Hi Dennis, Thank you for your suggestion. I’m confident that adding -pix_fmt yuv420p will help resolve the issue. However, could you kindly assist in providing guidance on how to reproduce the issue or, if not, suggest possible reasons that could have caused this behavior? I need to identify the root cause for reporting to my seniors.
Your help would be greatly appreciated.
