Hi Experts
My device happens alognment trap, and av_server.out crashs after several hours.
I need your suggestion to help me find the root cause.
I used "printf()" to find the cause, and found that the issue may be in the VIDENC1_process().
My device uses appro ipnc rdk 3.0, and codec version is H264ENC.version.02.30.00.03.
My application is "Corridor". So i use EDMA to corridor 1080x720 frame to 720x1080, and that means the input frame size of encode is 720x1080.
My simple image flow is below.
My log is also below.
