc ! queue ! h264parse ! flvmux streamable=true ! queue ! rtmpsink sync=false location='rtmp://10.50.1.202:1935/live/test'
推流，但出现问题。然后缩小gstreamer launch，简化为
#sudo gst-launch-1.0 v4l2src device=/dev/video0 ! "image/jpeg,width=1280,height=720,framerate=30/1" ! jpegdec ! videoconvert ! queue ! mpph264enc ! appsink
仍出现问题，有人遇到过类似的问题吗？

此外，执行mpi_test时，出现如下报错：
[toybrick@localhost ~]$ mpi_test
mpi_test: mpi_test start
mpi_test: mpi_test decoder test start
mpi: mpp_create enter ctx 0x7fc3520d60 mpi 0x7fc3520d58
mpi: mpp version: Without VCS info
mpi: mpp_create leave ret 0 ctx 0x1ad20fc0 mpi 0x7f902586f8
mpi: mpp_init enter ctx 0x1ad20fc0 type 0 coding 0
mpp: unable to create unsupported type 0 coding 0
mpi: mpp_init leave ret -1
mpi_test: mpp_init failed
mpi: mpp_destroy enter ctx 0x1ad20fc0
mpi: mpp_destroy leave ret 0
mpi_test: mpi_test failed


是不是还需要安装其他库呢？

我也遇到了一样的问题

请问解决了么，我这边也遇到了这个问题。
