楼主
用了最新板的ubuntu 发现有个gstreamer在/opt/下
用了gst-inspect-1.0看了下插件 有mppvideodec, rtph264depay, rkximagesink
尝试来看下IP camera的rtsp串流...
指令：
gst-launch-1.0 rtspsrc location='rtspt://rtsplink:554/user=&password=&channel=&stream=.sdp' ! rtph264depay ! mppvideodec ! rkximagesink
但都没有出现串流画面, 卡在 mpp_rt: found drm allocator
用ctrl C 中断后，跳出 "gst_mpp_allocator_start: assertion 'size != 0' failed"
请问下各位有没有遇过这个问题呢
有确认过rtsp link是可用的了
