解码h264后编码jpeg出现panic #599

Open handring97 opened 1 month ago

handring97 commented 1 month ago

接收h264网络流后参考mpi_dec_test进行解码，解码后的mppframe转成mppbuffer，使用rga将数据拷贝到MPP编码模块（参考mpi_enc_test）预留的mppbufer中，编码模块拿到mppbufer进行编码jpeg，长时间挂机后出现以下panic信息。复现多次都是在调用encode_put_frame后出现。解码线程中解码异常时有尝试主动调用reset会出现panic，去除reset仍然出现panic。是什么原因造成如此？

这个问题是否可以帮忙分析下呢？目前每次挂机都会出现，出现时间不一定。每次出现问题都是mpp_rkvdec ffb80000.rkvdec: resetting...后触发panic，但是查看系统代码没有主动调用该接口，不清楚是系统内部自行检测触发的还是其他原因

码流信息，接收rtsp h264流，帧率为60fps，解码后进行编码jpeg只能输出43fps左右。
