Qt+gstreamer+mpp play video file long time will be stuck at mpp get_frame

[jasonwxj2009]

Hi,
I use Qt + gstreamer+mpp to play video continuously， about 4 hour later （sometimes less than ），video will stuck，code at mpp.cpp:l326 :
MPP_RET Mpp::get_frame(MppFrame *frame)
if (mOutputTimeout < 0) { /* block wait */ mFrames->wait();
Qt application is dead lock , should be restart！
Is there any solution？

and I have also compile the libs with gstreamer-rockchip and mpp use the newest version
mpp[25815]: mpp_info_test: normal version log:
mpp[25815]: mpp_info: mpp version: unknown mpp version for missing VCS info
mpp[25815]: mpp_info_test: history version log:

The problem is still repeated.

I have used qt+mpv+mpp instead of gstreamer
