我正在开发 yocto 项目 imx6 板，并且在视频流、gstreamer 和 RTSP 服务器上成功安装了问题。
在这个命令之后
"gst-launch -v \rtspsrc latency=300 location=rtsp://10.55.165.
128:9001/1.mp4 name=s ! \ rtph264depay ! queue ! mfw_h264decoder ! xvimagesink
"
我收到如下错误：
H264D_ARM11_02.06.03 build on Apr 16 2013 13:30:59.
MFW_GST_H264_DECODER_PLUGIN 3.0.11 build on Sep 19 2016 13:40:12.
