DM36XCODECS: Alignment trap after serval hours

Part Number: DM36XCODECS

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.

    Hi ,
    I am not sure of rdk 3.0 , for DM36x latest is 5.1 and 5.0 version , please confirm the version so that others can help.

    Since it is long run issue , codec as been ran for few days in our earlier project there was no crash . I suggest few things since you have few customization,

    Please check Memory leak if any , check available memory at fixed interval after 2, 4, 6 hrs until crash . If there is any constant memory leak that is first place to fix.

    If your running av_server alone , try it under GDB . So that you can get backtrace of all the threads on crash.
