Mpp decoding error occurs by chance during run (mpp_task_dump_hw_reg)

[leemengwei]

gst-launch-1.0 filesrc location=/home/1702545238.mp4 ! qtdemux ! queue ! h264parse ! mppvideodec format=BGR ! fakesink

In some uncertain case, this command will cause tons of flooding log in /var/log/kernel.log: /orangepi5 kernel: [191343.475715] rk_vcodec: mpp_task_dump_hw_reg:2075 /orangepi5 kernel: [191343.475716] rk_vcodec: mpp_task_dump_hw_reg:2075 /orangepi5 kernel: [191343.475717] rk_vcodec: mpp_task_dump_hw_reg:2075 and finally overwhelm the host machine disk space, making it impossible to keep working.

While the command reports: mpp[169]: mpp: error found on mpp initialization mpp[169]: mpp_buffer: Assertion p->allocator failed at get_group:936 mpp[169]: mpp_hal: mpp_hal_init hal h264d_rkdec init failed ret -1 mpp[169]: mpp_dec: mpp_dec_init could not init hal

Once onccansionally triggered, since the rk_vcodec module is the builtin module, it can only be solved by reboot (modprobe can't work on that). This is a serious bug that will tremendously compromise the RK production series.

allocator failed, is there any dmabuf allocator like dma-heap / drm / ion on the system?

how to check them？ its worth mention that such error occurs by chance。
