求助： 关于rk3328 gst-launch-1.0 硬件解码

yjr1220

我的板子是3328,  用如下命令取流: gst-launch-1.0 rtspsrc location=rtsp://localhost:554/video.sdp latency=100  ! rtph264depay ! capsfilter caps="video/x-h264" ! h264parse ! mppvideodec ! videoconvert ! videoscale ! kmssink

执行几十次命令，偶尔会有一次显示图像。几乎每次都卡在如下log:
New clock: GstSystemClock
Progress: (request) Sending PLAY request
Progress: (request) Sending PLAY request
Progress: (request) Sent PLAY request
[ 1107.164227] rk_vcodec: vpu_service_ioctl:1894: error: unknown vpu service ioctl cmd 40086c01

请大家指点一下！ 谢谢！

gstreamder 会卡死在 decode_get_frame 函数。奇怪啊！
